  - M$ & (pid 672) (rule linux.malfind.Malfind) - memory signal, weight 0.60, confidence 0.85
• 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
• Contacted 8 external host(s) at runtime - network signal, weight 0.12, confidence 0.55
• Extracted generic config (1 C2) (generic/advisory) - engine signal, weight 0.15, confidence 0.30
