Companion lab to the MCP Prompt Injection Kill Chain, focused on malicious browser extensions attempting credential exfiltration.

What the lab covers

Five distinct attack patterns, all inert, walking through how a malicious browser extension attempts credential theft under different technique variations. Each pattern includes XSIAM correlation walkthrough illustrating detection surfaces available in AES.

Detection surfaces demonstrated

Browser extension inventory and permission analysis
Runtime behavior monitoring for credential access patterns
Outbound data flow correlation
XSIAM case correlation across the five variations
