Attack summary

Severity: high — Data has been published (not merely threatened), and the victim is a major publicly listed global jewelry retailer with a large customer loyalty/membership base, making exposure of customer PII and corporate data significant; no explicit confirmation of regulated medical or government data, so critical is not warranted.

The Vendetta ransomware group claims to have exfiltrated data from Chow Tai Fook and has published it (disclosed status: data_published), referencing internal content consistent with company marketing and operations; no ransom amount or data volume was stated in the post.

Disclosure context

About Vendetta

Vendetta is a relatively minor ransomware group that emerged in February 2023, appearing to be financially motivated based on their operational patterns. The group's origin and affiliations remain largely unknown due to limited public reporting, though their small scale of operations suggests they likely operate as an independent entity rather than a major ransomware-as-a-service operation. Details regarding Vendetta's specific attack methodology, initial access vectors, and technical capabilities have not been extensively documented by major security firms or government agencies, indicating either highly targeted operations or limited visibility into their activities. With only three known victims since their emergence, Vendetta has not conducted any widely reported major campaigns or attracted significant law enforcement attention, distinguishing them from more prominent ransomware groups that typically generate extensive threat intelligence reporting. The group's current operational status remains unclear due to the limited public documentation surrounding their activities, though the small number of attributed victims suggests either highly selective targeting or limited operational capacity. The group has been linked to 3 public disclosures across our corpus. First observed on a leak site on February 12, 2023; most recent post February 27, 2023. The operation is currently inactive.

If your organisation is affected

A listing by Vendetta means Chowtaifook 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.
  • Monitor for the data appearing on Vendetta'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.
