We were chatting in my local the other day about computer security. There had been numerous reports of viruses, worms, spyware and other malware (Malicious Software) on the news, in fact there have been reports of these almost every week now. It has gotten so bad that a US Government agency (US-CERT) has advised against the use of Internet Explorer (IE) More here
My friend, being a typical bloke, wanted to change the subject to more bloke-like things like football and/or women. I guess he, like most people would regard his PC as just a souped-up television and would regard a virus infection as just a minor annoyance with no serious consequences. Well, here is a list of consequences a computer virus can be responsible for :-
1. Slow down your computer or cause it to crash.
2. Infect other computers on the Internet or your network.
3. Use your PC to launch DDoS (Distributed Denial of Service) attacks on other web sites causing the site to crash and the owner to lose money.
4. Use your PC to send out yet more
spam.
5. Transmit your personal details held on your PC to hackers to use in identity theft. They can then use your details to take out loans in YOUR name.
6. Keystroke logging to discover your passwords and use those to access your bank account.
7. Use your PC to host child pornography web-sites. Could you explain how those evil photos got on your PC to your wife or the police ?
If that does not make you worried, it should. Many ISPs (Internet Service Providers) are becoming under pressure to block infected computers from their networks until they have been 'cleansed'.
Back in the pub. ".. and in any case, I haven't got any money for these hackers to steal anyway !!", he finished, completely missing the point. I tried to explain to him that if someone stole his identity, they could get many loans in HIS name and go on a massive shopping spree " he might not have much money but, he would have even less by the time the banks could close his account. And there is a real possibility that his credit rating would permanently damaged.
Take care out there
