Incident analysis

CFG SERRAMENTI S.r.l. was listed by Majinahanashi ransomware, a group with 49 victims recorded in this database. The listing appeared on the group's leak site on October 24, 2026.

CFG SERRAMENTI S.r.l. is based in Italy and operates in the Manufacturing sector. Italy ranks #5 worldwide for ransomware disclosures, with 617 victims in this database.

Sector context. Manufacturing companies are frequently targeted because production downtime directly translates to financial loss. Ransomware operators exploit this time-sensitivity to demand higher ransoms and faster payment.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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