2010 saw a sharp increase in the number of cyber attacks on Indian websites. According to Indian Computer Emergency Response Team, the defacement of websites with India specific domain ‘.in’ tripled in 2010. 8,864 websites with domain name ‘in’ were defaced in 2010 (January to November period) as compared to around 3,000 in the same period in 2009. Analysts say the rise in these incidents is because of poor security mechanisms adopted by individuals and small traders. In December, the website of Central Bureau of Investigation was hacked by Pakistani hackers.
