Analysis Summary
Advanced techniques, tools and procedures (TTPs) have been observed being used by a new threat actor in order to bypass cyber controls used by many corporations. This threat actor is targeting financial organizations like banks with more sophisticated tools, complex obfuscation and customization. The attack begins with a phishing email containing a malicious link that downloads a word document. Examples of URLs created by the threat actor include hxxps://socgen-cert[.]com/documents/REQ-193.doc and hxxps://ing[]cert[.]com/documents/PO-2815.doc. The documents were also seen on amf-fr[.]org, alerts-swift[.]com, and socgencompliance[.]com.
