About the Fulcrumsec group

Fulcrumsec has listed 27 victims since May 2026.

Incident analysis

PingCAP / TiDB Cloud was listed by Fulcrumsec ransomware, a group with 29 victims recorded in this database. The listing appeared on the group's leak site on October 19, 2026.

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.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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