More than a dozen Pakistani banks have suffered a "hack" that has led to the theft of data from thousands of debit and credit cards in the last two months, an official source told Efe on Monday.
"More than ten Pakistani banks have suffered the theft of data from debit and credit accounts recently," said the director of the Cybercrime Department of the Federal Investigation Agency (FIA), Mohamed Shoaib.
The source indicated that "thousands" of accounts have been affected and that more than one hundred customers have reported that payments were made with their cards that they had not made.
The attacks began around two months ago, but in the last two weeks they have increased in intensity.
BankIslami reported on October 27 that 2.6 million rupees (about 17,000 euros) had been stolen from several of its clients' accounts through international card payments.
The agent said his unit is getting in touch with representatives of the banks to discuss the "sensitive" situation.
Several people have been arrested in the investigations, which follow their course.
In addition, several banks have sent text messages to their customers informing them that they have "blocked" the use of credit cards in online purchases and their international use "as a security measure".
Last week a group of "hackers" was arrested when they posed as military officers and took money from banks using the stolen data.
