Why this verdict

The malicious score of 77/100 is the fusion of 7 weighted signals:

Contacted 3 HTTP request(s) at runtime - network signal, weight 0.40, confidence 0.80
Detect It Easy (packer/type) flagged DIE:Microsoft Visual Basic (rule DIE:Microsoft Visual Basic) - engine signal, weight 0.35, confidence 0.70
MalwareAnalyser heuristics (entropy/packer) flagged high-entropy-sections:.MPRESS1 (rule high-entropy-sections:.MPRESS1) - engine signal, weight 0.35, confidence 0.70
YARA: Yara-Rules community flagged YR_Packer_ASPack_MPRESS (rule YR_Packer_ASPack_MPRESS) - engine signal, weight 0.30, confidence 0.70
Packing/obfuscation: high-entropy-sections:.MPRESS1, Microsoft Visual Basic - static signal, weight 0.25, confidence 0.55
Observed at runtime: Modify Registry (T1112) (rule Modify Registry) - dynamic signal, weight 0.12, confidence 0.90
Memory forensics: 2 finding(s) elsewhere in the guest, not attributed to this sample, e.g. SSDT hook (rule windows.ssdt.SSDT) - memory signal, weight 0.05, confidence 0.30
