Most people are familiar with hackers, the deviant computer programmers and users that try to gain nefarious access to computer systems for their own personal gain. Hackers have warned that high street retail chains like Tesco and Marks & Spencer could be the next target.
The hackers say that attacks such as those used against the government of Estonia that shut down various websites for banks, governments and political parties could be used against retail chains.
The Estonia attacks bought the economy of the country to its knees according to BBC News. "At the moment Chief Executives are only interested in the bottom line. But remember - if tesco.com goes down, that's a lot of shopping."
