Synology sent a note today saying that they have more information on the SynoLocker vulnerability we reported on earlier. The bottom line seems to be that one should move to newer versions of Synology DSM. It also appears as though DSM 5.0 is not impacted by the SynoLocker ransomware. For users that need validated versions of DSM for their environments, Synology has updated versions which do not have the vulnerability. Certainly something every Synology user should look at.

Synology® Continues to Encourage Users to Update
Washington, Bellevue—August 5th, 2014 —We’d like to provide a brief update regarding the recent ransomware called “SynoLocker,” which is currently affecting certain Synology NAS servers.
We are fully dedicated to investigating this issue and possible solutions. Based on our current observations, this issue only affects Synology NAS servers running some older versions of DSM (DSM 4.3-3810 or earlier), by exploiting a security vulnerability that was fixed and patched in December, 2013. Furthermore, to prevent spread of the issue we have only enabled QuickConnect to secure versions of DSM. At present, we have not observed this vulnerability in DSM 5.0.
For Synology NAS servers running DSM 4.3-3810 or earlier, and if users encounter any of the below symptoms, we recommend they shutdown their system and contact our technical support team here: https://myds.synology.
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.
- A process called “synosync” is running in Resource Monitor.
- DSM 4.3-3810 or earlier is installed, but the system says the latest version is installed at Control Panel > DSM Update.
For users who have not encountered any of the symptoms stated above, we highly recommend downloading and installing DSM 5.0, or any version below:
- For DSM 4.3, please install DSM 4.3-3827 or later
- For DSM 4.1 or DSM 4.2, please install DSM 4.2-3243 or later
- For DSM 4.0, please install DSM 4.0-2259 or later
DSM can be updated by going to Control Panel > DSM Update. Users can also manually download and install the latest version from our Download Center here: http://www.synology.com/
If users notice any strange behavior or suspect their Synology NAS server has been affected by the above issue, we encourage them to contact us at security@synology.com.
We sincerely apologize for any problems or inconvenience this issue has caused our users. We will keep you updated with the latest information as we address this issue.
