Home PCs under attack from hackers more than 50 times a night, suggests 大象传媒 News Website experiment

Home PCs could be under attack from hackers more than 50 times a night, suggests a 大象传媒 News Website experiment.
听
The 大象传媒 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.
听
Every single time the honeypot was put online it was attacked.
听
In one of the busiest nights of malicious online activity, the computer was attacked 53 times:
听
 one 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;
听
two "port scans" which look for weak spots in Windows software - reconnaissance by hackers seeking new victims;
听
11 attacks by the 'Blaster' worm - success would have rendered the machine unusable;
听
three attacks by the 'Slammer' worm - success would have left machine crippled and prone to crashing;
听
36 fake security announcements/adverts for fake security software posing as warnings. Reacting to these could leave a PC clogged with spyware.
听
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.
听
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.
听
The experiment demonstrates the vulnerability of unprotected home PCs to malicious hackers.
听
According to Symantec, 86% of all targeted attacks on computers are aimed at home users.
听
There are an estimated 200,000 malicious programs in existence.
听
Starting today (Monday 9 October 2006), the 大象传媒 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.
听
As part of the 大象传媒 News Website's Cracking Hi-Tech Crime specials the 大象传媒 also talks to the hi-tech criminals behind the viruses, 'phishing' emails and malicious programs putting home PCs at risk.
听
One hacker the 大象传媒 spoke to claims to have earned $10,000 a day from computer crime.
听
Another says that they can hack into many online shops within three to four hours and sell the data on for anything between $100 and $500.
听
Unconcerned about the risk of arrest the hacker adds: "How can a cop catch me? Catch me if they can!"

Notes to Editors
听
In the 大象传媒's honeypot PC experiment none of the attacks was solicited. The computer was simply put online and the attacks recorded over a month-long period.
听
The 大象传媒's honeypot PC recorded around 30 attacks in each seven-hour overnight test period (midnight-7.00am), with attacks occurring around every 12 to 15 minutes.
听
Most were 'nuisance' attacks - fake security warnings or attempts to trick people into thinking their machine had been hijacked.
听
According to the Get Safe Online campaign, which launches in the same week as the 大象传媒 News Website's special week of hi-tech crime features, 52% of Britons use online banking.
听
In 2005 UK losses to 'phishing' hit 拢23m - almost double that lost in 2004.
听
PC penetration in the UK has hit 57% of households, of which 69% are broadband users.
