T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a large number of links to other PDF documents, many hosted on Shopify, which is indicative of a link farm. One of these links, 'https://ttraff.cc/pify?keyword=spring+boot+jasper+report+subreport', is identified as a malicious redirector. The ML classifier also strongly flagged this PDF as malicious. The document body contains garbled text but includes the malicious redirector URL and several benign-looking Shopify PDF links.

Heuristics 3
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF 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_FARMSmall 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.
