I don't think you're being too paranoid, but I might not be the best one to chime in here! I had my debit card info "stolen" somehow online. I had charges on my bank statement from all kinds of websites that I knew nothing about. All together they charged my bank account almost $2000. Thankfully, my bank is investigating it and has refunded most of the money. I will never shop online again.... and I was an avid internet shopper at one time. But, that's just me. Maybe we're both being too paranoid?? I dunno. Best of luck with the Moscow, Russia charge. I hope you can get it cleared up.
