In less than four minutes, about RM5,000 disappeared from manager Yong Chee Seong's bank account after he was asked to update his online banking details in an e-mail he received on Tuesday, Kosmo! reported.

"The e-mail looked genuine and I was told to change my bank account password for safety reasons and to avoid being cheated by cyber frauds," said the 30-year-old.

Yong said he did not suspect anything amiss until he received an SMS from the bank, informing him that a total of RM4,935 had been transferred out of his account.

When contacted, the bank said its policy did not require account holders to change their personal information via e-mail.

Yong made a police report at the Sea Park police station in Petaling Jaya the same day.
