Ransomware Week – May 13, 2022

While ransomware attacks slowed during Russia’s invasion of Ukraine and subsequent sanctions, the threat of malware continues to affect organizations around the world.

This can be seen with Costa Rica declaring a national emergency after suffering a massive computer systems outage caused by a Conti Ransomware attack in April.

These outages impact utilities, including requiring people to pay taxes in banks rather than online.

This statement comes shortly after the US government offered a $15 million reward for locating and identifying Conti ransomware members.

Secureworks also analyzed the new REvil ransomware samples, confirming previous reports that the ransomware gang has returned. With the threat actors having both the REvil source code and the Tor private keys, it’s clear that the operation somehow got back.

Other news this week includes a technical analysis from Black Basta with the Conti gang denying involvement in the new operation.
