MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 User Execution: Malicious Link

The PDF contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic, pointing to various external domains. The document body explicitly requests sensitive information such as 'recovery phrases, private keys, backup codes, or saved passwords', aligning with the SE_SECRET_RECOVERY_LURE heuristic. This indicates a phishing attempt designed to steal credentials or financial information. The ClamAV detection further confirms its malicious nature.

Heuristics 4

  • 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.
  • Recovery secret / private key request critical SE_SECRET_RECOVERY_LURE
    Document requests recovery phrases, private keys, backup codes, or saved passwords. Requests for these secrets in a document are high-risk.
