Code Spaces e os riscos da cloud

O serviço Code Spaces foi liquidado por um atacante que obteve controle da consola de gestão da AWS:

On Tuesday the 17th of June 2014 we received a well orchestrated DDOS against our servers, this happens quite often and we normally overcome them in a way that is transparent to the Code Spaces community. On this occasion however the DDOS was just the start.

An unauthorised person who at this point who is still unknown (All we can say is that we have no reason to think its anyone who is or was employed with Code Spaces) had gained access to our Amazon EC2 control panel and had left a number of messages for us to contact them using a hotmail address

Reaching out to the address started a chain of events that revolved arount the person trying to extort a large fee in order to resolve the DDOS.

Upon realisation that somebody had access to our control panel we started to investigate how access had been gained and what access that person had to the data in our systems, it became clear that so far no machine access had been achieved due to the intruder not having our Private Keys.

At this point we took action to take control back of our panel by changing passwords, however the intruder had prepared for this and had already created a number of backup logins to the panel and upon seeing us make the attempted recovery of the account he proceeded to randomly delete artifacts from the panel. We finally managed to get our panel access back but not before he had removed all EBS snapshots, S3 buckets, all AMI's, some EBS instances and several machine instances.

In summary, most of our data, backups, machine configurations and offsite backups were either partially or completely deleted.
