The E*Trade outage experienced by ANZ during the Christmas period has had a flow-on effect to St George's online-trading service, Directshares.
ANZ recently confirmed that its trading platform had come under a distributed denial of service (DDoS) attack during the festive season. As St George's Directshares platform is provided by E*Trade, its overseas customers were also affected by the outage.
E*Trade, ANZ and St George have not been able to determine who is behind the attack or its motivation, but St George has now confirmed that the overseas traffic block was put in place as this was where the attacks were coming from.
St George estimates that potentially affected overseas customers would have represented less than 1 per cent of its customer base.
Westpac, which merged with St George in December 2008, runs its own trading platform, and was not affected.
