UBS data leak: UBS reports data breach after cyber attack on provider, client data unaffected

Swiss bank UBS on Wednesday said it had suffered a data leak due to a cyber attack against one of its providers, but that no client data was affected.

Swiss newspaper Le Temps said that files containing details of tens of thousands of UBS employees had been stolen from business service company Chain IQ.

“A cyber-attack at an external supplier has led to information about UBS and several other companies being stolen. No client data has been affected,” UBS said.
