Hey… Check this out. After income tax e-filing personal data being leaked issue, here come Telekom TM Net. Malaysia Boleh!!!
By changing number randomly at address (find out yourself), you can see others TM Net bill. Cool huh? I just discover that I am the one that pay the bill every month promptly. 
Most of them at least have 1 month bill delay payment. My God, what am I doing…? I am seeing on others bill. I cannot stop myself to look at them. Wow… Some user uses a lot of bandwidth – around 15-25GB per month. He… He… They still cannot compete with me.
Telekom, please fix this bug ASAP!!!

My god, this is serious… I knew that Malaysia’s services had defects but I would not have thought that it could go to the extent to let the privacy of their users be exposed…
That’s quite serious really!
Nice findings anyway

Privacy in Malaysia? It still need a long long time to achieve that. BTW, not all Malaysia’s services are that bad. Only a few… All Malaysian should know which one.

Issue solved. Thanks Telekom for fast response.
What a lame way of doing a web application. A simple hashing of the ID of the URL bill would’ve prevented this.
Yup… Yup… Yup… They need to come out a better software after they earn so much. Or maybe most of the money went to their own pocket?
