Compiled from this incident record and the threat intelligence profile for Osiris. Figures and technique mappings are quoted from the source data, not inferred.

About the Osiris group

Osiris is a ransomware-as-a-service operation first observed in November 2025 that uses a Bring Your Own Vulnerable Driver (BYOVD) technique to disable endpoint detection tools before deploying hybrid ECC + AES-128-CTR encryption; Symantec researchers linked its operators to former INC ransomware affiliates. Osiris has listed 2 victims since December 2025.

Incident analysis

NUCO Controls was listed by Osiris ransomware, a group with 10 victims recorded in this database. The listing appeared on the group's leak site on November 11, 2026.

NUCO Controls is based in United States and operates in the Manufacturing sector. United States ranks #1 worldwide for ransomware disclosures, with 10,481 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.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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