The report did not say which soldiers were targeted in what Google described as “credential fishing campaigns” launched by a Russian-based group called Coldriver or Callisto. “These campaigns were sent using new Gmail accounts to accounts outside of Google, so the success rate of these campaigns is unknown,” the report said.

Russia, which is now facing heavy economic sanctions from the West following its decision to invade Ukraine on February 24, regularly denies allegations of Western cyber-attacks. In 2019, Finnish cybersecurity company F-Secure Labs described Callisto as an unidentified and advanced threat agent “interested in gathering information on foreign and security policy” in Europe. The team also targeted a NATO Center of Excellence, Google said in a report on Wednesday, without elaborating. In a statement, the center did not immediately address the Google report, but said: “We see malicious cyber activity on a daily basis.” Sign up now for FREE unlimited access to Reuters.com Register Report by James Pearson Editing by Gareth Jones Our role models: The Thomson Reuters Trust Principles.
