These details are usually skimmed online by web-based keyloggers which can steal details from a browser as a customer types them into their computer. 

This is one of two major ways criminals are stealing credit card details, with the other involving hacking a point-of-sale machine in a brick-and-mortar store. 

RMIT credit card fraud expert Asha Rao said the best way to prevent a person from stealing credit card details online was to install anti-virus software.

‘Usually [when details are] stolen on websites it’s done while you’re online shopping,’ the associate professor told Daily Mail Australia.

‘If the website you are using has been compromised then it is when the CVV number would get stolen.

WHAT IS A WEB-BASED KEYLOGGER?

  • A web-based keylogger captures a person’s key strokes on a keyboard or pinpad
  • It recognises the key pressed and sends off that information to the person harvesting the details
  • A web-based keylogger can find its way onto a website through malware that is installed in many ways
  • These include clicking on a phishing link in emails or being infected with viruses or worms

‘Often what happens if you have a good anti-virus engine on your computer it should be able to tell you that the website has been compromised.’

Assoc prof Rao said the anti-virus program does not even have to be an expensive one.

‘There are good free anti-virus programs like Avast and AVG,’ she said.

‘You should have one on your mobile phone as well. Install it on whatever smart device you have that you do banking or shopping on, so it protects you while browsing.

‘Sometimes [the browser] takes forever to load, but that’s your anti-virus checking to see if the website is safe. If you are you looking for more about cvv shop look into our web page. ‘ 

Assoc Prof Rao also warned people against photocopying their credit cards for sellers and to look into a company before buying from them.

‘If I find a product at a particular company, I usually go onto to forums and type in that company to see if there is anything negative about it,’ she said.

‘Whether you’re buying something for $400 or $4,000, you should be checking.’

Assoc Prof Rao told people to watch out for scams set up to compromise your mobile phone.

‘For example, I was getting missed calls. [The phone] would ring one or two times,’ she said.

‘I just went online and went onto Google and typed the number in and it said there was a problem with this number.

‘So they’re hoping you call them back… to compromise your mobile phone, to get credit card details out of your phone if it’s stored in there.

‘If it’s an unknown number you don’t know, they can call you back.’
