Cyber ​​attack on Ukrainians – attackers send letters on behalf of the tax

The Government’s Computer Emergency Response Team announced a new cyber attack on Ukraine’s critical infrastructure. Attackers speculate on the topics of fines from tax and nuclear terrorism, informs State Special Communications Service.

Thus, the distribution of letters allegedly on behalf of the State Tax Service with the subject “Notification of non-payment of tax” was revealed. The letter contains a file with the name “Imposition of Penalty Sanctions. zip” with the docx document of the same name. Opening it will eventually cause the Cobalt Strike Beacon malware to be downloaded onto the computer.

Another attack was carried out by sending a malicious document called Nuclear Terrorism A Very Real Threat.rtf. Opening this file results in the download of the CredoMap malware.

Earlier it was reported that Russia could prepare series of cyber attacks against countries that support Ukraine.

Members of the Five Eyes Intelligence Sharing Network – US, UK, Canadian, Australian and New Zealand intelligence warned of possible mass cyberattacks.
