The breach was brought to attention by local tech news site Lowyat.net. In the article, it was said that the personal data of Malaysians from databases of online recruitment portals and medical associations have been leaked and sold online.

The tech news site also found out that mobile phone numbers and IC number addresses were advertised on forums.

MCMC and other government bodies took notice and investigations were promptly carried out.

Rozario added that not all information in the breach is useful for hackers. For instance, the IMEI numbers may be used for fraud, but most people would have changed their phones since 2014; making the number relatively useless for crime. The same goes for IMSI and SIM numbers.

According to one engineer, only two of the three phone numbers listed in the database belong to him. Another company secretary found that her information was used to sign up for an additional telco line.
