I had account to exchange that is using cloudbleed Smiley very good for me i am around this forum all day long and had information from here 1st...

After 1-2 days email arrived from exchange to change password and OTP also Smiley

I really can't believe that up to now... some years before the OTP was announced to be something like unbreakable and here we are Smiley

Over the past 5 years from the experience we have in every day using computers ( no matter the level) i understood one thing...the only unbreakable is the BTCitcoin Smiley

But anyway, in the community we not hear anything bad from this bug to any exchange happening etc... so all is good !

Nice thread, I was looking for a list of all the sites that might be affected and I didn't see one until just now.  It's always a good idea to have 2FA enabled on all accounts.

Money often costs too much.
I wonder when bitcointalk would use 2fa. It would be great if they decide to implement it soon..

Nope. There allready is something far superior active. You can add a BTC address onto your profile (or post it somewhere (there's a thread for that where people quote those postings for tamper proofness)) and if THAT breaks, the whole Saga is over anyways.

2FA usually just adds an Android cellphone and everybody of us knows those aren't adding to your security but substracting from it.

I have to start using a password manager to deal everything now which i have been avoiding all this while.
Yeah well, I've tried using one before but decided against continuing its use after some time. It's just an additional worry.
Frankly, couldn't stop worrying that the password manager I use would be the weak point, and then ALL of my accounts woulda been compromised.
Decided to go old school instead and keep a hard copy.  Grin Nothing better than pen and paper.  Grin

Almost every site uses CloudFlare nowadays. AND that bug has been there for months.  Roll Eyes

Open source password managers are not so bad, you know you are the only one holding your passwords, the file where the passwords are contained is encrypted and you need a master password, if you like better to have a hard copy there is not a problem but password manager can save lots of time.

Shit, gonna have to go and change my blockchain API.

I'm glad this was caught relatively sooner rather than later, but it's a shame there is another issue of this kind.

Luckily I don't have anything of considerable value stored on anything there, maybe $10 across all the affected sites you mentioned. Either way, better to be safe rather than sorry.

Holy Shit, a lot of big sites has been affected : 4,287,625 possibly affected domains. Some of these like Fiverr and Uber  are also on the list.

Damn, this is a major oversight on their side, and I think a bunch of these sites are going to cancel their membership after this. You think you are

relatively safe, and then something like this happens.  Roll Eyes

Sound advice. It's worth adding that if you previously set up shared secret 2FA between 2016-09-22 and 2017-02-18 on one of the affected sites you should get a new secret in addition to changing your password. Usually disabling and reenabling 2FA is the way to do that.

Good idea, added "Change 2FA" and "API keys" to the subject and in the TL;DR with red font.

1.How does that contribute to any discussions here ? Off-Topic Much ?
2.We're suppose to be talking about services using Cloudflare and not password managers..
3.Not every site.The sites which are prone to DDos do.Finally people can stop using that crap.
4.Not anytime soon.Neither is a feature request on the new forum.
1.What, I can't comment on a point in his post I find interesting? As for topic, SEE the hr line?
2. Nitpick-much? Should I rearrange my post and place the middle part on top to stop your fussing?
3.Hence the word 'Almost'. And finally, the only part of your post that's got anything to do with the 'topic'.
4.Ahuh. Whatever you say.

As for topic ( Grin in case there's another fuss),
the bug's been there for months(September last year), Cloudflare was clueless, and for the bug to be found and reported by someone from Google?  Roll Eyes

Anyway, for anyone who hasn't done so yet, make sure to change your account's password and activate 2fa if possible.

Remember to make your passwords strong and never reuse on multiple sites.
(You could use password managers or make hard copies to keep track of your account details.  Tongue Tongue Grin Grin Grin)

give me your cryptos
Anyone knows what kind of vulnerability the Cloudflare exploit has? May I know why do we need to change our passwords?

It's obvious that they won't give you the exact details and nature of the bug no system is perfect, so there's bound to be more.

From the email that Kraken and poloniex sent me, the nature of the bug seems to be something to do with CloudFlare's reverse proxy system stuffing up. In very rare cases, secure HTTPS requests were able to be read, meaning things like passwords and 2fa keys could have been skimmed.

Thanks for this warning. Many people using this sites  that affected in cloudbleed bug will be aware now. I will change my password too, but Is this safe already if I change my password? Or I need to activate my 2FA security so that my account will be surely safe now? Or I need to do something ?

really thank you for the warning on. I will change all your account information, and then set the security code 2FA. but I want to know why they are using CloudFlare, this is quite dangerous. what will happen if their users lose money, they are responsible or not ?

I don't see anyone talking about this here so I'll start it here because of its importance and move it to services discussion later.


TL;DR: Bitcointalk is not affected, there is a small chance exchanges and web wallets are affected. To be safe change your password and enable 2 Factor Authentication.



You may have heard about the Cloudflare bug that leaked lots of sensitive information if not read more about the details here:
https://blog.cloudflare.com/incident-report-on-memory-leak-caused-by-cloudflare-parser-bug/

In any case you should change all your passwords on services that were using Cloudflare and are affected by this bug in order to be safe. You can see more information and the list of affected services here:
https://github.com/pirate/sites-using-cloudflare/blob/master/README.md

Also there is a website to check if a website was using Cloudflare (not sure how reliable it is):
http://www.doesitusecloudflare.com/

Name|Uses cloudflare (May Be Affected)
Bitcointalk|No (does not use Cloudflare)
Bitstamp|No (does not use Cloudflare)
Blockchain.info|YES
Bitfinex|YES
Coinbase|YES
Localbitcoins|YES
Poloniex|YES
Bittrex|YES
Kraken|YES
Bitpay|YES
Btc-e|YES
Cex.io|YES
C-cex|YES
Yobit|YES
* These sites may or may not be affected by the bug, but it is safer if you change your password immediately and enable 2FA. Better safe than sorry
** Just checked a couple of gambling sites, and they all use Cloudflare. Not going to list them here since they are of less importance but you have been warned.

Help me complete the table.
Thanks for this update. This helps a lot of users from different site to be alert for this cloud bleed bug which can cause for leaking sensitive personal informations. This is a big deal issue and we all need to pay attention for this kind of issue to avoid getting hacked. As of now, I don't receive any emails notifications from my account but i will change password as soon as possible, thanks again OP for alerting us.

i've got the email from poloniex and bittrex too and its said that i should change my password and my 2FA because of security reason and i read the news about cloudflare that have a bug and the site that using cloudflare is potential for the attack. i already asked with poloniex and they request for their member to change their password and 2FA, just to make sure that their member is safe from the attacker. it is good that we know about this news so we can secure our account from the ataccker and we need to activate 2FA for our account.
