Trojan.Hydraq detection and naming


Ok, it is not really a big deal, the trojan was in the wild since at least 2006 and Symantec just added a better name for it. It was discovered not on January 11, 2010 but much earlier. I like Hydraq better than just Trojan Horse, really. Why Hydraq? What prompted the name, I wonder.


Here is a Symantec blog entry linking Hydraq to attacks on Google Hydraq - An Attack of Mythical Proportions. 


Update Jan. 20, 2010 Please read more about IExplorer 0day CVE-2010-0249 – Exploit-Comele / Hydraq / Aurora  on from Extraexploit.blogspot.com here and here 

  
Update Jan 24, 2010  Download Hydraq
 As you see, Hydraq is well researched (http://blog.threatexpert.com/2010/01/trojanhydraq-part-ii.html) and most AV products detect the key files. I can provide the following files for antivirus and IT security companies/researchers.

c_1758.nls (ba3545841d8a40ed8493e22c0e70a72c)- copy of the trojan
Acelpvc.dll (4A47404FC21FFF4A1BC492F9CD23139C)- helper file
VedioDriver.dll (467EEF090DEB3517F05A48310FCFD4EE)- helper file
