• Kaspersky (KVRT) flagged HEUR:Backdoor.Linux.Mirai.h (rule HEUR:Backdoor.Linux.Mirai.h) - engine signal, weight 0.55, confidence 0.85
• YARA: Intezer community flagged INTEZER_ELF_UPX_Modified (rule INTEZER_ELF_UPX_Modified) - engine signal, weight 0.40, 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
• MalwareAnalyser heuristics (entropy/packer) flagged high-entropy-blob (rule high-entropy-blob) - 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
• Contacted 2 external host(s) at runtime - network signal, weight 0.12, confidence 0.55
