The Indian cyberspace is under attack and is being increasingly targeted by hackers and cyber criminals from neighbouring countries.

ICERT (Indian Computer Emergency Response Team) statistics show a rise in defacement cases. In January, 466 cases were reported whereas in January 2008 the number was 81.

Defacement of a website means changing the original content on the website by editing or adding fake information about people, organisation, or issues.

"Defacement can lead to serious problems for an organisation or a government body owning a website," Vijay Mukhi of the Foundation for Information Security and Technology (FIST) said.

"If some fake information is added on a website, it can lead to huge monetary as well as other losses for the owner. Defacement can be done by hacking into a website or by using some flaws in the software."

The ICERT report has divided the cases of defacement into two sections -- defacement cases in TLD (Top Level Domain) websites and CCTLD (Country Code Top Level Domain). Websites that fall in the TLD category have extension codes such as com, org, net, and edu whereas CCTLD websites have extension codes such as in, ac.in, gov.in, or edu.in.

"Cases reported to ICERT deal with mostly government websites that have been defaced," a cyber crime expert said. "On most occasions, the person defacing the website is traced to foreign countries. This makes it difficult to take any action against them."

Mukhi said several cases of defacement were not reported to ICERT. "This is another reason why no action can be taken against culprits," he said. "People should register complaints. One should keep upgrading the operating and other softwares to prevent websites being defaced."
