Incident Analysis

HIZE Aero was targeted by Ulose ransomware, one of the most active ransomware groups in our database with 5 confirmed victims globally. The attack was disclosed on June 9, 2026, when HIZE Aero appeared on the group's dark web leak site.

HIZE Aero is based in South Korea , operating in the Manufacturing sector. South Korea ranks #29 globally for ransomware attacks, with 114 victims in our 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.

Ulose typically employs a double extortion model: first exfiltrating sensitive data from the victim's systems, then deploying ransomware to encrypt files. Victims face two simultaneous threats — paying to restore access and paying to prevent publication of stolen data. The group's leak site publishes victim names and exfiltrated data as leverage.

Data source: This incident record is sourced from public ransomware group leak site disclosures aggregated via the ransomware.live API. Disclosure date reflects when the victim was published on the leak site, which may differ from the initial date of compromise. This platform does not publish or link to stolen data.
