New submitter BitVulture writes "The hardcore Bitcoin community is abuzz with news of the closure of Inputs.io, a supposedly secure online Bitcoin wallet, after an attack resulted in the loss of 4100 Bitcoins. A PGP-signed message at the home page of the now mostly non-operational site briefly explains the situation: 'Two hacks totalling about 4100 BTC have left Inputs.io unable to pay all user balances. The attacker compromised the hosting account through compromising email accounts (some very old, and without phone numbers attached, so it was easy to reset). The attacker was able to bypass 2FA due to a flaw on the server host side.' There's no word yet whether Inputs.io will eventually resume operations or whether the security breach will force the Bitcoin bank out of business."
