Be very careful of incoming email labeled “Wanna Rumble?” it contains a new strain on W32.Yaha (P). Over the last few days I have seen these Virus suddenly start coming in repeatedly through out the day. Here’s what Symantec says about the Yaha virus:
The W32.Yaha.P@mm worm is a variant of W32.Yaha.L@mm. This variant of the worm terminates some antivirus and firewall processes.
W32.Yaha.P@mm uses its own SMTP engine to email itself to all the contacts in the Windows Address Book, MSN Messenger, .NET Messenger, Yahoo Pager, and in all the files whose extensions contain the letters HT. The email message has a randomly chosen subject line, message, and attachment. The attachment will have either a .exe or .scr file extension.
This threat is written in the Microsoft C++ language and is compressed with UPX. The uncompressed size is about 45 KB.
