A Russian man identified by KrebsOnSecurity in January 2022 as a prolific and vocal member of several top ransomware groups was the subject of two indictments unsealed by the Justice Department today. U.S. prosecutors say Mikhail Pavolovich Matveev, a.k.a. “Wazawaka” and “Boriselcin” worked with three different ransomware gangs that extorted hundreds of millions of dollars from companies, schools, hospitals and government agencies.
An FBI wanted poster for Matveev.
Indictments returned in New Jersey and the District of Columbia allege that Matveev was involved in a conspiracy to distribute ransomware from three different strains or affiliate groups, including Babuk, Hive and LockBit.
The indictments allege that on June 25, 2020, Matveev and his LockBit co-conspirators deployed LockBit ransomware against a law enforcement agency in Passaic County, New Jersey. Prosecutors say that on May 27, 2022, Matveev conspired with Hive to ransom a nonprofit behavioral healthcare organization headquartered in Mercer County, New Jersey. And on April 26, 2021, Matveev and his Babuk gang allegedly deployed ransomware against the Metropolitan Police Department in Washington, D.C.
Meanwhile, the U.S. Department of Treasury has added Matveev to its list of persons with whom it is illegal to transact financially. Also, the U.S. State Department is offering a $10 million reward for the capture and/or prosecution of Matveev, although he is unlikely to face either as long as he continues to reside in Russia.
In a January 2021 discussion on a top Russian cybercrime forum, Matveev’s alleged alter ego Wazawaka said he had no plans to leave the protection of “Mother Russia,” and that traveling abroad was not an option for him.
“Mother Russia will help you,” Wazawaka concluded. “Love your country, and you will always get away with everything.”
In January 2022, KrebsOnSecurity published Who is the Network Access Broker ‘Wazawaka,’ which followed clues from Wazawaka’s many pseudonyms and contact details on the Russian-language cybercrime forums back to a 33-year-old Mikhail Matveev from Abaza, RU (the FBI says his date of birth is Aug. 17, 1992).
A month after that story ran, a man who appeared identical to the social media photos for Matveev began posting on Twitter a series of bizarre selfie videos in which he lashed out at security journalists and researchers (including this author), while using the same Twitter account to drop exploit code for a widely-used virtual private networking (VPN) appliance.
“Hello Brian Krebs! You did a really great job actually, really well, fucking great — it’s great that journalism works so well in the US,” Matveev said in one of the videos. “By the way, it is my voice in the background, I just love myself a lot.”
Prosecutors allege Matveev used a dizzying stream of monikers on the cybercrime forums, including “Boriselcin,” a talkative and brash personality who was simultaneously the public persona of Babuk, a ransomware affiliate program that surfaced on New Year’s Eve 2020.
Previous reporting here revealed that Matveev’s alter egos included “Orange,” the founder of the RAMP ransomware forum. RAMP stands for “Ransom Anon Market Place, and analysts at the security firm Flashpoint say the forum was created “directly in response to several large Dark Web forums banning ransomware collectives on their site following the Colonial Pipeline attack by ransomware group ‘DarkSide.”
As noted in last year’s investigations into Matveev, his alleged cybercriminal handles all were driven by a uniquely communitarian view that when organizations being held for ransom decline to cooperate or pay up, any data stolen from the victim should be published on the Russian cybercrime forums for all to plunder — not privately sold to the highest bidder.
In thread after thread on the crime forum XSS, Matveev’s alleged alias “Uhodiransomwar” could be seen posting download links to databases from companies that have refused to negotiate after five days.
Matveev is charged with conspiring to transmit ransom demands, conspiring to damage protected computers, and intentionally damaging protected computers. If convicted, he faces more than 20 years in prison.

Microsoft today released updates to fix nearly 100 security flaws in its Windows operating systems and other software. Highlights from the first Patch Tuesday of 2023 include a zero-day vulnerability in Windows, printer software flaws reported by the U.S. National Security Agency, and a critical Microsoft SharePoint Server bug that allows a remote, unauthenticated attacker to make an anonymous connection.
At least 11 of the patches released today are rated “Critical” by Microsoft, meaning they could be exploited by malware or malcontents to seize remote control over vulnerable Windows systems with little or no help from users.
Of particular concern for organizations running Microsoft SharePoint Server is CVE-2023-21743. This is a Critical security bypass flaw that could allow a remote, unauthenticated attacker to make an anonymous connection to a vulnerable SharePoint server. Microsoft says this flaw is “more likely to be exploited” at some point.
But patching this bug may not be as simple as deploying Microsoft updates. Dustin Childs, head of threat awareness at Trend Micro’s Zero Day Initiative, said sysadmins need to take additional measures to be fully protected from this vulnerability.
“To fully resolve this bug, you must also trigger a SharePoint upgrade action that’s also included in this update,” Childs said. “Full details on how to do this are in the bulletin. Situations like this are why people who scream ‘Just patch it!’ show they have never actually had to patch an enterprise in the real world.”
Eighty-seven of the vulnerabilities earned Redmond’s slightly less dire “Important” severity rating. That designation describes vulnerabilities “whose exploitation could result in compromise of the confidentiality, integrity, or availability of user data, or of the integrity or availability of processing resources.”
Among the more Important bugs this month is CVE-2023-21674, which is an “elevation of privilege” weakness in most supported versions of Windows that has already been abused in active attacks.
Satnam Narang, senior staff research engineer at Tenable, said although details about the flaw were not available at the time Microsoft published its advisory on Patch Tuesday, it appears this was likely chained together with a vulnerability in a Chromium-based browser such as Google Chrome or Microsoft Edge in order to break out of a browser’s sandbox and gain full system access.
“Vulnerabilities like CVE-2023-21674 are typically the work of advanced persistent threat (APT) groups as part of targeted attacks,” Narang said. “The likelihood of future widespread exploitation of an exploit chain like this is limited due to auto-update functionality used to patch browsers.”
By the way, when was the last time you completely closed out your Web browser and restarted it? Some browsers will automatically download and install new security updates, but the protection from those updates usually only happens after you restart the browser.
Speaking of APT groups, the U.S. National Security Agency is credited with reporting CVE-2023-21678, which is another “important” vulnerability in the Windows Print Spooler software.
There have been so many vulnerabilities patched in Microsoft’s printing software over the past year (including the dastardly PrintNightmare attacks and borked patches) that KrebsOnSecurity has joked about Patch Tuesday reports being sponsored by Print Spooler. Tenable’s Narang points out that this is the third Print Spooler flaw the NSA has reported in the last year.
Kevin Breen at Immersive Labs called special attention to CVE-2023-21563, which is a security feature bypass in BitLocker, the data and disk encryption technology built into enterprise versions of Windows.
“For organizations that have remote users, or users that travel, this vulnerability may be of interest,” Breen said. “We rely on BitLocker and full-disk encryption tools to keep our files and data safe in the event a laptop or device is stolen. While information is light, this appears to suggest that it could be possible for an attacker to bypass this protection and gain access to the underlying operating system and its contents. If security teams are not able to apply this patch, one potential mitigation could be to ensure Remote Device Management is deployed with the ability to remotely disable and wipe assets.”
There are also two Microsoft Exchange vulnerabilities patched this month — CVE-2023-21762 and CVE-2023-21745. Given the rapidity with which threat actors exploit new Exchange bugs to steal corporate email and infiltrate vulnerable systems, organizations using Exchange should patch immediately. Microsoft’s advisory says these Exchange flaws are indeed “more likely to be exploited.”
Adobe released four patches addressing 29 flaws in Adobe Acrobat and Reader, InDesign, InCopy, and Adobe Dimension. The update for Reader fixes 15 bugs with eight of these being ranked Critical in severity (allowing arbitrary code execution if an affected system opened a specially crafted file).
For a more granular rundown on the updates released today, see the SANS Internet Storm Center roundup. Nearly 100 updates is a lot, and there are bound to be a few patches that cause problems for organizations and end users. When that happens, AskWoody.com usually has the lowdown.
Please consider backing up your data and/or imaging your system before applying any updates. And please sound off in the comments if you experience any problems as a result of these patches.
Have you ever been browsing online and clicked a link or search result that took you to a site that triggers a “your connection is not private” or “your connection is not secure” error code? If you’re not too interested in that particular result, you may simply move on to another result option. But if you’re tempted to visit the site anyway, you should be sure you understand what the warning means, what the risks are, and how to bypass the error if you need to.
A “your connection is not private” error means that your browser cannot determine with certainty that a website has safe encryption protocols in place to protect your device and data. You can bump into this error on any device connected to the internet — computer, smartphone, or tablet.
So, what exactly is going on when you see the “this connection is not private” error?
For starters, it’s important to know that seeing the error is just a warning, and it does not mean any of your private information is compromised. A “your connection is not private” error means the website you were trying to visit does not have an up-to-date SSL (secure sockets layer) security certificate.
Website owners must maintain the licensing regularly to ensure the site encryption capabilities are up to date. If the website’s SSL certificate is outdated, it means the site owners have not kept their encryption licensing current, but it doesn’t necessarily mean they are up to no good. Even major websites like LinkedIn have had momentary lapses that would throw the error. LinkedIn mistakenly let their subdomain SSL certificates lapse.
In late 2021, a significant provider of SSL certificates, Let’s Encrypt, went out of business. When their root domain officially lapsed, it created issues for many domain names and SSL certificates owned by legitimate companies. The privacy error created problems for unwitting businesses, as many of their website visitors were rightfully concerned about site security.
While it does not always mean a website is unsafe to browse, it should not be ignored. A secure internet connection is critical to protecting yourself online. Many nefarious websites are dangerous to visit, and this SSL certificate error will protect you from walking into them unaware.
SSL certification standards have helped make the web a safer place to transact. It helps ensure online activities like paying bills online, ordering products, connecting to online banking, or keeping your private email accounts safe and secure. Online security continues to improve with a new Transport Layer Security (TLS) standard, which promises to be the successor protocol to SSL.
So be careful whenever visiting sites that trigger the “connection is not private” error, as those sites can potentially make your personal data less secure and make your devices vulnerable to viruses and malware.
Note: The “your connection is not private” error is Google Chrome‘s phrasing. Microsoft Edge or Mozilla Firefox users will instead see a “your connection is not secure” error as the warning message.
If you feel confident that a website or page is safe, despite the warning from your web browser, there are a few things you can do to troubleshoot the error.
Remember, you are taking your chances anytime you ignore an error. As we mentioned, you could leave yourself vulnerable to hackers after your passwords, personal information, and other risks.
Your data and private information are valuable to hackers, so they will continue to find new ways to try and procure it. Here are some ways to protect yourself and your data when browsing online.
As we continue to do more critical business online, we must also do our best to address the risks of the internet’s many conveniences.
A comprehensive cybersecurity tool like McAfee+ Ultimate can help protect you from online scams, identity theft, and phishing attempts, and ensure you always have a secure connection. McAfee helps keep your sensitive information out of the hands of hackers and can help you keep your digital data footprints lighter with personal data cleanup.
With McAfee’s experts on your side, you can enjoy everything the web offers with the confidence of total protection.

With regular marketing emails from brands, businesses, and subscription services, our email accounts are more cluttered than ever. The number of daily emails exchanged globally reached an estimated 319 billion in 2021. Unfortunately, the chances that these emails were spam or junk are quite high. In fact, 45% of all email traffic came from spam emails as of December 2021.
With emails often being the preferred mode of communication for official purposes, it’s important to observe good digital hygiene with your inbox. While a cluttered inbox can be overwhelming, it can also double as a cybersecurity threat. Junk emails that contain malware or act as phishing tools are notorious for wreaking havoc in IT systems or aiding identity theft.
Are you tired of opening your inbox to a barrage of unwanted emails? Read this article to learn how to block or eliminate spam emails.
We know you didn’t sign up to be spammed by unwanted emails. So why is your inbox overflowing with spam messages? It could be one of many reasons, including:
Companies also often share information that you’ve entered during registration with other businesses. Applications for loyalty cards and discount coupons at checkout are also sources of customer information for companies. Although companies are mandated to ask permission before sharing your personal information with affiliates, users often ignore the fine print. So, how do you block these unwanted emails?
Fortunately, most email services let you block this contact or other specific email addresses by following a few simple steps. Usually, just notifying your email service that a certain sender is spamming you does the job. The process varies according to the email provider used. Read on to find out how to keep your inbox clean.
Gmail users can block spam mail using the Gmail app or web app. Follow the steps below to block emails while using the web app:
Open a message from the sender you wish to block. If you don’t have a recent email from them, search their address or name in the search box at the top of the page.
Doing this will cause all future emails from this sender to enter your spam folder. If you block someone you didn’t intend to, follow the same procedure to unblock and start receiving mail from their address.
Follow these steps to block an address using the Outlook (the new Hotmail) web app:
By marking the email as junk, Outlook filters and sends all further emails from the sender to your spam folder.
Like all other service providers, the process of blocking a sender from your Yahoo mail account is quite straightforward. Use your web app and follow these steps to get rid of junk mail from your inbox:
Alternatively, you can also block a sender from the Settings menu.
You can unblock any address by navigating to “Blocked addresses” using the same steps and unblock any ID.
To proactively block senders from your AOL Mail inbox, follow the steps below using your web browser:
Following these simple steps marks all future emails from the chosen sender as spam and sends them to the spam folder.
The Apple iOS email app on iPhone, iPad, and Mac only recently allowed unsubscribing from mailing lists. It still doesn’t let you block senders. Follow the steps detailed below to filter and unsubscribe from senders:
Flag any email as spam by forwarding the email to spam@icloud.com.
Widely used and accepted email services are a frequent target of cyberattacks. Attackers can use email to gain control or access your personal information and resources.
Securing email systems is crucial since your email might contain a lot of sensitive information, including financial documents, legal information, important personal documents, or even trade secrets.
As an email sender and receiver, you should be aware of the most common ways the service is used to infect a computer.
A general rule of thumb is to verify and review download links, forms, and email addresses of the sender before clicking on them, as they can pose significant threats to your cybersecurity. If you receive an email from someone you trust but it contains a link that you find suspicious, multiple websites can analyze URLs and files for malware.
Keeping an email system safe involves securing the servers of the client and the user. As an informal email system user, it can be hard to mitigate and manage risks posed by malicious emails on your own.
Fortunately, you can utilize McAfee+and Identity Theft Protection. McAfee ensures complete cyber protection with advanced monitoring, customized tips according to your usage, and data clean-ups. With multiple subscription plans at your disposal, you can protect yourself and your family from all kinds of cyberthreats.

Are you hoping to buy a house or apply for a car, personal, or business loan at some point? A great credit score helps to achieve all those things. You never know the twists and turns life might take you, so even if these financial milestones aren’t on your radar now, it’s nice to know that a great credit score will open many doors for you when you’re ready. The better your credit score, the more likely you are to get the loan you want at the best interest rate. People spend years (even decades!) working to improve their credit scores to unlock numerous opportunities. In the blink of an eye though, a credit fraudster can erase all that hard work and inflict long-term credit damage. It can cost huge sums to repair and take years to correct.
Many people feel lost on how to prevent these problems or what to do if they suspect identity theft. Luckily, new McAfee services called credit lock and security freeze, which includes credit freeze, are great tools to add to your credit protection toolbelt. They’ll help protect your most personal information from thieves, and both services will help give you the peace of mind you need to confidently go about your day.
Keep reading to learn more about McAfee’s credit lock and security freeze and find out how you can use them to help you from the negative consequences of identity theft.
Credit fraud is a type of identity theft where a criminal uses your information to borrow money, open a new credit or debit card, or uses your card to make purchases that they never intend to pay off. Then, when the loan defaults and the bills stack up, the victim is often left with their credit score in shambles.
According to the FTC, credit fraud is the most common type of identity theft in 2020 and 2021, receiving nearly 18,000 reports from people saying that someone used their information to gain illegal access to their credit card accounts.1
To make sure we’re all on the same page, here are quick definitions of McAfee’s credit lock and security freeze services.
A credit lock and a credit freeze both stop companies from accessing your credit information without your consent when an application for a loan or credit card is submitted. The main difference lies in their speed and credit bureau coverage. By toggling a switch in the McAfee Protection Center, turning on a credit lock is almost instantaneous. A credit freeze can take up to a day to enable or remove; however, it may offer stronger financial loss protection in most U.S. states if an unauthorized line of credit goes through while all three credit bureaus are frozen. Also, McAfee’s credit lock stops one credit bureau from accessing your account, while a credit freeze enables you to halt all three.
Just make sure that you unlock and unfreeze your credit before you do the following:
These are all situations where a bank or creditor will need to access your credit files. Luckily, with significant purchases and financing opportunities like these, you usually plan ahead, so you should have plenty to time to enable access to your credit. To unlock your credit, just click the credit lock toggle. To unlock a freeze, use the same provided links, sign into your account, and follow the instructions from there.
To further help you decide which service may be best for your needs, here are the situations where credit lock and credit freeze would be most helpful.
McAfee credit lock lets you simply toggle on and off one credit bureau’s ability to access your credit report. Usually, filing a lock on your credit with a bureau requires filling out forms and remembering a PIN to apply or remove a lock. Not with McAfee’s credit lock! You can turn a lock on and off at will through the McAfee Protection Center.
Convenience and blazing speed are ideal in situations where you’re worried that a criminal has your personal information and may use it to open accounts in your name that could then damage your well-earned great credit. Some people may choose to always have the credit lock enabled and only unlock it when they’re applying for a credit card or loan. That way, they can feel better about the safety of their credit score.
Credit freeze provides protection and peace of mind just like credit lock; however it enables you to freeze your account at all three major credit bureaus. When creditors check your credit score, they could do so with any credit bureau. If you only freeze one bureau’s access to your information, that still leaves the other two to make inquiries, so it’s important to set up a freeze for each one to cover all your bases.
As mentioned, a credit freeze is just one type of security freeze offered by McAfee. If you’re worried about an identity thief opening not just credit cards, but also utility and/or bank accounts in your name, McAfee’s utility freeze and bank freeze may be additional services for you. Security freeze helps stop unauthorized fraud attempts by giving you quick links and phone numbers. Having all these contact details in one place really speeds up the process and takes the guesswork out of if you’re contacting the correct offices.
Dealing with identity theft or credit fraud is a scary and stressful situation. That’s why McAfee is here with tools that help you protect you. Credit lock and credit freeze may help you feel calmer in a situation of suspected or real identity theft and gives you peace of mind to help prevent credit fraud from happening in the first place. Speed is of the utmost importance when foiling a criminal, so both solutions are easy to use with intuitive design so you’re not wasting time trying to figure out how they work. Plus, neither will affect your credit score. They just stop creditors from looking at your credit files, while you continue to boost your credit with your smart habits.
With both credit lock or credit freeze in your back pocket, you can feel more secure knowing you’re better protected from credit fraud.

This month’s Patch Tuesday offers a little something for everyone, including security updates for a zero-day flaw in Microsoft Windows that is under active attack, and another Windows weakness experts say could be used to power a fast-spreading computer worm. Also, Apple has also quashed a pair of zero-day bugs affecting certain macOS and iOS users, and released iOS 16, which offers a new privacy and security feature called “Lockdown Mode.” And Adobe axed 63 vulnerabilities in a range of products.
Microsoft today released software patches to plug at least 64 security holes in Windows and related products. Worst in terms of outright scariness is CVE-2022-37969, which is a “privilege escalation” weakness in the Windows Common Log File System Driver that allows attackers to gain SYSTEM-level privileges on a vulnerable host. Microsoft says this flaw is already being exploited in the wild.
Kevin Breen, director of cyber threat research at Immersive Labs, said any vulnerability that is actively targeted by attackers in the wild must be put to the top of any patching list.
“Not to be fooled by its relatively low CVSS score of 7.8, privilege escalation vulnerabilities are often highly sought after by cyber attackers,” Breen said. “Once an attacker has managed to gain a foothold on a victim’s system, one of their first actions will be to gain a higher level of permissions, allowing the attacker to disable security applications and any device monitoring. There is no known workaround to date, so patching is the only effective mitigation.”
Satnam Narang at Tenable said CVE-2022-24521 — a similar vulnerability in the same Windows log file component — was patched earlier this year as part of Microsoft’s April Patch Tuesday release and was also exploited in the wild.
“CVE-2022-37969 was disclosed by several groups, though it’s unclear if CVE-2022-37969 is a patch-bypass for CVE-2022-24521 at this point,” Narang said.
Another vulnerability Microsoft patched this month — CVE-2022-35803 — also seems to be related to the same Windows log file component. While there are no indications CVE-2022-35803 is being actively exploited, Microsoft suggests that exploitation of this flaw is more likely than not.
Trend Micro’s Dustin Childs called attention to CVE-2022-34718, a remote code execution flaw in the Windows TCP/IP service that could allow an unauthenticated attacker to execute code with elevated privileges on affected systems without user interaction.
“That officially puts it into the ‘wormable’ category and earns it a CVSS rating of 9.8,” Childs said. “However, only systems with IPv6 enabled and IPSec configured are vulnerable. While good news for some, if you’re using IPv6 (as many are), you’re probably running IPSec as well. Definitely test and deploy this update quickly.”
Cisco Talos warns about four critical vulnerabilities fixed this month — CVE-2022-34721 and CVE-2022-34722 — which have severity scores of 9.8, though they are “less likely” to be exploited, according to Microsoft.
“These are remote code execution vulnerabilities in the Windows Internet Key Exchange protocol that could be triggered if an attacker sends a specially crafted IP packet,” wrote Jon Munshaw and Asheer Malhotra. “Two other critical vulnerabilities, CVE-2022-35805 and CVE-2022-34700 exist in on-premises instances of Microsoft Dynamics 365. An authenticated attacker could exploit these vulnerabilities to run a specially crafted trusted solution package and execute arbitrary SQL commands. The attacker could escalate their privileges further and execute commands as the database owner.”
Not to be outdone, Apple fixed at least two zero-day vulnerabilities when it released updates for iOS, iPadOS, macOS and Safari. CVE-2022-32984 is a problem in the deepest recesses of the operating system (the kernel). Apple pushed an emergency update for a related zero-day last month in CVE-2022-32983, which could be used to foist malware on iPhones, iPads and Macs that visited a booby-trapped website.
Also listed under active attack is CVE-2022-32817, which has been fixed on macOS 12.6 (Monterey), macOS 11.7 (Big Sur), iOS 15.7 and iPadOS 15.7, and iOS 16. The same vulnerability was fixed in Apple Watch in July 2022, and credits Xinru Chi of Japanese cybersecurity firm Pangu Lab.
“Interestingly, this CVE is also listed in the advisory for iOS 16, but it is not called out as being under active exploit for that flavor of the OS,” Trend Micro’s Childs noted. “Apple does state in its iOS 16 advisory that ‘Additional CVE entries to be added soon.’ It’s possible other bugs could also impact this version of the OS. Either way, it’s time to update your Apple devices.”
Apple’s iOS 16 includes two new security and privacy features — Lockdown Mode and Safety Check. Wired.com describes Safety Check as a feature for users who are at risk for, or currently experiencing, domestic abuse.
“The tool centralizes a number of controls in one place to make it easier for users to manage and revoke access to their location data and reset privacy-related permissions,” wrote Lily Hay Newman.
“Lockdown Mode, on the other hand, is meant for users who potentially face targeted spyware attacks and aggressive state-backed hacking. The feature comprehensively restricts any nonessential iOS features so there are as few potential points of entry to a device as possible. As more governments and repressive entities around the world have begun purchasing powerful commodity spyware to target individuals of particular importance or interest, iOS’s general security defenses haven’t been able to keep pace with these specialized threats.”
To turn on Lockdown Mode in iOS 16, go to Settings, then Privacy and Security, then Lockdown Mode. Safety Check is located in the same area.
Finally, Adobe released seven patches addressing 63 security holes in Adobe Experience Manager, Bridge, InDesign, Photoshop, InCopy, Animate, and Illustrator. More on those updates is here.
Don’t forget to back up your data and/or system before applying any security updates. If you experience glitches or problems installing any of these patches this month, please consider leaving a comment about it below; there’s a decent chance other readers have experienced the same and may chime in here with useful tips.
If you’re like most people, you probably use your computer for most of your online activities. It’s amazing what the internet can do to make our lives easier. But if you’ve spent any time online, you know the internet also comes with some risks.
Malware (or malicious software) is one risk of living a connected life. Whether it comes from infected websites, innocent-looking email attachments, or applications and tools you think you can trust, malware can expose your private information to cybercriminals who may use it for personal gain.
If you suspect that malicious software has infected your device, it’s important to remove it quickly to protect yourself.
Though dealing with malware can be scary, there are a few things you can do. This article will explain how malware can infect devices and how you can remove it from them.
There are many types of malware, which do their work in different ways. They can include viruses, worms, Trojans, spyware, adware, ransomware, and more.
Some common ways that Windows PCs, Macs, tablets, and smartphones can get infected include:
Malware can affect you in a variety of ways. For example, malware can allow hackers to steal your private information, uncover passwords, cause financial issues for you or your company, delete files, and render your device unusable.
Malware can also move from your computer to other devices, so you may unwittingly infect friends, family, or co-workers. It can gobble up your computer’s memory, slow its operation to a snail’s pace, and more.
For these reasons, it’s a good idea to find out how to remove malware and learn to protect yourself from it in the first place.
The Federal Trade Commission (FTC) Consumer Information points out some ways to know if malware has infected your device, including if it:
If you think your computer, smartphone or tablet has been infected by malware, the first step is to stop shopping, banking, and doing other things online that involve usernames, passwords, or other sensitive information until you have the problem resolved.
If you don’t have an antivirus program on your device, it’s a good idea to get one. McAfee’s antivirus software provides award-winning protection for your data and devices. It’s important to get antivirus software from a trusted name because some malware can even masquerade as security software.
It’s also important to make sure that your operating system for your different devices and applications are up to date. Older programs and apps might not have the latest security features — cybercriminals are constantly devising new ways to get people’s information — and outdated software can have a harder time fighting off infection.
Once your cybersecurity software is in place, you should:
If you have a PC with Windows 10 or 11, you already benefit from free virus threat protection with Microsoft Windows Defender. Windows Defender, or built-in Microsoft security, compares new files and programs against a database of known malware. It keeps an eye out for signs that an attack is underway, such as the encryption of key files.
Defender can run in active, passive, and disabled mode. In active mode, it’s the primary antivirus app on the device. This means the program will scan files, remedy any threats, and show detected threats in your organization’s security reports and in the Windows Security app.
Microsoft Defender will automatically turn off if you have another antivirus app installed and turned on. Microsoft Defender will turn back on automatically if you uninstall the other app.
In passive mode, Microsoft Defender isn’t used as the primary antivirus app on the device. It’ll scan files and report any threats but it won’t remedy those threats. Finally, Microsoft Windows can’t detect or address threats if it is disabled or uninstalled.
You can run quick and advanced scans in Windows Security. If you’re worried that a specific file or folder has been compromised, you can also run a manual scan by:
You’ll see the scan results and options for dealing with any potential threats.
Microsoft Defender is also available to protect Android smartphones from viruses and malware. It can also help against phishing and phishing and scans your Android device automatically to track and identify potentially unwanted, and dangerous, applications on your device.
Apple users, as well, have built-in antivirus software to help detect and fight off malware. Malware is commonly distributed across macOS systems by being embedded in a harmless-looking app.
Luckily, settings in Security & Privacy preferences allow you to designate the sources of software installed on your Mac. Just follow these steps:
Apple iPads and iPhones have strong built-in security and privacy protections, so it is up to the user on whether or not they want to install antivirus for additional malware protections. Apple boasts a “walled-garden” approach–meaning that their operating system is closed to outside apps and games not affiliated with their official app store unless you jailbreak the device.
Remember that while cybersecurity features built into devices are a great starting point, they’re not always comprehensive. That’s where antivirus software, like McAfee Total Protection, can help. It offers continuous protection against malware, viruses, phishing, ransomware, and other online threats. It also automatically updates so you don’t need to worry about manual upgrades.
The security software also includes alerts before you connect to risky websites and offers one-click fixes to help you stay safe online.
Antivirus software like McAfee works to block malware from infecting your computer, smartphone, or tablet. If malware somehow does get through, it can act as a powerful malware scanner by searching every file on your device for infections.
It can troubleshoot, look for vulnerabilities, and compile a list of infected software that can be quarantined (or isolated) to prevent it from doing harm and deleted at the end of the virus scan using removal tools.
McAfee’s anti-malware software updates its virus database by using an automatic web crawler that scans the internet, identifies online threats like malicious software, and figures out how to delete them.
McAfee antivirus uses this data to automatically update your device’s protective set-upl, providing strong protection so nothing harmful gets in.
Besides desktop computers, McAfee provides mobile security for both Android and Apple devices. For example, when you use your iPhone or Android phone on a public Wi-Fi system, McAfee’s Wi-Fi privacy protection (VPN) in effect turns the public network into a private one, where you can surf safely. Of course, its antivirus app regularly scans for threats and malware while actively blocking them in real time, keeping your mobile devices protected.

I think it’s fair to say that come to next Australia Day, there needs to be a special award category for parents of young children who survived home learning during the lockdowns. Let’s be honest – it’s been brutal! So many parents had to juggle their own full-time work, running a household, AND supervising a day’s worth of learning for often, multiple children! Research from Macquarie University showed that many parents spent up to 14 hours a week in their role as home learning managers and 9/10 parents reported the experience as, quite understandably, stressful! As a mum of older teens and young adults – who are usually self-sufficient – I’m in awe!
But the good news is – things are on the improve! Our vaccine rates are amongst the best in the world, so lockdowns have been lifted and, drum roll… kids are back at school! I’ve always been a big fan of trying to find the silver lining of any situation and I think there are many we can take away from our COVID experience, particularly when it comes to digital parenting. I know of so many parents who have completely rethought their approach to managing kids and technology since the pandemic hit because of their home learning experience.
So, in the spirit of sharing and caring, I thought I’d round up some of the best ‘aha’ moments from parents who were forced to become expert home learning managers over multiple lockdowns. And make sure you take notes because there are some great learnings that we can apply to our digital parenting journey.
If you have never been ‘all in’ with your kids’ use of technology for both learning and socializing, then you need to get over this ASAP. Technology is the lifeblood of your kids’ lives. It’s how they connect, nurture friendships, and organize their social lives. I also recommend parents try to see technology through the eyes of their kids NOT just through our more ‘mature’ lens. It’s the best way of truly understanding just what a huge role it plays in their day-to-day lives. And don’t forget that technology is almost always used to set up in-person catchups! So, please don’t demonize it, it will only push your kids away.
I totally appreciate that many parents didn’t choose to be home learning ‘managers’ however many have shared with me how they now feel far more involved in their child’s life because of the experience. Seeing first-hand how your child’s day works, overhearing their conversations with teachers and peers (courtesy of Zoom), and being blown away by your offspring’s tech skills has given many parents incredible insight into their child.
I know of parents who have noticed learning issues and friendship problems all as a result of their home learning manager role! There’s nothing like being able to nip something in the bud before it becomes a big issue! So, stay involved and you’ll reap the rewards!
Confession – I have never been one of those parents who proactively organized park visits, bushwalks, and exercise regimes for my kids. But many of the parents who managed young children through a lockdown and resorted to becoming personal trainers reported that it paid dividends. So, now lockdowns are (hopefully!) history, don’t forget about the benefits of getting your kids to move. It’s hard to be on a screen when you are walking the dog, playing a game of family cricket, or bushwalking. I know it’s time-consuming but it’s so worth it!
As of 2 years ago, the average Aussie household had 17 internet-connected devices in tow so it’s no wonder keeping abreast of all the devices in your household feels like a full-time job! But with kids continuing to use their devices for both study and socializing, it’s essential that you give each device a ‘once over’ to minimize risks and prevent issues arising down the track.
Ensuring all their software is up to date is a great place to start. Also check that the default password has been changed and that there is some top-shelf security software installed to protect the device and, most importantly, its user! And while you are there, why not also ensure that each of their online accounts has its own distinct password? If you think they could manage a password manager, then it might be time to introduce them to one? Check out McAfee’s True Key – I couldn’t manage without it!
I think you’d be hard-pressed to find many parents keen to return to home learning. In fact, I think there may even be a revolt if we had to go back! But, knowing we have picked up some ‘nuggets of gold’ along the way makes it a little feel a little better! So, please embrace technology – it’s a fantastic way of connecting with your kids. But of course, keep your family’s usage in check and minimize the risks by giving each device a once-over.
Happy Digital Parenting!

What do Burger King and the popular “Doge” meme have in common? They both have cryptocurrencies named after their likeliness. WhopperCoin and Dogecoin are just two examples of the thousands of types of cryptocurrencies that have caught users’ attention over the past few years. Cryptocurrencies are digital tokens generated by a computer after solving complex mathematical functions. These functions are used to verify the authenticity of a ledger, or blockchain.
Bitcoin is the most popular cryptocurrency today, increasing its value by almost 300% in 2020. Today, almost 46 million Americans own at least one share of Bitcoin, illustrating how these cryptocurrencies are the future of tomorrow’s digital payment system — or are they? The same benefits that make them a popular choice with online users have also made them popular amongst online thieves, sparking a wave of ransomware attacks and other cyberattacks more recently. This begs the question: do the benefits of Bitcoin outweigh the risks?
Every rose has its thorn, and several Bitcoin benefits seem to be hitched to online security risks. Here are some cryptocurrency characteristics that may seem appealing to users, but also provide cybercriminals with an opportunity to exploit:
As previously mentioned, cryptocurrency exchanges take place on an online public ledger, or blockchain, to secure online transactions. This means that anybody can observe the exchange online. However, the parties making the transactions are anonymous, disguised with a random number. Bitcoin users can make purchases that are never associated with their identity, similar to a cash transaction.
While the purchase discretion provided by Bitcoin may be appealing to users who want to remain private, this characteristic could also aid cybercriminals in malicious activity. Due to the anonymity of Bitcoin transactions, there is no way for someone to associate a person with a certain cryptocurrency wallet. Furthermore, a user could have multiple wallets, allowing them to spread their currency from one address to another.
For a cybercriminal looking to target an individual with ransomware, the purchase discretion and anonymity of Bitcoin provide a favorable solution. In fact, Bitcoin accounts for approximately 98% of ransomware payments today. Say a hacker carries out a ransomware attack and demands that the user pay a large sum in Bitcoin. If the user completes the payment, the hacker can keep moving the currency from one anonymous account to another. That makes it very difficult — though not impossible — to trace if the individual decides to investigate the case and tries to get their money back.
Another characteristic that Bitcoin users find appealing is the autonomy offered by digital currencies. In theory, they allow users more autonomy over their own money than government-regulated currencies do. With Bitcoin, users can control how they spend their money without dealing with an intermediary authority like a bank or government.
This lack of intermediary authority also opens a door for hackers to exploit. Say a user decides that they want to manage their finances using Bitcoin to bypass banking fees and send money to friends and family in different parts of the world. As previously mentioned, a Bitcoin user is assigned an anonymous private key that acts as their security credential. This key is generated and maintained by the user instead of a third-party agency. But what happens if the key isn’t random enough? An attacker could steal the user’s private key, and they will not be able to recover it since the Bitcoin blockchain is not dependent on any centralized third-party institutions. Therefore, it will be very difficult to track the attacker’s behaviors and recover lost funds.
It is safe to say that Bitcoin has caused a lot of buzz. But do the benefits outweigh the risks? Due to the nature of Bitcoin and most other public blockchains, anyone in the world can perform transactions or cryptographic computations — including cybercriminals. That’s why it is crucial for current cryptocurrency users and those considering cryptocurrency investment to do their research and know what vulnerabilities lie within the world of Bitcoin.
Follow these tips to help protect yourself from common threats that leverage cryptocurrency:
With blockchain, cryptocurrency, and any new and emerging technology, make sure you always remain a bit skeptical. Do your homework before you embrace the technology — research your options and make note of any known security issues and what you can do to mitigate known risks.
If a hacker does target you with ransomware demanding Bitcoin payment, it’s best not to pay the ransom. Although you may feel in the moment that this is the only way to get your encrypted files back, there is no guarantee that the ransomware developers will send a decryption tool once they receive the payment. Paying the ransom also contributes to the development of more ransomware families, so it is best to hold off on making any payments. Furthermore, a recent study found that 80% of businesses that choose to pay a ransom experience a subsequent ransomware attack. While it may feel like your only option in the moment, paying a ransom could show attackers that you’re willing to make the payment, therefore positioning you as an ideal target for yet another attack.
If you are targeted with ransomware, it’s crucial that you always have backup copies of your files, preferably in the cloud and on an external hard drive. This way, if you do get a ransomware infection, you can wipe your computer or device and reinstall your files from the backup. Backups protect your data, and you won’t be tempted to reward the hackers by paying a ransom. Backups won’t prevent ransomware, but they can mitigate the risks.
Large organizations often fall prey to ransomware attacks, so take necessary precautions if a company you’ve interacted with becomes compromised from a data leak or a ransomware attack. Immediately change your passwords for all your accounts, ensuring they are strong and unique. You can also employ a password manager to keep track of your credentials and generate secure login keys.
Add an extra layer of security with a solution such as McAfee® Total Protection, which includes Ransom Guard, to help protect your devices from these cyberthreats and ensure your digital wellness online.
The emergence of Bitcoin has indeed facilitated a wave of cybercrime that was previously difficult to perceive. In this new age of digital payments, blockchain, and cryptocurrencies, make sure that you do your research and stay vigilant when it comes to protecting your online safety. Remember: Bitcoin worth will continue to fluctuate, but your personal security will always remain invaluable.

How public-key cryptography works Public-key or asymmetric cryptography is one of the two main types of encryption algorithms. Its names come from the fact that it uses two different encryption keys: a public one and a private one. Public and private keys The private key used in public-key cryptography is a random number with certain […]

Welcome to the new normal. We’re all now living in a post-COVID-19 world characterized by uncertainty, mass home working and remote learning. The lines demarcating normal life have shifted abruptly – perhaps never to return. That’s not the worst that can happen, as we all know, but it does mean we all need to get used to new ways of living, working and studying from home. This has major implications for the online safety, security and privacy of our families.
To help you adapt to these new conditions while protecting what matters most, Trend Micro has developed a two-part blog series on “The New Normal.” Part 1 identifies the scope and specific cyber-threats of the new normal. Part 2 provides security tips and products to help address those threats.
In April, nearly 300 million Americans were estimated to be in government-mandated lockdown. Even as some businesses, municipalities and states begin to relax these rules, experts have warned of subsequent waves of the virus, which could result in new localized lockdowns. In short, a lot of people will continue to work from home, while their children, also at home, attempt to study remotely from their mobile devices.
This has considerable implications for how we spend our time. Without that morning commute to work or school, more of it than ever will involve sitting in front of a desktop, laptop, tablet or smartphone screen. Even the smart TV is enlisted. Dangers include

Unfortunately, the increase in working from home (WFH), especially for those not used to it, may lead to an increase in risky behavior, such as: using non-approved apps for work; visiting non work-related sites on work devices; and using personal devices to access work resources. Recent global Trend Micro research found that:

This is not about restricting your freedom to visit the sites you want to visit while at home. It’s about reducing the risk of exposing corporate data and systems to possible malware.
Unsurprisingly, there has also been a major uptick in the volume of cyber-threats targeting home users. With a captive audience to aim at, it’s a huge opportunity for cyber-criminals to steal your log-ins and personal data to sell to fraudsters, or even to steal corporate passwords and information for a potentially bigger pay-off. They are helped by the fact that many home workers may be more distracted than they usually would be at the office, especially if they have young children. Your kids may even share the same laptops or PCs as you, potentially visiting risky sites and/or downloading unapproved apps.
There’s also a chance that, unless you have a corporate machine at home, your personal computing equipment is less secure than the kit you had in the office. Add to that the fact that support from the IT department may be less forthcoming than usual, given that stretched teams are overwhelmed with requests, while themselves struggling to WFH. One recent report claimed that nearly half (47%) of IT security pros have been taken off some or all of their typical security tasks to support other IT-related jobs. In another, only 59% of respondents said they believe their cybersecurity team has the right tools and resources at home to perform their job effectively.
It’s time to step up and take security into your own hands. Stay on the lookout for the following threats.
