It's unclear why a hacker would add a passphrase to someone else's wallet, when it would be more effective to just copy the private keys and transfer the coins to their own address.  Unless they did it by mistake.

@NateEldredge not entirely true. I had a test system for malware for Windows wallets and EXEcoin had malware which encrypted the dat file and tried to send it via ftp. It's plausible malware malcontents would wait if the wallet showed significant activity ie to wait for more BTC from those keys. But it's much more likely OP forgot the password

@NateEldredge It would be marginally less suspicious to encrypt the wallet than delete it or steal them outright. Encrypting it is something you might do and forget about.

unfortunately there is no easy way to recover the password, you can try bruteforce but you will need a lot of computing power

Do you recall **any** possibilities?

What do you mean, you don't remember setting up a passphrase?
Either you did do it yourself, or someone else had access to your computer and set a passphrase, effectively disabling your money.

### Answer by username_4 on 2014-08-31. Score: 1

Did you:

1. Change your client software?
2. Change your operating system?
3. Install Updates eg. Java/Qt/...?
4. Swap ISP?
5. Checked blockchain.info (for transactions on your wallet?)

My first assumption would be that you got hacked (if your wallet.dat was in it's predefined environment) and that the one controlling has added as password *or* you have encountered a bug somewhere which has not been reported and fixed.

If you could add your litcoin address(es) I can do some investigation.

Thank you.

Best regards,
