Russian web hosting provider ESTT said a cyberattack that used file-encrypting malware disrupted services across its cloud infrastructure on Sunday.
The company said it had restored 90% of its customers’ virtual servers by Monday, though 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.
ESTT, whose customers include major businesses, was hit by a large-scale distributed denial-of-service (DDoS) attack in July 2025.
That attack disrupted services at restaurant chains Vkusno i Tochka, Mnogo Lososya, Cofix and Sushi Master, as well as restaurant management software provider iiko, the Vedomosti business daily reported.
The latest attack came less than a week after hackers destroyed the cloud infrastructure of Beget, another Russian hosting provider.
The Nov. 2 outage affected around 500,000 online resources, including government service websites, news outlets and online stores, according to the RBC business news outlet.
The car-sharing service BelkaCar switched providers after its app was disrupted.
The attack also temporarily prevented Beget from registering new Russian domain names.
As of early November, it was Russia’s third-largest registrar by number of domains registered under .ru and .рф, RBC reported.

A Message from The Moscow Times:
Dear readers,
We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."
These actions are direct attempts to silence independent journalism in Russia. The authorities claim our work "discredits the decisions of the Russian leadership." We see things differently: we strive to provide accurate, unbiased reporting on Russia.
We, the journalists of The Moscow Times, refuse to be silenced. But to continue our work, we need your help.
Your support, no matter how small, makes a world of difference. If you can, please support us monthly starting from just $2. It's quick to set up, and every contribution makes a significant impact.
By supporting The Moscow Times, you're defending open, independent journalism in the face of repression. Thank you for standing with us.
