Ransomware .VVX3i06B: HowToRecover.txt note demands Gmail contact

A security consultant is currently managing a ransomware incident for a client whose Windows server has been compromised by an unknown strain. The attack leaves files with the extension .VVX3i06B and drops a ransom note titled “HowToRecover.txt”, which directs victims to contact the attackers via a Gmail address. The case was posted in the Ransomware Help & Tech Support forum under the ID Ran.

The consultant is seeking assistance in identifying the ransomware variant, as the file extension and note format do not match any widely known family. The encrypted files are inaccessible, and the note demands payment in exchange for a decryption key. The attackers have provided only an email contact, with no other communication channels or payment portal visible.

This incident underscores the ongoing threat of targeted ransomware attacks against enterprise Windows environments. The lack of a known decryptor or public identification for this strain complicates recovery efforts. The consultant is advising the client to avoid paying the ransom, as there is no guarantee the attackers will provide a working decryption tool. Instead, the focus is on forensic analysis of the intrusion vector and exploring backup restoration options.

The post invites input from the security community, asking for any prior encounters with the . VVX3i06B extension or the HowToRecover.txt note. Early analysis suggests this could be a new or customized variant, possibly using a unique encryption algorithm or key generation process. The consultant plans to upload sample encrypted files and the ransom note for further examination by malware researchers.
