On February 25, 2022, two days after Russia began its military invasion of Ukraine, the U.S. Cybersecurity & Infrastructure Security Agency (CISA) issued a rare ‘Shields Up’ warning for U.S.-based organizations, stating: “Every organization—large and small—must be prepared to respond to disruptive cyber activity.”
The Shields Up warning is in direct response to increased Russian cyber aggression against Ukrainian and other targets in the region, including recent distributed denial-of-service (DDoS) and malware attacks. In addition to the possibility of disruptive nation-state activities affecting U.S. targets, CISA also warned of an increase in cyber attack activity against U.S. organizations from Russia or hackers acting on Russia’s behalf.
