Disclosure context

About bqtlock

Based on available intelligence, bqtlock is a recently emerged ransomware group first observed in July 2025, with documented attacks against at least five victims and appears to be financially motivated. The group's origin and affiliations remain unclear due to limited public documentation from established threat intelligence sources, though their targeting pattern suggests possible operation from regions outside their primary victim countries. Attack methodologies and technical capabilities have not been extensively documented by major security firms, though the group appears to focus on opportunistic targeting across diverse sectors including technology, public sector, and educational institutions. The ransomware primarily targets organizations in the United States and United Arab Emirates, suggesting either specific regional interests or exploitation of common vulnerabilities in these markets. Due to the group's recent emergence and limited public reporting from authoritative sources like CISA, FBI, or established security researchers, detailed information about their specific tools, tactics, and procedures remains undocumented in open-source intelligence. The group appears to remain active as of their recent identification in mid-2025, though their operational scale and long-term persistence remain to be determined. The group has been linked to 5 public disclosures across our corpus. First observed on a leak site on July 31, 2025; most recent post October 11, 2025. The operation is currently inactive.

About the victim

AI dossier — public-source company profile

No verifiable company identity could be established. The victim name 'European Business Server Cluster' appears to be a generic placeholder. The leak post lists numerous domain names (bizoneo.com, bizosoft.eum, wandsoft.com, tourguides.ie, cleanrooms-ireland.ie, and 138+ others) but does not clearly attribute them to a single identifiable entity.

Attack summary

Severity: low — Listing of domains with no stated operational impact, no proof files advertised, and no confirmation of data exfiltration or encryption. The vague 'server cluster' framing and absence of specific breach details limit verifiability.

The bqtlock group claims to have compromised a server cluster hosting multiple domains. The post lists affected domain names but provides no details on whether data was exfiltrated, encrypted, or both, nor what types of data are at stake.
