In recent weeks, the Russian government is believed to have initiated a handful of cyberattacks against Ukraine.

Russia annexed a portion of Ukraine in 2014.

The Russian troop buildup has prompted a flurry of diplomatic activity aimed at defusing tension.

Days later, President Joe Bidenurged Americans in Ukraine to leaverather than risk getting caught in a potential invasion.

He pointed to theNotPetyaattack, which crippled computers across Ukraine in 2017.

The malware locked up files like criminal ransomware would.

NotPetya did what it was intended to do – wreak havoc in Ukraine.

“That’s sending a signal that cyber can’t.”

Both those attacks were attributed to cybercriminals in Russia.
