Electronics Forum / Electronics / March 2010Energizer USB Duo battery charger hides a Trojan
Energizer USB Duo battery charger hides a Trojan March 9, 2010 by Lin Edwards (PhysOrg.com) -- The Energizer Duo USB battery charger has been hiding a backdoor Trojan in its software that affects computers using Windows. According to Symantec the Trojan has probably been there since 10th May 2007. Energizer has now taken the software for the model CHUSB charger off the market and removed the site from which it could be downloaded, and the company is asking customers who downloaded the Windows version to uninstall it. There are easy steps to fight the Trojan in affected machines, and Macintosh users are not affected. http://www.physorg.com/news187335556.html Cheers Don...

Makes you wonder, if Symantec said the Trojan has probably been there since 10th May 2007, then why one of those customers that run virus scanners, didn't report it to Energizer when they found it. And if they did, why something wasn't done about it in 2007. I saw them on the shelf recently and thought, I must get one of those. Much better than carrying an ac charger around with my netbook gear. Cheers Don...

Yeah. I was just thinking the other day: what can I do in addition to what I'm doing now to burn out those 500ma usb ports. Maybe I can look around for a USB toaster oven. Until I find one of those, the energizer battery charger is perfect! > And *none* of the users who own this device have *ever* run > a virus scanner?? *Surely* this trojan didn't actually do anything. If it started calling out on port 7777 someone would have noticed. >> And *none* of the users who own this device have *ever* run >> a virus scanner?? > > *Surely* this trojan didn't actually do anything. If it started calling out > on port 7777 someone would have noticed. How do you know it calls *out* and doesn't just open 7777 and *wait* for an incoming connection? Regardless, a virus scan would/should have noticed the payload. > How do you know it calls *out* and doesn't just open 7777 and > *wait* for an incoming connection? Possibly but considering even basic home routers have nat these days it wouldn't be very effective. So pretty much it would do nothing. > Regardless, a virus scan would/should have noticed the payload. Why? Unless it is a know virus it's unlikely to get picked up. >> How do you know it calls *out* and doesn't just open 7777 and >> *wait* for an incoming connection?

No one ever ran TCPview? >>> How do you know it calls *out* and doesn't just open 7777 and >>> *wait* for an incoming connection?

No, but I ran Topview once... >>>> How do you know it calls *out* and doesn't just open 7777 and >>>> *wait* for an incoming connection?

Jeeze you're old :) Most people did only run it once. >> Energizer USB Duo battery charger hides a Trojan March 9, 2010 by Lin > And *none* of the users who own this device have *ever* run a virus > scanner?? A virus scanner only detects the viruses that match a known signature, or which do something that it knows about. If the malware is stealthy enough it won't be detected. |
