A vulnerability was found in the Electrum wallet software which potentially allows random websites to steal your wallet via JavaScript. The bug presumably also affects altcoin derivatives of Electrum such as Electron Cash. If you don't use Electrum or a derivative, then you are not affected and you can ignore this.
https://bitcointalk.org/index.php?topic=2702103.0
I actually really like the electrum wallets, they're one of the best in my opinion for bitcoin and litecoin. There is apparently an upgrade to fix the problem. We use them here locally for some auxiliary tasks. They're lightweight (don't require a lot of computing resources to use) so they're a great alternative to running a full node wallet, which uses quite a lot of hard disk space nowadays, but safer than using a web wallet (well, mostly safer, obviously there can be exceptions like this one).
I've temporarily shut down ours per the link above, and we'll upgrade tomorrow. The shutdown of these wallets doesn't affect our site in any way, we just use them for the occasional manual transaction to pay for something in crypto.
If you have a lot of money stored in wallets or even on exchanges get a crypto only PC that you keep updated, have little extra software on, and turn on rarely. It might cost a couple hundred but there’s a ton of hackers out there looking for easy money in the form of your crypto wallet.
EDIT: Trezor, Ledger, etc. are always best but for some people who keep coins on exchanges, or trade a lot it isn’t an option.

Maybe i am misunderstanding the change notes but it seems to me that that the fix that has been implemented in the newest release (v3.0.4 ~ 9 hours ago) has disabled default CORS approval which means the vulnerability could still be exploited by code running on the local computer; obviously a password protected wallet goes a long way to mitigate the chance of compromise.
While this is the case with most software i am not sure why the RPC is being enabled by default when 95% of users would have no use for it and the ones that did would be proficient enough to enable this for use.
Thanks for the heads up. Interesting to see it was first reported in Nov 2017 and not until today where a POC confirmed it as such a high risk

@steempower as I told @blocktrades too, you are very active in the steemit community, always informing people on everything, and your posts on Bitshares are really impressive. They helped me understand many more things about it!
I also wanted to stop by you and send you a big shout of appreciation for your support in one of the previous chapters of the guide. It was a huge support, and it really helped together with @blocktrades , @lukestokes , @starkerz , @cryptographic , @stephenendal , to reach many more people as expected, I have not counted again but all the first 4 chapters have reached the hands of more than 2,500+ people reach and 280+ comments and questions, and this is already amazing for me, because my aim of helping many new users, new visitors and minnows to understand as much as possible about steemit and the steem blockchain is becoming true!
Speaking about the 11 Chapter full Steemit guide, I was wondering your what do you think about it, and what feedback can you give me to improve it even more. I mentioned @blocktrades in Part 6, you can see the comment I sent to @blocktrades a few messages down here.
I will mention a lot from you in the future chapter about Steem a part of a larger ecosystem, were I speak about Bitshares!
Here is what Chapter 5 I posted today is about, and a link to it:
Chapter 5 of 11: Learning some of the many "Other ways to Earn Rewards on the Steemit Platform & Steem Blockchain" - This is part 5 of the 11 Chapters (Full Guide) to help new people make their way on Steemit

Looking forward to hear from you, in any comments section, of this or any chapter! As I told @blocktraes , your knowledge and experience together with @lukestokes @timcliff @starkerz @stephenkendal has been inspiring me to continue with the series, and even add more value and additions to it.
Regards, @gold84

Yes, from what I gathered the fix is to avoid you going to a web page that then transferred money from your electrum wallet when you unlocked it. A rogue program on your local machine can always steal money from your wallet when you unlock it. It's why I upvoted the guy who suggested you should keep a crypto computer where you don't install much software.

Just disabling RPC wouldn't really protect you from a rogue program. As soon as you unlock your wallet, a rogue program with enough privilege can send keystrokes to your wallet to do whatever it wants...

Apparently if a problem is identified it is half solved . Coin holders needs to be carefull. But i was complaining why not their is a coin personal holder which is not dedicated to any coin. Like a personal wallet can hold any cash right. Dollars, pound...... so i need a detached device which can handle any blokchain coin which is detachable like a flash disk. And when ever you want to have a transaction you will plugin and send or recive into your personal bank devise.
Daont you think we need one of those specially i make a daily exchange to ten or so coins by observing the markets so it becomes a tiresome job to open a wallet in every vender wallet.
Anyway good luck on all steemers to be profitable in cash and in the readings of blogs. Belive me i started my exchange market after reading steems. And i make a 250,000 dollars since three monthes.

Bitcoin is not anonymous, but two wallets translate addresses, making it difficult to track your payments and contacts. It is recommended that you use a new Bitcoin address on each payment request. Bitcoin does not provide information to clients on the network while the kernel is paying while receiving payments.

From Parity to Electrum, it's been tough to find a place to put your Ether that is safe from bugs, hacking, or just dumb loss.
The only lucky thing is that these wallet issues have been mostly exclusive to Ethereum and most Bitcoin services have been running strong for years.
Good news is: Steemit wallets have never given me any trouble at all, love this platform!

It is not the first time a popular cryptocurrency wallet has suffered from a bug that could potentially cost users millions of dollars. In the case of Electrum, most people use it because it is convenient and lightweight. Unlike more traditional solutions, Electrum is an SPV client, which doesn’t require a download of the full blockchain to start working. This is a blessing for people who just want a wallet capable of sending and receiving funds in a quick and secure manner. @blocktrades

¿What are electrum wallets?
Downvoting a post can decrease pending rewards and make it less visible. Common reasons:
Submit
They are "lite" wallets. For example, the electrum bitcoin wallet (located here: https://electrum.org/#home) can be used to send/receive bitcoin without requiring you to download the whole bitcoin blockchain (which is absolutely huge nowadays, so it's quite a boon). Using a lite wallet to store your bitcoin is much safer, in my opinion, than storing it on an exchange.
