KUALA LUMPUR, Dec 31 — Malaysians have been hit with yet another data breach. This time involving a banking institution, multimedia and broadcast agency and a government electoral agency where millions of personal information were said to have been sold online.

Such incidents have become increasingly rampant in the last two years.

Here Malay Mail lists some of the major data breaches that have happened in 2021 that continues to test the fragility of the nation’s cybersecurity even as the nation seeks to embrace 5G broadband network.


December 30 – Communications and Digital Minister Fahmi Fadzil has put two agencies on the tail of the latest data leak allegation involving some 13 million account holders from Malaysia’s largest bank Maybank, the EC and satellite broadcaster Astro.

The stolen information was posted on a popular online database marketplace where the seller asked interested parties to message them directly through Telegram or use the forum’s direct messaging features to complete the sale.

Lowyat.net reported that a separate listing also existed on the same day where the seller said they had personal database of internet provider Unifi's mobile customers. The seller was asking for US$850 (RM3,752) for the sale.

These contain the government employee’s MyKad number, rank, department, payslip numbers, email address and mobile phone number.

Batik Air acknowledged the issue in a press statement and disclosed that two former employees of its eCommerce partner GoQuo (M) Sdn Bhd in their development centre in India were involved.

Facebook said the leak was old data that was previously reported in 2019 and they had fixed the issue but the data here was leaked for free meaning the information can still be exploited by crude marketers, scammers, and hackers according to Gal.
