T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF document contains a large number of external links, many of which point to other PDF files or potentially malicious content. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass of external links, suggesting a tactic to distribute malware or phishing content. The primary IOC is the URL http://evacdir.com/chemises/nishayam/hexaniacinate/pleuritis/cumbria?ZG93bmxvYWR8SGsxWWpJM2VIeDhNVFkxTnpFNE5qazFOWHg4TWpVNE4zeDhLRTBwSUVobGNtOXJkU0JiUm1GemRDQkhSVTVk=prfree&S3JhbnRpIDE5ODEgRHZEUmlwIHgyNjQgQUMgMyBNNzc3IE0yVHYS3J=, which is likely used to host or redirect to a malicious payload.
