Nexperia, a leading semiconductor manufacturer based in Nijmegen, Netherlands, has fallen victim to a significant cyberattack. The Dark Angels (Dunghill) ransomware group announced its responsibility for infiltrating the company’s servers and exfiltrating a staggering 1 terabyte of confidential data.

Owned by Wingtech Technology, a partially state-run Chinese entity, Nexperia employs around 14,000 individuals globally and operates key manufacturing sites in Hamburg, Germany, and Greater Manchester, England. The company is renowned for its extensive array of products, including transistors, diodes, and logic devices.

The breach was first acknowledged by Nexperia in March 2024 after discovering unauthorized access to their IT systems. In response, the company quickly isolated the compromised servers from the internet and initiated a thorough investigation with the aid of FoxIT, a third-party cybersecurity firm.
