An alert has gone out from IoSafe warning against a possible situation that could harm your IoSafe installations. Check to see if you have a unit that might be affected. An upgrade to their DSM software. See information below:
We would like to inform you that a ransomware called "SynoLocker" is currently affecting some ioSafe/Synology NAS users. This ransomware locks down affected servers, encrypts users’ files, and demands a fee to regain access to the encrypted files.
We have confirmed that the ransomware only affects ioSafe/Synology NAS servers running older versions of DiskStation Manager by exploiting a security vulnerability that was fixed and patched in December, 2013.
Affected users may encounter the following symptoms:
- When attempting to log in to DSM, a screen appears informing users that data has been encrypted and a fee is required to unlock data.
- Abnormally high CPU usage or a running process called “synosync” (which can be checked at Main Menu > Resource Monitor).
- DSM 4.3-3810 or earlier; DSM 4.2-3236 or earlier; DSM 4.1-2851 or earlier; DSM 4.0-2257 or earlier is installed, but the system says no updates are available at Control Panel > DSM Update.
If you have encountered the above symptoms, please shutdown the system immediately and contact our technical support here: https://myds.synology.com/support/support_form.php
If you have not encountered the above symptoms, we strongly recommend downloading and installing DSM 5.0, or any version below:
- DSM 4.3-3827 or later
- DSM 4.2-3243 or later
- DSM 4.0-2259 or later
- DSM 3.x or earlier is not affected
You can manually download the latest version from our Download Center and install it at Control Panel > DSM Update > Manual DSM Update.
