Information on UBS has been stolen after cyberattack to one of its suppliers, following a Swiss newspaper report that data for more than 130,000 employees had been piracy.

“A cyberattack to an external supplier has led to the theft of information about UBS and several other companies,” the Zurich -based bank said in a statement on Wednesday. “No customer data have been affected. As soon as UBS was aware of the incident, it has taken quick and decisive measures to avoid any impact on its activities. “

Earlier, Le Temps reported that workers’ data had been published on Darknet following a ransomware attack on the Chain IQ supply provider, which was separated from UBS in 2013. According to Le Temps, a group of hacker is known to be a hacker named after the attack.

UBS did not confirm the nature of the information lost during the attack.

Increase in cyberattacks

Switzerland’s financial regulatory authority said earlier this year that reports of successful cyberspace on Swiss financial institutions increased by almost 50% in 2024 compared to the previous year and warned that the assignment of critical activities to third parties is a “key” business.

Meanwhile, the European Central Bank also warned that some banks are not doing enough to deal with cyber risks. ABN Amro NV and Banco Santander have suffered both data violations last year.

“Cyberspace not only are becoming more and more frequent, but also more and more coordinated and increasingly complex,” said Finma CEO Stefan Walter in a speech last week.

The Chain IQ confirmed on Wednesday that she and other 19 companies had been attacked, without specifying what data had been affected. The Chain IQ has undertaken the supply services from UBS in many countries a decade ago and is based in Switzerland with branches in London, New York and Singapore.

The direct telephone number of Managing Director Sergio Ermotti was also among the information leaked, Le Temps said. The data is also alleged to include workers’ addresses and details such as the floor on which they work.

The Swiss private bank Pictet was also a target, but the data leaked is limited to invoice information by some suppliers.
