SYDNEY, June 26. /ITAR-TASS/. The main threat for organizers and participants of the upcoming G20 summit in Australia’s Brisbane will come from hackers, Australia Security Intelligence Organization (ASIO) director-general of ­security David Irvine said.

“I’m more concerned about… the threat of activists using cyber-means to disrupt the arrangements for the G20 meeting,” Irvine said. Hackers will most likely try to take out electricity systems and communications, he added.

 “Obviously, there are going to be very significant attempts to collect information relevant to G20,” Irvine noted. “That’s something that individual delegations and so on will have to handle their own way.”

The G20 summit will take place in Australia’s Brisbane on November 15-16. In A G20 meeting at the level of ministers is also planned for autumn, it will take place in Cairns.
