T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file was identified as malicious due to its use of a link farm containing numerous external PDF links, many of which point to potentially malicious redirectors. The primary malicious URL identified is https://ttraff.ru/pify?keyword=icse+2020+syllabus+pdf. The document body contains garbled text but also includes the suspicious URL, suggesting an attempt to lure users into clicking malicious links under the guise of providing syllabus information.
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.
-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
