Mitglieder puts system under complete control of attacker by opening 'backdoor' on a port using which attacker can update Trojan, to stay a step ahead of attempts to remove it, download and execute files, initiate an SMTP server to relay spam, execute files on infected computer and download and execute files via an URL. "This is what makes it scary," say Aarti, Assistant Manager, QA, MicroWorld Technologies. "The fact that system can now be used as a remote controlled 'soldier' (bot) in an army (botnet) of similarly compromised machines to launch criminally motivated attacks, causing harm to Internet users."
Botnets thus formed can among other things, use your machine to launch Distributed Denial of service attacks which overload servers, making them crash, to send out spam, spread new Malware, plant Keylogger to retrieve your personal information like identity, passwords, account numbers etc., install Spyware, manipulate online polls/games, abuse programs like Google AdSense to cheat advertisers of revenue, and install Advertisement Addons for financial gain as in fake websites advertising services that don't exist.
"Botnets can even encompass over 50,000 host machines. The potential for mischief is huge," reflects Govind Rammurthy. "Such a three-pronged Trojan attack where attackers change their virus code and release viruses quickly to bypass virus signature scanners, then disable network access to deny user link-ups to anti-virus and Microsoft Windows Update site for protection has huge significance for virus-signature based protection. It is a sign of things to come," he says, remembering scramble at MicroWorld labs to update their products to detect and remove three Trojans.
Anti-virus updates for three-pronged Trojan threat are available at MicroWorld Technologies site. Maybe time for worrying about some pimply teenager turning out malicious code because they have nothing better to do on a nice sunny morning, is over. The world could be facing a determined organized crime syndicate who'll stop at nothing to get what they want - information precious to you.
