T1566.002 Spearphishing Attachment
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, 'https://ttraff.cc/wb?keyword=gigabyte%20ga-970a-d3%20manual', is designed to lure users into clicking it by appearing to offer a relevant manual. The presence of numerous other external PDF links, many hosted on suspicious domains, further indicates a malicious intent, likely to distribute further malware or engage in SEO-based traffic generation for malicious sites.
