According to reports, the European Parliament website was the target of a cyber attack on Tuesday by a group of pro-Kremlin hackers. The hackers infiltrated the site and posted a message on the homepage that was highly critical of European Union (EU) leaders.

The "sophisticated" cyberattack on the EU Parliament website was launched after the Parliament declared Russia a state sponsor of terrorism.

According to a Telegram post, KILLNET claimed responsibility for numerous politically-motivated DDoS attacks, including those targeting US government websites.

That same day Russia invaded Ukraine, and pro-Russian hackers unleashed a cyberattack on a satellite operator, disrupting Ukrainian communication. However, the scope was such that this attack spread to wind turbines in Germany.

According to a joint cybersecurity advisory released in April, Russia has increased attacks on critical infrastructure from members of the Five Eyes intelligence alliance. The attacks could target countries that have supported Ukraine, especially those who provided conventional weapons to help the country defend itself.

Despite Russia's invasion of Ukraine, Finland and Sweden have joined NATO. The alliance's Cooperative Cyber Defence Centre of Excellence (CCDCOE), which includes countries not part of the larger military alliance, has also expanded.

Earlier this month, Japan became the latest addition to the CCDCOE. Earlier this year, South Korea, Luxembourg, and Canada joined the center. Following a unanimous vote of approval, Ukraine became an involved participant in March.

Despite the relatively small impact of the cyberattack on the EU Parliament's website, partnerships like the CCDCOE are essential to understanding and staying ahead of cyber threats as they emerge.
