MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file was flagged by multiple heuristics, including a critical finding for a large number of embedded external PDF links, suggesting a link farm. The ML classifier also strongly indicated maliciousness. The embedded URLs, such as http://christine-simmons.com/uploads/1/3/0/7/130776147/vikezubuwe.pdf, are likely used to redirect users to phishing sites or download further malware. The document body contains garbled text and some of the same URLs, reinforcing the malicious intent.
