Adversaries may search for private key certificate files on compromised systems for insecurely stored credentials. Private cryptographic keys and certificates are used for authentication, encryption/decryption, and digital signatures.

Detect it with

Monitor access to files and directories related to cryptographic keys and certificates as a means for potentially detecting access patterns that may indicate collection and exfiltration activity.

Why it matters on shift

Private Keys is one of the concrete ways adversaries achieve credential access. Recognising it in telemetry lets you name the technique in your ticket and pivot to what came before and after.

What to look for next

After credential access, the next tactic is usually Discovery. Search your telemetry for the transition before closing the ticket.
