According to https://bitcointalk.org/index.php?topic=271831.0 there’s a massive flaw in random number generation on Android devices, which means moving coins out of any address that’s been generated or spent via an Android device.

No idea on details yet. I’m updating my blockchain.info client now though.

(Add: Always remember to take backups up new addresses)

Bitcoin – still not quite ready for mainstream use 😉

(ETA: Link to official bitcoin.org announcement. Also looks like blockchain.info’s wallet is down, making it difficult for anyone looking to move coins around quickly.)

(Also, here’s the paper with technical details of the underlying RNG problem if you’re interested.)
