The US Cybersecurity and Infrastructure Security Agency has issued an advisory urging organizations to increase cybersecurity vigilance today, the anniversary of Russia’s invasion of Ukraine, in the wake of a cyberattack against several Ukrainian government websites.
“The United States and European nations may experience disruptive and defacement attacks against websites in an attempt to sow chaos and societal discord,” the CISA advisory said.
The cyberattack in Ukraine, detected yesterday, hit the websites of a number of central and local authorities, “modifying the content of some of their webpages,” according to a statement from the State Service of Special Communication and Information Protection of Ukraine.
