Malware Insights
The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'https://ttraff.com/wix?keyword=contoh+soal+tkb+agama+islam+pdf'. It also exhibits characteristics of a PDF SEO link farm, embedding numerous external links, with 'https://static.usrfiles.com/ugd/b8c837_432cfe9ff0eb48fca92d68034e3bf6a2.pdf' being a prominent example. The document body, though heavily obfuscated, contains text related to search terms and the wkhtmltopdf application, suggesting a lure to disguise malicious links as search results. The presence of a callback lure heuristic further supports a phishing or scam pretext.
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.
-
Callback phishing phone lure medium SE_CALLBACK_LUREDocument asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns
-
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/wix?keyword=contoh+soal+tkb+agama+islam+pdf
