Possible vulnerability in the PoW core (can offer BTC)

[v.coinz]

It seems someone had found vulnerability in PoW code that cause hacker to generate PoS coins at will & amount they choose.
Is their any expert who can provide any suggestion?

This sounds like it is about an alt-coin, not bitcoin.

So one suggestion is to perhaps move it to the alt section from the bitcoin tech and dev section.

As far as other suggestions, without more detail you won't get much.

You need to post the source of your information, I think this will be issues with Altcoins with low hashing power. I doubt coins like BTC, Ethereum, Zcash, Monero, Dash etc are going to be affected

Depends what POS algo it uses and what variant, the first basis was Sunnykings design.

Here is the stuff from their forum:

POS? wtf?

Hmmmmm 

Thanks for bringing up to our attention.
Just had a quick look at the code, I don't see why it got generated.

Let me spend some time digging through this. This is a PoW Coin.

I also looked into the logs.

Block was generated by
108.61.221.227
poolsz 1

As far as I know their is no code for PoS. It's PoW coin.

If this is anyone's IP, can you please post debug log around the hash 0a5991108945d8b20def08a75e6326867f2fe7b226feb18b4974cf094fce610a

You should make a bounty with a good BTC offer in the services subforum and im sure that in no time you will have someone wanting to help you. Stuff like this is complicated and takes time to find bugs, debugging is a job so I doubt people will do it for free. So start an offer and you will get someone to fix it.

[cryptospreader_temp]

I think the bug is related to picking up wallet address while sending coins to another address. Try sending some coins to external address from your wallet without fee. And check it with block explorer. If it says POS, then the error lies there. May be a display bug. I don't think any hack, but never say.

The error must be revolving around AddToWallet() function that initiates the send function.

Where can I get the source code for the latest version?

block explorer is buggy:
