MITRE ATT&CK

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

The PDF file contains numerous embedded links, a technique often used to obscure malicious destinations. One such link, 'https://ttraff.com/pify?keyword=champions+league+calendario+2020+pdf', is identified as a malicious redirector. The document body, though heavily obfuscated, suggests a lure related to the 'Champions league calendario 2020 pdf'. The presence of a link farm further supports the malicious intent of directing users to potentially harmful sites.

Heuristics 3

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.
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.
