Is Downadup or Conficker Detected by the AV Engine on ScreenOS?



Article ID: KB13254 KB Last Updated: 31 Mar 2009Version: 3.0
Downadup, also known as Conficker (sometimes mis-spelled as Conflicker), is a worm that propagates on local and network drives by taking advantage of Microsoft Windows Server Service RPC Handling Remote Code Execution Vulnerability. 
Do Juniper firewalls with the proper AV license protect agains this malware?
The Downadup/Conflicker malware/worm (including the detection of the Net-Worm.Win32.Kido (conficker.c)) is included in the Juniper Full AV Database, supported on all SSG platforms with the av_v2 license key installed. 

It is also recommended, if you haven't already done so, to install the Microsoft patch MS08-067, which protects the server against the source of the malware/worm.

Note:  The AV engine will detect incoming signatures that match the conficker/downadup/kido worm, and will drop it. However, if a device currently is already infected with the conficker/downadup/kido worm, it will not be able to detect traffic as it goes outbound. In order to detect that, you need to purchase the IDP product, which has that ability.  For more information, refer to KB13762.
