The
report did not say which militaries had been targeted in what
Google described as "credential phishing campaigns" launched by
a Russian-based group called Coldriver, or Callisto.
"These campaigns were sent using newly created Gmail accounts to
non-Google accounts, so the success rate of these campaigns is
unknown," the report https://blog.google/threat-analysis-group/tracking-cyber-activity-eastern-europe
said.
Russia, which is now under heavy Western economic sanctions
following its decision to invade Ukraine on Feb. 24, regularly
denies accusations of mounting cyber attacks on Western targets.
In 2019, Finnish cybersecurity firm F-Secure Labs described
Callisto as an unidentified and advanced threat actor
"interested in intelligence gathering related to foreign and
security policy" in Europe.
The group also targeted a NATO Centre of Excellence, Wednesday's
Google report said, without elaborating.
In a statement, NATO did not directly address Google's report
but said: "We see malicious cyber activity on a daily basis."
"NATO Centres of Excellence work alongside the Alliance but they
are not part of NATO as such. We are in touch with them on this
issue," the statement said.
(This story corrects to clarify that statement was from NATO,
not a NATO Centre of Excellence)
