MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file contains numerous embedded links, with one specifically pointing to a known malicious redirector. The document body, though partially corrupted, includes text suggesting a technical reference, which is likely a lure. The heuristic firings confirm the presence of malicious redirector links and a link farm, indicating a coordinated effort to drive traffic to malicious sites. The primary attack pattern involves using a seemingly legitimate document to trick users into visiting a malicious URL.
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.cc/pify?keyword=algorithms+in+a+nutshell+a+desktop+quick+reference+pdf
