Introduction
Tesorion describes Lorenz as a ransomware with design and implementation flaws, leading to impossible decryption with tools provided by the attackers. A free decryptor for 2021 versions was made available via the NoMoreRansom initiative. A new version of the malware was discovered in March 2022, for which again was provided a free decryptor, while the ransomware operators are not able to provide tools to decrypt affected files.
