Incident Analysis

Premier Tax Services was targeted by Monti ransomware, one of the most active ransomware groups in our database with 63 confirmed victims globally. The attack was disclosed on November 19, 2024, when Premier Tax Services appeared on the group's dark web leak site.

Premier Tax Services is based in United States , operating in the Financial Services sector. United States ranks #1 globally for ransomware attacks, with 8,959 victims in our database.

Sector context: Financial sector organisations are targeted for their access to funds, sensitive financial data, and the reputational damage a public breach can cause. Regulatory requirements also increase recovery costs.

Monti 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 β€” 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.
