According to a report by global anti-virus company Symantec, while 35 per cent of the infections were observed in the US, nearly 6 per cent of ZeroAccess infections were in India.
According to Symantec, the ZeroAccess botnet is one of the largest of its kind in existence. Over 1.9 million infected computers are observable on a given day (statistics from August 2013). The US has recorded the highest infection rate, at 35.1 per cent, and Japan is at second position with 9.3 per cent.
The cyber-security company said it had been grappling with the ZeroAccess botnet for some time now, getting some amount of success in tackling about half a million bots.
The situation in India does not seem to be getting any better, it would seem. In a related report in April this year, Symantec revealed that India had seen a 280 per cent increase in bot infections that was continuing to spread to a larger number of emerging cities in India.
“With the prevalence of such infections, it is not surprising that the country accounts for nearly 15 per cent of global bot-net spam, responsible for disseminating an estimated 280 million spam messages per day worldwide.”
In addition, the report had highlighted a 42 per cent surge during 2012 in global targeted attacks, as compared to the prior year. Designed to steal intellectual property, these targeted cyber espionage attacks, Symantec said, were increasingly hitting small businesses, which were the targets of 31 per cent of these attacks across the world. Small businesses are attractive targets themselves and a stepping stone to ultimately reaching larger companies.
Symantec said the ZeroAccess botnet especially used a peer-to-peer (P2P) command-and-control (C&C) communications architecture, which gave it a high degree of availability and redundancy. In the ZeroAccess botnet, each peer continuously connected with other peers to exchange peer lists and check for updated files, making it highly resistant to any takedown attempts.
