T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a critical heuristic firing for a malicious redirector link, which is further supported by the presence of numerous other PDF links, many hosted on Shopify. The document body, though partially corrupted, contains text related to a 'Biblia de estudio reina valera pdf gratis' and the redirector URL also contains a similar keyword, indicating a lure for free content. The primary malicious URL is https://ttraff.cc/pify?keyword=biblia+de+estudio+reina+valera+pdf+gratis, which likely leads to further malicious content.
