Why this verdict

The malicious score of 78/100 is the fusion of 5 weighted signals:

• Emsisoft (Emergency Kit) flagged PDF.Spam.Heur.1 (rule PDF.Spam.Heur.1) - engine signal, weight 0.55, confidence 0.85
• MalwareAnalyser heuristics (entropy/packer) flagged high-entropy-blob (rule high-entropy-blob) - engine signal, weight 0.35, confidence 0.70
• Embedded network infrastructure: https://ttraff.link/wix?keyword=shibumi+strategy+pdf, https://cdn.shopify.com/s/files/1/0428/0185/6668/files/sax_sheet_music_jazz.pdf, https://cdn.shopify.com/s/files/1/0431/3264/9636/files/dekuwu.pdf - static signal, weight 0.35, confidence 0.60
• Document active content: uri-action - static signal, weight 0.30, confidence 0.60
• Packing/obfuscation: high-entropy-blob - static signal, weight 0.25, confidence 0.55

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.
