ASUS Listed by Everest Ransomware Group

If you are a customer of Asus, here’s what is being claimed, and what it would mean for you.

ASUS is a Taiwan-based multinational computer hardware and electronics company. Established in 1989, it is well-regarded for producing a wide variety of technology products such as personal computers, laptops, mobile phones, servers, Wi-Fi routers, graphics cards, and monitory. In addition, ASUS is the world's 5th largest PC vendor by unit sales. Recognized for its innovative and high-quality products, ASUS has won various international awards.
— from Everest’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.

On December 2, 2025, computer hardware giant ASUS appeared on the leak site of the Everest ransomware group. The company confirmed that internal files had been exfiltrated during a ransomware attack, though the exact number of people whose data may be exposed remains unknown.

Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

What Public Reporting Shows

Public reporting indicates that Everest posted an entry for ASUS on its dark-web leak portal. The listing states that the attackers stole internal files and are prepared to publish them if the company does not meet their demands. ASUS, the Taiwan-based maker of laptops, motherboards, routers, graphics cards and servers, has not released a detailed breach notification listing specific categories of customer or employee records. Available reporting describes the incident as a classic ransomware double-extortion case in which data is both encrypted and stolen for leverage.

December 2, 2025 marks the public disclosure date on the Everest leak site. No confirmed total of records or victim count has been published. The exposed material is described only as “internal files,” leaving open the possibility that employee records, partner contracts, customer support tickets or other personal information could be inside the archive.

Why This Matters for You and Your Family

When a company the size of ASUS suffers a breach, the ripple effects reach ordinary households. Millions of people own ASUS laptops, motherboards, routers and phones. Support tickets, warranty registrations, RMA records and customer-service chats often contain names, email addresses, phone numbers, shipping addresses and sometimes payment details. If any of that information sits in the stolen files, it can surface on criminal forums and fuel identity theft, phishing campaigns or harassment directed at you or your children.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
