WannaCry no more. At least for now.

WannaCry no more

I’m just going to have a short article this week, just to close off the WannaCry story and counter any of the misinformation that was spread by some supposed “experts”.

Snail mail delivers USB keys … WTF?

Bad USBs delivered by mail

I find I’m writing a second article about Evil USBs within a week. At least these ones don’t destroy your equipment, but they might infect you with nasty software that does things that you really wouldn’t want it doing. In this case, in Victoria, Australia, Evil Doers were dropping USB drives into people’s mailboxes. The…
