Assistance from both inside and outside the country is being offered to Russians in fear of phone searches. Vladimir Katalov, the Moscow-based owner of phone forensics company Elcomsoft, which works with law enforcement to compile data on criminal suspects, says he doesn’t ask what nationality anyone is, but he has noted an increase in the number of people asking how to keep their data safe in an “emergency situation, whatever that is.”

His main advice, he said, is for people to not have their main device with them if they think there’s a chance it will be seized. “Get a spare phone with minimum data, probably just contacts,” he said. “Even better, get a spare SIM card, as your main one could be used to get an authentication code to log into your account.”
