About the Chaos group

Chaos is a ransomware-as-a-service operation that emerged in early 2025, likely formed by former BlackSuit/Royal members, offering cross-platform ransomware for Windows, Linux, ESXi, and NAS to affiliates recruited on the RAMP dark web forum, excluding CIS/BRICS countries and hospitals from targeting. Chaos has listed 95 victims since February 2025.

Incident analysis

DeCeTe was listed by Chaos ransomware, a group with 105 victims recorded in this database. The listing appeared on the group's leak site on October 28, 2025.

DeCeTe is based in Germany and operates in the Transportation/Logistics sector. Germany ranks #2 worldwide for ransomware disclosures, with 1,001 victims in this database.

Sector context. Logistics companies are targeted because supply chain disruption has cascading effects on customers and partners, amplifying pressure to pay ransoms quickly to restore operations.

Chaos typically follows a double extortion model: data is exfiltrated from the victim's systems before files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished. The leak site, where this listing appeared, is the lever for the second demand.

Source. Public leak-site disclosures aggregated via the ransomware.live API. The disclosure date is when the listing was published, which can differ from the date of compromise. This site does not publish or link to stolen data. Last updated .

As a Transportation/Logistics organisation, DeCeTe likely held sensitive business data, client information, and operational records.

How can organisations protect against Chaos attacks?

To defend against Chaos and similar threat actors, organisations should: maintain regular offline backups tested for restoration; implement network segmentation to limit lateral movement; deploy multi-factor authentication on all remote access; use endpoint detection and response (EDR) tools; conduct regular phishing and security awareness training; and monitor threat intelligence feeds for indicators of compromise (IOCs) associated with active groups.
