Microsoft specialists reported that Ukrainian computer networks were attacked by a new malware called FoxBlade a few hours before Russia invaded Ukraine.
“A few hours before the start of the conflict on February 24, we recorded a number of offensive and destructive cyberattacks directed against the digital infrastructure of Ukraine,” said Microsoft President and Vice Chairman Brad Smith.
The experts immediately informed the Ukrainian government about the situation, notified about the discovery of a new FoxBlade malware and provided technical recommendations on how to counteract the attackers.
In addition, the company has updated its Windows Defender security platform with new signatures to block the FoxBlade malware within three hours after the malicious tool was detected. FoxBlade is a Trojan that can use computers to carry out distributed denial of service (DDoS) attacks”without the knowledge of the owners.
