The Ministry of Internal Affairs on the Appeal of Roskomnadzor began checking messages about failures in the work of payment systems, the press service of the Ministry of Internal Affairs reports . Moreover, the information about this is called "knowingly false."

"Due to the advanced failure of a number of large Russian banks on the Internet, which is widespread on the Internet, a check of a number of large Russian banks, a check was started as a result of the DNS attack. The Ministry of Internal Affairs of Russia, together with Roskomnadzor, established persons involved in the distribution of knowingly false information. According to the results of the audit, a procedural decision will be made in accordance with applicable law," the report said.

In turn, the press secretary of Roskomnadzor Vadim Ampelonsky said that the failure in the work of Sberbank systems, as a result of which customers had problems with payment, transfers and removal of cash, were not associated with cyber end.

On Friday, Sberbank said that within 40 minutes, part of the bank’s customers had difficulty in conducting Internet acquiring operations, transfers and removing cash in POS-terminals and self-service devices on MasterCard and Mir cards. The reason for the problem was not specified there. It was reported that the problems of Rosbank, Vanguard and some other banks also had problems.

"The Bank of Russia is aware of an abnormal situation that occurred on the side of one of the banks. The situation continued for a short time and was promptly eliminated," the Central Bank press center said.

As TJournal wrote, the failure in the work of banks was associated with vulnerability in the system of locks of Roskomnadzor. The imperfection of the system allows the owners of blocked domains to add to the register to block the address of any sites. On Friday, authorization servers of payments were blocked in this way. In total, about 10 thousand IP addresses of various world financial organizations were on the list of blocked, of which approximately 100 technical addresses of 3D-Secure-a system used by banks to authorize Internet payments.

In early June, Russian Internet activists posted instructions into open access, which allows you to make any site inaccessible to a significant part of Russian providers.

Vulnerability leads to a site blocking from those providers who limit access to a domain name. Among the blocked domains, many are no longer used. In the instructions, it was proposed to buy free domain names from the registry and connect them with the IP addresses of those resources that need to be blocked.

The instructions that took place began to block the addresses of popular Internet services and state bodies, including Roskomnadzor itself.

To rectify the situation, Roskomnadzor compiled and sent a “white list” from more than 2000 domain masks and IP addresses of popular resources that cannot be blocked. The list includes such masks as *.yandex.ru, *.Facebook.com, *.vk.com, *.google. *, *.Twitter.com, *.youtube.com, *.instagram.com. However, this can lead to the reverse situation: any site containing a mask of this type in the address will not be possible to block the decision of the department.
