Suspected members of a MageCart group that stole payment card information from customers of hundreds of hacked online stores are now in custody of the Indonesian police.

Named GetBilling by some cybersecurity researchers, the group has been operating since at least 2017 and is responsible for 1% of all MageCart incidents, at a minimum.
