The Stock Exchange of Thailand (SET) has revealed that its Web site was hit by a distributed denial of service (DDoS) attack on Monday. The exchange says it has temporarily redirected access to the site from an alternative international network and that trading was not disrupted by the attack.

The hit on the Thai bourse follows a spate of similar malicious take-downs of other exchange sites, including Bursa Malaysia, Nasdaq OMX, Bats Trading and the Chicago Board Options Exchange.

Early indications suggest that the US exchanges may have incurred the ire of the Anonymous hacking collective in support of the Occupy protest movements.

The perpetrators of the SE Asian attacks have yet to be identified.
