MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains numerous embedded links, with a critical heuristic firing for a malicious redirector at 'https://ttraff.com/wb?keyword=combine%20multiple%20pdfs%20into%20one%20file%20without%20adobe%20acrobat'. This suggests a social engineering attack aiming to trick users into downloading further malware or visiting malicious sites. The document body, though partially corrupted, also contains this URL, reinforcing the lure. The presence of many other PDF links, some benign and some unknown, indicates a link farm strategy to obscure the malicious destination.
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/wb?keyword=combine%20multiple%20pdfs%20into%20one%20file%20without%20adobe%20acrobat
