There's been a lot of talk about how Conficker is going to create havoc on April 1. Conficker, formally named W32/Conficker.worm, began infecting systems at the end of 2008 by exploiting a vulnerability in Microsoft Windows. Since then McAfee has seen two more variants of this worm and many binaries Â– files ready to load into memory and execute Â– that carry the wormÂ’s malicious payload. Conficker.C is the latest variant. Its Â“call-home protocolÂ” will change on Wednesday, April 1, and may entail an update with some as-yet unknown functionality.
McAfee already offers protection from the Conficker worm in its endpoint and network products, and Microsoft has issued a security patch for the vulnerability that the Conficker family has used to propagate. Yet many computer users continue to worry about infection.
