Indictments announced as Dutch security services said they had thwarted a cyber attack on the global chemical weapons watchdog, the OPCW involving Russian suspects and after Britain and Australia blamed the GRU for global hacking plots.
The US Justice Department on Thursday indicted seven suspected agents of Russia's GRU military intelligence agency as part of a joint crackdown with Western allies on a series of major hacking plots attributed to Moscow.
The indictments were announced as Dutch security services said they had thwarted a cyber attack on the global chemical weapons watchdog, the OPCW - expelling four Russian agents - and after Britain and Australia blamed the GRU for plots that notably targeted the US Democratic Party and global sports bodies.
John Demers, US Assistant Attorney General for National Security, said the seven agents were indicted in connection to the attack on the OPCW, on football's governing body FIFA and the US and global anti-doping agencies, and on the US nuclear energy company Westinghouse among others.
The indictments also include charges of money laundering using bitcoin, wire fraud and identify theft.
"Nations like Russia and others that engage in malicious and norm-shattering cyber and influence activities should understand the continuing and steadfast resolve of the United States and its allies to prevent, disrupt and deter such unaccountable conduct," Demers told a news conference.
"The defendants in this case should know that justice is very patient, its reach is long and its memory is even longer," he said.
The suspects, all Russian nationals and residents, were named as Alexei Sergeyevich Morenets, 41, Evgenii Mikhaylovich, 37, Yevgeny Serebryakov, 37, Ivan Yermakov, 32, Artem Malyshev, 30, and Dmitriy Badin, 27, and Oleg Sotnikov, 46, and Alexei Minin, 46.
While the latest case did not arise from US Special Counsel Robert Mueller's probe into Russian election meddling, it overlaps with it.
Yermakov, Malyshev, and Badin were among the 12 suspected GRU officers indicted in July this year by Mueller, over alleged interference in the US polls of 2016.
Demers said the operations - dating back to 2014 - "involved sophisticated, persistent and unauthorised access into the victims' computer networks for the purpose of stealing private or otherwise sensitive information."
A major part of the indictment details an alleged concerted campaign by the Russians against major international sports organisations in retaliation for the International Olympic Committee's July 2016 decision to exclude Russian atheletes from the 2016 Rio Summer Olympics due to a state-backed coverup of doping.
The hackers ultimately stole and released personal files of top world athletes including tennis players Venus and Serena Williams, US Olympic gymnast Simone Biles, and celebrated British cyclists Bradley Wiggins and Chris Froome.
Russian President Vladimir Putin has repeatedly and angrily rejected similar charges, and Russia's foreign ministry spokeswoman Maria Zakharova, reacting to the British and Australian claims, said that the allegations had been mixed together "indiscriminately."
NATO chief Jens Stoltenberg separately warned Russia to halt its "reckless" behavior.
Canada confirmed Thursday it believes itself to have been targeted by Russian cyber attacks, citing breaches at its center for ethics in sports and at the Montreal-based World Anti-Doping Agency (WADA).
"The government of Canada assesses with high confidence that the Russian military's intelligence arm, the GRU, was responsible" for these cyber attacks, the foreign ministry said in a statement.
