The Week In Ransomware – March 19th 2021 – Highest Ransom Ever!
While the beginning of this week was fairly quiet, it definitely ended with a bang as news came out of the largest ransom demand yet.
It was revealed at the end of the week that computer maker Acer suffered a REvil ransomware attack where the threat actors are demanding a massive $50,000,000 ransom.
REvil also made this news this week with the addition of a new -smode argument that causes Windows to reboot into Safe Mode with Networking to perform the encryption. REvil’s ‘Unknown’ also conducted an interview with TheRecord.
Finally, we saw an FBI warning about PYSA and new variants of ransomware families released.
