Cyber crimes reported in India rose 19 times over the last 10 years (2005 to 2014), from 481 in 2005 to 9,622 in 2014. India is now ranked third - after the US and China - as a source of "malicious activity" on the internet, second as a source of "malicious code" and fourth and eight as a source or origin for web attacks and network attacks.

Under the IT Act, the most - 5,548 cases - reported were computer-related offences, of which 4,192 were under Section 66A, which allows for jail terms up to two-three years for sending "offensive messages through communication service" and related offences.
Section 66A of the IT Act was struck down by the Supreme Court in March 2015, saying: "Such a law hit at the root of liberty and freedom of expression, the two cardinal pillars of democracy."
