The compromised medical databases include personal information, MyKad numbers, mobile/work/home phone numbers, and work and residential addresses.

The website that reported the news is concerned that no remedial action has been taken by the service providers involved to protect the victims of the data breach.

“While it is the task of the authorities to narrow down the source of the breach, and ensure that a similar incident doesn’t happen again, the key to containing any more serious damage is protecting the individuals affected by the breach.” continues lowyat.net.

“We are urging the telco and MVNO companies mentioned above to alert and start immediately replacing the SIM cards of all affected customers, especially those who have not updated their SIM cards since 2014. While the leaked data alone isn’t sufficient to clone the SIM cards, the information available can be exploited to initiate multiple social engineering attacks against affected users.”
