How to protect your TNAS from Deadbolt ransomware?
We've been receiving reports recently that some users' TNAS devices are being attacked by the Deadbolt ransomware. According to our study of these cases, once the device is attacked, the user's data will be encrypted. The Deadbolt ransomware will mutate and launch attacks according to different NAS devices. Thousands of NAS devices of other brands have been attacked by the Deadbolt ransomware over the past month. Unfortunately, TNAS has also become the target of this attack.
After studying this ransomware, we have fixed the vulnerabilities in the TOS system that may be exploited by the ransomware. We will continue to work hard to improve the security of the TOS system and release updates in time.
What should I need to do now?
1. Immediately check whether your TNAS device is under attack;
2. If your device has not been attacked, please refer to the guidelines to improve your TNAS security;
3. If your device has been attacked, please refer to the following countermeasures.
What should I do if my TNAS has been attacked by Deadbolt ransomware?
1. Shut down the TNAS device; x.86 models: short press the power button; ARM models: long-press the power button for 3 seconds;
2. It is recommended that you re-install the latest version of the TOS system (4.2.30 or later) to prevent unencrypted files from continuing to be encrypted.
3. If your files have been encrypted, reinstalling the TOS system can not help you deal with the encrypted files, but will allow you to continue to use the device more safely;
4. If you want to perform other decryption operations, you may not be able to enter the Deadbolt key to decrypt after reinstalling the TOS system, please operate with needed.
