The PDF file contains a heuristic firing for a malicious redirector link and a link farm, indicating an attempt to lead the user to malicious sites. The document body text and heuristics suggest a lure related to an 'Nbi online application form'. The primary malicious URL identified is https://ttraff.com/pify?keyword=nbi+online+application+form+pdf, which is likely used to redirect the user to a further malicious destination.
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.
-
Fake invoice / payment lure low SE_INVOICE_LUREDocument contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
-
