Damballa Principal Scientist Presents New Technique For Detecting DGA-Based Malware

Pleiades detects Domain Generation Algorithm-based botnets

ATLANTA—August 10, 2012—Damballa Inc., the company transforming the fight against cyber threats, today announced that Principal Scientist Dr. Manos Antonakakis will be a featured speaker at the 21st Annual USENIX Security Symposium, Friday, August 10. This is the third consecutive year that Dr. Antonakakis has had research accepted and presented at the prestigious conference.

Dr. Antonakakis’s presentation, “From Throw-Away Traffic to Bots: Detecting the Rise of DGA-Based Malware,” is based on a paper written by researchers at Damballa Labs, Georgia Institute of Technology and the University of Georgia. The paper can be viewed here: https://www.usenix.org/conference/usenixsecurity12/throw-away-traffic-bots-detecting-rise-dga-based-malware.

The session will introduce a new cyber threat detection technique named Pleiades, which is designed to detect criminal malware threats that use domain generation algorithm (DGA)-based techniques to establish command-and-control communications and completely evade detection by blacklists and signature-based systems. The Pleiades innovation, which is already deployed in Damballa customer installations, also eliminates the need to reverse engineer malware in an attempt to ‘decode’ the DGAs, a method which is often unsuccessful or unreliable. The new technology recently enabled Damballa customers to detect the Flashback malware, which ultimately infected more than 600,000 Macintosh devices, weeks before the malware was first discovered and announced by the security community.

Pleiades uses a combination of clustering and classification algorithms. The clustering algorithms cluster domains based on the similarity in the make-up of domain names, as well as the groups of end point devices that queried the domains. The classification algorithm is used to assign the generated clusters to models of known DGAs. If a cluster cannot be assigned to a known model, then a new model is produced, indicating a new DGA variant or family.

During the session, Dr. Antonakakis will report the discovery of twelve DGAs, half of which are variants of known malware DGAs, and the other half are new DGAs that have never before been reported.

This research follows closely a discovery which Damballa unveiled earlier this year on advanced evasion techniques using DGAs by six crimeware families to carry out global cyber attacks. Without having to reverse engineer malware or 'decode' the DGA algorithm, Damballa Labs automatically detected and modeled DGA behavior by using this patent-pending machine learning technology. The report is titled “DGAs in the Hands of Cyber-Criminals - Examining the State of the Art in Malware Evasion Techniques” and can be viewed here:

CVE-2013-6117
Published: 2014-07-11
Dahua DVR 2.608.0000.0 and 2.608.GV00.0 allows remote attackers to bypass authentication and obtain sensitive information including user credentials, change user passwords, clear log files, and perform other actions via a request to TCP port 37777.

CVE-2014-0174
Published: 2014-07-11
Cumin (aka MRG Management Console), as used in Red Hat Enterprise MRG 2.5, does not include the HTTPOnly flag in a Set-Cookie header for the session cookie, which makes it easier for remote attackers to obtain potentially sensitive information via script access to this cookie.

CVE-2014-3485
Published: 2014-07-11
The REST API in the ovirt-engine in oVirt, as used in Red Hat Enterprise Virtualization (rhevm) 3.4, allows remote authenticated users to read arbitrary files and have other unspecified impact via unknown vectors, related to an XML External Entity (XXE) issue.

CVE-2014-3499
Published: 2014-07-11
Docker 1.0.0 uses world-readable and world-writable permissions on the management socket, which allows local users to gain privileges via unspecified vectors.

CVE-2014-3503
Published: 2014-07-11
Apache Syncope 1.1.x before 1.1.8 uses weak random values to generate passwords, which makes it easier for remote attackers to guess the password via a brute force attack.
