MITRE ATT&CK

T1566.002 Spearphishing Attachment T1059.001 PowerShell T1204.002 Malicious Link

The PDF document contains a lure related to 'Iti admission punjab form 2019' and includes a critical heuristic firing for a malicious redirector link pointing to 'https://ttraff.cc/pify?keyword=iti+admission+punjab+form+2019'. Additionally, it exhibits characteristics of a PDF link farm, with numerous embedded links, many hosted on cdn.shopify.com. The document body, though partially garbled, contains the redirector URL and text suggesting an invoice or payment lure. The primary attack pattern involves tricking the user into clicking the malicious link under the guise of an admission form.

Heuristics 4

PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

PDF 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_FARM

Small 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_LURE

Document contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
Embedded URL info EMBEDDED_URL

One 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.
