Incident analysis

Hangzhou Qihan Biotech Co., Ltd. was listed by Global ransomware, a group with 40 victims recorded in this database. The listing appeared on the group's leak site on August 28, 2026.

Hangzhou Qihan Biotech Co., Ltd. is based in China and operates in the Healthcare sector. China ranks #28 worldwide for ransomware disclosures, with 126 victims in this database.

Sector context. Healthcare organisations are high-value ransomware targets because patient data is extremely sensitive, regulatory penalties for breaches are severe, and operational downtime can threaten patient safety — all factors that increase ransom payment pressure.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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