Six individuals were added to the EU's sanctions list -they all have been involved in cyberattacks targeting critical infrastructure, state functions, classified information, and emergency response systems in EU member states, according to the official press release. These sanctions mark the first instance of measures against cybercriminals employing ransomware in essential services such as health and banking.

Among those sanctioned are Ruslan Peretyatko and Andrey Korinets of the 'Callisto group,' known for cyber operations against the EU and third countries through phishing campaigns aimed at stealing sensitive data in defense and external relations.

Also targeted are Oleksandr Sklianko and Mykola Chernykh of the 'Armageddon hacker group,' allegedly supported by Russia's Federal Security Service (FSB), responsible for impactful cyberattacks on EU governments and Ukraine using phishing and malware.

Additionally, Mikhail Tsarev and Maksim Galochkin, involved in deploying 'Conti' and 'Trickbot' malware under the 'Wizard Spider' group, face sanctions. These ransomware campaigns have caused significant economic damage across sectors including health and banking in the EU.

The EU's horizontal cyber sanctions regime now covers 14 individuals and four entities, involving asset freezes and travel bans, and prohibiting EU persons and entities from providing funds to those listed.

With these new measures, the EU and its member states emphasize their commitment to combating persistent malicious cyber activities. Last June, the European Council agreed that new measures were needed to strengthen its Cyber Diplomacy Toolbox.
