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.

What does a ransomware group do?
Ransomware groups break into corporate networks, move data out and encrypt systems. If the ransom is not paid, they list the organization on a leak site and threaten to publish the data.
What should you do if your organization is listed on a leak site?
- Record the listing and any published sample files; do not visit the leak site from the corporate network.
- Isolate affected systems and preserve logs without deleting them.
- Determine which data left the organization; if personal data is involved, review notification obligations with your legal team.
- Make any decision about the ransom demand together with legal, management and incident response.
- Do not bring systems back online before the attacker’s entry point is closed.
