Inspira Ransomware Attack by Qilin (April 2026)

Claim Summary

On April 27, 2026, the Qilin ransomware group allegedly added Inspira, operating under the domain inspirapr.com in Puerto Rico, to their dark web leak site. The threat actor claims to have successfully breached the organization’s network and exfiltrated data, though no specific data samples, file listings, or volume details have been released at this time. The attack date is listed as April 27, 2026. This claim remains unverified by Yazoul Security.

Threat Actor Profile

Qilin (also tracked as Agenda) is a ransomware-as-a-service (RaaS) group first observed in 2022. According to available intelligence, the group has claimed 1,617 victims to date, indicating a high-volume, aggressive operational tempo. Qilin is known for targeting a wide range of sectors, including healthcare, education, and government.

The group’s known toolset includes:

• Reconnaissance and credential theft: Mimikatz, Nmap, Nping
• Defense evasion: EDRSandBlast, PCHunter, PowerTool
• Exfiltration: EasyUpload.io, MEGA

Qilin has been observed propagating to VMware vCenter and ESXi environments via custom PowerShell scripts, as documented by Trend Micro. The group also employs SMS phishing and SIM swapping as initial access vectors, according to Google Cloud’s Threat Intelligence. SecureWorks tracks the group under the moniker “Gold Feather.”

Credibility assessment: Qilin is a well-established, technically capable ransomware group with a proven track record of successful attacks. Their high victim count (1,617) suggests a functioning affiliate program and consistent operational capability. However, the lack of published data in this specific claim warrants caution, as threat actors sometimes bluff to pressure victims.

Alleged Data Exposure

The Qilin leak site entry for Inspira does not specify the type or volume of data allegedly stolen. No screenshots, file lists, or sample documents have been published. This could indicate:

• The group is still negotiating with the victim and has not yet released proof.
• The claim is a bluff or an attempt to force a ransom payment without actual data.
• The data is being prepared for publication on a future date.

Without published evidence, the scope and sensitivity of any alleged breach remain unknown.

Potential Impact

If the claim is verified, Inspira could face:

• Operational disruption: Potential encryption of critical systems, leading to downtime.
• Data breach liability: Exposure of customer, employee, or partner data, depending on the nature of Inspira’s business.
• Regulatory consequences: Puerto Rico’s data breach notification laws and potential federal implications.
• Reputational harm: Loss of trust among clients and partners.

Given that Inspira’s industry is not specified, the impact assessment is limited. However, any ransomware incident carries significant financial and operational risks.

What to Watch For

• Proof of data: Monitor for any future publication of data samples or file lists by Qilin.
• Public statements: Inspira may issue a press release or regulatory filing if the breach is confirmed.
• Technical indicators: Look for Qilin-related IOCs, including known C2 domains, hashes, and tools (Mimikatz, EDRSandBlast).
• YARA rules: Security researchers have published YARA rules for Qilin/Agenda ransomware. Organizations should review and deploy these rules for detection.
