MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious Link

This PDF document contains numerous links, including a primary malicious redirector at https://ttraff.com/pify?keyword=uud+1945+hasil+amandemen+lengkap+pdf. The document body, though partially corrupted, appears to be a lure for a PDF file, likely intended to trick the user into downloading further malicious content. The presence of a malicious redirector and a link farm strongly suggests a phishing or malware distribution attempt.

Heuristics 3

PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

PDF 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_FARM

Small 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_URL

One 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.
