T1566.001 Spearphishing Attachment
T1059.007 JavaScript
This PDF file was flagged as malicious by a machine learning classifier and ClamAV, indicating a high likelihood of malicious intent. The document body, though heavily obfuscated, suggests a lure related to 'algebra 2 review packet answers'. The presence of multiple embedded URLs, with one pointing to 'golowaki.ru', strongly suggests an attempt to redirect the user to a phishing or malware distribution site. No scripts were extracted, but the PDF structure itself likely facilitates the redirection.

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://golowaki.ru/wix?keyword=algebra+2+review+packet+answers
