Why this verdict

The malicious score of 87/100 is the fusion of 2 weighted signals:

• ClamAV (daily) flagged Win.Trojan.Small-5420 (rule Win.Trojan.Small-5420) - engine signal, weight 0.90, confidence 0.95
• Packing/obfuscation: high-entropy-sections:.text - static signal, weight 0.25, confidence 0.55

Dynamic analysis

No runtime behaviour was captured for this sample, so the analysis above is static only. That is a limit of this run rather than evidence the sample does nothing.
