MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
T1204.002 Malicious Link
The PDF contains a link farm designed to appear as legitimate exercise PDFs, but the primary link redirects to a malicious redirector. The embedded URL `https://ttraff.cc/pify?keyword=analise+combinatoria+exercicios+pdf` is a critical indicator of malicious intent, likely serving as a lure to a phishing or malware distribution site. The presence of numerous other PDF links, many hosted on Shopify, suggests a coordinated effort to manipulate search engine results or distribute malicious content.
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.
