Costa Rica’s nationwide well being service was hacked someday earlier this morning by a Russian ransomware group often known as Hive. The intrusion comes simply weeks after Costa Rican President Rodrigo Chaves declared a state of emergency in response to an information ransom assault from a distinct Russian ransomware gang — Conti. Ransomware specialists say there’s good purpose to imagine the identical cybercriminals are behind each assaults, and that Hive has been serving to Conti rebrand and evade worldwide sanctions concentrating on extortion payouts to cybercriminals working in Russia.
The Costa Rican publication CRprensa.com reviews that affected programs on the Costa Rican Social Safety Fund (CCSS) have been taken offline on the morning of Could 31, however that the extent of the breach was nonetheless unclear. The CCSS is answerable for Costa Rica’s public well being sector, and employee and employer contributions are mandated by legislation.

A hand-written discover posted outdoors a public well being clinic at this time in Costa Rica warned of system outages on account of a cyberattack on the nation’s healthcare programs. The message reads: “Expensive Customers: We want to inform you that due an issue associated to the knowledge programs of the establishment, we’re unable to expend any medication prescriptions at this time till additional discover. Thanks to your understanding- The pharmacy.”
Esteban Jimenez, founding father of the Costa Rican cybersecurity consultancy ATTI Cyber, informed KrebsOnSecurity the CCSS suffered a cyber assault that compromised the Distinctive Digital Medical File (EDUS) and the Nationwide Prescriptions System for the general public pharmacies, and in consequence medical facilities have turned to paper types and guide contingencies.
“Many smaller well being facilities positioned in rural areas have been compelled to shut on account of not having the required tools or communication with their respective central well being areas and the Nationwide Retirement Fund (IVM) was fully blocked,” Jimenez stated. “Bearing in mind that salaries of round fifty thousand workers and deposits for retired residents have been due at this time, so now the funds are at risk.”
Jimenez stated the top of the CCSS has addressed the native media, confirming that the Hive ransomware was deployed on at the very least 30 out of 1,500 authorities servers, and that any estimation of time to restoration stays unknown. He added that many printers throughout the authorities company this morning started churning out copies of the Hive ransom notice.

“HIVE has not but launched their ransom payment however assaults are anticipated to comply with, different organizations try to get a maintain on the emergency declaration to acquire further funds to buy new items of infrastructure, enhance their backup construction amongst others,” Jimenez stated.
A duplicate of the ransom notice left behind by the intruders and subsequently uploaded to Virustotal.com signifies the CCSS intrusion was the work of Hive, which generally calls for fee for a digital key wanted to unlock recordsdata and servers compromised by the group’s ransomware.

On Could 8, President Chaves used his first day in workplace to declare a nationwide state of emergency after the Conti ransomware group threatened to publish gigabytes of delicate information stolen from Costa Rica’s Ministry of Finance and different authorities businesses. Conti initially demanded $10 million, and later doubled the quantity when Costa Rica refused to pay. On Could 20, Conti leaked greater than 670 gigabytes of knowledge taken from Costa Rican authorities servers.
As CyberScoop reported on Could 17, Chaves informed native media he believed that collaborators inside Costa Rica have been serving to Conti extort the federal government. Chaves provided no data to assist this declare, however the timeline of Conti’s descent on Costa Rica is price analyzing.
Most of Conti’s public communications concerning the Costa Rica assault have very clearly assigned credit score for the intrusion to a person or group calling itself “unc1756.” In March 2022, a brand new person by the identical title registered on the Russian language crime discussion board Exploit.
A message Conti posted to its darkish net weblog on Could 20.
On the night of April 18, Costa Rica’s Ministry of Finance disclosed the Conti intrusion via Twitter. Earlier that very same day, the person unc1756 posted a assist wished advert on Exploit saying they have been trying to purchase entry to “particular networks” in Costa Rica.
“By particular networks I imply one thing like Haciendas,” unc1756 wrote on Exploit. Costa Rica’s Ministry of Finance is thought in Spanish because the “Ministerio Hacienda de Costa Rica.” Unc1756 stated they’d pay $USD 500 or extra for such entry, and would work solely with Russian-speaking individuals.
THE NAME GAME DISTRACTION
Consultants say there are clues to recommend Conti and Hive are working collectively of their assaults on Costa Rica, and that the intrusions are tied to a rebranding effort by Conti. Shortly after Russia invaded Ukraine on the finish of February, Conti declared its full assist, aligning itself instantly with Russia and in opposition to anybody who would stand in opposition to the motherland.
Conti’s threatening message this week concerning worldwide interference in Ukraine.
Conti shortly deleted the declaration from its web site, however the injury had already been completed, and any favor or esteem that Conti had earned among the many Ukrainian cybercriminal underground successfully evaporated in a single day.
Shortly thereafter, a Ukrainian safety skilled leaked many months price of inside chat data between Conti personnel as they plotted and executed assaults in opposition to a whole lot of sufferer organizations. These candid messages uncovered what it’s prefer to work for Conti, how they undermined the safety of their targets, in addition to how the group’s leaders strategized for the higher hand in ransom negotiations.
However Conti’s declaration of solidarity with the Kremlin additionally made it more and more ineffective as an instrument of monetary extortion. Based on cyber intelligence agency ADVIntel, Conti’s alliance with the Russian state quickly left it largely unable to obtain ransom funds as a result of sufferer firms are being suggested that paying a Conti ransom demand may imply violating U.S. financial sanctions on Russia.
“Conti as a model grew to become related to the Russian state — a state that’s presently present process excessive sanctions,” ADVIntel wrote in a prolonged evaluation (PDF). “Within the eyes of the state, every ransom fee going to Conti might have doubtlessly gone to a person beneath sanction, turning easy information extortion right into a violation of OFAC regulation and sanction insurance policies in opposition to Russia.”

ADVIntel says it first realized of Conti’s intrusion into Costa Rican authorities programs on April 14, and that it has seen inside Conti communications indicating that getting paid within the Costa Rica assault was not the aim.
Quite, ADVIntel argues, Conti was merely utilizing it as a strategy to seem publicly that it was nonetheless working because the world’s most profitable ransomware collective, when in actuality the core Conti management was busy dismantling the crime group and folding themselves and high associates into different ransomware teams which might be already on pleasant phrases with Conti.
“The one aim Conti had wished to satisfy with this remaining assault was to make use of the platform as a device of publicity, performing their very own demise and subsequent rebirth in probably the most believable approach it may have been conceived,” ADVIntel concluded.
ADVIntel says Conti’s leaders and core associates are dispersing to a number of Conti-loyal crime collectives that use both ransomware lockers or strictly have interaction in information theft for ransom, together with AlphV/BlackCat, AvosLocker, BlackByte, HelloKitty, Hive, and Karakurt.
Nonetheless, Hive seems to be maybe the most important beneficiary of any attrition from Conti: Twice over the previous week, each Conti and Hive and claimed accountability for hacking the identical firms. When the discrepancy was called out on Twitter, Hive up to date its web site to assert it was not affiliated with Conti.
Conti and Hive’s Costa Rican exploits mark the newest in a string of latest cyberattacks in opposition to authorities targets throughout Latin America. Across the similar time it hacked Costa Rica in April, Conti introduced it had hacked Peru’s Nationwide Directorate of Intelligence, threatening to publish delicate stolen information if the federal government didn’t pay a ransom.
However Conti and Hive usually are not alone in concentrating on Latin American victims of late. Based on information gathered from the sufferer shaming blogs maintained by a number of ransomware teams, over the previous 90 days ransom actors have hacked and sought to extort 15 authorities businesses in Brazil, 9 in Argentina, six in Colombia, 4 in Ecuador and three in Chile.
A latest report (PDF) by the Inter-American Growth Financial institution suggests many Latin American nations lack the technical experience or cybercrime legal guidelines to cope with at this time’s threats and menace actors.
“This research exhibits that the Latin American and Caribbean (LAC) area is just not sufficiently ready to deal with cyberattacks,” the IADB doc explains. “Solely 7 of the 32 nations studied have a crucial infrastructure safety plan, whereas 20 have established cybersecurity incident response groups, typically referred to as CERTs or CSIRTs. This limits their means to determine and reply to assaults.”
