MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was detected as malicious by ClamAV and an ML classifier, indicating a high likelihood of malicious intent. It contains an embedded URI pointing to 'https://jottigo.ru/123?utm_term=adjective+clause+worksheet+with+answers+pdf', which is likely used to deliver a malicious payload or conduct phishing. The document body, though heavily obfuscated, suggests a lure related to an 'adjective clause worksheet'. No scripts were extracted, but the presence of external URIs and the overall detection profile strongly suggest a phishing or malware distribution attack.

External URI info PDF_URIPDF contains an external URL action
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe 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_URLOne 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.URL https://jottigo.ru/123?utm_term=adjective+clause+worksheet+with+answers+pdf PDF link annotation
