MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file exhibits malicious behavior through numerous embedded links, with a critical heuristic identifying it as a link farm. One of the primary links, 'https://ttraff.com/pify?keyword=andrei+moreira+livros+pdf', is flagged as a malicious redirector. The document body, though heavily obfuscated, contains references to this URL and other Shopify-hosted PDF files, suggesting a coordinated effort to distribute malicious content or phish users. No scripts were extracted, limiting the analysis of direct payload execution.
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.
-
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=andrei+moreira+livros+pdf
