  • 11. Some facts on hacking• The Information Security Advisory Group estimates that world-wide there are now some 100,000 hackers or crackers (as they prefer to describe themselves).• Hackers have developed a program called ―The Backdoor‖ which provides them access to systems running Microsoft Windows.• Company computer systems are usually more difficult to hack because they employ protective arrangements such as firewalls.• The most infamous group of hackers – operating since 1994 – is an American team which calls itself ―The Cult of the Dead Cow‖ (CDC).• hacking incidents of recent times occurred in February 2000 when distributed ‗denial of service‘ attacks brought down the sites of Yahoo!, CNN, eBay,, Amazon, E*Trade, Datek & ZDNet.• hacking into 92 computer networks operated by NASA and the US military (including two break-ins at the Pentagon).• Western Union closed its web site for five days in September 2001 after a security breach saw hackers access 15,000 records containing credit and debit card details.
