About the Global group

GLOBAL GROUP is a ransomware-as-a-service operation that emerged in June 2025, reportedly launched by a known Russian-speaking threat actor, featuring AI-driven ransom negotiation and a mobile control panel for affiliates, targeting healthcare, oil and gas, industrial engineering, and automotive sectors. Global has listed 38 victims since May 2025.

Incident analysis

Atcomm 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.

Atcomm is based in China and operates in the Technology sector. China ranks #28 worldwide for ransomware disclosures, with 126 victims in this database.

Sector context. Technology companies hold intellectual property, customer data, and source code — all highly valuable assets. A successful ransomware attack can also put downstream customers at risk through supply chain exposure.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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