Ransomware Containment & Recovery for a Regional Bank
A regional retail bank (anonymized)
Illustrative example. This scenario is a representative composite used to demonstrate our engagement approach, not a specific named client. Real case studies will replace this content as they are published.
The Challenge
A regional retail bank detected unusual encryption activity across branch file servers overnight, consistent with an active ransomware event. Leadership needed rapid containment while preserving evidence for regulatory reporting.
The Investigation
Our incident response team was engaged to isolate affected segments, identify the initial access vector, and determine the scope of lateral movement, while forensic analysts began evidence preservation in parallel to support the bank's regulatory obligations.
The Solution
Affected systems were isolated from the network, credentials associated with the compromised account were revoked, and a phased recovery plan restored branch operations from clean backups. A forensic report documented the incident timeline for the board and regulator.
Technology & Approach
- terminalEndpoint isolation and network segmentation
- terminalForensic disk and memory imaging
- terminalLog correlation across branch and core banking systems
Illustrative Results

"The response was structured and fast — we had a clear picture of what happened and what to tell our regulator well before we expected to."
