Avast has just released a decryption tool that will help AtomSilo and LockFile ransomware victims recover some of their files for free without having to pay a ransom.
Avast released another decryption tool earlier today to help Babuk ransomware victims recover their files for free.

As the Czech cybersecurity software firm explained, this decryptor may not be able to decrypt files with unknown, proprietary, or with no format at all.
"During the decryption process, the Avast AtomSilo decryptor relies on a known file format in order to verify that the file was successfully decrypted. For that reason, some files may not be decrypted," Avast's Threat Intelligence Team said.

The decryptor works for both ransomware strains because they are very similar, even though the groups deploying them on victims' networks use different attack tactics.
