The PDF was flagged by multiple heuristics, including ClamAV and an ML classifier, indicating malicious intent. The critical PDF_SEO_LINK_FARM heuristic fired, revealing a mass of external PDF links, with the primary URL being http://fukizonug.cryptopress.pro/uploads/2020/01/29/vexakosotulod-dazogusel-kiposepadajurer-kizumasafu.pdf. This suggests a phishing or malware distribution campaign leveraging SEO techniques to disguise malicious links. No scripts were extracted, but the embedded URLs are the primary indicators of compromise.
