Fake Lawsuit Threat Exposes Privnote Phishing Sites

By BrianKrebs

A cybercrook who has been setting up websites that mimic the self-destructing message service privnote.com accidentally exposed the breadth of their operations recently when they threatened to sue a software company. The disclosure revealed a profitable network of phishing sites that behave and look like the real Privnote, except that any messages containing cryptocurrency addresses will be automatically altered to include a different payment address controlled by the scammers.

The real Privnote, at privnote.com.

Launched in 2008, privnote.com employs technology that encrypts each message so that even Privnote itself cannot read its contents. And it doesn’t send or receive messages. Creating a message merely generates a link. When that link is clicked or visited, the service warns that the message will be gone forever after it is read.

Privnote’s ease-of-use and popularity among cryptocurrency enthusiasts has made it a perennial target of phishers, who erect Privnote clones that function more or less as advertised but also quietly inject their own cryptocurrency payment addresses when a note is created that contains crypto wallets.

Last month, a new user on GitHub named fory66399 lodged a complaint on the “issues” page for MetaMask, a software cryptocurrency wallet used to interact with the Ethereum blockchain. Fory66399 insisted that their website — privnote[.]co — was being wrongly flagged by MetaMask’s “eth-phishing-detect” list as malicious.

“We filed a lawsuit with a lawyer for dishonestly adding a site to the block list, damaging reputation, as well as ignoring the moderation department and ignoring answers!” fory66399 threatened. “Provide evidence or I will demand compensation!”

MetaMask’s lead product manager Taylor Monahan replied by posting several screenshots of privnote[.]co showing the site did indeed swap out any cryptocurrency addresses.

After being told where they could send a copy of their lawsuit, Fory66399 appeared to become flustered, and proceeded to mention a number of other interesting domain names:

You sent me screenshots from some other site! It’s red!!!!
The tornote.io website has a different color altogether
The privatenote,io website also has a different color! What’s wrong?????

A search at DomainTools.com for privatenote[.]io shows it has been registered to two names over as many years, including Andrey Sokol from Moscow and Alexandr Ermakov from Kiev. There is no indication these are the real names of the phishers, but the names are useful in pointing to other sites targeting Privnote since 2020.

DomainTools says other domains registered to Alexandr Ermakov include pirvnota[.]com, privatemessage[.]net, privatenote[.]io, and tornote[.]io.

The registration records for pirvnota[.]com at one point were updated from Andrey Sokol to “BPW” as the registrant organization, and “Tambov district” in the registrant state/province field. Searching DomainTools for domains that include both of these terms reveals pirwnote[.]com.

Other Privnote phishing domains that also phoned home to the same Internet address as pirwnote[.]com include privnode[.]com, privnate[.]com, and prevnóte[.]com. Pirwnote[.]com is currently selling security cameras made by the Chinese manufacturer Hikvision, via an Internet address based in Hong Kong.

It appears someone has gone to great lengths to make tornote[.]io seem like a legitimate website. For example, this account at Medium has authored more than a dozen blog posts in the past year singing the praises of Tornote as a secure, self-destructing messaging service. However, testing shows tornote[.]io will also replace any cryptocurrency addresses in messages with their own payment address.

These malicious note sites attract visitors by gaming search engine results to make the phishing domains appear prominently in search results for “privnote.” A search in Google for “privnote” currently returns tornote[.]io as the fifth result. Like other phishing sites tied to this network, Tornote will use the same cryptocurrency addresses for roughly 5 days, and then rotate in new payment addresses.

Tornote changed the cryptocurrency address entered into a test note to this address controlled by the phishers.

Throughout 2023, Tornote was hosted with the Russian provider DDoS-Guard, at the Internet address 186.2.163[.]216. A review of the passive DNS records tied to this address shows that apart from subdomains dedicated to tornote[.]io, the main other domain at this address was hkleaks[.]ml.

In August 2019, a slew of websites and social media channels dubbed “HKLEAKS” began doxing the identities and personal information of pro-democracy activists in Hong Kong. According to a report (PDF) from Citizen Lab, hkleaks[.]ml was the second domain that appeared as the perpetrators began to expand the list of those doxed.

HKleaks, as indexed by The Wayback Machine.

DomainTools shows there are more than 1,000 other domains whose registration records include the organization name “BPW” and “Tambov District” as the location. Virtually all of those domains were registered through one of two registrars — Hong Kong-based Nicenic and Singapore-based WebCC — and almost all appear to be phishing or pill-spam related.

Among those is rustraitor[.]info, a website erected after Russia invaded Ukraine in early 2022 that doxed Russians perceived to have helped the Ukrainian cause.

In keeping with the overall theme, these phishing domains appear focused on stealing usernames and passwords to some of the cybercrime underground’s busiest shops, including Brian’s Club. What do all the phished sites have in common? They all accept payment via virtual currencies.

It appears MetaMask’s Monahan made the correct decision in forcing these phishers to tip their hand: Among the websites at that DDoS-Guard address are multiple MetaMask phishing domains, including metarrnask[.]com, meternask[.]com, and rnetamask[.]com.

How profitable are these private note phishing sites? Reviewing the four malicious cryptocurrency payment addresses that the attackers swapped into notes passed through privnote[.]co (as pictured in Monahan’s screenshot above) shows that between March 15 and March 19, 2024, those address raked in and transferred out nearly $18,000 in cryptocurrencies. And that’s just one of their phishing websites.

From Cybercrime Saul Goodman to the Russian GRU

By BrianKrebs

In 2021, the exclusive Russian cybercrime forum Mazafaka was hacked. The leaked user database shows one of the forum’s founders was an attorney who advised Russia’s top hackers on the legal risks of their work, and what to do if they got caught. A review of this user’s hacker identities shows that during his time on the forums he served as an officer in the special forces of the GRU, the foreign military intelligence agency of the Russian Federation.

Launched in 2001 under the tagline “Network terrorism,” Mazafaka would evolve into one of the most guarded Russian-language cybercrime communities. The forum’s member roster included a Who’s Who of top Russian cybercriminals, and it featured sub-forums for a wide range of cybercrime specialities, including malware, spam, coding and identity theft.

One representation of the leaked Mazafaka database.

In almost any database leak, the first accounts listed are usually the administrators and early core members. But the Mazafaka user information posted online was not a database file per se, and it was clearly edited, redacted and restructured by whoever released it. As a result, it can be difficult to tell which members are the earliest users.

The original Mazafaka is known to have been launched by a hacker using the nickname “Stalker.” However, the lowest numbered (non-admin) user ID in the Mazafaka database belongs to another individual who used the handle “Djamix,” and the email address djamix@mazafaka[.]ru.

From the forum’s inception until around 2008, Djamix was one of its most active and eloquent contributors. Djamix told forum members he was a lawyer, and nearly all of his posts included legal analyses of various public cases involving hackers arrested and charged with cybercrimes in Russia and abroad.

“Hiding with purely technical parameters will not help in a serious matter,” Djamix advised Maza members in September 2007. “In order to ESCAPE the law, you need to KNOW the law. This is the most important thing. Technical capabilities cannot overcome intelligence and cunning.”

Stalker himself credited Djamix with keeping Mazafaka online for so many years. In a retrospective post published to Livejournal in 2014 titled, “Mazafaka, from conception to the present day,” Stalker said Djamix had become a core member of the community.

“This guy is everywhere,” Stalker said of Djamix. “There’s not a thing on [Mazafaka] that he doesn’t take part in. For me, he is a stimulus-irritant and thanks to him, Maza is still alive. Our rallying force!”

Djamix told other forum denizens he was a licensed attorney who could be hired for remote or in-person consultations, and his posts on Mazafaka and other Russian boards show several hackers facing legal jeopardy likely took him up on this offer.

“I have the right to represent your interests in court,” Djamix said on the Russian-language cybercrime forum Verified in Jan. 2011. “Remotely (in the form of constant support and consultations), or in person – this is discussed separately. As well as the cost of my services.”

WHO IS DJAMIX?

A search on djamix@mazafaka[.]ru at DomainTools.com reveals this address has been used to register at least 10 domain names since 2008. Those include several websites about life in and around Sochi, Russia, the site of the 2014 Winter Olympics, as well as a nearby coastal town called Adler. All of those sites say they were registered to an Aleksei Safronov from Sochi who also lists Adler as a hometown.

The breach tracking service Constella Intelligence finds that the phone number associated with those domains — +7.9676442212 — is tied to a Facebook account for an Aleksei Valerievich Safronov from Sochi. Mr. Safronov’s Facebook profile, which was last updated in October 2022, says his ICQ instant messenger number is 53765. This is the same ICQ number assigned to Djamix in the Mazafaka user database.

The Facebook account for Aleksey Safronov.

A “Djamix” account on the forum privetsochi[.]ru (“Hello Sochi”) says this user was born Oct. 2, 1970, and that his website is uposter[.]ru. This Russian language news site’s tagline is, “We Create Communication,” and it focuses heavily on news about Sochi, Adler, Russia and the war in Ukraine, with a strong pro-Kremlin bent.

Safronov’s Facebook profile also gives his Skype username as “Djamixadler,” and it includes dozens of photos of him dressed in military fatigues along with a regiment of soldiers deploying in fairly remote areas of Russia. Some of those photos date back to 2008.

In several of the images, we can see a patch on the arm of Safronov’s jacket that bears the logo of the Spetsnaz GRU, a special forces unit of the Russian military. According to a 2020 report from the Congressional Research Service, the GRU operates both as an intelligence agency — collecting human, cyber, and signals intelligence — and as a military organization responsible for battlefield reconnaissance and the operation of Russia’s Spetsnaz military commando units.

Mr. Safronov posted this image of himself on Facebook in 2016. The insignia of the GRU can be seen on his sleeve.

“In recent years, reports have linked the GRU to some of Russia’s most aggressive and public intelligence operations,” the CRS report explains. “Reportedly, the GRU played a key role in Russia’s occupation of Ukraine’s Crimea region and invasion of eastern Ukraine, the attempted assassination of former Russian intelligence officer Sergei Skripal in the United Kingdom, interference in the 2016 U.S. presidential elections, disinformation and propaganda operations, and some of the world’s most damaging cyberattacks.”

According to the Russia-focused investigative news outlet Meduza, in 2014 the Russian Defense Ministry created its “information-operation troops” for action in “cyber-confrontations with potential adversaries.”

“Later, sources in the Defense Ministry explained that these new troops were meant to ‘disrupt the potential adversary’s information networks,'” Meduza reported in 2018. “Recruiters reportedly went looking for ‘hackers who have had problems with the law.'”

Mr. Safronov did not respond to multiple requests for comment. A 2018 treatise written by Aleksei Valerievich Safronov titled “One Hundred Years of GRU Military Intelligence” explains the significance of the bat in the seal of the GRU.

“One way or another, the bat is an emblem that unites all active and retired intelligence officers; it is a symbol of unity and exclusivity,” Safronov wrote. “And, in general, it doesn’t matter who we’re talking about – a secret GRU agent somewhere in the army or a sniper in any of the special forces brigades. They all did and are doing one very important and responsible thing.”

It’s unclear what role Mr. Safronov plays or played in the GRU, but it seems likely the military intelligence agency would have exploited his considerable technical skills, knowledge and connections on the Russian cybercrime forums.

Searching on Safronov’s domain uposter[.]ru in Constella Intelligence reveals that this domain was used in 2022 to register an account at a popular Spanish-language discussion forum dedicated to helping applicants prepare for a career in the Guardia Civil, one of Spain’s two national police forces. Pivoting on that Russian IP in Constella shows three other accounts were created at the same Spanish user forum around the same date.

Mark Rasch is a former cybercrime prosecutor for the U.S. Department of Justice who now serves as chief legal officer for the New York cybersecurity firm Unit 221B. Rasch said there has always been a close relationship between the GRU and the Russian hacker community, noting that in the early 2000s the GRU was soliciting hackers with the skills necessary to hack US banks in order to procure funds to help finance Russia’s war in Chechnya.

“The guy is heavily hooked into the Russian cyber community, and that’s useful for intelligence services,” Rasch said. “He could have been infiltrating the community to monitor it for the GRU. Or he could just be a guy wearing a military uniform.”

Cisco Talos Supports Ukraine Through Empathy

By Mary Kate Schmermund

Cisco Talos has a long-standing relationship with Ukraine, so when Russia invaded the country earlier this year, things hit close to home. Cisco Talos leaders rallied together to provide cybersecurity threat hunting to vital infrastructure, humanitarian support and goods and services to employees and their families in the region.

Ashlee Benge, Amy Henderson and Sammi Seaman spearheaded initiatives to support and sustain Ukrainian employees and threat hunters working around-the-clock to prevent cyberattacks and remember the human element. Even in the midst of crisis, they’ve facilitated open communication, emphasized mental health and cultivated connection.

Cisco Talos’ Relationship With Ukraine

Given Ukraine’s unique position on the front lines of cyberwarfare, Cisco Talos has had a very close partnership with Ukraine. The threat intelligence team has worked with several partners in the country from a cyber threat perspective. That long standing connection is part of why Russia’s invasion of Ukraine has been felt so deeply. “Some Ukrainian team members evacuated before the invasion, others did not,” said Amy Henderson, head of strategic planning & communications. “Our teams of threat hunters have been around-the-clock hunting in the data since the invasion. They’re stopping attacks from happening.”

Cisco Talos set up Cisco Secure Endpoint on about thirty partners’ organizations and extended the offering to critical infrastructure organizations in Ukraine such as hospitals, directly monitoring Cisco Secure Endpoint, “because their people are busy doing other things right now. They can’t sit at a screen,” Henderson said.

Leading With Empathy and Open Communication

Lead of Strategic Business Intelligence Ashlee Benge directs the Ukraine Threat Hunting Task Unit which requires empathy, compassion and an awareness of the needs of forty-five threat hunters. Veteran threat hunters with decades of experience have volunteered to contribute to the team while other members of Cisco Talos have also volunteered their skill sets to the work. Benge values the distinct contributions of her team members and describes them as, “quite brilliant and very good at their jobs. Talos does a really good job of hiring good people, and so the worst thing that I could do is get in their way.” Getting in their way looks different for different team members which is why Benge has established trainings and consistent ways to evaluate that the needs of her team are being met.

The nature of such a demanding, on-going situation coupled with the team’s dedication can lead employees to work themselves into the ground. To combat this, leaders maintain weekly check-ins that include asking employees how they’re taking care of themselves and checking for signs of burnout. “When you have rest you’re at peak performance and can problem solve. But when you start burning out and get to be irritable and snappy, you’re not able to problem solve. Just step back. You’ll be in a much better head space,” Henderson advises.

Stepping back has meant rotating projects to level out activity levels and urgency. Leaders have also stepped in to ensure employees take time off and that when they’re away, they’re fully away. “When you’re in such a high intensity environment it takes two to three days just to come off of that. If you’re only taking a day here or day there, you’re not even scratching the surface of coming down. So I’ll suggest maybe you need to take a week and completely recharge,” Henderson says.

Supporting The Human Element

Team Lead of Employee Experience Sammi Seaman was heartened by Cisco’s support of Ukrainian employees including helping employees and their families out of cities and into new housing. The humanitarian focus led Seaman to ask “How else can we help? Our colleagues have had to leave their homes and they’re still trying to do work. How do I get them necessities like medicine and shampoo?”

Seaman’s empathy and collaboration within her team and with Cisco Talos leadership led to determining the highest needs including more stable internet and navigating the transport of goods directly to employees and their families through freight mail. Seaman worked with her team to ensure necessary items like medical kits could get directly to people who needed them as quickly as possible. There are also pages available coordinating housing, transportation and other forms of support.

“It’s been interesting to think about people needing medicine for various reasons and that I’m also buying Legos and castles so that the children who have been displaced have toys and things that bring them joy and allow them to be kids in this situation,” Seaman said.

As Seaman prepared more boxes to ship, an employee shared a photograph of his daughter with some of the things Seaman had sent. “I just started crying. It was such a relief.” A relief she wanted to share, leaving the boxes for a moment to connect with other team members around the positive impact of their hard work.

“Despite all of these things that are happening around us that are horrific and awful and things that shouldn’t be happening, there are still things that we can celebrate. We’re still humans who have feelings, relationships, milestones and holidays.” – Sammi Seaman

Remembering children also became important during spring holidays. Through asking employees if they celebrated Easter and if they’d like Easter baskets, she learned that many employees celebrated traditional Orthodox Ukrainian Easter and would appreciate the baskets.

Seaman’s colleague researched what people in Ukraine typically put in their Easter baskets and together they made the baskets, boxed them up and shipped them. “The baskets weren’t a necessity but were nice to remind people that despite all of these things that are happening around us that are horrific and awful and things that shouldn’t be happening, there are still things that we can celebrate. We’re still humans who have feelings, relationships, milestones and holidays.”

Mental Health and Self-Care Matter

Outside of work, Benge competes as an Olympic weightlifter. After months of training, her first national level meet was scheduled to happen early into the war in Ukraine. She considered withdrawing given the 24/7 nature of Cisco Talos’ response. However, “only because of the support of those around me,” Benge decided to compete—while working from her phone in the warm up room between lifts. The physical movement allows Benge to manage her mental health and stress while modeling self-care for the team: “If I can’t be my own best self, then the people around me can hardly be expected to do the same.”

Self-care and mental health are so important to the team that Henderson and Benge recently joined their colleagues, Matt Olney, the director of threat intelligence and interdiction, and Strategic Communications Leader Mitch Neff on a Cisco Secure podcast about mental health. The conversation illuminated the importance of reaching out for help, utilizing support systems such as those provided by Cisco and talking to someone including a therapist.

“Using those types of resources is a valuable thing, particularly when managing very high levels of stress and anxiety that come with cybersecurity. No matter what kind of support it is that we need, it’s important to take that time and recognize that it’s valuable to invest in your own mental health,” Benge stated.

Seaman shared that because it can be hard to ask for help or delegate, when she does, she gives herself a pat on the back. She advises that especially in crisis situations it’s important to remember that while things need to get done, it’s not entirely on you to get those things done. “The leadership at Cisco Talos has really emphasized that you’re not alone. The employee assistance program has been a great resource and I’ve got a therapist that I talk to about these things and make sure that I’m taking care of myself so that I can continue to take care of others.”

The team’s bond and purpose run deep. We care deeply about everyone that we work with. It’s okay to not be on at all times. It’s okay to feel sad and it’s okay to feel anxious. One of the things that I’ve loved about working with Cisco Talos, especially during these more difficult things, is that everybody’s got your back and they make it a safe space to share those feelings. I truly feel like the people I work with are like my family. We’re curated an environment where we can all talk about what we’re going through.”

Costa Rica May Be Pawn in Conti Ransomware Group’s Bid to Rebrand, Evade Sanctions

By BrianKrebs

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.

THE NAME GAME DISTRACTION

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.”

Russia to Rent Tech-Savvy Prisoners to Corporate IT?

Faced with a brain drain of smart people fleeing the country following its invasion of Ukraine, the Russian Federation is floating a new strategy to address a worsening shortage of qualified information technology experts: Forcing tech-savvy people within the nation’s prison population to perform low-cost IT work for domestic companies.

Multiple Russian news outlets published stories on April 27 saying the Russian Federal Penitentiary Service had announced a plan to recruit IT specialists from Russian prisons to work remotely for domestic commercial companies.

Russians sentenced to forced labor will serve out their time at one of many correctional centers across dozens of Russian regions, usually at the center that is closest to their hometown. Alexander Khabarov, deputy head of Russia’s penitentiary service, said his agency had received proposals from businessmen in different regions to involve IT specialists serving sentences in correctional centers to work remotely for commercial companies.

Khabarov told Russian media outlets that under the proposal people with IT skills at these facilities would labor only in IT-related roles, but would not be limited to working with companies in their own region.

“We are approached with this initiative in a number of territories, in a number of subjects by entrepreneurs who work in this area,” Khabarov told Russian state media organization TASS. “We are only at the initial stage. If this is in demand, and this is most likely in demand, we think that we will not force specialists in this field to work in some other industries.”

According to Russian media site Lenta.ru, since March 21 nearly 95,000 vacancies in IT have remained unfilled in Russia. Lenta says the number unfilled job slots actually shrank 25 percent from the previous month, officially because “many Russian companies are currently reviewing their plans and budgets, and some projects have been postponed.” The story fails to even mention the recent economic sanctions that are currently affecting many Russian companies thanks to Russia’s invasion of Ukraine in late February.

The Russian Association for Electronic Communications (RAEC) estimated recently that between 70,000 and 100,000 people will leave Russia as part of the second wave of emigration of IT specialists from Russia. “The study also notes that the number of IT people who want to leave Russia is growing. Experts consider the USA, Germany, Georgia, Cyprus and Canada to be the most attractive countries for moving,” Lenta reported of the RAEC survey.

It’s not clear how many “IT specialists” are currently serving prison time in Russia, or precisely what that might mean in terms of an inmate’s IT skills and knowledge. According to the BBC, about half of the world’s prison population is held in the United States, Russia or China. The BBC says Russia currently houses nearly 875,000 inmates, or about 615 inmates for every 100,000 citizens. The United States has an even higher incarceration rate (737/100,000), but also a far larger total prison population of nearly 2.2 million.

Sergei Boyarsky, deputy chairman of the Russian Duma’s Committee on Information Policy, said the idea was worth pursuing if indeed there are a significant number of IT specialists who are already incarcerated in Russia.

“I know that we have a need in general for IT specialists, this is a growing market,” said Boyarsky, who was among the Russian leaders sanctioned by the United States Treasury on Marc. 24, 2022 in response to the Russian invasion of Ukraine. Boyarsky is head of the St. Petersburg branch of United Russia, a strongly pro-Putin political party that holds more than 70 percent of the seats in the Russian State Duma.

“Since they still work there, it would probably be right to give people with a profession that allows them to work remotely not to lose their qualifications,” Boyarsky was quoted as saying of potentially qualified inmates. “At a minimum, this proposal is worth attention and discussion if there are a lot of such specialists.”

According to Russia’s penitentiary service, the average salary of those sentenced to forced labor is about 20,000 rubles per month, or approximately USD $281. Russian news outlet RBC reports that businesses started using prison labor after the possibility of creating correctional centers in organizations appeared in 2020. RBC notes that Russia now has 117 such centers across 76 Russian regions.
