This was reported in the State special communications service. The Ukraine government computer emergency response team (CERT-UA) has documented the massive distribution of dangerous emails sent on behalf of the Office of the National Security and Defense Council of Ukraine.

The subject line of the emails sent out is “critical security update”. The title of the attachment also refers to a “security update”. Attached to the letter is an archive with an image of “instructions that are important to read” and an installation file. After the computer boots up and starts, the hidden remote access program is installed. This gives third parties access to computer control and data. Recently, attackers distributed emails with similar software on behalf of JSC Ukrtelecom. Probably, the purpose of the attackers is espionage.

The Office urged not to open received letters with similar attachments and not to follow the links if one is not sure of their safety.
