Aeternum Loader: Inside the binary

This technical analysis dissects the Aeternum Loader: a Windows malware loader that uses per-string XOR and API-hashing obfuscation, anti-VM and Russian geofencing checks (CPUID EAX=6, SMBIOS, USB history, locale), persistence via Startup .lnk entries, NTFS ADS-based self-deletion, PPID spoofing, reflective DLL loading, and blockchain-based C2 (Polygon contract 0x4d70C3393C5d9EC325Edf8b3f289cFA9777e64B0) where AES-encrypted commands are retrieved and decrypted; the report supplies decryption code, hashing algorithms, sample commands/URLs, and numerous IOCs useful for detection and response.
