OVERVIEW

Case Overview

A mid-sized financial services firm experienced a severe ransomware attack that encrypted over 80% of their critical servers, halting all operations including client transactions, internal communications, and data access. The attackers demanded a substantial Bitcoin payment within 72 hours.

Our team was brought in as an emergency response unit to assess the damage, contain the breach, and restore operations. Working around the clock, we deployed advanced decryption tools, isolated infected segments, and rebuilt compromised systems from secure backups.

The entire recovery process was completed within 48 hours, with zero data loss and no ransom paid. Post-incident, we implemented a comprehensive security framework to prevent future attacks.
