Call Stacks: No More Free Passes For Malware

Elastic Security Labs technical overview of Windows call stacks: explains how call stacks are recovered (stack walking vs CPU tracing), how addresses are enriched with module exports or public symbols, common malware evasion techniques (tail calls, trampoline frames, return-address spoofing), and the heuristics Elastic uses (e.g., proxy_call, shellcode, unbacked_rwx) to surface and triage suspicious activity from endpoint telemetry.
