Attacks on Bitcoin

Recent attacks on Bitcoin depositorys should cause deep

It's not surprising at all that these exchanges are getting attacked/robbed blind. They are a very tempting target and they always will be. Banks were, too, until they figured out how to get physical security as right as is possible. The ones who did it badly got robbed and went out of business...the ones who did it correctly created best practices and got copied by the other banks. This will happen with bitcoin exchanges, too, assuming they survive long enough for it to shake out. And, I'd have to say that electronic security is much harder to achieve than physical security. Also, with banks, there wasn't another option to go to - - you had to keep using your cash whether you trusted the banks or not. But with bitcoin, people can just stop using it...and go back to the "old" system of cash and credit cards. So, yeah, bitcoin could get killed by this if enough people lose faith in it.

"A new Trojan has been discovered by Emsisoft, producer of PC security software. This is no garden-variety Trojan, however, it is a curious hybrid of bitcoin-mining malware and ransomware.
"Whereas most ransomware directly attacks your PC or encrypts files stored on its drives, Trojan-Ransom.Win32.Linkup blocks internet access by modifying your DNS and turns your computer into a bitcoin-mining bot at the same time

"But a separate account of the incidents by online news source The Verge paints a very different picture of the situation, suggesting that the thefts, while in some cases the fault of Coinbases users, were sizable and perhaps more frequent than has been reported.
