The Department of Justice (DoJ) recently announced that the Federal Bureau of Investigation was able to gain access to the infrastructure of the ALPHV/BlackCat ransomware group, which allowed it to seize the websites used for communication, data leaks, and negotiations and obtain the decryption keys to help around 500 victims recover from attacks. The decryption tool developed by the FBI has saved around $68 million in ransom payments, according to the DoJ.

The FBI was able to obtain 946 public/private key pairs...
