Mexico acknowledges banks were hacked; losses unknown

MEXICO CITY (AP) — Mexico has established a one-day waiting period on electronic money transfers of over $2,500 in the wake of a hacking attack that may have taken as much as $20 million from several Mexican banks.

The head of the country's central bank acknowledged that a "cyberattack" was involved in shadowy transfers of between $18 million and $20 million.

The central bank issued a memo late Monday saying banks could opt to immediately pay out transfers for customers they know, but would impose a one-day wait period for others.

The head of the country's bankers' association told local media Tuesday that the hackers had apparently duplicated valid settlement payments between banks, with one copy going to the intended recipient and the other going to account set up by hackers.
