INCIDENT: Taiwanese Chipmaker ADATA Attacked by Ragnar Locker Gang

The Ragnar Locker ransomware gang published download links for more than 700GB of archived data stolen from chip maker ADATA. A set of 13 archives, allegedly containing sensitive files, have been publicly available at a cloud-based storage service. A total of 1.5TB of data was compromised.

In October 2022 the Ransomhouse gang claimed to have hacked ADATA and published data on leak site. Bleepingcomputer compared the timestamps on the data shared by RansomHouse with the data leaked by Ragnar Locker in June 2021. They found that both sets of stolen data have similar timestamps, with no file being newer than May 2021. ADATA told Bleepingcomputer they were not hacked, and that this is the same data stolen by Ragnar Locker in 2021.
