Why this verdict

The malicious score of 98/100 is the fusion of 9 weighted signals:

• ClamAV (daily) flagged Win.Malware.Hoax-10029094-0 (rule Win.Malware.Hoax-10029094-0) - engine signal, weight 0.90, confidence 0.95
• capture keystrokes (rule capture keystrokes) - capa signal, weight 0.40, confidence 0.80
• 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:Microsoft Linker (rule DIE:Microsoft Linker) - 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

• enumerate processes (rule enumerate processes) - capa signal, weight 0.20, confidence 0.60

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.
