It has been relatively busy this week with new ransomware attacks unveiled, a bug bounty program introduced, and new tactics used by the threat actors to distribute their encryptors.
This week’s big news was the release of LockBit 3.0, which includes a new bug bounty reward program where the threat actors pay between $1,000 to $1 million for submitted bugs and new ways of enhancing their operation.
We also learned that a LockBit affiliate is distributing the ransomware through fake copyright infringement emails, Word docs are used to install AstraLocker directly, and the Black Basta gang is exploiting the PrintNightmare vulnerabilities.
Finally, we also learned about various attacks this week, including those on Macmillan, Fitzgibbon Hospital, Med. University of Innsbruck, and TB Kawashima. Threat actors also claimed to have attacked AMD, who are investigating the claims, and Walmart, who says the attack never occurred.
