NTT is the large telecommunications giant of Japan. They run their network with Microsoft Active Directory. An unauthorized access was noticed and the access was not localized to one server. The active directory was partially penetrated leading to many server faults.
Before the leak was plugged, some 621 businesses were exposed.
On May 7, the system administration department detected a log of an unauthorized remote operation of the Company’s Active Directory and on the same day, the AD of the internal segment used as a stepping stone for the remote operation. The production server (server A) has been stopped urgently.
The first server the was accessed was in Singapore leading to servers in Japan which caused the detection and remediation. Evidently there was some issue with some a construction server which oversees changes to the network of managed servers. Evidently they were migrating commercial customers to a new servers when the fault were detected.
Windows Server and desktop Windows are largely the same. If a video card was supported on Windows Server I could host games and the site from the gaming desktop itself. WordPress runs on Linux which console access is easily handled with the open source Putty. Hyper-V can handle Windows, Linux and Server workloads equally well. I have to use VirtualBox to run exotic operating systems. Hercules 360 can run even zOS. The only real limitation is the price of RAM.
Games on the IBM System 360 were text based but ready the imagination was ingited. The System 360 is a 32-bit machine so it took a very long time before it reached the 4GB limits. IBM moved to 64-bit making the future for developers secure.
NTT seems to be entirely Windows Server which means they probably are using some databases. It is not hard to setup a virtual machine to allow remote access to a database. Each user has a separate account. A lot of websites use a database, catalogs, human resources and more.
When I was using Azure I was using true cloud services. The web servers can be discrete from databases. Everybody competes in the cloud. An old Lenovo laptop with 8GB of RAM can run even Exchange Server so Microsoft has resources for the self hosted small enterprise.
Given NTT mentioned how they noticed was interesting. Detecting problems fast can limit the damage done.
