T1204.002 Malicious Link
The PDF contains a critical heuristic firing for a malicious redirector link, which is also present in the document body. This link is presented as a lure related to 'Honkai Impact 3' game guides. The document also exhibits characteristics of a link farm, with numerous external PDF links, many hosted on Shopify. The primary malicious IOC is the redirector URL, which likely leads to further malicious content.
