Malaysia could once again be faced with a data security scare after CIMB Group revealed that some magnetic tapes containing backup customer data had been lost in transit.
The group said on Monday (Nov 13) that there was no evidence any of the data on those tapes had been compromised.
It is understood that the lost data included customer information from CIMB Bank and its subsidiaries.
The nation’s central bank Bank Negara Malaysia confirmed that it was aware of the incident.
In a statement, Bank Negara said it was “assured by CIMB Bank that necessary precautionary measures and mitigation actions have been taken to manage any possible negative impact arising from the loss of the tapes”.
According to CIMB, the tapes do not contain any authentication data such as pin numbers, passwords or credit card security numbers.
The group also said that it had heightened security measures, and have suspended some of its call centre services.
Meanwhile, Singapore’s Monetary Authority of Singapore (MAS) said that CIMB’s Singapore branch has been told to “ascertain the extent of the data loss and to take necessary measures to protect its customers,” The Straits Times reported.
An MAS spokesperson told the local daily that CIMB Singapore customers should exercise vigilance and closely monitor SMS and other alerts from their financial services providers.
Malaysia had in October suffered a data nightmare when reports of the country’s largest-ever data breach surfaced.
Malaysian authorities said then that it would be looking into a possible data leak affecting 46.2 million postpaid and prepaid subscribers in Malaysia.
