The Dark Angels (Dunghill) ransomware group claims responsibility for hacking chipmaker Nexperia and stealing 1 TB of the company’s data.

Nexperia is a semiconductor manufacturer headquartered in Nijmegen, the Netherlands. It is a subsidiary of the partially state-owned Chinese company Wingtech Technology. It has front-end factories in Hamburg, Germany, and Greater Manchester, England. The company’s product range includes bipolar transistors, diodes, ESD protection, TVS diodes, MOSFETs, and logic devices.

The chipmaker has 14,000 employees as of 2024.

The Dark Angels ransomware group added Nexperia to the list of victims on its Tor leak site. According to the announcement, the stolen data includes:

- 285 Gb of quality control data

The group published a set of files as proof of the security breach and threatens leak all the stolen data if the victim will not pay the ransom. 

The chipmaker confirmed it became aware of the unauthorized access to certain Nexperia IT servers in March 2024.

In response to the incident, the company disconnected the affected systems from the internet to prevent the threat from spreading. The Nexperia launched an investigation into the security breach with the help of third-party cybersecurity experts.

“we have reported the incident to the competent Authorities, including the ‘Autoriteit Persoonsgegevens’ and the police, and are keeping them informed of the progress of our investigation.” reads the press statement published by the company. “Together with our external cybersecurity expert FoxIT, Nexperia continues to investigate the full extent and impact of the matter and we are closely monitoring the developments. In the interest of the ongoing investigation, we cannot disclose further details at this point.”

In September 2023, the Dark Angels ransomware group hacked Johnson Controls and demanded a $51 million ransom.
