New ransomware attack targets key IT vendor Brian Fung, CNN Business Share This (CNN) — US cyber officials are tracking a major new ransomware attack by the same group that hit meat supplier JBS Foods this spring. This time, the REvil malware hit a wide range of IT management companies and compromised hundreds of their corporate clients. The cybercriminal gang, which is believed to operate out of Eastern Europe or Russia, targeted a key software vendor known as Kaseya, whose products are widely used by IT management companies, cybersecurity experts said. On Saturday, President Joe Biden said that the US government is not certain who is behind the attack, but he has directed federal agencies to assist in the response.
