In addition to students writing computer viruses and cybercriminals developing malicious software for personal gain, there are also threats from ‘grey business’ operations that undertake activities that are on the edge of – or just beyond – what’s legal. These businesses seek to generate revenues from a range of activities, such as:
Generally, these grey market businesses will use hacker program techniques in order to access the user’s computer – without the user’s knowledge – and to resist the actions of antivirus programs.
Special advertising components penetrate the user’s computer, and then download and display adverts – usually without the user knowing that any unauthorised software has been downloaded onto their computer. Often the pop-up adverts will only appear when the user has opened their Internet browser. In this way, the victim is likely to think that the pop-ups are just normal adverts that appear on standard web pages.
Legally distributed adware is often included as part of downloads of freeware or shareware applications. Although it may be possible to uninstall the adware element, some freeware and shareware programs will cease to operate correctly if the associated adware is removed.
The user is persuaded to download a fake antivirus or anti-spyware program. The fake program then states that spyware or a computer virus has been detected on the user’s machine. In reality, the program has not attempted to detect any cyber threats – and usually does not have any ability to detect threats. However, the program offers to treat the infection – in exchange for payment from the user.
In some cases, software may be installed – without having been authorised by the user – which then tries to persuade the user to visit a website that can only be accessed in exchange for a payment.
