HPK Hamburg Ransomware Claim by Safepay (May 2026)

Claim Summary

On May 1, 2026, the ransomware group known as Safepay allegedly added HPK Hamburg (hpk.hamburg) to its leak site. The threat actor claims to have compromised the Hamburg-based, family-run international trading company, which specializes in premium meat and seafood imports and has been in operation for over 50 years. According to the leak site post, Safepay asserts it has exfiltrated data from the organization, though the volume of stolen data remains undisclosed. This claim has not been independently verified by Yazoul Security, and no ransom demand or deadline has been publicly specified at this time.

Threat Actor Profile

Safepay is a ransomware group with limited public attribution. Based on available intelligence, the group has a small number of known victims, and no extensive research or public reporting exists on their operations. Their credibility is difficult to assess due to this lack of track record, but they have demonstrated technical capability through the use of specific tools observed in prior incidents.

Known tools associated with Safepay include:

• Invoke-ShareFinder – used for network share enumeration and data discovery.
• 7-Zip and WinRAR – used for compressing exfiltrated data.
• CMSTPLUA – a living-off-the-land binary (LOLBIN) used for privilege escalation or bypassing User Account Control.
• dllhost.exe and Regsvr32.exe – legitimate Windows processes abused for code execution and persistence.

The group’s reliance on LOLBins and standard compression tools suggests a focus on stealth and operational security, potentially indicating a more sophisticated threat actor than their victim count suggests.

Alleged Data Exposure

Safepay claims to have accessed and exfiltrated data from HPK Hamburg’s systems. The specific types of data allegedly stolen have not been detailed, but given the company’s role as a meat and seafood importer, potential data categories could include:

• Customer and supplier contracts
• Financial records and transaction histories
• Internal communications and email archives
• Supply chain and logistics data
• Employee personal information (PII)

The lack of data volume disclosure may indicate either a small-scale breach or an attempt by Safepay to maintain leverage by withholding details until negotiations progress.

Potential Impact

If the claim is validated, HPK Hamburg could face significant operational and reputational consequences. As a family-run international trading company with over 50 years of market presence, data exposure could damage client trust and supplier relationships. Financial losses may arise from ransom demands, regulatory fines under GDPR (given the German jurisdiction), and costs associated with incident response and system restoration. Supply chain disruptions are also possible if logistics data or supplier agreements were compromised.

What to Watch For

• Leak site updates – Monitor Safepay’s leak site for any posted data samples or ransom deadlines.
• Dark web chatter – Watch for discussions of HPK Hamburg data being traded or sold.
• Public statements – HPK Hamburg may issue a press release or regulatory notification if the breach is confirmed.
• Detection guidance – Organizations should review logs for use of the tools listed above (Invoke-ShareFinder, 7-Zip, WinRAR, CMSTPLUA, dllhost.exe, Regsvr32.exe) and consider implementing YARA rules to detect these artifacts.
