Mexico’s monetary authority asked about a dozen banks to take emergency measures to shore up the country’s electronic payment network after a suspected cyber attack disrupted some transfers last week.
The lenders have been instructed to connect to the system via a backup method that’s seen as less vulnerable to outside intrusions, but has never before been so heavily utilized. The three banks believed to have been targeted in the attack were also ordered to hire external consultants to investigate what exactly caused the issue, according to the central bank.
