There is no bounty, RSA labs ended the $75,000 reward in 2007.

There's about 900 BTC remaining for anyone who breaks these keys:

If you break one though be careful when redeeming it, there are bots set up to pounce and steal the coins when they are transacted because the reduced entropy makes that possible. You need to submit the transaction to a mining pool that will not broadcast it until it is mined.

thats a poorly implemented reward script, if it leaves you exposed to the mining pool with this gentleman's agreement.

the script could have been designed 2 phase, so one first submits a hash of the solution & submitter address, so even if miners front-run the submitter, they just helpfully pay the transaction fee!
