One of my servers was actually shut down for doing penetration tests on getting the ip.
So everybody should think about if even this is possible to try or allowed.

In light of the above happening, I would be releasing the IP tomorrow so that you dont have to go and search for the IP and maybe attack other servers. Will be releasing the IP tomorrow around the same time and would consider that everyone is informed by then.

I would also like to modify the challenge a little bit to prevent this from happening again.

1. Please submit your IP to become a part of the next phase. You will only perform the test from that IP and now the hack will be closed event. The IP will only be released to the group of people who submit their IP addresses.
2. Maximum number of threads/connections to the server should be 1 per IP.

If someone can come up with other rules, please advice me and I will add.

Sorry to Gitju for the trouble.

Thanks.

I posted it on AnonOps irc #hacker.
The more work on it the better.
I got an idea on how to get the ip and will try it.
Then this competition will end for me as the second part can't be done in my country without a written legitimacy.

Dont worry. Will tell you exactly how to configure the server locally and test it. This way you can try, and let us know the steps and we will perform it.

Bitcoin connects to TOR on ip 9050. TOR connects 9050 to its network using higher ports. see:-

tcp 0 0 localhost:9050 localhost:47342 ESTABLISHED
tcp 0 0 localhost:46330 localhost:9050 ESTABLISHED
tcp 0 0 localhost:47342 localhost:9050 ESTABLISHED
tcp 0 0 localhost:9050 localhost:46330 ESTABLISHED
tcp 0 0 localhost:9050 localhost:38319 ESTABLISHED
tcp 0 0 localhost:38319 localhost:9050 ESTABLISHED

9050 - 47342 ; 47342 - 9050

Thus its not the 9050 that you should be looking for, it should be higher ports. Firewall will block 9050 but not the higher port.

Current netstat (This is ofcourse not the complete list). I really dont know if these ports can be scanned.

Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 localhost:49210 localhost:9050 ESTABLISHED
tcp 0 0 localhost:9050 localhost:49210 ESTABLISHED
tcp 0 0 localhost:50715 localhost:9050 ESTABLISHED
tcp 0 0 localhost:9050 localhost:50715 ESTABLISHED
tcp 0 0 localhost:9050 localhost:38319 ESTABLISHED
tcp 0 0 localhost:38319 localhost:9050 ESTABLISHED

There could furthermore be other special actions be taken like the application server is behind a firewall and directly connected with one special tor entry node that was extra setup for this purpose and their application server just communicates with this one special tor entry node and their firewall blocks all other external accesses that do not come from their tor entry node.

This would work for us but we intend to get a new IP every so many hours/days. If there was one partcular TOR node that we connect to, it would become little easier to trace. Regarding the java app, it doesnt use TOR as the bandwidth requirement is huge. Consider checking email and replying in less than a second forever. It wont be beneficial to burden the TOR network with useless bandwidth when only google will be able to see the IP.

Then i use this code to make the a big ip data base by range:

Code:

#!/bin/bash
for a in $(seq 79 79)
do
for b in $(seq 125 125)
do
for c in $(seq 0 127)
do
echo $a.$b.$c.13
echo $a.$b.$c.113
echo $a.$b.$c.213
echo $a.$b.$c.13 >> list1.txt
echo $a.$b.$c.113 >> list1.txt
echo $a.$b.$c.213 >> list1.txt
done
done
done

Whit that i got 90,000 ip's... *.*.*.13, *.*.*.113, *.*.*.213

For find up/down servers i use "Angry IP Scanner"...

And i found 13,500 up servers ip's...

If i discard the *.compute.amazonaws.com ips, i got 1,519 ip's

The problem its if i make a scan for that 1,519 ip's searching for port 9050, i dont found any ip with that port open.

I make a scan for the 13,500 ips, and they dont have TOR service with that 9050 port open.

I realy enjoy this chalenge, but the info you give us are incorrect, i got all the Amazon ips ending with 13, 113, 213. and it doen't use TOR. Maybe my Angry IP Scanner fail with that port. But i can publish that ip list and if your server have an amazon ip, it must be on the list.

This is how to find the ip.

I assume in theory there are currently 3 ways to find the IP:

1. Through the e-mails, but obviously we "cannot".
2. Connect to as many bitcoin (testnet) nodes as possible and see who relays the transaction as first. But I guess this is not possible because you guys use bitcoin through TOR.
3. Guess which server

Considering you know: 1) it's from Amazon 2) we know exactly which ports are open 3) we know the (test) IP ends with .13 - we have some parameters to search on, but still it will be a long lucky search, I guess Tongue

And the production application server would be basically 256 times more difficult.

To be honest I was more interested in that mobile phone app.. I assume that also has to communicate to the application server (through that Java app I guess)? Or we will just get more info about that in "the second part"?

That aspect of testing will be in the next bounty. Nothing goes inside the app server without an email or without the server itself going and fetching data. After this challenge is over, we will go for the bug finding challenge but the bounties will be less as it will be only for bugs and then maybe another challenge to hack the webserver.

U are telling the hacker what route he'll take to hack u ? Your request is not to hack the web server, but the app server and that is also by finding IP ? Cheesy

Your whois details are not yet protected Tongue

Let us know once u gather some money from your customer. U'll see the real hunters then. Good Luck Wink

Comment from my partner :

"The whois details are designed to be displayed but the domain transfer is locked and the DNS is maintained by cloudflare. Nothing can be done on that aspect. The idea to leave it open was that we will adding further business information instead of making it private.

Further, this whole hacking challenge has been designed around an assumption that some senior level staff member tries to hack into the server in future who got to see the IP address of the server on our computers. Otherwise, if we didnt give the IP, this hacking challenge would not go any further because hacking into gmail would take quite some time assuming its even possible. Moreover, goodluck trying to transfer funds out of our wallet when the actual server is up as the wallet will be locked and the key will be in RAM and not stored anywhere. Same goes for the encryption key too.

Like everyone is already noticing, there is almost no way to find the IP but because we dont know everything, we figured one of you will be able to find a way and this is the reason we are trying to help as much as we can."

Only to make sure your application server which should get hacked is located at Amazon =?

Yes it is on Amazon.

Man, I even gave you guys a netstat example. If you know TOR, you should know default port is 9050. and bitcoind listens to 9050 and that 9050 listens to something else. How will you guys find it if you cant understand something that is already given???

My curiosity brought me back... can't wait to see the solution on how to utilize this "already given" facts. Or is the bitcoind publicly listening on 9050 and all we are supposed to do is portscan the amazon network to find a bitcoind on port 9050?

Your netstat only reveals that what happens on localhost stays on localhost Cool

I'm not a tor expert but isn't the idea of a hidden tor service to be hidden? And any way to trace a hidden service would be a serious major flaw in tor?

Man, I even gave you guys a netstat example. If you know TOR, you should know default port is 9050. and bitcoind listens to 9050 and that 9050 listens to something else. How will you guys find it if you cant understand something that is already given???

Anyways, done for the night. All replies tomorrow.

Part 1 with 1698 entries of a global ipv4 scan of the complete ipv4 space of all currently available online servers worldwide that are listen on port 18333 right at the moment

Part 2 should be ready soon after the scan is complete. So if your ip ends with 13 and is listening on port 18333 the chances are not that bad.

Guys I highly suggest you read what I have written. I have given enough hints till now and now I am not going to correct anyone as that also seems waste to alot of you. Last advice - read what I have written so you dont waste your time.

If I understood it right, you wrote that the IP isn´t findable at the Moment ?!
