Apparently hackers have exploited a vulnerability in multisig wallets and drained them.
This exploit is limited only to multisig parity wallets, so if you are not using them. You are good.
Parity has already issued a security warning here

If you are holding ether or any ether based tokens in multisig wallet, its important to immediately secure them and transfer them somewhere else
Whitehat hackers = exploited the parity vulnerability and drained wallets to secure funds [Good Guys]
The White Hat Group were made aware of a vulnerability in a specific version of a commonly used multisig contract. This vulnerability was trivial to execute, so they took the necessary action to drain every vulnerable multisig they could find as quickly as possible. Thank you to the greater Ethereum Community that helped finding these vulnerable contracts.The White Hat account currently holding the rescued funds is in

If your wallet was drained by Whitehat hackers then...
If you hold a multisig contract that was drained, please be patient. We will be creating another multisig for you that has the same settings as your old multisig but with the vulnerability removed and we will return your funds to you there. We will be using the donations sent to us from The DAO Rescue to pay for gas.Effectively we will upgrade your multisig contract for you, all you will have to do is, be patient, find your new multisig address once we have finished, and it will be like nothing happened.
Repurcussions
Ethereum and Ethereum based tokens prices may get affected by this especially if the devs have lost ethereum or the reserved tokens. But my advise would be to hold your tokens and wait for official updates from your developers. Panic selling won't bring any good since prices must have already crashed.
