The U.S. Federal Bureau of Investigation disclosed that it infiltrated the BlackCat ransomware group, a Russia-based criminal organization also known as ALPHV. The FBI seized BlackCat's darknet website and released a decryption tool that hundreds of victim companies can use to recover systems encrypted by BlackCat ransomware. BlackCat briefly regained control of its darknet site in response to a message promising higher affiliate commissions of 90% and removing restrictions on targeting certain organizations like hospitals or nuclear power plants.
