WHOIS

description
Forensic analysis indicates a DocuSign-themed phishing campaign using a deliberately invalid X.509 PKI seal (“Broken Seal”) to trigger fail-open verification logic in automated handlers. The delivery mechanism bypasses Secure Email Gateway (SEG) reputation checks by using encrypted channels and human-gated infrastructure. The payload is a fileless Process Hollowing (RunPE) malware that injects into RWX memory of legitimate processes to evade disk-based EDR.
