A new virus is in town and this time it’s got a specific target: online banking customers. Known as the Clampi virus, it represents a major threat to those that bank via the internet.

The Clampi virus is whats known as a Trojan, mainly because of its ability to secretly penetrate a computer, wait patiently until needed, then report bank to its creator, or indeed, take instructions from its creator.

And the cyber criminals behind the Clampi virus have on objective in mind: to steal personal details from a computer.

It is spreading rapidly through the US and UK, infecting computers and then waiting until the time is right to strike. When the user of the computer logs into their bank account for example, the Clampi virus makes a note of the username, password and other pertinent details, which are then sent back to the hackers.

These details are then used by the hackers to enter financial sites and either transfer money, change account details, or set-up frauds.

It is believed that people behind the Clampi virus monitor in the region of 5,000 financial websites and amongst these are most of the UK high street banks. But it’s not just banks; sites run by mortgage lenders, online casinos, shopping operations and email providers are also targeted.

In the US the Clampi virus has already been responsible for thefts of thousands of dollars and its been reported that many schools and businesses have been affected.

The Clampi virus is not new, having been around since 2005, but computer security experts think that this is a new, more virulent strain and poses a major threat to online banking. And they believe it attacks in waves, the UK banks being a major target.

They are unsure as to the true extent of the damage caused in the UK, especially given the covert nature of Clampi’s operation, but think that over 1,000 computers have already been affected. And those running Microsoft Windows operating systems seem to be more vulnerable than most.

And the computer security experts are warning again that people should remain vigilant at all times, reiterating the fact the such viruses are usually distributed embedded in emails, website downloads and instant messages, as attachments and links. They urge anyone not to open links, or attachments, from sources they cannot trust.

What’s more, they remind computer users that they should never send emails, or surf the web, without an up-to-date anti-virus software application on their machines.
