T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file contains embedded JavaScript and links to a known malicious redirector. The document body text, though partially corrupted, includes a lure related to 'Acta constitutiva de una empresa formato pdf' and the primary URL points to a redirector that likely serves malicious content. The presence of numerous external PDF links suggests a link farm or SEO poisoning tactic to distribute the malicious payload.
Heuristics 4
-
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.
-
Embedded JS stream low PDF_JSPDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
-
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 https://ttraff.com/pify?keyword=acta+constitutiva+de+una+empresa+formato+pdf
