Distrigaz Vest Ransomware Attack by INC Ransom (May 2026)

Claim Summary

On May 27, 2026, the ransomware group INC Ransom (incransom) posted a claim on its dark web leak site alleging a successful intrusion against Distrigaz Vest S.A., an independent natural gas distributor based in Oradea, Romania. According to the threat actor, the attack resulted in the exfiltration of approximately 100GB of data. The group claims to have accessed a wide range of sensitive information, including confidential documents, client data, NDAs, financial records, operational data, corporate agreements, and development files. The claim includes specific financial figures for the company’s 2024 fiscal year, suggesting the threat actor may have accessed internal reporting. This incident has not been independently verified by Yazoul Security, and Distrigaz Vest S.A. has not issued a public statement at the time of writing.

Threat Actor Profile

INC Ransom is a ransomware group that has been active since at least 2023, known for targeting organizations across multiple sectors, including energy, healthcare, and manufacturing. The group typically employs a double-extortion model: encrypting victim systems while exfiltrating data to pressure victims into paying a ransom. Based on observed tooling, INC Ransom operators commonly use:

• Mimikatz for credential dumping
• AdFind for Active Directory reconnaissance
• Advanced IP Scanner and SoftPerfect NetScan for network enumeration
• 7-Zip for data compression
• BackBlaze and MEGA for exfiltration
• Finger for user enumeration

The group’s credibility is moderate. While they have successfully claimed victims in the past, ransomware groups routinely exaggerate the scale and sensitivity of stolen data to increase pressure. Without independent verification, this claim should be treated with caution. No public YARA rules or detection signatures specific to INC Ransom are currently available, though defenders should monitor for the tools listed above in their environments.

Alleged Data Exposure

According to the leak site post, the threat actor claims to have exfiltrated 100GB of data from Distrigaz Vest S.A. The alleged categories include:

• Confidential documents
• Client data
• Non-disclosure agreements (NDAs)
• Financial data, including transaction records and databases
• Operational and corporate data
• Business agreements
• Development files

The group also claims to have accessed “all clients” and “all transactions,” which, if true, could represent a significant breach of customer and business partner confidentiality. The inclusion of specific financial metrics (2024 turnover of RON 86.53 million and net profit of RON 9.89 million) suggests the attacker may have accessed internal financial reporting systems.

Potential Impact

If the claim is verified, the potential impact on Distrigaz Vest S.A. could be substantial:

• Operational disruption: As an exclusive natural gas distributor for Oradea, any service interruption could affect thousands of residential and commercial customers.
• Regulatory consequences: Under Romania’s data protection laws (GDPR implementation), a breach involving client data could result in significant fines and mandatory notifications.
• Reputational damage: Public disclosure of sensitive business agreements and financial data could harm relationships with partners and investors.
• Financial loss: Beyond potential ransom demands, the company may face costs related to incident response, legal fees, and system restoration.

What to Watch For

• Official confirmation: Monitor Distrigaz Vest S.A.’s official website and Romanian energy regulatory bodies for any statements.
• Data leaks: If the group follows through with its threats, portions of the stolen data may appear on leak sites or forums. Do not access or download such data.
• Phishing campaigns: Stolen client data could be used in targeted phishing attacks against customers or business partners.
• Regulatory updates: The Romanian National Authority for Data Protection (ANSPDCP) may open an investigation if the breach is confirmed.
