Top United States counterintelligence official has advised Americans travelling to Russia for the 2018 FIFA World Cup scheduled to begin onÂ June 14Â not to take electronic devices.
The measure is called for because they are likely to be hacked by criminals or the Russian government.
In a statement to William Evanina, the officials warned World Cup travellers that even if they think they are insignificant, hackers could still target them.
Evanina is an FBI agent and the director of the U.S. National Counterintelligence and Security Center.
â€œIf youâ€™re planning on taking a mobile phone, laptop, PDA, or other electronic device with you, make no mistake; any data on those devices may be accessed by the Russian government or cyber criminals,â€ he said.
Such data especially your personally identifiable information are vulnerable.
â€œCorporate and government officials are most at risk, but donâ€™t assume youâ€™re too insignificant to be targeted,â€ Evanina added.
â€œIf you can do without the device, donâ€™t take it. If you must take one, take a different device from your usual one and remove the battery when not in use.â€
Evaninaâ€™s warning comes as U.S. intelligence, law enforcement and congressional officials are still investigating Russian hacking in the 2016 presidential election.
The probe is on whether anyone with President Donald Trumpâ€™s campaign was aware of or aided it.
Trump has repeatedly denied there was any collusion and Russia has said it did not meddle in the U.S. election.
Another U.S. official, speaking on condition of anonymity, said British security agencies have issued similar warnings to Â its public and England football team, which is competing for the World Cup.
Britainâ€™s National Cyber Security Centre (NCSC) said it was â€œproviding expert cyber security advice to the (UK) Football Association ahead of their departure to Russia for the 2018 FIFA World Cupâ€.
The NCSC, a branch of the Government Communications Headquarters (GCHQ), Britainâ€™s electronic eavesdropping agency, also issued a warning to the British public.
Private Cyber security expert Patrick Wardle said the official warnings constituted â€œreally good advice.
â€œWhen I travel to Russia, I bring â€˜burnerâ€™ devices, so if they get hacked, it doesnâ€™t really matter.â€
A burner device is typically bought for temporary use, then thrown away.
U.S. agencies have issued similar warnings before other major international sporting events, including the recent Winter Olympics in Seoul.(Reuters/NAN)
