If only Patch Tuesdays came around infrequently — like total solar eclipse rare — instead of just creeping up on us each month like The Man in the Moon. Although to be fair, it would be tough for Microsoft to eclipse the number of vulnerabilities fixed in this month’s patch batch — a record 147 flaws in Windows and related software.
Yes, you read that right. Microsoft today released updates to address 147 security holes in Windows, Office, Azure, .NET Framework, Visual Studio, SQL Server, DNS Server, Windows Defender, Bitlocker, and Windows Secure Boot.
“This is the largest release from Microsoft this year and the largest since at least 2017,” said Dustin Childs, from Trend Micro’s Zero Day Initiative (ZDI). “As far as I can tell, it’s the largest Patch Tuesday release from Microsoft of all time.”
Tempering the sheer volume of this month’s patches is the middling severity of many of the bugs. Only three of April’s vulnerabilities earned Microsoft’s most-dire “critical” rating, meaning they can be abused by malware or malcontents to take remote control over unpatched systems with no help from users.
Most of the flaws that Microsoft deems “more likely to be exploited” this month are marked as “important,” which usually involve bugs that require a bit more user interaction (social engineering) but which nevertheless can result in system security bypass, compromise, and the theft of critical assets.
Ben McCarthy, lead cyber security engineer at Immersive Labs called attention to CVE-2024-20670, an Outlook for Windows spoofing vulnerability described as being easy to exploit. It involves convincing a user to click on a malicious link in an email, which can then steal the user’s password hash and authenticate as the user in another Microsoft service.
Another interesting bug McCarthy pointed to is CVE-2024-29063, which involves hard-coded credentials in Azure’s search backend infrastructure that could be gleaned by taking advantage of Azure AI search.
“This along with many other AI attacks in recent news shows a potential new attack surface that we are just learning how to mitigate against,” McCarthy said. “Microsoft has updated their backend and notified any customers who have been affected by the credential leakage.”
CVE-2024-29988 is a weakness that allows attackers to bypass Windows SmartScreen, a technology Microsoft designed to provide additional protections for end users against phishing and malware attacks. Childs said one of ZDI’s researchers found this vulnerability being exploited in the wild, although Microsoft doesn’t currently list CVE-2024-29988 as being exploited.
“I would treat this as in the wild until Microsoft clarifies,” Childs said. “The bug itself acts much like CVE-2024-21412 – a [zero-day threat from February] that bypassed the Mark of the Web feature and allows malware to execute on a target system. Threat actors are sending exploits in a zipped file to evade EDR/NDR detection and then using this bug (and others) to bypass Mark of the Web.”
Update, 7:46 p.m. ET: A previous version of this story said there were no zero-day vulnerabilities fixed this month. BleepingComputer reports that Microsoft has since confirmed that there are actually two zero-days. One is the flaw Childs just mentioned (CVE-2024-21412), and the other is CVE-2024-26234, described as a “proxy driver spoofing” weakness.
Satnam Narang at Tenable notes that this month’s release includes fixes for two dozen flaws in Windows Secure Boot, the majority of which are considered “Exploitation Less Likely” according to Microsoft.
“However, the last time Microsoft patched a flaw in Windows Secure Boot in May 2023 had a notable impact as it was exploited in the wild and linked to the BlackLotus UEFI bootkit, which was sold on dark web forums for $5,000,” Narang said. “BlackLotus can bypass functionality called secure boot, which is designed to block malware from being able to load when booting up. While none of these Secure Boot vulnerabilities addressed this month were exploited in the wild, they serve as a reminder that flaws in Secure Boot persist, and we could see more malicious activity related to Secure Boot in the future.”

Adobe today released nine patches tackling at least two dozen vulnerabilities in a range of software products, including Adobe After Effects, Photoshop, Commerce, InDesign, Experience Manager, Media Encoder, Bridge, Illustrator, and Adobe Animate.
KrebsOnSecurity needs to correct the record on a point mentioned at the end of March’s “Fat Patch Tuesday” post, which looked at new AI capabilities built into Adobe Acrobat that are turned on by default. Adobe has since clarified that its apps won’t use AI to auto-scan your documents, as the original language in its FAQ suggested.
“In practice, no document scanning or analysis occurs unless a user actively engages with the AI features by agreeing to the terms, opening a document, and selecting the AI Assistant or generative summary buttons for that specific document,” Adobe said earlier this month.

Malicious hackers are targeting people in the cryptocurrency space in attacks that start with a link added to the target’s calendar at Calendly, a popular application for scheduling appointments and meetings. The attackers impersonate established cryptocurrency investors and ask to schedule a video conference call. But clicking the meeting link provided by the scammers prompts the user to run a script that quietly installs malware on macOS systems.
KrebsOnSecurity recently heard from a reader who works at a startup that is seeking investment for building a new blockchain platform for the Web. The reader spoke on condition that their name not be used in this story, so for the sake of simplicity we’ll call him Doug.
Being in the cryptocurrency scene, Doug is also active on the instant messenger platform Telegram. Earlier this month, Doug was approached by someone on Telegram whose profile name, image and description said they were Ian Lee, from Signum Capital, a well-established investment firm based in Singapore. The profile also linked to Mr. Lee’s Twitter/X account, which features the same profile image.
The investor expressed interest in financially supporting Doug’s startup, and asked if Doug could find time for a video call to discuss investment prospects. Sure, Doug said, here’s my Calendly profile, book a time and we’ll do it then.
When the day and time of the scheduled meeting with Mr. Lee arrived, Doug clicked the meeting link in his calendar but nothing happened. Doug then messaged the Mr. Lee account on Telegram, who said there was some kind of technology issue with the video platform, and that their IT people suggested using a different meeting link.
Doug clicked the new link, but instead of opening up a videoconference app, a message appeared on his Mac saying the video service was experiencing technical difficulties.
“Some of our users are facing issues with our service,” the message read. “We are actively working on fixing these problems. Please refer to this script as a temporary solution.”
Doug said he ran the script, but nothing appeared to happen after that, and the videoconference application still wouldn’t start. Mr. Lee apologized for the inconvenience and said they would have to reschedule their meeting, but he never responded to any of Doug’s follow-up messages.
It didn’t dawn on Doug until days later that the missed meeting with Mr. Lee might have been a malware attack. Going back to his Telegram client to revisit the conversation, Doug discovered his potential investor had deleted the meeting link and other bits of conversation from their shared chat history.
In a post to its Twitter/X account last month, Signum Capital warned that a fake profile pretending to be their employee Mr. Lee was trying to scam people on Telegram.
The file that Doug ran is a simple Apple Script (file extension “.scpt”) that downloads and executes a malicious trojan made to run on macOS systems. Unfortunately for us, Doug freaked out after deciding he’d been tricked — backing up his important documents, changing his passwords, and then reinstalling macOS on his computer. While this a perfectly sane response, it means we don’t have the actual malware that was pushed to his Mac by the script.
But Doug does still have a copy of the malicious script that was downloaded from clicking the meeting link (the online host serving that link is now offline). A search in Google for a string of text from that script turns up a December 2023 blog post from cryptocurrency security firm SlowMist about phishing attacks on Telegram from North Korean state-sponsored hackers.
“When the project team clicks the link, they encounter a region access restriction,” SlowMist wrote. “At this point, the North Korean hackers coax the team into downloading and running a ‘location-modifying’ malicious script. Once the project team complies, their computer comes under the control of the hackers, leading to the theft of funds.”

SlowMist says the North Korean phishing scams used the “Add Custom Link” feature of the Calendly meeting scheduling system on event pages to insert malicious links and initiate phishing attacks.
“Since Calendly integrates well with the daily work routines of most project teams, these malicious links do not easily raise suspicion,” the blog post explains. “Consequently, the project teams may inadvertently click on these malicious links, download, and execute malicious code.”
SlowMist said the malware downloaded by the malicious link in their case comes from a North Korean hacking group dubbed “BlueNoroff, which Kaspersky Labs says is a subgroup of the Lazarus hacking group.
“A financially motivated threat actor closely connected with Lazarus that targets banks, casinos, fin-tech companies, POST software and cryptocurrency businesses, and ATMs,” Kaspersky wrote of BlueNoroff in Dec. 2023.
The North Korean regime is known to use stolen cryptocurrencies to fund its military and other state projects. A recent report from Recorded Future finds the Lazarus Group has stolen approximately $3 billion in cryptocurrency over the past six years.
While there is still far more malware out there today targeting Microsoft Windows PCs, the prevalence of information-stealing trojans aimed at macOS users is growing at a steady clip. MacOS computers include X-Protect, Apple’s built-in antivirus technology. But experts say attackers are constantly changing the appearance and behavior of their malware to evade X-Protect.
“Recent updates to macOS’s XProtect signature database indicate that Apple are aware of the problem, but early 2024 has already seen a number of stealer families evade known signatures,” security firm SentinelOne wrote in January.
According to Chris Ueland from the threat hunting platform Hunt.io, the Internet address of the fake meeting website Doug was tricked into visiting (104.168.163,149) hosts or very recently hosted about 75 different domain names, many of which invoke words associated with videoconferencing or cryptocurrency. Those domains indicate this North Korean hacking group is hiding behind a number of phony crypto firms, like the six-month-old website for Cryptowave Capital (cryptowave[.]capital).
In a statement shared with KrebsOnSecurity, Calendly said it was aware of these types of social engineering attacks by cryptocurrency hackers.
“To help prevent these kinds of attacks, our security team and partners have implemented a service to automatically detect fraud and impersonations that could lead to social engineering,” the company said. “We are also actively scanning content for all our customers to catch these types of malicious links and to prevent hackers earlier on. Additionally, we intend to add an interstitial page warning users before they’re redirected away from Calendly to other websites. Along with the steps we’ve taken, we recommend users stay vigilant by keeping their software secure with running the latest updates and verifying suspicious links through tools like VirusTotal to alert them of possible malware. We are continuously strengthening the cybersecurity of our platform to protect our customers.”
The increasing frequency of new Mac malware is a good reminder that Mac users should not depend on security software and tools to flag malicious files, which are frequently bundled with or disguised as legitimate software.
As KrebsOnSecurity has advised Windows users for years, a good rule of safety to live by is this: If you didn’t go looking for it, don’t install it. Following this mantra heads off a great deal of malware attacks, regardless of the platform used. When you do decide to install a piece of software, make sure you are downloading it from the original source, and then keep it updated with any new security fixes.
On that last front, I’ve found it’s a good idea not to wait until the last minute to configure my system before joining a scheduled videoconference call. Even if the call uses software that is already on my computer, it is often the case that software updates are required before the program can be used, and I’m one of those weird people who likes to review any changes to the software maker’s privacy policies or user agreements before choosing to install updates.
Most of all, verify new contacts from strangers before accepting anything from them. In this case, had Doug simply messaged Mr. Lee’s real account on Twitter/X or contacted Signum Capital directly, he would discovered that the real Mr. Lee never asked for a meeting.
If you’re approached in a similar scheme, the response from the would-be victim documented in the SlowMist blog post is probably the best.

Update: Added comment from Calendly.
Microsoft Corp. today pushed software updates to plug more than 70 security holes in its Windows operating systems and related products, including two zero-day vulnerabilities that are already being exploited in active attacks.
Top of the heap on this Fat Patch Tuesday is CVE-2024-21412, a “security feature bypass” in the way Windows handles Internet Shortcut Files that Microsoft says is being targeted in active exploits. Redmond’s advisory for this bug says an attacker would need to convince or trick a user into opening a malicious shortcut file.
Researchers at Trend Micro have tied the ongoing exploitation of CVE-2024-21412 to an advanced persistent threat group dubbed “Water Hydra,” which they say has being using the vulnerability to execute a malicious Microsoft Installer File (.msi) that in turn unloads a remote access trojan (RAT) onto infected Windows systems.
The other zero-day flaw is CVE-2024-21351, another security feature bypass — this one in the built-in Windows SmartScreen component that tries to screen out potentially malicious files downloaded from the Web. Kevin Breen at Immersive Labs says it’s important to note that this vulnerability alone is not enough for an attacker to compromise a user’s workstation, and instead would likely be used in conjunction with something like a spear phishing attack that delivers a malicious file.
Satnam Narang, senior staff research engineer at Tenable, said this is the fifth vulnerability in Windows SmartScreen patched since 2022 and all five have been exploited in the wild as zero-days. They include CVE-2022-44698 in December 2022, CVE-2023-24880 in March 2023, CVE-2023-32049 in July 2023 and CVE-2023-36025 in November 2023.
Narang called special attention to CVE-2024-21410, an “elevation of privilege” bug in Microsoft Exchange Server that Microsoft says is likely to be exploited by attackers. Attacks on this flaw would lead to the disclosure of NTLM hashes, which could be leveraged as part of an NTLM relay or “pass the hash” attack, which lets an attacker masquerade as a legitimate user without ever having to log in.
“We know that flaws that can disclose sensitive information like NTLM hashes are very valuable to attackers,” Narang said. “A Russian-based threat actor leveraged a similar vulnerability to carry out attacks – CVE-2023-23397 is an Elevation of Privilege vulnerability in Microsoft Outlook patched in March 2023.”
Microsoft notes that prior to its Exchange Server 2019 Cumulative Update 14 (CU14), a security feature called Extended Protection for Authentication (EPA), which provides NTLM credential relay protections, was not enabled by default.
“Going forward, CU14 enables this by default on Exchange servers, which is why it is important to upgrade,” Narang said.
Rapid7’s lead software engineer Adam Barnett highlighted CVE-2024-21413, a critical remote code execution bug in Microsoft Office that could be exploited just by viewing a specially-crafted message in the Outlook Preview pane.
“Microsoft Office typically shields users from a variety of attacks by opening files with Mark of the Web in Protected View, which means Office will render the document without fetching potentially malicious external resources,” Barnett said. “CVE-2024-21413 is a critical RCE vulnerability in Office which allows an attacker to cause a file to open in editing mode as though the user had agreed to trust the file.”
Barnett stressed that administrators responsible for Office 2016 installations who apply patches outside of Microsoft Update should note the advisory lists no fewer than five separate patches which must be installed to achieve remediation of CVE-2024-21413; individual update knowledge base (KB) articles further note that partially-patched Office installations will be blocked from starting until the correct combination of patches has been installed.
It’s a good idea for Windows end-users to stay current with security updates from Microsoft, which can quickly pile up otherwise. That doesn’t mean you have to install them on Patch Tuesday. Indeed, waiting a day or three before updating is a sane response, given that sometimes updates go awry and usually within a few days Microsoft has fixed any issues with its patches. It’s also smart to back up your data and/or image your Windows drive before applying new updates.
For a more detailed breakdown of the individual flaws addressed by Microsoft today, check out the SANS Internet Storm Center’s list. For those admins responsible for maintaining larger Windows environments, it often pays to keep an eye on Askwoody.com, which frequently points out when specific Microsoft updates are creating problems for a number of users.
Authorities in Germany this week seized Internet servers that powered FlyHosting, a dark web offering that catered to cybercriminals operating DDoS-for-hire services, KrebsOnSecurity has learned. FlyHosting first advertised on cybercrime forums in November 2022, saying it was a Germany-based hosting firm that was open for business to anyone looking for a reliable place to host malware, botnet controllers, or DDoS-for-hire infrastructure.
A seizure notice left on the FlyHosting domains.
A statement released today by the German Federal Criminal Police Office says they served eight search warrants on March 30, and identified five individuals aged 16-24 suspected of operating “an internet service” since mid-2021. The German authorities did not name the suspects or the Internet service in question.
“Previously unknown perpetrators used the Internet service provided by the suspects in particular for so-called ‘DDoS attacks’, i.e. the simultaneous sending of a large number of data packets via the Internet for the purpose of disrupting other data processing systems,” the statement reads.
News of a raid on FlyHosting first surfaced Thursday in a Telegram chat channel that is frequented by people interested or involved in the DDoS-for-hire industry, where a user by the name Dstatcc broke the news to FlyHosting customers:
“So Flyhosting made a ‘migration’ with it[s] systems to new rooms of the police ;),” the warning read. “Police says: They support ddos attacks, C&C/C2 and stresser a bit too much. We expect the police will take a deeper look into the files, payment logs and IP’s. If you had a server from them and they could find ‘bad things’ connected with you (payed with private paypal) you may ask a lawyer.”

The German authorities said that as a result of the DDoS attacks facilitated by the defendants, the websites of various companies as well as those of the Hesse police have been overloaded in several cases since mid-2021, “so that they could only be operated to a limited extent or no longer at times.”
The statement says police seized mobile phones, laptops, tablets, storage media and handwritten notes from the unnamed defendants, and confiscated servers operated by the suspects in Germany, Finland and the Netherlands.
In response to questions from KrebsOnSecurity, Germany’s Hessen Police confirmed that the seizures were executed against FlyHosting.
The raids on FlyHosting come amid a broader law enforcement crackdown on DDoS-for-hire services internationally. The U.K.’s National Crime Agency announced last week that it’s been busy setting up phony DDoS-for-hire websites that seek to collect information on users, remind them that launching DDoS attacks is illegal, and generally increase the level of paranoia for people looking to hire such services.
In mid-December 2022, the U.S. Department of Justice (DOJ) announced “Operation Power Off,” which seized four-dozen DDoS-for-hire domains responsible for more than 30 million DDoS attacks, and charged six U.S. men with computer crimes related to their alleged ownership of popular DDoS-for-hire services.
Update, April 3, 9:30 a.m. ET: Added confirmation from Hesse Police.
The United Kingdom’s National Crime Agency (NCA) has been busy setting up phony DDoS-for-hire websites that seek to collect information on users, remind them that launching DDoS attacks is illegal, and generally increase the level of paranoia for people looking to hire such services.
The warning displayed to users on one of the NCA’s fake booter sites. Image: NCA.
The NCA says all of its fake so-called “booter” or “stresser” sites — which have so far been accessed by several thousand people — have been created to look like they offer the tools and services that enable cyber criminals to execute these attacks.
“However, after users register, rather than being given access to cyber crime tools, their data is collated by investigators,” reads an NCA advisory on the program. “Users based in the UK will be contacted by the National Crime Agency or police and warned about engaging in cyber crime. Information relating to those based overseas is being passed to international law enforcement.”
The NCA declined to say how many phony booter sites it had set up, or for how long they have been running. The NCA says hiring or launching attacks designed to knock websites or users offline is punishable in the UK under the Computer Misuse Act 1990.
“Going forward, people who wish to use these services can’t be sure who is actually behind them, so why take the risk?” the NCA announcement continues.
The NCA campaign comes closely on the heels of an international law enforcement takedown involving four-dozen websites that made powerful DDoS attacks a point-and-click operation.
In mid-December 2022, the U.S. Department of Justice (DOJ) announced “Operation Power Off,” which seized four-dozen booter business domains responsible for more than 30 million DDoS attacks, and charged six U.S. men with computer crimes related to their alleged ownership of popular DDoS-for-hire services. In connection with that operation, the NCA also arrested an 18-year-old man suspected of running one of the sites.
According to U.S. federal prosecutors, the use of booter and stresser services to conduct attacks is punishable under both wire fraud laws and the Computer Fraud and Abuse Act (18 U.S.C. § 1030), and may result in arrest and prosecution, the seizure of computers or other electronics, as well as prison sentences and a penalty or fine.
The United Kingdom, which has been battling its fair share of domestic booter bosses, started running online ads in 2020 aimed at young people who search the Web for booter services.
As part of last year’s mass booter site takedown, the FBI and the Netherlands Police joined the NCA in announcing they are running targeted placement ads to steer those searching for booter services toward a website detailing the potential legal risks of hiring an online attack.
Microsoft is sending the world a whole bunch of love today, in the form of patches to plug dozens of security holes in its Windows operating systems and other software. This year’s special Valentine’s Day Patch Tuesday includes fixes for a whopping three different “zero-day” vulnerabilities that are already being used in active attacks.
Microsoft’s security advisories are somewhat sparse with details about the zero-day bugs. Redmond flags CVE-2023-23376 as an “Important” elevation of privilege vulnerability in the Windows Common Log File System Driver, which is present in Windows 10 and 11 systems, as well as many server versions of Windows.
“Sadly, there’s just a little solid information about this privilege escalation,” said Dustin Childs, head of threat awareness at Trend Micro’s Zero Day Initiative. “Microsoft does note that the vulnerability would allow an attacker to exploit code as SYSTEM, which would allow them to completely take over a target. This is likely being chained with a remote code execution bug to spread malware or ransomware. Considering this was discovered by Microsoft’s Threat Intelligence Center, it could mean it was used by advanced threat actors. Either way, make sure you test and roll these fixes quickly.”
The zero-day CVE-2023-21715 is a weakness in Microsoft Office that Redmond describes as a “security feature bypass vulnerability.”
“Microsoft lists this as under active exploit, but they offer no info on how widespread these exploits may be,” Childs said. “Based on the write-up, it sounds more like a privilege escalation than a security feature bypass, but regardless, active attacks in a common enterprise application shouldn’t be ignored. It’s always alarming when a security feature is not just bypassed but exploited. Let’s hope the fix comprehensively addresses the problem.”
The third zero-day flaw already seeing exploitation is CVE-2023-21823, which is another elevation of privilege weakness — this one in the Microsoft Windows Graphic component. Researchers at cybersecurity forensics firm Mandiant were credited with reporting the bug.
Kevin Breen, director of cyber threat research at Immersive Labs, pointed out that the security bulletin for CVE-2023-21823 specifically calls out OneNote as being a vulnerable component for the vulnerability.
“In recent weeks, we have seen an increase in the use of OneNote files as part of targeted malware campaigns,” Breen said. “Patches for this are delivered via the app stores and not through the typical formats, so it’s important to double check your organization’s policies.”
Microsoft fixed another Office vulnerability in CVE-2023-21716, which is a Microsoft Word bug that can lead to remote code execution — even if a booby-trapped Word document is merely viewed in the preview pane of Microsoft Outlook. This security hole has a CVSS (severity) score of 9.8 out of a possible 10.
Microsoft also has more valentines for organizations that rely on Microsoft Exchange Server to handle email. Redmond patched three Exchange Server flaws (CVE-2023-21706, CVE-2023-21707, and CVE-2023-21529), all of which Microsoft says are remote code execution flaws that are likely to be exploited.
Microsoft said authentication is required to exploit these bugs, but then again threat groups that attack Exchange vulnerabilities also tend to phish targets for their Exchange credentials.
Microsoft isn’t alone in dropping fixes for scary, ill-described zero-day flaws. Apple on Feb. 13 released an update for iOS that resolves a zero-day vulnerability in Webkit, Apple’s open source browser engine. Johannes Ullrich at the SANS Internet Storm Center notes that in addition to the WebKit problem, Apple fixed a privilege escalation issue. Both flaws are fixed in iOS 16.3.1.
“This privilege escalation issue could be used to escape the browser sandbox and gain full system access after executing code via the WebKit vulnerability,” Ullrich warned.
On a lighter note (hopefully), Microsoft drove the final nail in the coffin for Internet Explorer 11 (IE11). According to Redmond, the out-of-support IE11 desktop application was permanently disabled on certain versions of Windows 10 on February 14, 2023 through a Microsoft Edge update.
“All remaining consumer and commercial devices that were not already redirected from IE11 to Microsoft Edge were redirected with the Microsoft Edge update. Users will be unable to reverse the change,” Microsoft explained. “Additionally, redirection from IE11 to Microsoft Edge will be included as part of all future Microsoft Edge updates. IE11 visual references, such as the IE11 icons on the Start Menu and taskbar, will be removed by the June 2023 Windows security update (“B” release) scheduled for June 13, 2023.”
For a more granular rundown on the updates released today, see the SANS Internet Storm Center roundup. If today’s updates cause any stability or usability issues in Windows, AskWoody.com will likely have the lowdown on that.
Please consider backing up your data and/or imaging your system before applying any updates. And feel free to sound off in the comments if you experience any problems as a result of these patches.

Our personal and professional lives are becoming increasingly intertwined with the online world. Regular internet usage has made us all prone to cyber-security risks. You leave a digital footprint every time you use the internet, which is a trace of all your online activities.
When you create new accounts or subscribe to different websites, you give them explicit (or implicit, through their family of apps or subsidiary websites) access to your personal and credit card information. In other cases, websites might track basic information without your knowledge, such as your location and search history.
There is an industry of data brokers specifically dedicated to keeping track of user data, packaging it, and supplying it to tech companies who use it to run targeted ads and enhance on-platform user experience. Given the widespread use of the internet and exponential improvements in technology, data has become a valuable commodity — creating a need for the sale and purchase of user data.
This article discusses how data brokers sell your personal information and how you can minimize risk.
Data brokers are companies that aggregate user information from various sources on the internet. They collect, collate, package, and sometimes even analyze this data to create a holistic and coherent version of you online. This data is then supplied to tech companies to fuel their third-party advertising-centered business models.
Companies interested in buying data include but are not limited to:
These companies and social media platforms use your data to better understand target demographics and the content with which they interact. While the practice isn’t unethical in and of itself (personalizing user experiences and creating more convenient UIs are usually cited as the primary reasons for it), it does make your data vulnerable to malicious attacks targeted toward big-tech servers.
Most of your online activities are related. Devices like your phone, laptop, tablets, and even fitness watches are linked to each other. Moreover, you might use one email ID for various accounts and subscriptions. This online interconnectedness makes it easier for data brokers to create a cohesive user profile.
Mobile phone apps are the most common way for data brokerage firms to collect your data. You might have countless apps for various purposes, such as financial transactions, health and fitness, or social media.
A number of these apps usually fall under the umbrella of the same or subsidiary family of apps, all of which work toward collecting and supplying data to big tech platforms. Programs like Google’s AdSense make it easier for developers to monetize their apps in exchange for the user information they collect.
Data brokers also collect data points like your home address, full name, Social Security number, phone number, and date of birth. They have automated scraping tools to quickly collect relevant information from public profiles.[Text Wrapping Break]
Lastly, data brokers can gather data from other third parties that track your cookies or even place trackers or cookies on your browsers. Cookies are small data files that track your online activities when visiting different websites. They track your IP address and browsing history, which third parties can exploit. Cookies are also the reason you see personalized ads and products.
Data brokers collate your private information into one package and sell it to “people search” websites like Spokeo or TruePeopleSearch. You or a tech business can use these websites to search for people and get extensive consumer data. People search sites also contain public records like voter registration information, marriage records, and birth certificates. This data is used for consumer research and large-scale data analysis.
Next, marketing and sales firms are some of data brokers’ biggest clients. These companies purchase massive data sets from data brokers to research your data profile. They have advanced algorithms to segregate users into various consumer groups and target you specifically. Their predictive algorithms can suggest personalized ads and products to generate higher lead generation and conversation percentages for their clients.
We tend to accept the terms and conditions that various apps ask us to accept without thinking twice or reading the fine print. You probably cannot proceed without letting the app track certain data or giving your personal information. To a certain extent, we trade some of our privacy for convenience. This becomes public information, and apps and data brokers collect, track, and use our data however they please while still complying with the law.
There is no comprehensive privacy law in the U.S. on a federal level. This allows data brokers to collect personal information and condense it into marketing insights. While not all methods of gathering private data are legal, it is difficult to track the activities of data brokers online (especially on the dark web). As technology advances, there are also easier ways to harvest and exploit data.
Vermont and California have already enacted laws to regulate the data brokerage industry. In 2018, Vermont passed the country’s first data broker legislation. This requires data brokers to register annually with the Secretary of State and provide information about their data collection activities, opt-out policies, purchaser credentialing practices, and data breaches.
California has passed similar laws to make data brokering a more transparent industry. For risk mitigation of data brokerage, the Federal Trade Commission (FTC) has published reports and provided recommendations to Congress to reduce the engagement of data broker firms. Giving individuals the right to opt-out of the sale of their personal data is a step toward a more rigorous law regarding data privacy.
Some data brokers let you remove your information from their websites. There are also extensive guides available online that list the method by which you can opt-out of some of the biggest data brokering firms. For example, a guide by Griffin Boyce, the systems administrator at Harvard University’s Berkman Klein Center for Internet and Society, provides detailed information on how to opt-out of a long list of data broker companies.
Acxiom, LLC is one of the largest data brokering firms and has collected data for approximately 68% of people who have an online presence. You can opt-out of their data collection either through their website or by calling them directly.
Epsilon Data Management is another big player in the data broker industry that operates as a marketing service and marketing analytics company. You can opt-out of their website through various methods such as by email, phone, and mail. Credit rating agencies like Experian and Equifax are also notorious for collecting your data. Similarly, you can opt-out through their websites or by calling them.
McAfee is a pioneer in providing online and offline data protection to its customers. We offer numerous cybersecurity services for keeping your information private and secure.
With regard to data brokers, we enable users to do a personal data clean-up. Cleaning up your personal data online may be a difficult task, as it requires you to reach out to multiple data brokers and opt out. Instead, sign up for McAfee’s Personal Data Cleanup feature to do a convenient and thorough personal data clean-up. We will search for traces of your personal data and assist in getting it removed.

Sadly, online job scams targeting older adults have been an issue for years. However, in a pandemic job market, cybercriminals are working overtime to devise schemes that exploit job seekers’ need for financial security.
According to the Better Business Bureau, Americans lost more than $62 million in employment scams in 2020. In addition, with federal unemployment benefits ending this month, that number is expected to rise as more people head online to look for work.
Online hiring scams can be hard to detect because scammers advertise job opportunities the same way legitimate employers do—via online ads, job sites, and popular social networking channels. They promise job seekers opportunity and hope but are carefully designed to the applicant’s personal information or deceive them into sending money.
Here are just a few examples of online jobs scams targeting older adults and a few ways to avoid becoming a victim.
Last year the Federal Trade Commission (FTC) identified and shut down a scam on LinkedIn in which a company sent potential job candidates a direct message promising a high-paying job still unpublished to the public. The catch? Potential candidates were asked to pay a fee of up to $2,500 to set up the interview. Variations of this scam, using LinkedIn as a channel, may be in play.
Some scammers are getting especially bold and posting job openings using the names, logos, and even staff names from legitimate companies to lure unsuspecting job seekers into fake interviews. After a questionnaire or interview, the company informs the applicant they have the job. From there, they collect personal information as if it’s part of a legitimate onboarding process—only the job doesn’t exist.
A popular scam involves a company offering job seekers a six-figure income working from home with the promise you can “be your own boss “and “set your own schedule.” The catch: Job seekers must first purchase a starter kit or some form of online coaching package to qualify for the “opportunity.” After that, the company can disappear or charge the consumer thousands of dollars more for training that never comes.
According to the BBB, some scams include job seekers submitting personal information to potential employers only to have that information stolen and used for fraudulent schemes. Some scams even involve online interviews that appeared legitimate; only the interviewer didn’t appear on camera. The bogus employer asks for personal data during the interview, including banking information needed for direct depositing a paycheck.
If an employer attempts to hire you by text, email, or a photo-only video interview, beware. Legitimate employers, no matter how small, will have a professional hiring process. Job Search Safety Tips: 1) Call the company to make sure the job offer is legitimate. 2) Verify the name of the company contact through LinkedIn and verify the person with whom you are communicating 3) Consider comprehensive security software to protect your devices from malware sent via phishing emails from potential employers.
A legitimate employer will not ask for money from a potential or new hire. Nor will they ask you to purchase “training” or cash a check for “software” as part of your employment. Job Search Safety Tip: Check the BBB’s Scam Tracker for scams connected to a company.
If an employer sends you a cashier’s check or even a corporate check, know it may not be real, even if your bank accepts it for a deposit (it won’t clear). Various fake check scams can pull in unwitting victims through job posts that advertise positions for merchandise resellers, virtual assistants, mystery shoppers, car wrappers, caregivers, and photographers.
If an employer immediately asks for personal data such as your SSN, birthdate, driver’s license number, etc., chances are it’s a scam. Job Search Safety Tip: 1) Bank-routing information is for direct deposits after you’ve met an employer in person. If you are applying for remote work, wait for a signed offer, be sure to verify the company and the offer before sharing financial information. 2) Consider using a Virtual Private Network, to share any kind of private information regarding employment.
Job scammers target people who are stressed and desperate for work. If the potential employer seems to be pushing you to give information, send money, or take the next step, it may be a scam. Job Search Safety Tip: Slow down and ask yourself, “Does this sound right?” Seek out the opinion of a friend or relative if needed.
