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_a44b157a70 (pid 5364) (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 17 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: 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
