The cyber-attack, which targets Microsoft Windows machines, was accompanied by ransom demands.
President Donald Trump’s homeland security advisor has revealed details of the damage caused by a cyberattack that is affecting computers worldwide.
Tom Bossert told reporters that, as of Monday morning, more than 300,000 devices in around 150 countries had been affected.
The cyber-attack, which targets Microsoft Windows machines, was accompanied by ransom demands. It is believed that a total of nearly 70,000 dollars has been paid so far around the world.
Bossert called for continuous alert. He added that the attack has hit a small number of US businesses, but so far no US federal systems have been affected.
Microsoft said on Sunday that the perpetrators used tools stolen by hackers from the National Security Agency in the United States.
Bossert did not comment directly on the remark by Microsoft. He said this was not a tool developed by the NSA but by the guilty parties, who could be criminals in foreign nation states.
