MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

This PDF file was flagged as malicious by a machine learning classifier and ClamAV. It contains an embedded URI pointing to 'https://xezojetit.ru/wix?keyword=peoria+manual+high+school', suggesting a phishing or redirection attempt. The document body, though heavily obfuscated, contains text related to 'Peoria manual high school' and the authoring application, likely as a lure. No scripts were extracted, but the presence of embedded URLs and the ML/ClamAV detections strongly indicate malicious intent.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL
    The same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
  • 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.
