    Name of Checkfree trojan?

    Does anyone know the name of the trojan used in the Dec. 2nd DNS hijack of CheckFree?

    DNS wasn't really hijacked. They managed to obtain the username/password that allowed them to change the domain.

    They probably got those credentials with spear phishing.

    You sir are correct, poor wording on my part. Do you know what the name of the malware/trojan was? I need this info because I have to call customers who were affected by this. I am just wondering what McAfee or Norton would have called the software if detected.

    As I said, they probably used spear phishing, not a trojan or any other type of malware.

    No. The users that were directed to the site in the Ukraine, as opposed to the real checkfree site could have had their computers infected with malicious software. My question is what would a antivirus scanner identified the threat as? Most sources say the fake web server attempted to download a Trojan using an IE exploit. I want the name of the Trojan. That is my question here.

    According to CNET the name of the file was msn.exe.

    Ah.. Now I understand

    AFAIK they used an adobe acrobat exploit to install a keylogger. See http://www.securityfocus.com/bid/30035
    No names, so it's likely a custom build exploit.
