As millions of people around the world practice social distancing and work their office jobs from home, video conferencing has quickly become the new norm. Whether you’re attending regular work meetings, partaking in a virtual happy hour with friends, or catching up with extended family across the globe, video conferencing is a convenient alternative to many of the activities we can no longer do in real life. But as the rapid adoption of video conferencing tools and apps occurs, is security falling by the wayside?
One security vulnerability that has recently made headlines is the ability for uninvited attendees to bombard users’ virtual meetings. How? According to Forbes, many users have posted their meeting invite links on social media sites like Twitter. An attacker can simply click on one of these links and interrupt an important conference call or meeting with inappropriate content.
Online conferencing tools allow users to hold virtual meetings and share files via chat. But according to Security Boulevard, communicating confidential business information quickly and privately can be challenging with these tools. For example, users are not always immediately available, even when working from home. In fact, many parents are simultaneously doubling as working parents and teachers with the recent closure of schools and childcare providers. If a user needs to share private information with a coworker but they are unable to connect by video or phone, they might revert to using a messaging platform that lacks end-to-end encryption, a feature that prevents third-party recipients from seeing private messages. This could lead to leaks or unintended sharing of confidential data, whether personal or corporate. What’s more, the lack of using a secure messaging platform could present a hacker with an opportunity to breach a victim’s data or device. Depending on the severity of this type of breach, a victim could be at risk of identity theft.
With the recent surge of new video conferencing users, privacy policies have been placed under a microscope. According to WIRED, some online conferencing tools have had to update their policies to reflect the collection of user information and meeting content used for advertising or other marketing efforts. Another privacy concern was brought to light by a video conferencing tool’s attention-tracking feature. This alerts the virtual meeting host when an attendee hasn’t had the meeting window in their device foreground for 30 seconds, resulting in users feeling that their privacy has been compromised.
As users become accustomed to working from home, video conferencing tools will continue to become a necessary avenue for virtual communication. But how can users do so while putting their online security first? Follow these tips to help ensure that your virtual meetings are safeguarded:
There are plenty of video conferencing tools available online. Before downloading the first one you see, do your research and check for possible security vulnerabilities around the tools. Does the video conferencing tool you’re considering use end-to-end encryption? This ensures that only meeting participants have the ability to decrypt secure meeting content. Additionally, be sure to read the privacy policies listed by the video conferencing programs to find the one that is the most secure and fits your needs.
To ensure that only invited attendees can access your meeting, make sure they are password protected. For maximum safety, activate passwords for new meetings, instant meetings, personal meetings, and people joining by phone.
To keep users (either welcome or unwelcome) from taking control of your screen while you’re video conferencing, select the option to block everyone except the host (you) from screen sharing.
By turning on automatic updates, you are guaranteed to have all the latest security patches and enhancements for your video conferencing tool as soon as they become available.

Costa Rica’s national health service was hacked sometime earlier this morning by a Russian ransomware group known as Hive. The intrusion comes just weeks after Costa Rican President Rodrigo Chaves declared a state of emergency in response to a data ransom attack from a different Russian ransomware gang — Conti. Ransomware experts say there is good reason to believe the same cybercriminals are behind both attacks, and that Hive has been helping Conti rebrand and evade international sanctions targeting extortion payouts to cybercriminals operating in Russia.
The Costa Rican publication CRprensa.com reports that affected systems at the Costa Rican Social Security Fund (CCSS) were taken offline on the morning of May 31, but that the extent of the breach was still unclear. The CCSS is responsible for Costa Rica’s public health sector, and worker and employer contributions are mandated by law.
A hand-written sign posted outside a public health center in Costa Rica today explained that all systems are down until further notice (thanks to @Xyb3rb3nd3r for sharing this photo).
A hand-written notice posted outside a public health clinic today in Costa Rica warned of system outages due to a cyberattack on the nation’s healthcare systems. The message reads: “Dear Users: We would like to inform you that due a problem related to the information systems of the institution, we are unable to expend any medicine prescriptions today until further notice. Thank you for your understanding- The pharmacy.”
Esteban Jimenez, founder of the Costa Rican cybersecurity consultancy ATTI Cyber, told KrebsOnSecurity the CCSS suffered a cyber attack that compromised the Unique Digital Medical File (EDUS) and the National Prescriptions System for the public pharmacies, and as a result medical centers have turned to paper forms and manual contingencies.
“Many smaller health centers located in rural areas have been forced to close due to not having the required equipment or communication with their respective central health areas and the National Retirement Fund (IVM) was completely blocked,” Jimenez said. “Taking into account that salaries of around fifty thousand employees and deposits for retired citizens were due today, so now the payments are in danger.”
Jimenez said the head of the CCSS has addressed the local media, confirming that the Hive ransomware was deployed on at least 30 out of 1,500 government servers, and that any estimation of time to recovery remains unknown. He added that many printers within the government agency this morning began churning out copies of the Hive ransom note.

“HIVE has not yet released their ransom fee but attacks are expected to follow, other organizations are trying to get a hold on the emergency declaration to obtain additional funds to purchase new pieces of infrastructure, improve their backup structure amongst others,” Jimenez said.
A copy of the ransom note left behind by the intruders and subsequently uploaded to Virustotal.com indicates the CCSS intrusion was the work of Hive, which typically demands payment for a digital key needed to unlock files and servers compromised by the group’s ransomware.

On May 8, President Chaves used his first day in office to declare a national state of emergency after the Conti ransomware group threatened to publish gigabytes of sensitive data stolen from Costa Rica’s Ministry of Finance and other government agencies. Conti initially demanded $10 million, and later doubled the amount when Costa Rica refused to pay. On May 20, Conti leaked more than 670 gigabytes of data taken from Costa Rican government servers.
As CyberScoop reported on May 17, Chaves told local media he believed that collaborators within Costa Rica were helping Conti extort the government. Chaves offered no information to support this claim, but the timeline of Conti’s descent on Costa Rica is worth examining.
Most of Conti’s public communications about the Costa Rica attack have very clearly assigned credit for the intrusion to an individual or group calling itself “unc1756.” In March 2022, a new user by the same name registered on the Russian language crime forum Exploit.
A message Conti posted to its dark web blog on May 20.
On the evening of April 18, Costa Rica’s Ministry of Finance disclosed the Conti intrusion via Twitter. Earlier that same day, the user unc1756 posted a help wanted ad on Exploit saying they were looking to buy access to “special networks” in Costa Rica.
“By special networks I mean something like Haciendas,” unc1756 wrote on Exploit. Costa Rica’s Ministry of Finance is known in Spanish as the “Ministerio Hacienda de Costa Rica.” Unc1756 said they would pay $USD 500 or more for such access, and would work only with Russian-speaking people.
Experts say there are clues to suggest Conti and Hive are working together in their attacks on Costa Rica, and that the intrusions are tied to a rebranding effort by Conti. Shortly after Russia invaded Ukraine at the end of February, Conti declared its full support, aligning itself directly with Russia and against anyone who would stand against the motherland.
Conti’s threatening message this week regarding international interference in Ukraine.
Conti quickly deleted the declaration from its website, but the damage had already been done, and any favor or esteem that Conti had earned among the Ukrainian cybercriminal underground effectively evaporated overnight.
Shortly thereafter, a Ukrainian security expert leaked many months worth of internal chat records between Conti personnel as they plotted and executed attacks against hundreds of victim organizations. Those candid messages exposed what it’s like to work for Conti, how they undermined the security of their targets, as well as how the group’s leaders strategized for the upper hand in ransom negotiations.
But Conti’s declaration of solidarity with the Kremlin also made it increasingly ineffective as an instrument of financial extortion. According to cyber intelligence firm ADVIntel, Conti’s alliance with the Russian state soon left it largely unable to receive ransom payments because victim companies are being advised that paying a Conti ransom demand could mean violating U.S. economic sanctions on Russia.
“Conti as a brand became associated with the Russian state — a state that is currently undergoing extreme sanctions,” ADVIntel wrote in a lengthy analysis (PDF). “In the eyes of the state, each ransom payment going to Conti may have potentially gone to an individual under sanction, turning simple data extortion into a violation of OFAC regulation and sanction policies against Russia.”

ADVIntel says it first learned of Conti’s intrusion into Costa Rican government systems on April 14, and that it has seen internal Conti communications indicating that getting paid in the Costa Rica attack was not the goal.
Rather, ADVIntel argues, Conti was simply using it as a way to appear publicly that it was still operating as the world’s most lucrative ransomware collective, when in reality the core Conti leadership was busy dismantling the crime group and folding themselves and top affiliates into other ransomware groups that are already on friendly terms with Conti.
“The only goal Conti had wanted to meet with this final attack was to use the platform as a tool of publicity, performing their own death and subsequent rebirth in the most plausible way it could have been conceived,” ADVIntel concluded.
ADVIntel says Conti’s leaders and core affiliates are dispersing to several Conti-loyal crime collectives that use either ransomware lockers or strictly engage in data theft for ransom, including AlphV/BlackCat, AvosLocker, BlackByte, HelloKitty, Hive, and Karakurt.
Still, Hive appears to be perhaps the biggest beneficiary of any attrition from Conti: Twice over the past week, both Conti and Hive claimed responsibility for hacking the same companies. When the discrepancy was called out on Twitter, Hive updated its website to claim it was not affiliated with Conti.
Conti and Hive’s Costa Rican exploits mark the latest in a string of recent cyberattacks against government targets across Latin America. Around the same time it hacked Costa Rica in April, Conti announced it had hacked Peru’s National Directorate of Intelligence, threatening to publish sensitive stolen data if the government did not pay a ransom.
But Conti and Hive are not alone in targeting Latin American victims of late. According to data gathered from the victim shaming blogs maintained by multiple ransomware groups, over the past 90 days ransom actors have hacked and sought to extort 15 government agencies in Brazil, nine in Argentina, six in Colombia, four in Ecuador and three in Chile.
A recent report (PDF) by the Inter-American Development Bank suggests many Latin American countries lack the technical expertise or cybercrime laws to deal with today’s threats and threat actors.
“This study shows that the Latin American and Caribbean (LAC) region is not sufficiently prepared to handle cyberattacks,” the IADB document explains. “Only 7 of the 32 countries studied have a critical infrastructure protection plan, while 20 have established cybersecurity incident response teams, often called CERTs or CSIRTs. This limits their ability to identify and respond to attacks.”

It’s a great feeling when a wearable fitness device vibrates to let you know when you hit the day’s fitness goal. The digital fireworks display that lights up your watch’s screen is a signal that you should keep on moving to challenge yourself more … or spend the rest of the day on the couch guilt-free.
While fitness wearable devices, trackers, and apps are excellent motivators for you, cybercriminals love them for their vulnerabilities and privacy loopholes. This doesn’t mean you have to chuck your expensive watch in the bin or delete your fitness apps from your smartphone. Awareness and smart habits go a long way in deterring cybercriminals. Keep reading to learn more about wearable technology vulnerabilities and how you can sidestep each.
Many fitness tracker apps and wearables are equipped with GPS. At the end of a run or long walk, you can view your exact route, sometimes with detailed maps that show street and town names. This tracking feature was potentially dangerous back in 2018 when a fitness app released a heat map of all its users’ running routes for the year, which clearly outlined secret military bases.1
Even if you’re stationed in a suburb and not hostile territory, you may consider the risks of sharing your location data. A determined criminal who has time to spare can guess your address and see the times of days when you’re commonly out at the gym or on a run.
When you purchase a wearable fitness device, you often have to pair it with an accompanying smartphone app to see your daily stats and tailor your fitness goals. Think about all the personally identifiable information (PII) that app now houses: your full name, password, address, height, weight, location, medical concerns, daily activity patterns, etc. In the hands of a cybercriminal, this information can bring a nefarious actor one step closer to impersonating you. Plus, if your health data makes it onto the dark web or is sold to health companies, it may result in serious privacy concerns.
Luckily, there are ways to get peace of mind about the security of your identity. Identity protection services, such as McAfee Identity Monitoring Service, provide expert identity theft support and up to $1 million in identity theft coverage.
Wearable devices complement any athleisure outfit and are a fun way to inspire athletic competition between a group of friends. Here are a few ways you can patch some of their security shortcomings:
When you first purchase any new device, fitness trackers included, your first step should always be to reset the factory password. Cybercriminals know that many people often skip this step, making it easy for them to walk right into new accounts. If you have a hard time remembering your passwords, consider entrusting them to a password manager to remember them for you. McAfee True Key makes it so that you only have to remember one master password to unlock the rest, and it’s protected by one of the strongest encryption algorithms available.
This is a tip you should consider for all your social media accounts. When you post about your life online, you actually divulge a lot of personal details that are helpful to cybercriminals. In the case of fitness trackers and apps, sharing the times of day when you go to the gym, are at the local track, or are on a bike path may give a criminal an idea of windows during the day when your home is empty. It’s unsettling to think that strangers can track your whereabouts, so it’s best to keep those details exclusive to people you personally know and trust.
In the case of fitness trackers and apps, a savvy cybercriminal may be able take an educated guess at your address, with which they can do a myriad of nefarious activities. Some running and fitness apps may be able to still create maps of your running routes but erase street names and other landmarks to make it more private. But when in doubt, turn off geolocation.
Fitness trackers are a fun way to stir up some friendly competition, keep connected with your fit friends, and motivate yourself to exercise and maintain healthy habits. While you’re shopping for a new device or when evaluating your current tracker, keep these tips in mind to enjoy this technology to its fullest.
