Attackers claim they hacked chip maker ADATA

Threat actors claim they’ve stolen confidential data and the company’s research. Meanwhile, ADATA denies the company was breached.

Cybercriminal cartel RansomHouse added Taiwanese memory and storage chip maker ADATA to their victim list. Threat actors claim they’ve obtained 1TB of the company’s data.

While they do not specify what sort of information might have slipped from ADATA’s servers, the message on RansomHouse’s website suggests it could be related to the company’s research.

“We are sure that you are not interested in your confidential or research data to be leaked or sold to a third party,” RansomHouse’s message said.

At the time of writing this article, ADATA’s website was unresponsive and redirected users to the US version of the website. However, it’s unclear if this is related to the suspected breach.

"No new attacks"

However, ADATA claims an internal investigation showed that no data was stolen from the company.

“After a comprehensive check, our internal teams and external experts verified the information leaking in the dark web was stolen by Ragnar Locker in 2021. A new ransomware attack did not happen,” ADATA’s representative told Cybernews.

The company’s representative is referring to the breach ADATA suffered in 2021. Last June, Ragnar Locker ransomware stole 700GB of data, allegedly containing information stored on ADATA’s cloud storage.

The company’s representative explained that ADATA’s security team is confident that RansomHouse claims are false and that the gang is sharing data that was stolen from the company in last year’s attack.

“After the hit by Ragnar Locker in 2021, ADATA retained information security experts and implemented effective methods to set up a strong protection. Since then, no attack on ADATA has been successful. None of the confidential information of ADATA was leaked,” the company’s representative said.

ADATA is a Taiwan-based memory, storage, and computer case manufacturer with over 1,400 employees. The company is one of the largest DRAM manufacturers in the world.

RansomHouse is a relatively new player in the ransomware business, suspected to have emerged in December 2021. The group has victimized several organizations, including the American semiconductor company Advanced Micro Devices (AMD).
