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

advantech.com was listed by Chaos ransomware, a group with 105 victims recorded in this database. The listing appeared on the group's leak site on September 29, 2026.

advantech.com is based in Taiwan and operates in the Manufacturing sector. Taiwan ranks #15 worldwide for ransomware disclosures, with 198 victims in this database.

Sector context. Manufacturing companies are frequently targeted because production downtime directly translates to financial loss. Ransomware operators exploit this time-sensitivity to demand higher ransoms and faster payment.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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 .
