Online banking users are being warned of a new type of attack being dubbed the 'man-in-the-browser'. Using this tool, hackers can not only get access to your banking details, but they can obscure the real status of your account, showing you false figures after making withdrawals.
So what can users to to prevent this sort of thing from happening?
Keep your browser up to date
If you have Chrome, it will update automatically, but you may need to turn on automatic updating for Firefox or Internet Explorer using the help menu.
Call your bank if something doesn't seem right
If you are asked to enter your whole password instead of just parts, or if your transaction seems to be taking longer than usual, or you're worried about the figures in your statement, call your bank. Try to remember as many details as possible, such as the exact time this happened.
Remember, virus protection doesn't catch everything
Anti virus software focuses on checking a database of existing viruses, so new viruses do not get caught at first. Be wary if your machine starts slowing down dramatically or starts to exhibit strange behaviour. Windows users should look at using Microsoft Security Essentials, a free anti-virus program which updates itself regularly.
