Absa has laid criminal charges against the employee behind the data breach that resulted in clients' personal information being leaked to third parties.
The development came to light following an article published in the Business Insider today that reported the bank has begun contacting clients to inform them that some of their information has been compromised.
In response to e-mailed questions, the group declined to provide any information on the quantum of the leak at this stage as the investigation is ongoing. It instead stuck by its description of "a very small portion" of its customer base when referring to how many customer accounts were compromised.
Absa did confirm that some of the data unlawfully shared included sensitive information, as well as a mix of more marketing orientated data.
The types of data that was shared includes, for example, names and surnames, ID numbers, physical addresses, bank account and/or credit card numbers, mobile contact numbers and vehicle details. The data that was shared does not include passwords or PIN codes," the bank said in a statement.
Absa has enhanced the monitoring of customer accounts that have been affected to date, and are contacting customers directly," it said.
It has also enhanced the monitoring of customer accounts that have been affected to date as well as put in place additional control measures to minimise the risk of re-occurrence in future.
