T1566.001 Spearphishing Attachment
T1059.007 JavaScript
This PDF file contains numerous links to external websites, many of which are part of a link farm designed to obscure malicious destinations. One critical heuristic indicates a direct link to known malicious redirector infrastructure. The document body, though heavily obfuscated, suggests a lure related to 'Events in la calendar', likely to trick users into clicking the embedded malicious links.

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.

Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
