Recently, RapidKL announced that the MRT Putrajaya line was experiencing network interference on its computer system and commuters will not be able to top up their Touch ‘n Go (TnG) credit at all MRT Putrajaya line stations for now.
But today, thanks to a question from a Twitter user, @hanapimana, we finally know what happened to the MRT line.
In a now deleted tweet, RapidKL responded by saying:
The problem with the network disruption is caused by a ransomware issue, and the relevant parties are aware of this issue. We are making efforts to ensure that the system is back up and running as soon as possible.
RapidKL still didn’t give any date as to when commuters can expect the service to be resumed to normal. For now, they advised the commuters to top up their cards at the Kajang route or other designated locations.
Meanwhile, besides the TnG transaction system, it’s not known what other data may have been encrypted behind this ransomware attack.
