T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document contains a heuristic firing for a link farm, indicating a large number of external links. The document body, though heavily obfuscated, contains text related to a job posting ('Practicante ingenieria financiera medellin'). The presence of numerous external links, including one to 'roguerobotics.net' and several to 'simpletravelin.com' and similar domains, suggests a phishing or malware distribution attempt. No scripts were extracted from this sample.

Heuristics 4
-
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.
-
External URI info PDF_URIPDF contains an external URL action
-
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.
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL http://roguerobotics.net/uploads/1/3/0/5/130540645/130540645.html#practicante+ingenieria+financiera+medellin PDF link annotation
