Incident analysis

AYUDHYA TH Insurance was listed by Dysphor1a ransomware, a group with 11 victims recorded in this database. The listing appeared on the group's leak site on August 20, 2026.

AYUDHYA TH Insurance is based in Thailand and operates in the Financial Services sector. Thailand ranks #17 worldwide for ransomware disclosures, with 190 victims in this database.

Sector context. Financial sector organisations are targeted for their access to funds, sensitive financial data, and the reputational damage a public breach can cause. Regulatory requirements also increase recovery costs.

Dysphor1a 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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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 .
