Incident Analysis
www.obrienavocats.qc.ca was targeted by Ransomhub ransomware, one of the most active ransomware groups in our database with 842 confirmed victims globally. The attack was disclosed on February 26, 2025, when www.obrienavocats.qc.ca appeared on the group's dark web leak site.
www.obrienavocats.qc.ca is based in Canada , operating in the Business Services sector. Canada ranks #2 globally for ransomware attacks, with 875 victims in our 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.
Ransomhub 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 โ 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.
