MITRE ATT&CK

Why this verdict

The malicious score of 89/100 is the fusion of 6 weighted signals:

Memory forensics: 1 finding(s) attributed to the sample across 1 technique(s), e.g. RWX/private injected region in tsk_41c7ca175c (pid 3952) (rule windows.malfind.Malfind) - memory signal, weight 0.60, confidence 0.85
access stored credentials (rule access stored credentials) - capa signal, weight 0.50, confidence 0.80
Contacted 1 external host(s) and 3 HTTP request(s) at runtime - network signal, weight 0.40, confidence 0.80
LIEF (executable format parser) flagged lief:invalid-authenticode (rule lief:invalid-authenticode) - engine signal, weight 0.35, confidence 0.70
capa (capabilities) flagged capability:credential-access (rule capability:credential-access) - engine signal, weight 0.35, confidence 0.70
Memory forensics: 3 finding(s) elsewhere in the guest, not attributed to this sample, e.g. process hidden from a listing (rule windows.psxview.PsXView) - memory signal, weight 0.05, confidence 0.30
