ok sure this is possible and is done frequently by 'good' and 'bad'

there are a few ways and one of the more popular ones are available by all

the other ways are available with the help of runners of JPJ which the road bully gangsters are surely friends of

the publicly known way is indirect and it starts with putting the car no. into the PDRM website to check saman

or JPJ site also can if there is a checking facility

from there on more info will pop up and it only takes some simple social engineering chit chat to find out
the address or current registered address of the car based on the car no plate

then info like bank HP eventually handphone number also can get

this is Malaysia - everything can do - matter of how and if you know or not only

agong paper helps too
