Hosting firm says it lost all customer data after ransomware attack

Danish hosting firms CloudNordic and AzeroCloud have suffered ransomware attacks, causing the loss of the majority of customer data and forcing the hosting providers to shut down all systems, including websites, email, and customer sites.

Hi all,

As self-hosting is not just “home-hosting” I guess this post should also be on-topic here.

Beginning of the year, bleeping-computers published an interesting post on the biggest cybersecurity stories of 2023.

Item 13 is an interesing one. (see URL of this post). Summary in short A Danish cloud-provider gets hit by a ransomware attack, encrypting not only the clients data, but also the backups.

For a user, this means that a senario where, not only your VM becomes unusable (virtual disk-storage is encrypted), but also the daily backups you made to the cloud-provider S3-storage is useless, might be not as far-fetches then what your think.

So … conclussion ??? If you have VMs at a cloud-provider and do daily backups, it might be usefull to actually get your storage for these backups from a different provider then the one where your house your VMs.

Anybody any ideas or remarks on this?

    I have been thinking the same thing.

    I have been looking into a way to copy files from our servers to our S3 backup-storage, without having the access-keys stored on the server. (as I think we can assume that will be one of the first thing the ransomware toolkits will be looking for).

    Perhaps a script on a remote machine that initiate a ssh to the server and does a “s3cmd cp” with the keys entered from stdin ? Sofar, I have not found how to do this.

    Does anybody know if this is possible?
