Over the past few years, India has witnessed a growing number of cyberassaults, with government departments, particularly defence establishments, coming under attack.

Last year, hacker group Anonymous carried out a series of Distributed Denial of Service (DDoS) attacks against a number of government websites, in retaliation against the alleged internet censorship.

Hackers from Algeria also carried out an attack on websites run by the DRDO, the Prime Minister's Office and various other government departments last year. A group called Pakistan Cyber Army had also hacked into several Indian websites.

"The threat landscape remains very threatening," said cyberlaw and cybersecurity expert Prashant Mali.

"India is awakening to the global threat of cyberwarfare now. Our cybersecurity is still ineffective as mass awakening towards it is missing or inadequate. Even though NTRO and DRDO are mandated with cyber offensive work, only time will show effectiveness of these organizations," Mali told IANS.

Usually, cyberattacks follow the same modus operandi. An email is sent to an individual, or small group, within an organization. Efforts are made to make the email look legitimate, that is, it will appear as though it was sent by somebody the recipient trusts and the content of the mail will often be related to the recipient's area of interest.
