First Direct's Twitter account has been hacked by a spammer who used it to post a link to an adult sex site.
One Twitter user commenting on the attack, said, "I would be very interested in knowing how it happened. If it was just a guessable password, that is worrying in itself, anything more clever is even more worrying."
First Direct has been on Twitter since October 2009. According to the Financial Services blog, which focuses on European financial markets, First Direct has pioneered web 2.0 in online banking.
Twitter is among several endeavours into web 2.0 by First Direct. Last year, the bank launched a social media site to aggregate consumer opinions from eight million social media sites. The company uses the site to gain a better understanding of what people want and to improve customer service.
