Why this verdict

The malicious score of 88/100 is the fusion of 7 weighted signals:

• Kaspersky (KVRT) flagged Worm.Win32.AutoRun.vx (rule Worm.Win32.AutoRun.vx) - engine signal, weight 0.55, confidence 0.85
• YARA: delivr.to detections flagged DLV_ISO_IMG_Container_Lure (rule DLV_ISO_IMG_Container_Lure) - engine signal, weight 0.35, confidence 0.70
• YARA: JPCERT/CC flagged JPCERT_HUILoader_PlugX_SideLoad (rule JPCERT_HUILoader_PlugX_SideLoad) - engine signal, weight 0.35, confidence 0.70
• YARA: Yara-Rules community flagged YR_Packer_ASPack_MPRESS (rule YR_Packer_ASPack_MPRESS) - engine signal, weight 0.35, confidence 0.70
• Detect It Easy (packer/type) flagged DIE:ASProtect SKE 2.72+ (rule DIE:ASProtect SKE 2.72+) - engine signal, weight 0.35, confidence 0.70
• Embedded network infrastructure: http://www.gnu.org/software/coreutils/, http://translationproject.org/team/, http://gnu.org/licenses/gpl.html - static signal, weight 0.35, confidence 0.60
• Packing/obfuscation: ASPack, high-entropy-sections:.text, ASProtect SKE 2.72+, ASPack 2.12-2.42 - 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.
