If I had an internet banking account with DBS, given its track record in IT , I would be afraid, very afraid. Read how smart hackers can be: http://www.bbc.co.uk/news/technology-16812064
If you bank with HSBC, Citi, OCBC or UOB, relax. These banks have gd IT track records here, even though HSBC and Citi have a lot of FTs from India, more possibly than DBS. UOB and OCBC: true blue S’poreans in their IT departments (OK, more than in DBS).
If I had shares in DBS, I’d be afraid that another security problem could cause very serious damage to DBS’ reputation and pockets.
