MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is a PDF document exhibiting heuristics for a travel support phone scam and a general callback lure. The document body contains a large amount of obfuscated text, but the heuristics strongly indicate a social engineering attempt to trick the user into calling a provided phone number. No scripts were extracted, and the PDF structure itself does not reveal further malicious intent beyond the heuristic firings.

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.
