Wow, no end to the number of these
I feel something undetected has happened to the site itself.
Apparently it's some kind of Android-based malware, so my phone was probably the culprit. What's really embarrassing is that I'm one of the "Ease of Use" panelists at the Bitcoin 2013 conference next month and I was about to sing their praises for how much easier they've made things.
It's always embarrassing to be the victim of theft I suppose, but everyone will lose some coins eventually, it's all about minimizing your losses. Thankfully I do keep the bulk of my coins in cold storage, I'd just taken a few too many coins in and hadn't sent them off to cold storage in way too long - an oversight I doubt I'll repeat after learning a $1,000 lesson.
My friend lost 7 coins a few days ago. She doesn't use android, doesn't do anything else bitcoin related, and hadn't visited the site in 6 months since she set up her wallet in October.
So how did she lose her coins? I have no idea, but something very odd is going on.
