Spymel is a .NET information-stealing Trojan distributed via malicious JavaScript in email attachments; it uses compromised DigiCert-signed binaries, persists as svchost.exe/Startup32.1.exe, logs keystrokes, can record video, resists termination, communicates with C2 (android.sh / 213.136.92.111:1216), and includes several IoCs (file hashes, domain/IP, registry keys, file locations) that Zscaler ThreatLabZ analyzed and mitigated.
