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

The PDF file contains a large number of external links, with a specific heuristic firing for a 'PDF_SEO_LINK_FARM'. One of the primary URLs, http://raisengine.com/ZG93bmxvYWR8dFAxWTNBeWIzeDhNVFkxTnpFNE5qazFOWHg4TWpVNE4zeDhLRTBwSUVobGNtOXJkU0JiUm1GemRDQkhSVTVk?enthuse=hypertension=pitcher=littoral=dXNiIGRpc2sgc3RvcmFnZSBmb3JtYXQgdG9vbCBwcm8gY3JhY2sdXN, appears to be a malicious download lure. The presence of numerous links suggests an attempt to distribute malware or redirect users to malicious sites.
