Bitcoin Issues Warning Over Android Flaw
Cyber currency Bitcoin has warned that a security flaw is leaving users of its Android "wallets" vulnerable to theft.
Bitcoin Foundation said the operating system problem affected wallets where users generate the private security keys on their devices.
It said Bitcoin Wallet, blockchain.infor, BitcoinSpinner and Mycelium Wallet were some of the account types at risk.
Bitcoin said: "We recently learned that a component of Android responsible for generating secure random numbers contains critical weaknesses, that render all Android wallets generated to date vulnerable to theft.
"Because the problem lies with Android itself, this problem will affect you if you have a wallet generated by any Android app."
Software developers are working on a release which must be used to update users' apps.
The security alert came as banking regulators in the US told companies it was investigating the operating principles of Bitcoin.
Unlike traditional currencies, Bitcoin is not based in any sovereign territory.
New York's Department of Financial Services has informed more than 20 companies connected to Bitcoin that it wants information on consumer protection†and money laundering defences.
The state's officials are worried that popular virtual currencies are able to operate outside of conventional fund-transfer regulations.
