MITRE ATT&CK
T1566.001 Spearphishing Attachment

The sample triggered heuristics for a travel support phone scam and a general callback lure, indicating a social engineering attempt. The document body was heavily obfuscated and truncated, preventing a deeper analysis of its specific content or potential embedded scripts. No other IOCs were extracted.

Machine Learning

  • Nyx PDF Classifier clean score 0.0001

Heuristics 2

  • Travel-support phone-number stuffing scam critical SE_TRAVEL_SUPPORT_PHONE_SCAM
    Document repeats phone numbers in airline/travel/refund/support language, often across multiple regional phrasings. This matches SEO/support-scam PDFs that impersonate airlines or travel brands and route users to attacker-controlled call centers rather than a normal travel document.
  • 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) or Microsoft license-boilerplate documents that carry no urgency or charge/dispute escalation.
