MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a link farm and a specific malicious redirector URL. The document body, despite being heavily obfuscated, contains text related to 'free printable letter f coloring worksheets' and the malicious URL. The heuristic findings indicate the PDF links to known malicious redirector infrastructure and engages in SEO link farming, suggesting a lure to a malicious site. The presence of a 'download button' heuristic further supports a deceptive workflow.
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
-
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.ru/pify?keyword=free+printable+letter+f+coloring+worksheets
