Hey Developers,

The Developer Relations Team is reaching out to everyone here today to provide details regarding a recent incident on the Roblox platform. Recently, we discovered a vulnerability in one of our servers. While the issue was quickly patched, there is potential that your place, could have been impacted. We’d like to reassure you that we are working to mitigate any issues caused by this situation and taking the necessary steps to prevent an incident like this from occurring in the future.

The server was vulnerable on September 7th and 8th prior to the release of the patch. The purpose of this thread is to provide you with assistance regarding how to audit your Roblox place(s) to ensure you were not affected by this vulnerability. If any unintended updates occurred during the time-frame stated previously, please make sure to follow the instructions below:

Go to your Roblox place (Configure Place option) > Check Version History for the following date: 9/7/2017 or 9/8/2017.

You can download the version history of your Roblox places by using the following link. This will help you analyze code changes by comparing the version history of any game updates before September 7th.

https://assetgame.roblox.com/asset/?id={assetId}&version={versionnumber}

Make sure to replace {assetId} and {versionnumber} with the appropriate values from your place (be sure to remove the { } characters as well). For example, to access the 2nd version of the place 1056525529:

https://assetgame.roblox.com/asset/?id=1056525529&version=2

Going to this link will download a file with a name consisting of letters and numbers (it will look something like: “22d370cde5db2d073e4444168460068a”). This file is a copy of your place. Add the .rbxl file extension (and rename the file if you like). You can then open the file with Roblox Studio and check your code.

Please make sure to audit your place(s) for any recent malicious code changes that might have occurred during the cited time-frame. If you notice any differences we highly encourage you to rollback to an earlier state of your Roblox place before the date mentioned previously. If you have any further questions or concerns please reply to this email.

Thanks,

Developer Relations Team
