Incident analysis

Strata Republic was listed by Kairos ransomware, a group with 107 victims recorded in this database. The listing appeared on the group's leak site on April 17, 2026.

Strata Republic is based in Australia and operates in the Business Services sector. Australia ranks #10 worldwide for ransomware disclosures, with 418 victims in this database.

Sector context. Business services firms often have access to multiple client environments, making them high-value pivot points for ransomware operators seeking to maximise impact across multiple victim organisations.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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