“Czech Republic-based bitcoin exchange Bitcash.cz has been hacked and up to 4,000 customers’ wallets have been emptied. The company’s site is currently down, showing only a message informing of the hack, which took place on 11thNovember. The hacker is sending emails from Bitcash.cz email accounts pretending to be members of staff. The emails claim the company is having to use a US recovery company to get back the bitcoins that have been stolen. Recipients are then asked to send 2 BTC to a wallet address in order for their bitcoins to be returned. It goes without saying that this is all part of the scam and users should not send any money to the address listed.”
