Resecurity Reports ExfilSquad Claims 13 Victims and Shares Data via Torrents

Summary
Resecurity reports that ExfilSquad claimed 13 organizations as victims and posted torrents said to contain stolen data. Its analysis found more than 50 later seeds and early activity from hosts in China and Russia, without linking those hosts to the group.
Key points
- Resecurity describes ExfilSquad as a financially motivated extortion group that threatens to publish data rather than typically using ransomware or destructive malware.
- The group claimed 13 organizations as victims and posted multiple torrents on August 7, 2026. The posts are evidence of the group’s claims, not independent confirmation of every alleged compromise.
- The report says the claims involve data from organizations across sectors, including customer, employee, student, and resident information.
- Resecurity identifies CRM, case-management, and consumer-facing portals as notable targets; an ExfilSquad representative said members targeted inadequately protected Microsoft Power Pages data tables.
- Resecurity observed more than 50 torrent seeds over time. Hosts in China and Russia were among the early active participants, but the report says they are unlikely to be directly associated with the group.
- ExfilSquad’s claim about Zenith Bank, alleging theft of around 90 million records, had been removed from its leak site by August 7. The bank had acknowledged an investigation into a possible cybersecurity incident; the outcome was unknown.
- Resecurity recommends ongoing vulnerability assessments and stronger access controls for CRM systems, employee portals, and consumer-facing portals that store sensitive data.
