MITRE ATT&CK

T1566.001 Spearphishing Attachment T1059.007 JavaScript

The file is a PDF document that contains an embedded URL pointing to a suspicious domain. ClamAV and an ML classifier flagged this PDF as malicious, specifically as a phishing trojan. The document body, though heavily obfuscated, suggests a lure related to 'chemical reaction arrow symbol'. The presence of an external URI and the high confidence scores from detection engines indicate a malicious intent, likely to redirect the user to a compromised site for further exploitation or credential harvesting.

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.
