46elks Security Notice

From: 46elks
Date: Wed, 06 Mar 2019 16:58:56 +0100

Hello.

I am writing to inform you that yesterday at 15:46 CET one of 46elks’ physical servers was compromised by an unauthorized third party. The breach was possible due to weaknesses in the remote control system (IPMI). The server hosts virtual servers and one of those is a full node in our API cluster. This means that your data has potentially been compromised.

We have investigated this problem since 15:48 CET and have worked hard to figure out what was going on. We have no indications that any of the virtual servers or the data contained therein has been accessed or modified by this unauthorized third party.

>You are receiving this email because you have a 46elks account and, although we do not believe your personal data has been compromised, there is a possibility they might have been. We are sorry for this.
