MITRE ATT&CK
T1566.001 Spearphishing Attachment T1598.002 URL/Domain Link

This PDF file exhibits characteristics of a phishing or callback scam. The document body, though heavily obfuscated, contains references to 'Union bank of india online personal login', suggesting a lure to trick users into providing sensitive information. The presence of a large number of external PDF links, many pointing to similarly structured URLs, indicates a link farm designed to distribute malicious content or redirect users. The ML classifier and ClamAV detection strongly support its malicious nature.

  • Callback phishing phone lure medium SE_CALLBACK_LURE
    Document asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns. Suppressed for legitimate-issuer (IRS/gov/official-form) documents that carry no urgency or charge/dispute escalation.
  • 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.
