Ransomware attack disrupts cloud services at Russian hosting provider ESTT

Russian web hosting provider ESTT said a cyberattack using file-encrypting malware disrupted services across its entire cloud infrastructure on Sunday, according to The Moscow Times.

According to the same outlet, the company said that by Monday it had restored 90 % of its customers' virtual servers, although customers still could not access their account dashboards. ESTT said it had found no evidence of a customer data leak and gave no timeline for fully restoring services.

The Moscow Times notes that the attack came less than a week after attackers destroyed the cloud infrastructure of Beget, another Russian hosting provider; that outage on November 2 affected around 500,000 online resources, including public service websites, news outlets and online stores, according to the business daily RBC cited by The Moscow Times. There is no information linking the two attacks.

It is not known who is behind the attack on ESTT or how many customers have been affected.

Developing story: so far we have only been able to read The Moscow Times report; ESTT's own statement or a second independent source confirming the scope and degree of recovery is still needed.
