Security company Arbor Networks is warning CIOs to keep up to date abreast of on the latest security attacks. Its latest worldwide infrastructure security report has found a 67 per cent rise in large attacks on websites and that smaller, more sophisticated attacks are becoming more difficult to stop.
The report includes responses from nearly 70 IP network operators in Asia Pacific, North America, South America and Europe.Australia and New Zealand country manager Nick Race says an important point from the report for CIOs is that 50 per cent of the time the attackers will try to dupe the end user.
“A site like Trade Me might be a target for extortion. We quite often find cyber criminals use attacks for blackmail. What our technology provides to businesses is clean internet pipes so they can guarantee they won’t be attacked and their online presence taken down by security vulnerabilities.”
Race is aware of examples on overseas trading sites such as e-bay. "Any form of auction site or consumer- based trading site is one of the targets whether that be from disgruntled users or whoever. Financial institutions are also a favourite target.”
Turning to sophisticated attacks, he says cache poisoning is a good example. "You try to access Trade Me and go on to what you think is the site, but you’ve actually been redirected to a site in Russia.”
He adds that New Zealand can provide an early warning system for time-based internet attacks. “The slammer worm started in Auckland about five years ago and spread out across the globe as it was set to go off at certain times.”
The report also notes that 26 per cent of botnets, or infected computers, are still the vehicle for delivering the largest problems to network operations.
“The sizes of botnets are rising as there are millions of compromised PCs associated with them. These can be focused on one poor individual so the volume becomes out of control quickly.”
