The U.S. has provided offensive cyber operations support to Ukraine amid the country's ongoing conflict with Russia, reports The Register.
Defensive and information operations were also conducted by the U.S. in Ukraine, said U.S. Cyber Command Chief and National Security Agency Director Paul Nakasone in an interview with Sky News.
"My job is to provide a series of options to the secretary of defense and the president, and so that's what I do," Nakasone noted.
Moreover, White House Press Secretary Karine Jean-Pierre noted the "above and beyond" security assistance given to Ukraine as directed by President Joe Biden.
American cybersecurity assistance to Ukraine represents a "historic" move, according to VMware Cybersecurity Strategy Head Tom Kellermann.
"The U.S. brings to bear the formidable capabilities of Cyber Command against rogue nation states. Cyberspace is a new domain for warfare," Kellermann added.
Meanwhile, Tenable CEO Amit Yoran noted that while the U.S.'s offensive cyber operations are not surprising, it was "unusual" that the operations have been publicly acknowledged.
Cybercrime operation Gold Melody, also known as UNC961 and Prophet Spider, has been discovered by SecureWorks Counter Threat Unit researchers to be an initial access broker peddling compromised network access for further attacks, according to The Hacker News.
