ADATA, a Taiwan-based manufacturer of memory cards and storage chips, suffers from a data leak. Over 700 gigabytes of archived data hacked by the Ragnar Locker ransomware group has been released via downloadable links.
A batch of 13 archives reportedly holding private ADATA data were made available to the public on a cloud service. The archives ranged in size from 1.1 gigabytes to 300 gigabytes.
Among the stolen files, two are extremely huge, with sizes more than 100 gigabytes. While many others that might have been downloaded quickly are 1.1 gigabytes or lower.
The ransomware operator posted download links to a new batch of ADATA business records on their leak website. It warned those who are interested that the access will not last long.
It was difficult to determine exactly what the records included because MEGA quickly took the system down.
The biggest archive, according to the cyber attacker data information, is up to 300 gigabytes. Its name offers no indication of what content it may hold. Another big archive is 117 gigabytes, with also a nondescriptive name.
Ragnar Locker hackers appear to have obtained records of ADATA on several confidential contracts, financial details, and other related documents, based on the metadata.
The ransomware incident on ADATA occurred on May 23, 2021, causing the company to shut down its servers. The company contacted the international authorities on cybersecurity to facilitate the investigation of the attack.
Ragnar Locker members said they took 1.5 terabytes of critical data and were able to do it leisurely since the company’s security was so weak. ADATA, however, chose not to pay the ransom and instead restored its systems using backups.
After the attack was discovered, the company said that it has halted the compromised systems successfully. In addition, all important steps needed to restore and improve the associated IT security systems were applied by ADATA.
The latest set of archives published by Ragnar Locker ransomware gang for ADATA is the second time. The first one was published early this month and comprises 4 small-sized zip files, with less than 250 megabytes in total. These files are still available for download.
ADATA is a provider of flash memory cards, high memory modules, gaming items, and mobile accessories. It was the world’s second-largest SSD and DRAM manufacturer in 2018.
In December 2019, Ragnar Locker ransomware was initially discovered to be used in cyberattacks targetting various potential victims.
