T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a lure related to 'Byju's learning app' and includes numerous embedded links. One critical heuristic indicates a malicious redirector link to 'ttraff.cc', suggesting the document is designed to redirect users to malicious content. The presence of a 'SE_ADVANCE_FEE_SCAM_LURE' heuristic further supports that this is likely an advance-fee fraud attempt, leveraging the embedded links to facilitate the scam.
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.
-
Advance-fee lottery/parcel scam lure high SE_ADVANCE_FEE_SCAM_LUREDocument contains lottery/beneficiary or prize language together with large-value draft/funds wording and parcel/courier delivery requirements. This is a classic advance-fee fraud document shape.
-
