LocalBitcoins users took to reddit and official LocalBitcoins forums today (17th April), reporting that some bitcoin wallets managed by the company have been emptied, and that transactions have been delayed.
The Finland-based bitcoin buying and selling service has now issued an official response to these claims via its blog, stating that the problem is likely the result of a malware intrusion.

Another important thing to do is to disable JavaScript, which is susceptible to zero-day exploits. Bitcoin users with balances on hosted or "hot" wallets should always consider keeping their main cache of bitcoins in an offline or "cold" wallet.
