Why Your VPN May Not Be As Secure As It Claims

By BrianKrebs — May 6th 2024 at 14:24

Virtual private networking (VPN) companies market their services as a way to prevent anyone from snooping on your Internet usage. But new research suggests this is a dangerous assumption when connecting to a VPN via an untrusted network, because attackers on the same network could force a target’s traffic off of the protection provided by their VPN without triggering any alerts to the user.

When a device initially tries to connect to a network, it broadcasts a message to the entire local network stating that it is requesting an Internet address. Normally, the only system on the network that notices this request and replies is the router responsible for managing the network to which the user is trying to connect.

The machine on a network responsible for fielding these requests is called a Dynamic Host Configuration Protocol (DHCP) server, which will issue time-based leases for IP addresses. The DHCP server also takes care of setting a specific local address — known as an Internet gateway — that all connecting systems will use as a primary route to the Web.

VPNs work by creating a virtual network interface that serves as an encrypted tunnel for communications. But researchers at Leviathan Security say they’ve discovered it’s possible to abuse an obscure feature built into the DHCP standard so that other users on the local network are forced to connect to a rogue DHCP server.

“Our technique is to run a DHCP server on the same network as a targeted VPN user and to also set our DHCP configuration to use itself as a gateway,” Leviathan researchers Lizzie Moratti and Dani Cronce wrote. “When the traffic hits our gateway, we use traffic forwarding rules on the DHCP server to pass traffic through to a legitimate gateway while we snoop on it.”

The feature being abused here is known as DHCP option 121, and it allows a DHCP server to set a route on the VPN user’s system that is more specific than those used by most VPNs. Abusing this option, Leviathan found, effectively gives an attacker on the local network the ability to set up routing rules that have a higher priority than the routes for the virtual network interface that the target’s VPN creates.

“Pushing a route also means that the network traffic will be sent over the same interface as the DHCP server instead of the virtual network interface,” the Leviathan researchers said. “This is intended functionality that isn’t clearly stated in the RFC [standard]. Therefore, for the routes we push, it is never encrypted by the VPN’s virtual interface but instead transmitted by the network interface that is talking to the DHCP server. As an attacker, we can select which IP addresses go over the tunnel and which addresses go over the network interface talking to our DHCP server.”

Leviathan found they could force VPNs on the local network that already had a connection to arbitrarily request a new one. In this well-documented tactic, known as a DHCP starvation attack, an attacker floods the DHCP server with requests that consume all available IP addresses that can be allocated. Once the network’s legitimate DHCP server is completely tied up, the attacker can then have their rogue DHCP server respond to all pending requests.

“This technique can also be used against an already established VPN connection once the VPN user’s host needs to renew a lease from our DHCP server,” the researchers wrote. “We can artificially create that scenario by setting a short lease time in the DHCP lease, so the user updates their routing table more frequently. In addition, the VPN control channel is still intact because it already uses the physical interface for its communication. In our testing, the VPN always continued to report as connected, and the kill switch was never engaged to drop our VPN connection.”

The researchers say their methods could be used by an attacker who compromises a DHCP server or wireless access point, or by a rogue network administrator who owns the infrastructure themselves and maliciously configures it. Alternatively, an attacker could set up an “evil twin” wireless hotspot that mimics the signal broadcast by a legitimate provider.

ANALYSIS

Bill Woodcock is executive director at Packet Clearing House, a nonprofit based in San Francisco. Woodcock said Option 121 has been included in the DHCP standard since 2002, which means the attack described by Leviathan has technically been possible for the last 22 years.

“They’re realizing now that this can be used to circumvent a VPN in a way that’s really problematic, and they’re right,” Woodcock said.

Woodcock said anyone who might be a target of spear phishing attacks should be very concerned about using VPNs on an untrusted network.

“Anyone who is in a position of authority or maybe even someone who is just a high net worth individual, those are all very reasonable targets of this attack,” he said. “If I were trying to do an attack against someone at a relatively high security company and I knew where they typically get their coffee or sandwich at twice a week, this is a very effective tool in that toolbox. I’d be a little surprised if it wasn’t already being exploited in that way, because again this isn’t rocket science. It’s just thinking a little outside the box.”

Successfully executing this attack on a network likely would not allow an attacker to see all of a target’s traffic or browsing activity. That’s because for the vast majority of the websites visited by the target, the content is encrypted (the site’s address begins with https://). However, an attacker would still be able to see the metadata — such as the source and destination addresses — of any traffic flowing by.

KrebsOnSecurity shared Leviathan’s research with John Kristoff, founder of dataplane.org and a PhD candidate in computer science at the University of Illinois Chicago. Kristoff said practically all user-edge network gear, including WiFi deployments, support some form of rogue DHCP server detection and mitigation, but that it’s unclear how widely deployed those protections are in real-world environments.

“However, and I think this is a key point to emphasize, an untrusted network is an untrusted network, which is why you’re usually employing the VPN in the first place,” Kristoff said. “If [the] local network is inherently hostile and has no qualms about operating a rogue DHCP server, then this is a sneaky technique that could be used to de-cloak some traffic – and if done carefully, I’m sure a user might never notice.”

MITIGATIONS

According to Leviathan, there are several ways to minimize the threat from rogue DHCP servers on an unsecured network. One is using a device powered by the Android operating system, which apparently ignores DHCP option 121.

Relying on a temporary wireless hotspot controlled by a cellular device you own also effectively blocks this attack.

“They create a password-locked LAN with automatic network address translation,” the researchers wrote of cellular hot-spots. “Because this network is completely controlled by the cellular device and requires a password, an attacker should not have local network access.”

Leviathan’s Moratti said another mitigation is to run your VPN from inside of a virtual machine (VM) — like Parallels, VMware or VirtualBox. VPNs run inside of a VM are not vulnerable to this attack, Moratti said, provided they are not run in “bridged mode,” which causes the VM to replicate another node on the network.

In addition, a technology called “deep packet inspection” can be used to deny all in- and outbound traffic from the physical interface except for the DHCP and the VPN server. However, Leviathan says this approach opens up a potential “side channel” attack that could be used to determine the destination of traffic.

“This could be theoretically done by performing traffic analysis on the volume a target user sends when the attacker’s routes are installed compared to the baseline,” they wrote. “In addition, this selective denial-of-service is unique as it could be used to censor specific resources that an attacker doesn’t want a target user to connect to even while they are using the VPN.”

Moratti said Leviathan’s research shows that many VPN providers are currently making promises to their customers that their technology can’t keep.

“VPNs weren’t designed to keep you more secure on your local network, but to keep your traffic more secure on the Internet,” Moratti said. “When you start making assurances that your product protects people from seeing your traffic, there’s an assurance or promise that can’t be met.”

A copy of Leviathan’s research, along with code intended to allow others to duplicate their findings in a lab environment, is available here.

Tech CEO Sentenced to 5 Years in IP Address Scheme

By BrianKrebs — October 17th 2023 at 16:23

Amir Golestan, the 40-year-old CEO of the Charleston, S.C. based technology company Micfo LLC, has been sentenced to five years in prison for wire fraud. Golestan’s sentencing comes nearly two years after he pleaded guilty to using an elaborate network of phony companies to secure more than 735,000 Internet Protocol (IP) addresses from the American Registry for Internet Numbers (ARIN), the nonprofit which oversees IP addresses assigned to entities in the U.S., Canada, and parts of the Caribbean.

Amir Golestan, the former CEO of Micfo.

In 2018, ARIN sued Golestan and Micfo, alleging they had obtained hundreds of thousands of IP addresses under false pretenses. ARIN and Micfo settled that dispute in arbitration, with Micfo returning most of the addresses that it hadn’t already sold.

ARIN’s civil case caught the attention of federal prosecutors in South Carolina, who in May 2019 filed criminal wire fraud charges against Golestan, alleging he’d orchestrated a network of shell companies and fake identities to prevent ARIN from knowing the addresses were all going to the same buyer.

Prosecutors showed that each of those shell companies involved the production of notarized affidavits in the names of people who didn’t exist. As a result, the government was able to charge Golestan with 20 counts of wire fraud — one for each payment made by the phony companies that bought the IP addresses from ARIN.

Golestan initially sought to fight those charges. But on just the second day of his trial in November 2021, Golestan changed his mind and pleaded guilty to 20 counts of wire fraud in connection with the phantom companies he used to secure the IP addresses. Prosecutors estimated those addresses were valued at between $10 million and $14 million.

ARIN says the 5-year sentence handed down by the South Carolina judge “sends an important message of deterrence to other parties contemplating fraudulent schemes to obtain or transfer Internet resources.”

“Those who seek to defraud ARIN (or other Regional Internet Registries) are subject to costly and serious civil litigation, criminal charges, and, ultimately, a lengthy term of incarceration,” reads a statement from ARIN on Golestan’s sentencing.

By 2013, a number of Micfo’s customers had landed on the radar of Spamhaus, a group that many network operators rely upon to stem the tide of junk email. Shortly after Spamhaus started blocking Micfo’s IP address ranges, Micfo shifted gears and began reselling IP addresses mainly to companies marketing “virtual private networking” or VPN services that help customers hide their real IP addresses online.

Golestan did not respond to a request for comment. But in a 2020 interview with KrebsOnSecurity, Golestan claimed that Micfo was at one point responsible for brokering roughly 40 percent of the IP addresses used by the world’s largest VPN providers. Throughout that conversation, Golestan maintained his innocence, even as he explained that the creation of the phony companies was necessary to prevent entities like Spamhaus from interfering with his business going forward.

There are fewer than four billion so-called “Internet Protocol version 4” or IPv4 addresses available for use, but the vast majority of them have already been allocated. The global dearth of available IP addresses has turned them into a commodity wherein each IPv4 address can fetch between $15-$25 on the open market.

This has led to boom times for those engaged in the acquisition and sale of IP address blocks, but it has likewise emboldened those who specialize in absconding with and spamming from dormant IP address blocks without permission from the rightful owners.

The U.S Department of Justice says Golestan will serve 60 months in prison, followed by a 2-year term of court-ordered supervision. The Micfo CEO also was ordered to pay nearly $77,000 in restitution to ARIN for its work in assisting federal prosecutors.

Undersea Cables and Cyber Physical Risks.

By Martin Lee — November 18th 2022 at 09:00

Cyber security implies protecting the confidentiality, availability and integrity of computer systems and networks. Often security researchers and security teams focus on threats to software and the risks associated with authenticating and managing users. However, computing systems are built upon a tall stack of computing resources.  

Each layer within the stack is exposed to specific threats which need to be considered as part of a cyber security strategy. As the threat landscape evolves and exposure to risk changes, organizations need to review their threat exposure and consider if current mitigations are sufficient for their needs. 

The recent disruption of the Nord Stream submarine gas pipeline in the Baltic Sea by an apparent act of sabotage highlights the risks to infrastructure located beneath the waves. The telecommunications infrastructure that carries internet traffic between countries and continents is often provided by submarine cables. These cables are relatively few in number but carry vast amounts of internet and enterprise traffic, potentially from many different service providers. 

The seabed is a challenging environment for infrastructure. Sea water is corrosive, the pressure on the ocean floor can be extreme, while earthquakes, ship’s anchors and dredging provide additional risks to may result in the severing of a cable. Submarine cables are only expected to achieve a lifespan in the region of 25 years before failure.  

Repairing or replacing a submarine cable is expensive and time consuming. It may be many months before a failed cable can be repaired or replaced. In the absence of a functioning cable, internet connections must be rerouted to avoid disruption. However, this risks saturating the remaining infrastructure and adversely affecting the quality of connections.  

Organizations that require high availability international or intercontinental network connections should review their exposure to the risk of submarine cables failure. The nature of this risk will depend on how services are currently delivered.  

  1. Services may be delivered by a single service provider with a guaranteed level of service. In this case, organizations should review their provider’s contingencies in case of loss of one or more submarine cables and verify that these meet requirements.
  2. Piecemeal connections delivered by multiple providers may have been assembled to satisfy needs. Organizations should verify that this connectivity is able to support network requirements if one or more of the connections are unavailable. Organizations should seek to avoid single points of failure such as landing stations or conduits that may be shared by what otherwise appear to be independent connections.
  3. Software-defined Wide Area Networking (SD-WAN) is often used to route traffic in the most efficient manner to meet requirements. The flexibility of the approach implies that the loss of any single physical path would not lead to the loss of connectivity, but the increased flow of data within remaining paths may lead to a degradation in connection quality. Organizations should model how the loss of an undersea cable would affect their services and check if additional redundancy is necessary. 

At the time of writing there is no specific threat to undersea infrastructure. Other than attacks against terrestrial cables, no cable damage has been shown to be due to sabotage. Nevertheless, the Secretary General of NATO has stressed the importance of undersea cables to civilian society and military capability [1]. The British Chief of Defense Staff has warned how seriously intentional damage to telecommunications cables would be taken [2]. 

Physical infrastructure can not be taken for granted. Organizations would do well to review the impact of one or more submarine cables being taken out of service. Preparing response plans and contingencies in advance ensures that disruption is kept to a minimum in the event that such a scenario occurs.

Why 8kun Went Offline During the January 6 Hearings

By BrianKrebs — July 15th 2022 at 19:43

The latest Jan. 6 committee hearing on Tuesday examined the role of conspiracy theory communities like 8kun[.]top and TheDonald[.]win in helping to organize and galvanize supporters who responded to former President Trump’s invitation to “be wild” in Washington, D.C. on that chaotic day. At the same time the committee was hearing video testimony from 8kun founder Jim Watkins, 8kun and a slew of similar websites were suddenly yanked offline. Watkins suggested the outage was somehow related to the work of the committee, but the truth is KrebsOnSecurity was responsible and the timing was pure coincidence.

In a follow-up video address to his followers, Watkins said the outage happened shortly after the Jan. 6 committee aired his brief video testimony.

“Then everything that I have anything to do with seemed to crash, so that there was no way for me to go out and talk to anybody,” Watkins said. “The whole network seemed to go offline at the same time, and that affected a lot of people.”

8kun and many other sites that continue to push the false narrative that the 2020 election was stolen from the 45th president have long been connected to the Internet via VanwaTech, a hosting firm based in Vancouver, Wash. In late October 2020, a phone call to VanwaTech’s sole provider of connectivity to the Internet resulted in a similar outage for 8kun.

Jim Waktins (top right), in a video address to his followers on Tuesday after 8kun was taken offline.

Following that 2020 outage, 8kun and a large number of QAnon conspiracy sites found refuge in a Russian hosting provider. But when the anonymous “Q” leader of QAnon suddenly began posting on 8kun again earlier this month, KrebsOnSecurity received a tip that 8kun was once again connected to the larger Internet via a single upstream provider based in the United States.

On Sunday, July 10, KrebsOnSecurity contacted Psychz Networks, a hosting provider in Los Angeles, to see if they were aware that they were the sole Internet lifeline for 8kun et. al.  Psychz confirmed that in response to a report from KrebsOnSecurity, VanwaTech was removed from its network around the time of the Jan. 6 hearing on Tuesday.

8kun and its archipelago of conspiracy theory communities have once again drifted back into the arms of a Russian hosting provider (AS207651), which is connected to the larger Internet via two providers. Those include AS31500 — which appears to be owned by Russians but is making a fair pretense at being located in the Caribbean; and AS28917, in Vilnius, Lithuania.

8kun’s newfound Russian connections will likely hold, but Lithuania may be a different story. Late last month, pro-Russian hackers claimed responsibility for an extensive distributed denial-of-service (DDoS) attack against Lithuanian state and private websites, which reportedly was in response to Vilnius’s decision to cease the transit of some goods under European Union sanctions to Russia’s Kaliningrad exclave.

Many have speculated that Jim Watkins and/or his son Ron are in fact “Q,” the anonymous persona behind the QAnon conspiracy theory, which held that Former President Trump was secretly working to save the world from a satanic cult of pedophiles and cannibals.

8chan/8kun has been linked to white supremacism, neo-Nazism, antisemitism, multiple mass shootings, and is known for hosting child pornography. After three mass shootings in 2019 revealed the perpetrators had spread their manifestos on 8chan and even streamed their killings live there, 8chan was ostracized by one Internet provider after another.

In 2019, the FBI identified QAnon as a potential domestic terror threat, noting that some of its followers have been linked to violent incidents motivated by fringe beliefs.

Adconion Execs Plead Guilty in Federal Anti-Spam Case

By BrianKrebs — June 11th 2022 at 00:04

At the outset of their federal criminal trial for hijacking vast swaths of Internet addresses for use in large-scale email spam campaigns, three current or former executives at online advertising firm Adconion Direct (now Amobee) have pleaded guilty to lesser misdemeanor charges of fraud and misrepresentation via email.

In October 2018, prosecutors in the Southern District of California named four Adconion employees — Jacob BychakMark ManoogianPetr Pacas, and Mohammed Abdul Qayyum —  in a ten-count indictment (PDF) on felony charges of conspiracy, wire fraud, and electronic mail fraud.

The government alleged that between December 2010 and September 2014, the defendants engaged in a conspiracy to identify or pay to identify blocks of Internet Protocol (IP) addresses that were registered to others but which were otherwise inactive.

Prosecutors said the men also sent forged letters to an Internet hosting firm claiming they had been authorized by the registrants of the inactive IP addresses to use that space for their own purposes.

All four defendants pleaded not guilty when they were charged back in 2018, but this week Bychak, Manoogian and Qayyum each entered a plea deal.

“The defendants’ jobs with Adconion were to acquire fresh IP addresses and employ other measures to circumvent the spam filters,” reads a statement released today by the U.S. Attorney for the Southern District of California, which said the defendants would pay $100,000 in fines each and perform 100 hours of community service.

“To conceal Adconion’s ties to the stolen IP addresses and the spam sent from these IP addresses, the defendants used a host of DBAs, virtual addresses, and fake names provided by the company,” the statement continues. “While defendants touted ties to well-known name brands, the email marketing campaigns associated with the hijacked IP addresses included advertisements such as ‘BigBeautifulWomen,’ ‘iPhone4S Promos,’ and ‘LatinLove[Cost-per-Click].'”

None of the three plea agreements are currently available on PACER, the online federal court document clearinghouse. However, PACER does show that on June 7 — the same day the pleas were entered by the defendants —  the government submitted to the court a superseding set of just two misdemeanor charges (PDF) of fraud in connection with email.

Another document filed in the case says the fourth defendant — Pacas — accepted a deferred prosecution deal, which includes a probationary period and a required $50,000 “donation” to a federal “crime victims fund.”

There are fewer than four billion so-called “Internet Protocol version 4” or IPv4 addresses available for use, but the vast majority of them have already been allocated. The global dearth of available IP addresses has turned them into a commodity wherein each IP can fetch between $15-$25 on the open market.

This has led to boom times for those engaged in the acquisition and sale of IP address blocks, but it has likewise emboldened those who specialize in absconding with and spamming from dormant IP address blocks without permission from the rightful owners.

In May, prosecutors published information about the source of some IP address ranges from which the Adconion employees allegedly spammed. For example, the government found the men leased some of their IP address ranges from a Dutch company that’s been tied to a scandal involving more than four million addresses siphoned from the African Network Information Centre (AFRINIC), the nonprofit responsible for overseeing IP address allocation for African organizations.

In 2019, AFRINIC fired a top employee after it emerged that in 2013 he quietly commandeered millions of IPs from defunct African entities or from those that were long ago acquired by other firms, and then conspired to sell an estimated $50 million worth of the IPs to marketers based outside Africa.

“Exhibit A” in a recent government court filing shows that in 2013 Adconion leased more than 65,000 IP addresses from Inspiring Networks, a Dutch network services company. In 2020, Inspiring Networks and its director Maikel Uerlings were named in a dogged, multi-part investigation by South African news outlet MyBroadband.co.za and researcher Ron Guilmette as one of two major beneficiaries of the four million IP addresses looted from AFRINIC by its former employee.

Exhibit A, from a May 2022 filing by U.S. federal prosecutors.

The address block in the above image — 196.246.0.0/16 — was reportedly later reclaimed by AFRINIC following an investigation. Inspiring Networks has not responded to requests for comment.

Prosecutors allege the Adconion employees also obtained hijacked IP address blocks from Daniel Dye, another man tied to this case who was charged separately. For many years, Dye was a system administrator for Optinrealbig, a Colorado company that relentlessly pimped all manner of junk email, from mortgage leads and adult-related services to counterfeit products and Viagra. In 2018, Dye pleaded guilty to violations of the CAN-SPAM Act.

Optinrealbig’s CEO was the spam king Scott Richter, who changed the name of the company to Media Breakaway after being successfully sued for spamming by AOL, MicrosoftMySpace, and the New York Attorney General Office, among others. In 2008, this author penned a column for The Washington Post detailing how Media Breakaway had hijacked tens of thousands of IP addresses from a defunct San Francisco company for use in its spamming operations.

The last-minute plea deals by the Adconion employees were reminiscent of another recent federal criminal prosecution for IP address sleight-of-hand. In November 2021, the CEO of South Carolina technology firm Micfo pleaded guilty just two days into his trial, admitting 20 counts of wire fraud in connection with an elaborate network of phony companies set up to obtain more than 700,000 IPs from the American Registry for Internet Numbers (ARIN) — AFRINIC’s counterpart in North America.

Adconion was acquired in June 2014 by Amobee, a Redwood City, Calif. online ad platform that has catered to some of the world’s biggest brands. Amobee’s parent firm — Singapore-based communications giant Singtel — bought Amobee for $321 million in March 2012.

But as Reuters reported in 2021, Amobee cost Singtel nearly twice as much in the last year alone — $589 million — in a “non-cash impairment charge” Singtel disclosed to investors. Marketing industry blog Digiday.com reported in February that Singtel was seeking to part ways with its ad tech subsidiary.

One final note about Amobee: In response to my 2019 story on the criminal charges against the Adconion executives, Amobee issued a statement saying “Amobee has fully cooperated with the government’s investigation of this 2017 matter which pertains to alleged activities that occurred years prior to Amobee’s acquisition of the company.”

Yet as the government’s indictment points out, the alleged hijacking activities took place up until September 2014, which was after Amobee’s acquisition of Adconion Direct in June 2014. Also, the IP address ranges that the Adconion executives were prosecuted for hijacking were all related to incidents in 2013 and 2014, which is hardly “years prior to Amobee’s acquisition of the company.”

Amobee has not yet responded to requests for comment.

The Ultimate Guide to Safe Sharing Online

By Jean Treadwell — July 7th 2021 at 13:01

We live in a world that thrives on digital connectivity. According to We Are Social, Canadians are now spending half a day more a month online than they did a year ago. Also, 33 million Canadians logged on to the internet at least once a month in 2020. As more people every year are spending hours upon hours online, they are knowingly (and sometimes unknowingly) unsafely releasing their personal information into the digital ether, making them vulnerable to all sorts of cybercrimes. The ramifications range anywhere from malware infection to identity fraud. Better understanding the best practices for online sharing will ensure users can navigate online dangers and safely connect with others. 

Here are three ways online users share too much information and how they are placing themselves at risk. 

1. Autosaving and Sharing Personal Details 

Think about how many websites you visit regularly. How many of these have access to your personal information, such as your email, credit card numbers, and shipping address? Before accepting the option to save your information on file for a “faster checkout experience,” consider the following: A Canadian Internet Registration Authority polled 500 IT security professionals, and a quarter of them experienced a breach of customer data in 2020. Online users cannot afford to take liberties with the information they hand over to online companies, especially if they subscribe to numerous sites.  

On a similar note, it is equally inadvisable to hand over information about yourself. Although seemingly harmless, online quizzes may not be as safe as you think. Some quiz questions sound more like security questions such as, “What was the first car you owned?” or “Where did you grow up?” Hackers using spyware can access these answers and anything else you enter on quiz sites to formulate informed guesses at your passwords.  

2. Oversharing on Social Media 

It may seem counterintuitive not to share information on social media, seeing as the purpose of these platforms is to share. However, the problem with social media is that too many people are leaving themselves exposed to hackers due to the specificity of the information they share. More than two-thirds of Canadians are on social media, according to Statista, meaning there are millions of user profiles and newsfeeds brimming with personal information. Specific information such as company details in a new job announcement or your birth date in a celebration post are details hackers can use to impersonate you or break into your accounts. Additionally, cybercriminals can impersonate people in your network or pose as average users and add you as a friend. Hackers will often use this tactic to get close to someone and gather intel to formulate a targeted phishing attempt or identity theft. 

While you can take proper precautions to safeguard your personal information, you cannot guarantee that others will do so with the same vigilance. Many do not realize there is more at stake than a loss of privacy when intentionally sharing information, usually login credentials, with others. If your friend you shared your password with is hacked, then a cybercriminal can now access your information as well as theirs. Cybercriminals can then use this information to break into your accounts, hold your data for ransom, and even steal your identity. 

How to Safely Share Online 

Knowing what is safe to share online and how to protect the information that is not is the first step to safeguarding your online presence. Here are four tips to consider before sharing your personal details on websites, social media, and with others: 

1. Verify website and online security 

Always err on the side of caution whenever you visit unknown sites or download applications on your devices. Be aware of what you click on, the ramifications of clicking on a malicious link, or handing over information on an unsecured website. One way to ensure you are visiting a secure website is to look for the padlock icon in the top left corner of your browser. This icon indicates the site and your connection are secure.  

Take your internet protection one step further and avoid saving your information on file. If possible, use an alternate payment gateway with verified encryption that does not require inputting your credit card information. This way, your data does not become a liability in the event of a company data breach.  

2. Rethink your privacy on social media 

There’s a fine line between sharing too much and sharing just enough on social media. Start taking control of your privacy on social media by adjusting your privacy settings. Unless you are an aspiring social media influencer, it is best to keep your account private and limit your followers to only people you know personally. Do not follow strangers and reject friend requests from strangers. They could turn out to be a hacker.  

Take advantage of platform security controls that allow you to control your visible information. For example, you can disable your activity status or geolocations to block other people from tracking your every move or manage the personal data these platforms are allowed to share. Keep in mind that any third-party app with access to these platforms will have varied privacy policies. Read the fine print on their user agreements, as these policies differ depending on the app.

 3. Use a VPN  

Before hopping online, consider using a virtual private network (VPN) to secure your connection. A VPN allows you to browse the internet with the confidence that your Wi-Fi and any sensitive information you send through this connection is encrypted. In other words, if a hacker intercepts this data, they won’t be able to make any sense of it. 

4. Leverage a reliable authentication system 

Enabling multi-factor authentication adds an extra layer of protection that makes it nearly impossible for hackers to bypass even if they do manage to steal your credentials.  

Also, make sure you create strong passwords or passphrases by following password best practices and ensuring they are long, complex, and varied. Use a password manager with a generator to help you create strong passwords and store them, so you do not have to memorize them. This method also makes it easier and more secure than saving passwords on internet browsers. Further, password managers, like McAfee True Key, make it easy to securely share your credentials with others. 

Prioritize Online Safety and Connectivity 

From social media to work to daily activities, peoples’ lives are centralized around their digital devices and online access. Users must learn to care for their information to the same degree one would manage their physical IDs or credit cards. Only then can they carry on their online activities, confident in the knowledge they are doing so securely.

Travel Smart: Protecting Your Family’s Smartphones While on Vacation

By Natalie Maxfield — July 6th 2021 at 13:50

Families are hitting the road again. And it’s absolutely no surprise that they’re taking their smartphones with them. Perhaps what is surprising is that so many of them may be hitting the road without any digital or mobile protection. 

Our recent research shows that 68% of people in the U.S. said that they’re planning to travel for leisure this year, slightly higher than the international average of 64%.1 However, our research also discovered that nearly half of them don’t use mobile security software to protect themselves or their smartphones.  

That lack of protection is a concern, particularly as our April 2021 Threats Report detected a more than 100% increase in attacks aimed at mobile devices. It makes sense that such is the case, as the pandemic led to increased adoption of online activities like banking, shopping, and even doctor visits via telemedicine—often straight from our smartphones.  

However, our smartphones can be as vulnerable as any other device (like our computers). Accordingly, with the volumes of valuable data that those activities create on our smartphones, cyber crooks were sure to follow.  

The good news is that you can indeed enjoy all of that mobile convenience without worry, even on vacation. No doubt many travelers will do some online banking or even some online food ordering while they’re out and about. Likewise, their kids will be online for stretches of that time too, whether it’s on chat apps like Snapchat, social media like Instagram and TikTok, games like Fortnite and Among Us, or streaming videos. Go ahead, do it all. Just make sure you’re protected before you hit the road.  

With that, add mobile protection to your packing list. I’ve put together a shortlist of straightforward things you can do that will help you and your kids stay safe online while on the road this summer.  

Quickly protect your smartphone 

  1. Protect your devices: Just as we’ve learned to protect our computers and laptops from threats, the same holds true for our smartphones and tablets. Whether you protect yours through a mobile security app or as part of the multi-device coverage that comes with your comprehensive security software, mobile protection can alert you of threats and unsecured networks while also adding in the protection of a VPN. 
  2. Use a VPN: A virtual private network (VPN) protects you in two ways. It increases security on public connections, and it increases the protection of your private information while you’re online—particularly important when you shop and bank. Strong VPN protection is a must when you connect to public Wi-Fi while traveling like at airports, hotels, and other vacation rentals where your online activity could be subject to prying eyes. 
  3. Lock up your devices: We talk a great deal about digital security, yet there’s also the physical security of your devices to consider too. After all, devices can get lost or stolen. Take steps to protect your devices by ensuring they’re locked with a PIN or other protection like facial recognition. For your apps, use two-factor authentication wherever possible for extra protection should your device end up in someone else’s hands. 
  4. Enable device tracking: Whether you do this through your phone’s operating system or through a mobile security app, this will help you quickly locate the device’s whereabouts. Additionally, enabling tracking can also give you the power to erase a phone’s data should you have reason to fear that it has really fallen into the wrong hands. 

Special travel advice for the kiddos 

While the tips above are great for the  whole family, the following additional steps are what you can take to protect your children even further:

Online Privacy

Review the location settings on the phone 

Tracking your child’s smartphone not only allows you to find it easily if it’s lost or stolen but can also put you at ease by knowing where your child is.  Yet it’s important to use location tracking selectively. Not every app needs location tracking to work as intended, even though many apps ask for permission to enable it. Go into the phone’s settings and disable the location features on an app-by-app basis.  For example, a weather app doesn’t need your child’s second-by-second location information to work properly, nor should a gaming app need it at all. Likewise, photos taken on a phone can embed location information that can be easily read when shared, revealing plenty about when and where it was taken. In all, enable the location services for only the most necessary of apps like maps. 

Use travel as a time to reset

Recent research shows that tweens spend nearly five hours on their screens each day, while teenagers push that up to more than seven hours a day. Some staycation time is a good time to pare back those hours and enjoy the local scenery, even if for a short stretch. You can use your travel time as well to re-establish your phone rules. That way, vacation stays entertaining but doesn’t affect the habits you set into effect back home. 

Keep tuned in 

Above and beyond security settings and software, there’s you. Get in the habit of talking with your child for a sense of what they’re doing online. As a mom, I like to ask them about their favorite games, share some funny TikTok clips or cute photos with them, and generally make it a point to be a part of their digital lives. It’s great, because it gives you peace of mind knowing what types of things they are doing or interactions they are having online. 

For those of you hitting the road in the coming weeks, enjoy your travels, wherever they take you!
