A new keylogging trojan is racing around the world.

It is a variant of the Keylog-sters trojan that appeared almost a year ago and has been classified as high risk by security company PC Tools.

It captures screenshots of Web pages with login fields such as usernames and passwords, records the stolen data into a text file and uploads it to a private FTP server ..
"This is a regular keylogging trojan, but we have not seen one as widespread as this," said a company spokeswoman. "So far there have only been a few hundred cases in Australia, but thousands in the US and UK and other countries."

Top banks, mobile phone companies, and airlines are among those already affected in over 50 countries, including Australia. A large part of the problem with keylogging trojans is that desktop users receive no obvious indicators that they have been affected, leaving many unaware of the potential security breach.
