B to B Visions Ransomware Claim by Qilin (Apr 2026)

Claim Summary

On April 23, 2026, the Qilin ransomware group added B to B Visions (www.btobvisions.com) to its dark web leak site. The threat actor claims to have compromised the business services firm, but has not disclosed any data samples, file listings, or proof of exfiltration. The data volume is listed as “Undisclosed,” and no specific attack date or ransom demand has been provided. This claim has not been independently verified by Yazoul Security.

Threat Actor Profile

Qilin (also tracked as Agenda, Gold Feather, and UNC3944) is an active ransomware-as-a-service (RaaS) operation first observed in mid-2022. The group has a known victim count of 1,617 organizations, indicating a high-volume, opportunistic targeting strategy. Their operational history includes attacks on healthcare, manufacturing, technology, and business services sectors.

Qilin’s technical toolkit is well-documented and includes:

• Mimikatz for credential dumping
• EDRSandBlast and PCHunter for endpoint detection and response (EDR) evasion
• PowerTool for privilege escalation and process manipulation
• Nmap and Nping for network reconnaissance
• EasyUpload.io and MEGA for data exfiltration

The group has demonstrated advanced capabilities, including propagation to VMware vCenter and ESXi hypervisors via custom PowerShell scripts (as noted in Trend Micro research). They also employ SMS phishing and SIM-swapping attacks to gain initial access, as documented by Google Cloud’s threat intelligence team.

Secureworks tracks this group as “Gold Feather” and notes a pattern of double extortion: encrypting systems while exfiltrating sensitive data to pressure victims into paying.

Alleged Data Exposure

According to the leak site entry, Qilin claims to have accessed B to B Visions’ systems but has not released any evidence of data exfiltration. The absence of sample files, file count, or data volume is unusual for Qilin, which typically provides proof-of-theft to increase credibility. This could indicate:

• The attack is in an early negotiation phase
• The group is bluffing to pressure the victim
• The data is still being processed for release

No specific data types (e.g., client contracts, financial records, employee PII) have been alleged.

Potential Impact

If the claim is valid, B to B Visions could face:

• Operational disruption from encrypted systems and potential downtime
• Reputational damage among business clients who rely on their services
• Regulatory scrutiny if client data (e.g., contracts, financial information) is compromised
• Financial losses from ransom demands, forensic investigations, and potential legal liabilities

As a business services provider, B to B Visions likely holds sensitive third-party data, making this a supply chain risk for their clients.

What to Watch For

• Leak site updates: Monitor Qilin’s portal for any data publication or sample releases
• Official confirmation: B to B Visions has not publicly acknowledged the incident. Any statement from the company should be treated as authoritative
• Client notifications: If data is confirmed stolen, affected clients may receive breach notifications
• Technical indicators: Organizations should check for Qilin-related IOCs, including the use of Mimikatz, EDRSandBlast, or MEGA uploads in their environments

For detection, security teams can reference YARA rules targeting Qilin’s custom PowerShell scripts (e.g., those used for vCenter/ESXi propagation) and monitor for unusual MEGA or EasyUpload.io traffic.
