Incident Analysis

First Secure Community Bank was targeted by Storm ransomware, one of the most active ransomware groups in our database with 61 confirmed victims globally. The attack was disclosed on September 18, 2026, when First Secure Community Bank appeared on the group's dark web leak site.

First Secure Community Bank is based in United States , operating in the Financial Services sector. United States ranks #1 globally for ransomware attacks, with 9,532 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.

Storm 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.
