TA14-300A: Phishing Campaign Linked with “Dyre” Banking Malware
10/27/2014 12:10 PM EDT
Original release date: October 27, 2014
Systems Affected: Microsoft Windows
Since mid-October 2014, a phishing campaign has targeted a wide variety of recipients while employing the Dyre/Dyreza banking malware. Elements of
this phishing campaign vary from target to target including senders, attachments, exploits, themes, and payload(s). Although this campaign uses
various tactics, the actor’s intent is to entice recipients into opening attachments and downloading malware.
The Dyre banking malware specifically targets sensitive user account credentials. The malware has the ability to capture user login information and
send the captured data to malicious actors. Phishing emails used in this campaign often contain a weaponized PDF attachment which attempts to
exploit vulnerabilities found in unpatched versions of Adobe Reader. After successful exploitation, a user's system will download Dyre banking
malware. All of the major anti-virus vendors have successfully detected this malware prior to the release of this alert.
