Oh, that's very unprofessional PR. But as I understand, this is only privacy issue and our coins are safe, because only bitcoin adresses, not private keys broadcasted over the network. But it must be fixed. Coinomi was my favourite wallet for Android, because they support many coins, not like Jaxx or Exodus. I hope this privacy issue will be fixed, because I don't see any good alternatives for Coinomi.

Have you found some reliable alternatives for it? Because I found Coinomi after searching a lot.
You have Exodus which support multiple coins as well but they only work in Desktop for the moment and there is Jaxx which you probably heard of before but they also faced a hack in the past (I believe private keys are stored in their servers) but they support phones so It's up to you. No they are putting the Jaxx hack out of context. It could be the person who reported it transferred his own funds to another wallet and claimed he has hacked. In fact the report was questionable because it was made right after the discovery that your Jaxx seeds could be extracted in plain text. The private keys are not stored in their servers. Please read up on it before you post. Its easy.

"This has privacy issues, meaning I can view all of your addresses and see how many coins you have, which addresses you're sending them to and which addresses you received them from.
It could also potentially open you up to a replay attack. e.g I ask you to pay me 1 BTC. I run a man in the middle attack meaning all your requests go through a computer I control before getting to Coinomi (this is possible because they aren't using SSL). I can then choose to stop the payment getting through. I say, I didn't get the payment. You can verify on the blockchain and in your client that the payment really hasn't gone through. You send it again and I receive the payment. Then at a later date I can re-send the original payment I captured which is still a valid transaction and I will receive another payment of 1BTC." Woah that just blew my mind. I had no idea man-in-the-middle attacks could even happen with bitcoin transactions! Holy crap this is like getting DDOSed right at the wrong moment to screw you over and steal your bitcoins.

i hope the dev will fix the problem so we can still using the wallet. its too bad to hear this news because i save the coins into coinomi and thank you for giving this info. i am trying to thinking to move my coins into another wallet if there is not any update from the dev. but i realize there is no guarantee for every wallet that will be 100% secure.

We put Coinomi to the test and found that connections to the back-end servers are secured with SSL.

I don't know if this is an official response, but if it is... great that you've updated to SSL. However, this has moved way beyond the SSL issue and is more about the response to the potential security issue. You probably should huddle up as a leadership team and figure out how to recover the disaster your social team created.

Ok fair enough. You should make it official so that all this questions about the vulnerability of your wallet could be address. Its been what more than 2 weeks now since the report has been reported and we haven't seen any reply from you guys. You can't just go here and post: We put Coinomi to the test and found that connections to the back-end servers are secured with SSL.
I like Coinomi. But don't let this issue ruin your reputation. At least a official statement will be enough for your users and potential users. So the feeling of doubt about your services can be cleared.

So the feeling of doubt about your services can be cleared. Agreed. Until the issue is fix and has been confirmed by other users I will still not getting you wallet. A lot has been discussed about the issue not only here but it twitter sphere and reddit. A official statement coming from you guys will qualms all fears about your wallet. And please inform as well the individual who have found the vulnerability and let him do another testing run so that there's no doubt that the issues is fix already.

As I understood right, the issue is fixed now, isn't it or should we move our coins away from old addresses?

I don't think so. Doesn't look like Coinomi thinks this is a security issue - just like what happened with Jaxx a few months ago. They even changed the title of the issue from Security Vulnerability: Coinomi transmits all data in plain text to Coinomi transmits all data in plain text. We never lied, there isn't any security implication associated with your findings. And we haven't ignored you so please stop making this personal. Unless you have something constructive to add to this, this thread will be locked. If you feel uncomfortable with the way Coinomi inquires the blockchains you may as well use a VPN service (there are several good solutions for Android) until SSL is included in a feature releases.

Oh, good that you made us aware, thanks for that. I was about to set up a wallet, but wont go this route now. Also I dont like this unprofessional behavior, they should be rather thankful to this developer because he made them aware of a security risk. I dont understand some people.

The Coinomi Phrase (the wallet private key) holds all your private keys from your used coins in the Coinomi wallet. Normally a phrase or private key is stored in the blockchain of the coin in question. Sofar i know Coinomi has not his own blockchain, so are the Coinomi phrases stored on thier server? Can anybody fill me in ![Huh](https://bitcointalk.org/Smileys/default/huh.gif)

Your private key is not stored on their server. Your private keys never leave your device actually.

No. Your private-keys are generated based on your seed - which only you have. Nothing is ever sent to a server. A deterministic wallet is a system of deriving keys from a single starting point known as a seed. The seed allows a user to easily back up and restore a wallet without needing any other information and can in some cases allow the creation of public addresses without the knowledge of the private key. More: Coinomi is a Hierarchical Deterministic (HD) wallet. What excactly does that mean?
