NTT warns its Singapore cloud was hacked and Japanese customer data compromised

Global system integrator NTT has warned of an attack on its hosting and cloud services that it feels may have seen 600 customers’ data compromised.


A Japanese-language statement that The Register has run through a pair of online translate-o-matic services says the service provider noticed a May 7th attack on Active Directory running in its Singapore operations. While the server that came under attack was quickly triaged and the service provider quickly cut off comms links, the attacker was able to gain a toehold and reach into the company’s Japanese hosting and cloud services from May 11th.


621 customers of those services were then exposed to the attack, creating “a possibility that some information was leaked due to suspicious access.”


NTT said it’s hardened up since learning of the hack, which it thinks was made possible by a migration project. It is now working with the impacted customers and will reveal as much as it can about the attack without breaching (what remains of) its customers’ confidentiality.


As with any data breach, this one is embarrassing. But as outsourcers’ whole schtick is giving clients a comfortable ride, hacks like this belie their value proposition. ®
