Note: This is a simulated, sanitized case study designed to demonstrate our investigative process without exposing sensitive client information.
CHALLENGE
A manufacturing client experienced suspicious file activity and subsequent encryption across multiple endpoints and file servers outside of standard business hours.
INVESTIGATION
EVIDEX deployed incident responders to isolate the affected network segments. We analyzed endpoint artifacts (Prefetch, event logs, registry keys), acquired volatile memory from key servers, and reconstructed the execution timeline.
FINDINGS
The investigation identified the initial access vector as a compromised VPN credential. The threat actor moved laterally using Living off the Land (LotL) techniques before deploying the ransomware payload via Group Policy.
OUTCOME
We provided the client with a precise timeline of attacker activity, identified all compromised accounts, and delivered actionable remediation recommendations, enabling a secure and confident recovery process.
