Why this verdict

The malicious score of 82/100 is the fusion of 8 weighted signals:

• capture keystrokes (rule capture keystrokes) - capa signal, weight 0.40, confidence 0.80
• Embedded executable payload carved at offset 30321 - static signal, weight 0.40, 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_AntiDebug_Checks (rule YR_AntiDebug_Checks) - engine signal, weight 0.35, confidence 0.70
• persist via registry run key (rule persist via registry run key) - capa signal, weight 0.35, confidence 0.60
• 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
• communicate over HTTP (rule communicate over HTTP) - capa signal, weight 0.30, 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.
