MITRE ATT&CK

The PDF contains a large number of embedded external links, identified as a link farm, with the primary purpose of directing users to potentially malicious content. The document body, though heavily obfuscated, contains references to 'Adobe acrobat pro dc license not working', suggesting a lure to trick users into clicking on the provided links. The presence of numerous PDF links strongly indicates an attempt to distribute further malicious content or phishing pages.
