Be suspicious of email with attachments. There have been reports of emails hijacking computers and pirating your email list.This is possibly coming from Russian Hackers. Any Hacker Group in Russia is state controlled. Be careful.
Also, a good policy might be to disconnect your radio from your antennas and ground the antennas for protection against a possible EMP. I don’t want to be alarmist, but, do you feel safe with that nut job in Russia?
Thunderstorm season is coming. Also a good reason to disconnect antennas when not in use.
