Indonesian hackers going with the group handle of Gantengers Crew hacked and defaced the Online Resources domain of US based Financial Services Company MasterCard.
Hackers left a deface page along with a note on the website, but the reason for targeting MasterCard website wasn’t mentioned anywhere.
It’s not clear if the hackers had access to user’ credit or debit card data or not. However, considering the groups previous hacks, it can be assume that it was just another random hack on a high-profile co-operate website.
