Attack summary

Severity: medium — Data published status confirms disclosure, but no proof files are advertised in the post. The firm handles sensitive financial and tax data for international clients, which elevates concern, but the lack of detail on exfiltration scope and no demonstrated proof files prevents a higher rating.

The Lv ransomware group claims to have compromised interfides and published data. The post does not specify whether data was exfiltrated, encrypted, or both, nor does it detail what information was accessed.

Disclosure context

About Lv

Lv is a financially motivated ransomware group that emerged in November 2021, operating with relatively low visibility compared to major ransomware families but maintaining consistent activity across multiple regions and sectors. The group's country of origin and specific affiliations remain undocumented in public threat intelligence reporting, though their targeting patterns suggest they operate independently rather than as part of a larger ransomware-as-a-service ecosystem. Limited public documentation exists regarding Lv's specific attack methodology, initial access vectors, or technical capabilities, though their successful compromise of 115 documented victims across diverse sectors indicates they employ conventional ransomware deployment techniques. The group has demonstrated a preference for targeting critical infrastructure and business services, with notable geographic focus on Russia, France, Malaysia, the United States, and the Netherlands, spanning sectors including energy, telecommunications, business services, media, and non-profit organizations. Current intelligence suggests Lv remains active as of recent reporting, though the group maintains a lower profile than prominent ransomware families and has not been subject to major law enforcement disruption operations. The group has been linked to 115 public disclosures across our corpus. First observed on a leak site on November 22, 2021; most recent post March 13, 2024. The operation is currently inactive.

If your organisation is affected

A listing by Lv means interfides.de 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, CERT-Bund (Germany), as required for your jurisdiction.
  • Monitor for the data appearing on Lv'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.
