One year after Russia’s invasion of Ukraine, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) warns organizations to increase vigilance.

Exactly one year, Russia invaded Ukraine, and now one year later the U.S. Cybersecurity and Infrastructure Security Agency (CISA) is urging organizations and individuals to increase vigilance.

The US agency warns that the United States and European nations may be targeted with disruptive attacks and defacement attacks against websites. The attacks aim at attempting to sow chaos and societal discord on February 24, 2023, the anniversary of Russia’s 2022 invasion of Ukraine.

“CISA urges organizations and individuals to increase their cyber vigilance in response to this potential threat.” reads the alert. “In response to the heightened geopolitical tensions resulting from Russia’s full-scale invasion of Ukraine, CISA maintains public cybersecurity resources, including Shields Up—a one-stop webpage that provides resources to increase organizational vigilance and keep the public informed about current cybersecurity threats.”

• review the Shields Up webpage, which includes guidance on:
  • Increasing organizational vigilance
  • Implementing cybersecurity best practices

The current situation could impact organizations in Ukraine and abroad, they can be targeted with malicious cyber activities such as cyber espionage, sabotage and misinformation campaigns. The US government warns that organizations of every size must be prepared to respond to disruptive cyber incidents.
