Why this verdict

The malicious score of 93/100 is the fusion of 4 weighted signals:

• ClamAV (daily) flagged Win.Virus.Pioneer-9111434-0 (rule Win.Virus.Pioneer-9111434-0) - engine signal, weight 0.90, confidence 0.95
• Detect It Easy (packer/type) flagged DIE:Microsoft Linker (rule DIE:Microsoft Linker) - engine signal, weight 0.35, confidence 0.70
• Embedded network infrastructure: http://upx.sf.net - static signal, weight 0.35, confidence 0.60
• Packing/obfuscation: UPX, high-entropy-sections:UPX1, Microsoft Linker - 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.
