FIN4

1 min read

On December 1, 2014, a blog regarding activity by a threat actor classified as “FIN4” was published by the Wall Street Journal. This article describes an active targeted phishing campaign with a focus specifically targeted at the emails of C-level executives, legal counsels, regulatory, risk, and compliance personnel, and other individuals who discuss confidentially and potentially market affecting matters.

What We Know

The technique uses spear phishing emails to gather credentials from users and return them back to the Command and Control servers (CnC) where the login credentials are then used to log into the users' webmail remotely through TOR to escalate the attack. This threat activity was previously alerted on by eSentire in a communication sent to our clients and posted to our website on November 11, 2013. At that time eSentire began blocking these attacks for our clients proactively within the Asset Manager Protect Service (AMP) and have continued to watch for these indicators since.
