Disclosure context

About ExfilSquad

ExfilSquad is a relatively nascent ransomware group first observed in July 2026 with a confirmed victim count of 14, operating with an apparent financial motivation consistent with contemporary cybercriminal ransomware operations. The group's country of origin and potential affiliations with known threat actor clusters or ransomware-as-a-service ecosystems have not yet been publicly attributed by CISA, FBI, Mandiant, or other reputable security research organizations, and details regarding their operational infrastructure remain limited in open-source reporting. Based on observed targeting patterns, ExfilSquad has demonstrated a preference for high-value sectors including Government and Defense, Technology, Financial Services, Education, and Transportation, with victim organizations concentrated primarily in the United States and Great Britain, and additional targeting observed in Sweden and Nigeria, suggesting a financially motivated group comfortable operating across multiple jurisdictions rather than one with a narrowly defined geopolitical focus. Given the group's recent emergence and relatively limited victim count, detailed technical indicators regarding their specific initial access vectors, tooling, encryption implementation, or use of double-extortion data leak sites have not been comprehensively documented in publicly available threat intelligence reporting at this time. As of the time of this profile, no significant law enforcement actions, disruptions, or confirmed rebranding activity associated with ExfilSquad have been publicly disclosed, and the group should be considered potentially active given the recency of their first observed activity. The group has been linked to 15 public disclosures across our corpus. First observed on a leak site on July 26, 2026. The operation is currently active.

If your organisation is affected

A listing by ExfilSquad means Zenith Bank Plc 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 ExfilSquad'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.
