Incident analysis

Cooper Tec Solutions was listed by Hyflock ransomware, a group with 8 victims recorded in this database. The listing appeared on the group's leak site on October 13, 2026.

Cooper Tec Solutions is based in Brazil and operates in the Technology sector. Brazil ranks #7 worldwide for ransomware disclosures, with 520 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.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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