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.
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.
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.
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.”
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’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.”
