MITRE ATT&CK

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

The PDF contains a lure instructing the user to enable macros or editing, a common technique to bypass security settings. It also embeds numerous links, with at least one identified as a malicious redirector. The primary malicious URL identified is https://ttraff.ru/wix?keyword=libros+de+philip+kotler, which likely serves as a gateway to further malicious content. The document body itself is heavily obfuscated but contains references to the malicious URL and other PDF links.

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.
Macro/content-enable lure medium SE_ENABLE_LURE

Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
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.
