MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a critical heuristic firing indicating a link to known malicious redirector infrastructure. The embedded URL, 'https://ttraff.cc/pify?keyword=arab+news+newspaper+pdf', is the primary indicator of malicious intent. The ML classifier also strongly flagged this PDF as malicious. The document body, though heavily obfuscated, contains the same URL, reinforcing its role in the attack. No scripts were extracted, but the presence of a malicious redirector link is sufficient to infer a phishing or malware distribution attempt.

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.
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
-
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.cc/pify?keyword=arab+news+newspaper+pdf
