London: A British cyber security expert has warned that terrorists could use a "blended attack" to hit both physical targets and disrupt cyber systems simultaneously during the 2012 London Olympics.
Professor Peter Sommer, of the London School of Economics, warned that computer security would be extremely important during the Games.
"There is what`s called a `blended attack`, so there is a physical attack, but it`s made easier because someone is disrupting cyber systems at the same time, so that is the sort of scenario that people have got to worry about," Sommer was quoted, as saying.
The warning propels the threat highlighted by former Home Secretary David Blunkett, who had warned the Gordon Brown Government that the Games could face a cyber attack.
Blunkett had earlier stressed that terrorists could use sophisticated hacking to trigger the "complete meltdown" of computer and communications systems or disrupt ticketing, accommodation and transport arrangements.
The Labour MP for Sheffield Brightside had highlighted that such an attack would be "economically and commercially devastating".
He had also urged for a coordinated approach between the government and the security experts to ensure a safe and secure Games.
