Thwarting a Coordinated Ransomware Attack in Real-Time

A rapidly growing regional financial services firm became the target of a highly coordinated spear-phishing campaign. An employee unknowingly executed a zero-day ransomware payload that evaded their traditional endpoint antivirus. The malware began rapidly encrypting mapped network drives containing sensitive client portfolios.

Because the client was under our Managed IT Service, our 24/7 Network Operations Center (N.O.C) detected the anomalous encryption behavior via our heuristic monitoring tools within 3 minutes of the initial execution.

Our automated containment protocols instantly isolated the infected subnet from the rest of the corporate network. We immediately invoked the immutable backup architecture. Because the backups were stored in a physically air-gapped environment with "write-once, read-many" (WORM) storage, the ransomware could not touch the clean data.

The threat was fully contained within 15 minutes. Our team restored the affected drives from the immutable snapshot taken just 1 hour prior to the attack. Zero bytes of sensitive client data were lost, and zero ransom was paid. The client avoided a devastating regulatory fine and catastrophic reputational damage.
