Conficker, also known as Downup or Downadup, is a new, incredibly sophisticated worm that came into existence on around October 2008, which has already infected millions of PCs around the world till this date.
Trust me, W32/Conficker is something you must be very alarmed about because this worm is a resilient virus with built-in p2p and digital code-signing technology capable of completely killing your Windows Security System, and guess what - this virus is due to be activated on April 1!
The programmer of this virus has repeatedly been updating its software and computer experts don’t have a single clue what the creator is going to execute with this virus on April 1; the virus is scheduled to contact a server for instructions exactly on April 1. Is Conficker an April Fool’s joke or an unthikable cyberworld disaster, no one knows for certain as of yet. Even computer experts around the world are finding it completely impossible to destroy it.
With an innovative built-in p2p capabilities, this worm can force its way to shared folders, printers, office network, USB flash, and hard drives pretty quickly, and can completely destroy your security software, disable windows update, Windows Defender, Windows Error Reporting tool, etc., leaving your computer open to any attacks. Plus this worm uses a sophesticated RPC request and can execute codes on the targeted computer. Spooky, isn’t it?
Speculation about Conficker’s purpose ranges from the benign — an April Fool’s Day prank — to far darker notions. One likely possibility is that the program will be used in the “rent-a-computer-crook” business.
