What Happened?
First Secure Community Bank was listed in a ransomware leak-site allegation reported by Ransomware.live on September 18th, 2026. The Storm ransomware group — tracked by Microsoft as Storm-1175 — posted the claim on its dark web leak site. No independent confirmation of the incident by the bank, any regulator, or mainstream media was found. The claim should be treated as an unverified attacker allegation. No specific data types, data volumes, breach date, or discovery date were stated in the claim.
The Storm group (Storm-1175) is a financially motivated threat actor that began deploying a custom ransomware strain called StormEncryptor in August 2026, exploiting CVE-2026-18577, an authentication-bypass vulnerability in N-able N-central remote monitoring and management software. Microsoft assesses Storm-1175 as likely operating from a UTC+8 timezone consistent with Chinese-speaking regions and has previously associated the group with Medusa ransomware. The group has been actively posting claims against multiple U.S. organizations since August 2026. No prior data breaches or cybersecurity incidents involving First Secure Community Bank were found in public sources, and no litigation connected to this incident has been identified.
