More security news today, healthcare workers be aware...keep up to date with your security updates and be sure to report anything strange to your IT department/agency.  While at work refrain from going to websites you don't know...it used to be just email attachments, but now just clicking on a link in an unfamiliar websites can do you in...BD 

BOSTON (Reuters) - A few weeks ago Candace Locklear's office computer quietly started sending out dozens of instant messages with photos attached that were infected with malicious software.

She was sitting at her desk, with no sign that the messaging software was active. By the time she figured out what was going on, several friends and colleagues had opened the attachments and infected their computers. It took eight hours for a technician to clean up her computer. But because the malicious software worked so secretly, she's still not convinced that all's clear.

"You won't know you are infected until one day your ISP turns you off or restricts access or money starts disappearing from your bank account," said Adam O'Donnell, a senior research scientist with Cloudmark, which sells anti-spam software.

Some are keyloggers, recording every key stroke that the user enters -- sending valuable bank account information, passwords and credit card numbers to hackers. And other malware programs turn PCs into " zombies," literally giving hackers full control over the machine. The zombies can be instructed to act as servers, sending out tens of thousands of spam emails promoting counterfeit medications, luxury watches or penny stocks without the PC owner ever knowing about it. The computer that controls the zombies -- known as the command and control center -- is able to change the text of the spam depending on what his or her customer wants to sell.
