The 114.79.13.0/24 subnet belongs to the fastest and cheapest prepaid wireless provider in Indonesia, and yes there are many hackers club in Indonesia which makes other legit users have to swallow the bitter pill.
One of the problem in Indonesia, many people here are still unaware about the identity theft.
Due to the very tough competition many financial institution uses third party marketers to sell credit cards in malls and public areas. Most of these marketers are paid with a minimum transport and meal and $5 - $10 for every approved credit cards.
If we are interested to have a new credit card and we already have one from other bank, usually the marketer help us to fill in the form, ask us a photocopy of front end and back end of our existing credit card and ID Card (they even "help" us to copy our cards to a nearby photocopy shop).
By providing a copy of our existing credit card, there will be no on-site verification to our address, therefore many people tend to choose this method.
Now imagine. They have all our personal data in the form along with a copy of our existing credit card and ID card. Another scary scenario, the possibility if they copy our credit card using a skimmer when they "help" us to make a photocopy of our cards.
There are many more, but I think the brief explanation might give a picture of why Indonesia is known as one of the most high risk country in on-line transactions.
