MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a large number of embedded URLs, identified as a link farm. This is strongly indicative of a phishing or SEO poisoning attack, aiming to redirect users to malicious websites. The ClamAV detection further supports its malicious nature. No scripts were extracted, and the document body was heavily corrupted, limiting further analysis of specific lures.

    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.
