One issue which has been popping up lately is the "Man in the Browser" attack. Your computer is infected, and when visiting your banking account website later on, you are seeing false account information to hide unauthorized transactions. I'm sure I'm not doing this justice, so here's a recent article about the situation:http://www.bbc.co.uk/news/technology-16812064
This may be too early to report on, but after reading Seibertron's post I checked both of my credit accounts via phone application and verified all recent transactions (pending and completed). To XYL360, I tried to order from TFCC on Monday and my transaction was suspended. I was able to purchase my figures on Wednesday night once the Club successfully switched vendors. It's too early to lay blame on a TFCC purchase, but will be diligent and report back if I see any suspicious transactions beginning 1/30/12.
*sighs* Just went through this last year, possibly due to the PSN hack. Thankfully, none of the charges held and there was minimal inconvenience.
