gAtO tHiNkInG - anonymity serves different interest for different user groups; To a private citizen it’s privacy, to a business it’s a network security issue. A business needs to keep trade secrets or have IP (knowledge base data-centers), communicate with vendors securely and we all know that business need to keep an eye on there competition – the competition can check your stats

(http://www.alexa.com/siteinfo/uscyberlabs.com) and check on how your business is doing, what keywords your using, demographics of users hitting your site—— by the way in the Tor-.onion network a web site/service cannot be monitored unless you want it…
How would a government use a ToR-network I’m asked all the time —
// if I was an (agent/business-person)state actor doing business in China (and other countries too) well I would use a ToR-.onion connection to keep my
business private from a government that is know to snoop a bit on travelers to their country. The fact is governments need anonymity for their security -think about it “What does the CIA Google for?” Maybe they us ToR??? But this is about Hidden services right.
What is a hidden service in ToR-.onion network?
SImply put it’s a web site/service, a place in the ToR network were we have a service like:
- Search Engine
- web / pop3 email
- PM Private Messages
- Drop Box’s
- Bulletin Boards BBS
- Image Boards
- Currency exchange
- Social Networks
- Micro-Blog -
Hidden Services are called hidden, because your website’s IP in ToR is hidden- they cannot see the IP of your server — they can’t track you- if they can’t find you how are they gonna hack you???? Sorry I had to say that -((more about that later)). Now how do I keep this secret (my IP) and let you the user use my services. In the normal web if your in uscyberlabs.com your on my site,— my server -you can do a whois and get my IP and geo-location— then you can attack my website with dDoS and other IP attack vectors, you also get my location so you can physically find me- my server/my website – maybe go dumpster diving in the trash and get my company secrets— mAyBe sI – nO,
Well in the ToR-.onion network you the client ask the business website if they can use the websites service / then decide and start a handshake to a rendezvous POINT to meet —we meet at an OR ((onion relay))-a rendezvous POINT) not at my server/ my IP — so your never ever on the business site/server when your in onionLand, you can’t do a whois and get my IP because we meet at an OR, you cannot find my geo-location…..
We have heard of the killings of Iranians and Syrian rebels being killed in todays news, when an Iranian rebel is fighting for his and his families life if they(the government) finds his IP or the IP of the website he visited // they will hunt that person down and the Iranian police/government will kill the whole family sometimes. So keeping an IP from someone is not an evil act it is an act of privacy for safety on both sides the client and the business.
you need to look at Figure 2 to explains this better:
Now let’s focus on R2 OR the yellow key. That’s the spot were you(your company’s hidden website) and your client meet — I know it’s a sneaky way of doing business but once again if they can’t get to your IP at least that is one attack vector that can’t be used to hack you or ddos you. OK they can still hack you but it’s software then. How it’s all done – the magic —the technical thingy to this is below —/this is just an outline of events of the client /hidden web/service protocol:
I goes something like this –
- ESTABLISH RENDEZVOUS cell
- INTRODUCE2 cell
- INTRODUCE ACK cell.
- INTRODUCE2 cell
- RENDEZVOUS1 cell
- sends a RENDEZVOUS2 cell Chat
- sends a RENDEZVOUS2 cell Blog
- RENDEZVOUS ESTABLISHED cell
1. Whenever the rendezvous point receives a RELAY_COMMAND_RENDEZVOUS1 with the same cookie as the OR sent in the RELAY_COMMAND_INTRODUCTION1 cell it logs the reception and the IP address of the immediate transmitter of the cell. At the same time, the OR middle node monitors the circuits passing through it. Whenever it receives a DESTROY cell over a circuit it checks:
1) whether the cell was received just after the rendezvous point received the RELAY_COMMAND_RENDEZVOUS1 cell;
2) if the next node of the circuit at the middle node coincides with the previous node of the circuit at the rendezvous point;
3) whether the number of forwarded cells is exactly 2 cells up the circuit and 52 cells down the circuit.

People ask me how can these hidden services be attacked???
It’s all the same as in the surface web you find the software the hidden service is using /// let’s say Worpress (or flatPress) if they use an old version with vulnerabilities then, that site can be hacked by traditional hacking attack vectors— gAtO can’t wait till USCyberLabs.com will have a sandbox in the .onion were we can have a honeypot for people to hack and learn from. (we need Funding for these project donate please – we will share) gAtO has not tried Backtrack 5 on ToR-.onion network – mAyBe sI -nO – uscyberlabs.com has been hacked a few times already and is consistently fighting bot’s and spammer, it goes on and on.everywhere-.-.-.-
Here are some technologies used in the ToR-.onion network:

Snapp BBS works fine in OnionLand - http://4eiruntyxxbgfv7o.onion/ -
PHP BBS – http://65bgvta7yos3sce5.onion/
Nginx is a free, open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server. – http://ay5kwknh6znfmcbb.onion/torbook/
Anyway I hope this open up the mystery of a hidden service in ToR – it’s just a website, you go to a rendezvous point and do your business — your IP and the business IP are totally secure. No digital breadcrumbs. Now a word to the wise in the ToR-.onion network you have some very tech savvy people and some are very stupid be a critical-cyber user always -gAtO oUt.
