Incident analysis

광명산업(주) was listed by Blacklocks ransomware, a group with 4 victims recorded in this database. The listing appeared on the group's leak site on September 5, 2026.

광명산업(주) is based in South Korea and operates in the Manufacturing sector. South Korea ranks #26 worldwide for ransomware disclosures, with 132 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.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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