Detections (6 of 56 engines)

• MalwareAnalyser heuristics (entropy/packer): high-entropy-blob
• YARA: Intezer community: INTEZER_ELF_UPX_Modified
• Detect It Easy (packer/type): DIE:UPX 3.94

• Kaspersky (KVRT): HEUR:Backdoor.Linux.Mirai.h

Why this verdict

The suspicious score of 61/100 is the fusion of 4 weighted signals:

• YARA: Intezer community flagged INTEZER_ELF_UPX_Modified (rule INTEZER_ELF_UPX_Modified) - engine signal, weight 0.35, confidence 0.70
• Detect It Easy (packer/type) flagged DIE:UPX 3.94 (rule DIE:UPX 3.94) - 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: high-entropy-blob, UPX 3.94 - static signal, weight 0.25, confidence 0.55

Dynamic analysis

This sample is built for ARM, which no sandbox guest in our fleet executes, so it was not detonated. The absence of runtime behaviour here is a coverage gap on our side, not a finding about the sample.
