Taiwanese memory and storage chip maker ADATA suffer a massive data leak in the Ragnar Locker Ransomware attack where hackers have published download links for more than 700GB of archived data.

A set of 13 archives, allegedly containing sensitive ADATA files, have been publicly available at a cloud-based storage service, at least for some time.

The ransomware attack on ADATA happened on May 23rd, 2021, forcing them to take systems offline, the company told BleepingComputer. As the Ragnar Locker leak clearly shows, ADATA did not pay the ransom and restored the affected systems on its own.

The ransomware actor claims stealing 1.5TB of sensitive files before deploying the encryption routine, saying that they took their time in the process because of the poor network defenses.

“So then, as usual, we did offer to cooperate to fix the vulnerabilities and to restore their system and of course, avoid any publication regarding this issue, however, they didn’t value much their own private information, as well as partners/clients/employees/customers information” – Ragnar Locker

The recently leaked batch of archives is the second one that Ragnar Locker ransomware publishes for ADATA. The previous one was posted earlier this month and includes four small 7-zip archives (less than 250MB together) that can still be downloaded.
