MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
T1204.002 Malicious Link
The PDF file contains a lure for an authorization letter example, which is a common tactic for phishing or malware delivery. It embeds numerous links, including one pointing to a known malicious redirector infrastructure at `https://ttraff.cc/pify?keyword=authorization+letter+example+pdf`. This indicates the document's primary purpose is to redirect the user to a malicious site, likely for further exploitation or credential harvesting. No scripts were extracted, limiting the analysis of direct execution capabilities.
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.
-
