T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a link to a redirector URL that is flagged as malicious. The document body, though heavily obfuscated, appears to be a lure related to 'happy birthday cake with name images'. The PDF also contains a large number of external links, many hosted on Shopify, which is indicative of a link farm used for SEO poisoning or to distribute malicious content. No scripts were extracted from this sample.

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.
-
