RansomEXX ransomware attacked Gigabyte

RansomEXX ransomware operators attacked a large Taiwanese computer hardware manufacturer Gigabyte. The hackers are currently threatening to release more than 112GB of data stolen from the company if it does not pay the ransom.

Gigabyte officials have already confirmed to the media that the company was affected by the cyberattack, but stressed that the incident affected only a small number of servers. Having discovered anomalous activity, Gigabyte specialists promptly took the remaining IT systems offline and notified law enforcement agencies about the incident.

Bleeping Computer reports that the ransomware group RansomEXX is behind this attack. The fact is that its own source provided the publication with a link to a closed hacker page, created specifically for Gigabyte, where hackers claim that they stole 112 GB of data during the attack.

The ransomware RansomEXX started its activity under the name Defray in 2018, but in June 2020 it was renamed RansomEXX and became more active. Like other ransomware, RansomEXX can hack into the network using Remote Desktop Protocol, exploits, or stolen credentials.

RansomEXX not only targets Windows devices, but can also encrypt data on Linux virtual machines running VMware ESXi servers.

Other high-profile attacks by the ransomware gang include attacks on Brazilian government networks, the aircraft manufacturer Embraer, the Texas Department of Transportation (TxDOT), Konica Minolta, IPG Photonics and Tyler Technologies.
