It has been quite the week when it comes to ransomware, with ransoms being paid, ransoms being taken back, and a ransomware gang shutting down.
This week's biggest news was the FBI announcing that they were able to recover the majority of the $4.4 million ransom payment paid by Colonial Pipeline. It is not entirely clear how they obtained the private key for the cryptocurrency wallet, but it is believed DarkSide stored it on a seized server.
We also learned that JBS paid $11 million to the REvil ransomware operation to retrieve a decryptor and prevent stolen files from being leaked.
In a bit of good news, the Avaddon ransomware operation shut down and released the decryption keys of close to 3,000 victims to BleepingComputer. Using these, cybersecurity firm Emsisoft was able to release a free decryptor.
Finally, news broke this week that memory maker ADATA and food services supplier Edward Don suffered ransomware attacks.
