Stock exchanges in both the US and UK have fallen victim to cyber attacks in the last year, The Times newspaper has reported.
The newspaper claims that both the London Stock Exchange and an unnamed exchange in the US have sought the advice of security companies following separate attacks. The Times reports the US exchange traced one of the breaches back to Russia.
"Make no mistake, the UK’s critical infrastructure is under attack," an anonymous cyber security expert told the newspaper. "The threat is advanced and persistent."
Securities exchanges appear to be attracting the attention of cyber criminals recently. In January 2011, the European Union’s carbon trading market, which allows organisations to buy and sell carbon quotas, was temporarily suspended following a series of cyber security breaches. It was reported that hackers stole €7 million in carbon credits from accounts in the Czech Republic.
