What is Black Basta ransomware?
Black Basta ransomware seems to be a rebrand of an experienced operation i.e, Conti ransomware operation. It steals corporate data and documents before encrypting a company's devices and demands a wholesome amount to not leak data. It slowly leaks data for each victim to try and pressure them into paying a ransom.
How does Black Basta ransomware work?
According to BleepingComputer, the ransomware hacks into an existing Windows service and uses it to launch the ransomware decryptor executable. The ransomware then changed the wallpaper to display a message stating, "Your network is encrypted by the Black Basta group. Instructions in the file readme.txt" and reboot the computer into Safe Mode with Networking. Ransomware expert Michael Gillespie informed the portal Black Basta ransomware utilizes the ChaCha20 algorithm to encrypt files. Each folder on the encrypted device contains a readme.txt file that has information about the attack and a link and unique ID to log in to the negotiation chat session with the threat actors. They then demand a ransom and threaten to leak data if payment is not made in seven days, and promise to secure data after a ransom is paid.
Unfortunately, the encryption algorithm is secure and there is no way to recover files for free.
