Security breaches still occur

The Monetary Authority of Singapore (MAS) said there has been no evidence to date of a breach of payment security among banks in Singapore ("Security steps for credit cards robust: MAS"; last Thursday).

Recently, I received an SMS alert asking me to enter a one-time password (OTP) in order to complete a ยค613.62 (S$1,069) transaction.

As the transaction did not originate from me, I ignored the message. I presumed that the transaction was rejected.

But I was surprised to find the transaction charged to my account. I was also charged for 20 other unauthorised transactions (no OTP alerts were received for these).

The bank concerned subsequently reversed the charges.

Don't the above incidents constitute breaches of security?
