But had addresses which did not appear in the network lists. And would not answer pings or other inquiries They were something like a black box A system or device whose contents were unknown
designated for unclassified United States Department of Defense traffic Was split off from the ARPANET in 1983 Direct connectivity between the networks was severed for security reasons. Gateways relayed electronic mail between the two networks In the 1990s, MILNET became the NIPRNET Non-classified Internet Protocol Router Network
of Content Distribution” A 2002 article By Peter Biddle, Paul England, Marcus Peinado, and Bryan Willman Four employees of Microsoft http://msl1.mit.edu/ESD10/docs/darknet5.pdf
upon three assumptions: 1. Any widely distributed object will be available to a fraction of users in a form that permits copying 2. Users will copy objects if it is possible and interesting to do so 3. Users are connected by high-bandwidth channels
that emerges from The injection of objects according to assumption 1 How new objects enter the system And the distribution of those objects according to assumptions 2 and 3 How the objects in the system are distributed
darknet (input) 2. a distribution network that carries copies of objects to users (transmission) 3. ubiquitous rendering devices, which allow users to consume objects (output) 4. a search mechanism to enable users to find objects (database) 5. storage that allows the darknet to retain objects for extended periods of time Functionally, this is mostly a caching mechanism that reduces the load and exposure of nodes that inject objects
computers used for file sharing machines unreachable by other computers on the internet is also used to refer collectively to all covert communication networks Darkweb / Deepweb website content not indexed by search engines Dark fiber unused optical fiber communications infrastructure
to use the internet anonymously. Basically, by joining Tor you join a network of computers around the world that pass internet traffic randomly amongst each other before sending it out to wherever it is going.
tight huddle of people passing letters around. Once in a while a letter leaves the huddle, sent off to some destination. If you can't see what's going on inside the huddle, you can't tell who sent what letter based on watching letters leave the huddle.
technique for anonymous communication Messages are repeatedly encrypted and then sent through several network nodes called onion routers. Each onion router removes a layer of encryption Symmetric keys are pre shared between each pair of routers This uncovers routing instructions for the next hop sends the message to the next router where this is repeated
destination and contents of the message Only starting (ingress) node knows the origin And ending (egress) node knows the destination and the clear text message.
security researcher ran five Tor nodes and collected a list of 100 e-mail credentials server IP addresses e-mail accounts and the corresponding passwords for embassies and government ministries around the globe all obtained by sniffing exit traffic for usernames and passwords of e-mail servers.
embassy the UK Visa Application Center in Nepal the Russian Embassy in Sweden the Office of the Dalai Lama several Hong Kong Human Rights Groups more than 1,000 corporate accounts with passwords
node can read the bytes that come in and out there. Tor anonymizes the origin of your traffic, and it makes sure to encrypt everything inside the Tor network, but it does not magically encrypt all traffic throughout the internet.”
the notion that an eavesdropper cannot easily determine both the sender and receiver of a given message The degree of privacy is generally a function of the number of participating routers versus the number of compromised or malicious routers.
multiple messages together to make it more difficult for attackers to perform traffic analysis Implemented in projects like I2P - Anonymizing overlay network which allows applications to run on top of it Perfect Dark
at Layer 8 Overlaid on top of the 7 layers Just like VPN tunnels IP inside IP Built using VPN’s OpenVPN, Openswan, Vyatta Routers running BGP Quagga, GNU Zebra, OpenBGPD, Vyatta
present applications can use. I2P / IIP fits in between layer 6 and layer 7 Below the application layer Uses garlic routing Currently these services are running over I2P Usenet, E-mail, IRC, Ftp, Http, Telnet Bittorrent, eDonkey, Gnutella It seems all the present network services can run over I2p But the project is still in alpha state
GNUnet is developed by the FSF Free Software Foundation Official GNU project Unlike I2P which is layered Freenet and GNUnet, implement their own applications Currently only file sharing is supported And a trivial chat protocol, not compatible with IRC or XMPP.
of a concept called cryptocurrency first described in 1998 by Wei Dai implemenetd in 2009 by Satoshi Nakamoto uses a distributed database over a p-p network to journal transactions uses cryptography to ensure that bitcoins can only be spent by the person who owns them and never more than once therefore transactions are atomic and irreversible
use of strong public-key cryptography to bring about privacy and freedom It was described by Vernor Vinge as a cyberspatial realization of anarchism relies heavily on plausible deniability to avoid censorship
Attacks on our infrastructure originating from these darknets are possible They are more of a threat to the government than corporations or individuals Anarchy is against government How to defeat these darknets … Traffic analysis, stuff like that
to identify anonymous writers by their style Used a technique called Writeprint which automatically extracts thousands of multilingual, structural, and semantic features to determine who is creating "anonymous" content online. can look at a posting on an online bulletin board, for example, and compare it with writings found elsewhere on the Internet. by analyzing these certain features, it can determine with more than 95 percent accuracy if the author has produced other content in the past.
