PC hardware and storage company Kingston Technology is looking into a potential data breach after hackers claimed to have stolen a trove of marketing material designed for the Asia-Pacific region.
“We are aware of claims of a security event at Kingston, and are investigating these claims,” a company spokesperson told Cyber Daily.
“Kingston continues to operate normally, without any disruption to our work or services.”
The Everest ransomware group claimed to have breached Kingston in a lengthy post on its darknet leak site on 20 August, which appears to have been generated by a chatbot given access to the stolen data.
“The Kingston data repository contains 9,438 data files with 138.49 GB of stored data,” Everest said.
“The repository is organised around regional marketing work areas, product launch folders, localisation packages, retail and e-commerce materials, channel reports, corporate communications, product imagery, layered design sources, video and compressed project packages.”
According to Everest, the data is largely marketing-related and aimed at markets in Taiwan, Japan, Korea, Thailand, Vietnam, India, Australia, New Zealand, Malaysia, and Singapore.
Material for Kingston’s HyperX gaming peripheral brands is also included in the data. The only hard evidence Everest has published, however, is a screenshot of a Windows directory that appears to include folders named after Kingston employees.
The hackers have not shared a ransom demand, but are threatening to publish within six days.
Who is Everest?
Everest is thought to be Russian-speaking and uses a variety of initial access methods, ranging from exploiting weak or stolen credentials, insider recruitment, to abusing remote access tools.
The group has been active since 2021 and has claimed 392 victims. Everest has form with targeting PC hardware manufacturers; in January, the group claimed to have stolen hundreds of gigabytes of technical data from Asrock Rack, and listed motherboard manufacturer ASUS the month before.
Everest was also responsible for a cyber attack targeting Collins Aerospace, which caused widespread disruption at airports across Europe in 2025.
