MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of external links, many of which point to similarly structured URLs on different domains, suggesting a link farm for SEO manipulation or malware distribution. One of the extracted URLs, 'http://theelfbox.com/uploads/1/3/1/1/131164043/131164043.html#yi+4k+action+and+sports+camera+manual', is presented as a manual for a popular camera, likely a lure to entice users to click. No scripts were extracted from this sample.
