LeChiffre is a relatively obscure ransomware group that emerged in March 2016 with apparent financial motivations, though limited public documentation exists about their operations. The group's origin and affiliations remain largely unknown, with no clear indicators of state sponsorship or connections to other established ransomware operations, suggesting they likely operated as an independent entity rather than part of a larger ransomware-as-a-service ecosystem. Based on available intelligence, the group appears to have employed standard ransomware deployment tactics, though specific details about their initial access vectors, encryption methods, or use of data exfiltration techniques have not been extensively documented by major security researchers or law enforcement agencies. LeChiffre's most notable characteristic appears to be their targeting of U.S. government facilities, with at least one documented victim in this sector, though the specific details of these attacks and any associated ransom demands have not been publicly disclosed by CISA, FBI, or other authoritative sources. The group's current operational status is unclear, as there have been no recent public reports of LeChiffre activity since their initial emergence, suggesting they may have ceased operations, rebranded, or simply maintained a very low profile in the threat landscape. The group has been linked to 1 public disclosures across our corpus. First observed on a leak site on March 1, 2016. The operation is currently inactive.

If your organisation is affected
A listing by lechiffre means Manlius appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.
- Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
- Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
- Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
- Report the incident to your national CERT, CISA (United States), as required for your jurisdiction.
- Monitor for the data appearing on lechiffre's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
