You Might Be Under Attack

Can the white hats stay ahead of the black hats? It doesn't seem so. It almost looks the black hats have become a criminal organization with vast resources and these attacks are not an attempt to prove it can be done but rather for financial gain and disruption of our economy. There are reports that there are something like 100 attacks a day by Chinese hackers. Does anyone think they could get away with this without support from their government. My advice is to keep you bank balance and credit card limit low.

Home computers targeted by hackers '50 times a day'

Risk: Home computers are a target for hackers

Home PCs could be under attack from hackers over 50 times a night, suggests a BBC News Website experiment.

The BBC News Website team set up a honeypot' PC – a computer that looks like a normal PC online but records everything that's done to it – in order to find out the dangers facing web users.

Every single time the 'honeypot' was put online it was attacked. In one of the busiest nights of malicious online activity, the computer was attacked 53 times:

• 1 hijack attempt. PC suffered buffer overflow attempt to subvert web server built into Microsoft Windows. A successful attack would hand over control of the machine to a hacker
• 2 "port scans" which look for weak spots in Windows software - reconnaissance by hackers seeking new victims.
• 11 attacks by the 'Blaster' worm - success would have rendered the machine unusable
• 3 attacks by the 'Slammer' worm - success would have left machine crippled and prone to crashing
• 36 fake security announcements/adverts for fake security software posing as warnings. Reacting to these could leave a PC clogged with spyware.

Over the course of the whole experiment, on average at least one attack an hour came from a dangerous computer bug with the ability to cripple an unprotected PC. And at least one attack per night was even more serious - an attempt to hijack the computer entirely – which could lead to the computer being turned into a 'zombie PC' and used to carry out criminal activity without the owner's knowledge.

The experiment demonstrates the vulnerability of unprotected home PCs to malicious hackers.

According to Symantec, 86 per cent of all targeted attacks on computers are aimed at home users. There are an estimated 200,000 malicious programs in existence.

Starting today, the BBC News Website is running a whole week of special features looking at the issue of hi-tech crime and giving people advice on they can stay safe online.

As part of the BBC News Website's 'Cracking Hi-Tech Crime[ specials the BBC also talks to the hi-tech criminals behind the viruses, 'phishing' e-mails and malicious programs putting home PCs at risk.

One hacker the BBC spoke to claims to have earned $10,000 a day from computer crime, another says that they can hack into many online shops within 3-4 hours and sell the data on for anything between $100-500. Unconcerned about the risk of arrest the hacker adds: "How can a cop catch me? Catch me if they can!"
