T1566.002 Spearphishing Attachment
T1059.001 PowerShell
T1204.001 Malicious Link
The PDF contains multiple embedded links, with one specifically pointing to a known malicious redirector at 'ttraff.ru'. The document body, though heavily obfuscated, contains text fragments related to 'e filing' and '26as form', suggesting a lure for financial or tax-related phishing. The heuristic 'SE_MFA_LURE' further indicates an attempt to harvest credentials or session tokens by mimicking a multi-factor authentication prompt. The presence of a link farm also suggests an attempt to game search engine results for broader reach.
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.
-
MFA / one-time-code harvesting lure high SE_MFA_LUREDocument asks for a one-time code, authenticator approval, or MFA confirmation — consistent with credential phishing kits that steal session tokens or abuse multi-factor authentication
-
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=e+filing+26as+form
