MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous repetitions of phone numbers for 'United Airlines' customer support, strongly indicating a callback phishing or tech-support scam. The extensive stuffing of phone numbers and the context provided by the SE_TRAVEL_SUPPORT_PHONE_SCAM and SE_CALLBACK_LURE heuristics confirm the malicious intent. No scripts were extracted, but the document's content itself serves as the lure.

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.
