Ransomware attacks may have decreased slightly because of Russia’s invasion of Ukraine and associated sanctions. But ransomware is still a threat to organisations all around the world. Hackers continue to cause serious harm to global businesses.
Costa Rica declared a state of emergency in April after a major IT system outage caused by the Conti Ransomware attack. The ransomware attack began with the country’s Finance Ministry and quickly spread to other departments. This includes the National Weather Institute and the Ministry of Science, Technology, and Telecommunications.
Conti ransomware has been highly active recently, and it is most known for a $100 million attack on the Irish Healthcare System last year. Officials in the United Kingdom are concerned about a threat posed by Russian cybercriminals to the country’s National Health Service (NHS). Following the arrest of an accused pro-Putin cybercriminal in London, members of the cyber gang “Killnet” have threatened to attack all NHS ventilators. The US government is now offering a reward of up to $10 million for information leading to the identity and/or location of Conti ransomware gang.
The latest REvil ransomware samples were also evaluated by SecureWorks, confirming prior allegations that the ransomware group is back in some way. The Conti gang has denied being engaged in the current operation, according to a technical study released this week.
