MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF contains numerous links, with one critical heuristic identifying a link to known malicious redirector infrastructure. The document body, though heavily obfuscated, suggests a lure related to a 'big fighting game mod apk'. The presence of multiple external PDF links, some benign and some unknown, indicates a link farm strategy. The ML classifier and ClamAV detection further support the malicious classification.

PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
