Why this verdict

The malicious score of 94/100 is the fusion of 5 weighted signals:

• ClamAV (daily) flagged Win.Malware.Sivis-9908038-0 (rule Win.Malware.Sivis-9908038-0) - engine signal, weight 0.90, confidence 0.95
• YARA: JPCERT/CC flagged JPCERT_HUILoader_PlugX_SideLoad (rule JPCERT_HUILoader_PlugX_SideLoad) - engine signal, weight 0.35, confidence 0.70
• Detect It Easy (packer/type) flagged DIE:UPX (rule DIE:UPX) - engine signal, weight 0.35, confidence 0.70
• Embedded network infrastructure: https://d.symcb.com/rpa0, http://s.symcb.com/universal-root.crl0, https://d.symcb.com/rpa0@ - static signal, weight 0.35, confidence 0.60
• Packing/obfuscation: UPX, high-entropy-sections:UPX1 - 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.
