Touring the Dark Side of Internet: A Journey through IOT, TOR & DockerAbhinav Biswas
With the advent of IOT, Every 'Thing' is getting Smart, starting from the range of smartwatches, smart refrigerators, smart bulbs to smart car, smart healthcare, smart agriculture, smart retail, smart city and what not, even smart planet. But why is every thing getting smart? People are trying to bridge the gap between Digital World & Physical World by means of ubiquitous connectivity to Internet, and when digital things become physical, digital threats also become physical threats. Security & Privacy issues are rising as never before. What if the microphone in your smart TV can be used to eavesdrop the private communications in your bed room? What if a smart driverless car deliberately crashes itself into an accident? What if you want to be Anonymous over Internet and don't want anybody to track you?
This talk will focus on answering the above questions with a view on 'What are we currently doing to protect ourselves' and 'What we need to do'. What are the new security challenges that are coming up and how privacy & anonymity is taking the lead over security. The talk will also sensitive the audience about the paradigm shift that is happening in IOT DevOps, with help of Docker Containers and how they can be anonymised using TOR.
The document provides an overview of the Tor network, which aims to enable anonymous communication on the internet. It discusses why anonymity is needed, how the Tor network works using onion routing and circuits of routers to hide a user's location and identity, limitations of Tor including slow speeds and vulnerability of exit nodes, licit and illicit uses of Tor for privacy and censorship circumvention as well as illegal activities, and dangers of using Tor including surveillance risks. It concludes that research has made progress on anonymous communication and public interest in privacy tools like Tor is likely to increase.
This document discusses different types of anonymous networks and how they provide anonymity for internet users. It introduces mix networks, peer-to-peer networks and other approaches that aim to hide a user's identity and communications. The document outlines various anonymous network architectures including centralized high-latency systems, centralized low-latency systems, and distributed/pseudo-distributed networks. It also discusses some of the challenges of providing anonymity including various attack approaches adversaries may use to try and de-anonymize networks.
Onion routing is a technique for anonymous communication over a computer network. In an onion network, messages are encapsulated in layers of encryption, analogous to layers of an onion. The encrypted data is transmitted through a series of network nodes called onion routers, each of which "peels" away a single layer, uncovering the data's next destination. When the final layer is decrypted, the message arrives at its destination. The sender remains anonymous because each intermediary knows only the location of the immediately preceding and following nodes.
Onion routing was developed in the mid-1990s at the U.S. Naval Research to protect U.S. intelligence communications online. It was further developed by the Defence Advanced Research Projects Agency (DARPA) and patented by the Navy in 1998. Onion Routing is implemented The Onion Routing project or TOR project.
The document summarizes Tor (The Onion Routing), an anonymizing network that allows users to improve their privacy and security on the Internet. Tor works by routing traffic through several volunteer servers run by others around the world, hiding a user's location and usage from anyone conducting network surveillance or traffic analysis. It enables a wide range of uses including circumventing censorship, protecting government communications, and allowing dissidents and journalists to communicate more safely.
Onion routing and tor: Fundamentals and Anonymityanurag singh
Onion Routing and Tor: Fundamentals and anonymity discusses anonymity on the internet and how Tor works to provide anonymity. It explains that traditional IP addresses and browser tracking can be linked to a user's identity. Tor creates circuits through multiple relay nodes to hide a user's location and communications. Key features of Tor include using volunteer-run relay nodes, protecting against traffic analysis, and enabling hidden services to host anonymous websites. While Tor enhances anonymity, it cannot prevent all timing attacks if the start and end of a user's traffic can be observed.
I2P is an anonymous network layer that provides stronger privacy protections than Tor. It uses garlic routing, message bundling and end-to-end encryption over short-lived tunnels to obscure a user's location and activities. Sites hosted on I2P, called eepsites, can only be accessed by other users on the network. While smaller than Tor currently, I2P offers increased security through its fully distributed architecture with no centralized points of control or surveillance.
This second-generation Onion Routing system addresses limitations in the original design by adding perfect forward secrecy, congestion control, directory servers, integrity checking, configurable exit policies, and a practical design for location-hidden services via rendezvous points. Tor works on the real-world Internet, requires no special privileges or kernel modifications, requires little synchronization or coordination between nodes, and provides a reasonable tradeoff between anonymity, usability, and efficiency.
Tor is an anonymous communication network that allows users to securely communicate on the internet without revealing their location or identity. It works by routing a user's communications through a series of relay servers run by volunteers all around the world, making it difficult to trace the origin or destination of the communications. Tor protects users' privacy and anonymity through its onion routing technique which encrypts and then randomly bounces communications through multiple nodes. While Tor provides anonymity, it can also be used for illegal activities which presents challenges for its widespread adoption and use.
Onion Routing (Tor) is an anonymity network that allows users to securely communicate on the internet without compromising their privacy. It works by routing traffic through several servers, making it impossible for observers to trace the connection back to the user. Tor is the most widely used implementation of the Onion Routing design and improves upon the original design by allowing any server along the circuit to act as an exit point, making it harder to determine where traffic originated. Individuals, organizations, and governments all use Tor to keep communications private.
This seminar discuss about the TOR BROWSER NETWORK TECHNOLOGY. The discussion includes, How it works, its weakness, its advantage, hidden services, about anonymity etc.
Secondary data refers to data that has already been collected by someone else, while primary data is data that is collected by the researcher themselves. Some advantages of using secondary data include not having to reinvent the wheel, saving time and money, and the data may be very accurate if collected by a government agency. However, secondary data can be limited by being outdated, incomplete, or inconsistent over time. Primary data collection allows customizing data to specific research questions but is more time consuming and expensive. Researchers must determine if their question can be answered by existing secondary data or requires new primary data collection.

This document discusses Meek and domain fronting as techniques for circumventing internet censorship. It provides an overview of censorship tools and the arms race between censors and circumvention methods. Meek uses domain fronting to hide proxy traffic by making encrypted requests to CDNs like Google and Cloudflare that appear as normal traffic, making the connections difficult for censors to block without blocking major sites. Meek has been implemented in tools like Psiphon and Tor to provide uncensorable access by tunneling their protocols over domain-fronted connections. While attacks from deep packet inspection are possible, Meek has so far proven very effective at evading censorship.
This document describes the methodology for conducting network penetration tests and web application penetration tests. For network penetration tests, it involves footprinting, scanning and enumeration, vulnerability analysis, exploitation, and reporting. The goal is to identify security vulnerabilities in the network that could be exploited by hackers. For web application tests, it analyzes the application's configuration, authentication, session management, authorization, data validation, web services, and produces a report of findings and recommendations. The overall goal is to evaluate the security of networks and web applications and provide remedies to identified vulnerabilities.
The talk will start explaining how Tor project can help us to the research and development of tools for online anonymity and privacy of its users while surfing the Internet, by establishing virtual circuits between the different nodes that make up the Tor network. Later, we will review main tools for discover hidden services in tor network with osint tools. Finally we will use python for extracting information from tor network with specific modules like stem https://stem.torproject.org/
These could be the main points of the talk:
- Introduction to Tor project and hidden services
- Discovering hidden services with osint tools
- Extracting information from tor network with python
The global Tor network and its routing protocols provide an excellent framework for online anonymity. However, the selection of Tor-friendly software for Windows is sub-par at best.
Want to anonymously browse the web? You’re stuck with Firefox, and don’t even think about trying to anonymously use Flash. Want to dynamically analyze malware without letting the C2 server know your home IP address? You’re outta luck. Want to anonymously use any program that doesn’t natively support SOCKS or HTTP proxying? Not gonna happen.
While some solutions currently exist for generically rerouting traffic through Tor, these solutions either don’t support Windows, or can be circumvented by malware, or require an additional network gateway device.

- Ways enterprises bypass data leakage prevention including encryption and VPNs
- Differences between proxies, Tor, and VPNs and why Tor provides more anonymity
- Options for maximum anonymity hosting and WikiLeaks platforms on darknets
- Using open Wi-Fis or custom configurations as darknet exit nodes
- Digital currencies and tools like OpenTransactions that allow untraceable transactions
- Decentralized portal systems like Osiris and peer-to-peer networks for private file sharing and chat
- The relationship between encryption, anonymity, and enabling free speech
This document provides an overview of basic network security concepts. It discusses what security is, why we need it, who is vulnerable, and common security attacks like denial of service attacks, TCP attacks, packet sniffing, and their countermeasures. It also covers firewalls and intrusion detection systems, explaining what they are used for and how they help address security issues. The document uses examples to illustrate concepts like how firewall rules work and how packet sniffing, man-in-the-middle attacks, and dictionary attacks exploit vulnerabilities.
This chapter reviews basic networking concepts like protocols, ports, and network devices. It discusses how switches prevent flooding attacks and use protocols like STP. Routers are covered, including how they route traffic and use ACLs to filter traffic. Firewalls are also summarized, including the differences between stateful and stateless configurations and how firewall rules work. Network segmentation methods like DMZs, proxies, and VLANs are also introduced.

Setting Up .Onion Addresses for your Enterprise, v3.5Alec Muffett
Onion networking provides an alternative to traditional IP networking by using self-authenticating onion addresses and circuits through the Tor network. Some key aspects of onion networking include:
1) It establishes circuits between clients and servers to transport TCP connections, similar to how IP uses frames and MAC addresses.
2) Onion addresses resolve to introduction points that introduce circuits to rendezvous points for communication, providing redundancy and avoiding single points of failure.
3) While slower than traditional networking due to additional hops, onion networking provides benefits like built-in anonymity, censorship resistance, and lack of single points of control due to its distributed nature.
What is Wireshark?
Wireshark is a free and open-source packet analyzer. It is used for network troubleshooting, analysis, software and communication protocol development, and education.
Wireshark perhaps one of the best open source packet analyzer available for Windows and LINX
Some Important Purpose
Network Administrator used for troubleshoot network problem.
Network security engineer used for examine security problem.
Developer used for debug protocol implementation.
People used for learn protocol protocol internals.
Proxy servers sit between an internal network and an external network. They act as an intermediary for requests from the internal users to hide their IP addresses and improve security. Proxy servers terminate TCP connections, caching frequently requested files to improve performance, and can filter content to enforce security policies. They provide anonymity and security for internal users while allowing access to external networks and resources.
This document provides an overview and introduction to network theory and Java programming. It discusses key topics like network communication models (OSI and TCP/IP), protocols, ports, sockets, firewalls, proxies, and an overview of Java. The document also provides code samples for basic Java socket programming including using ServerSocket for servers and Socket for clients. It explains concepts like connection-oriented and connectionless sockets in UDP and TCP. The objective is to help readers understand network environments and be able to develop basic networking applications in Java.
The document discusses network security vulnerabilities like spoofing and flooding attacks. It covers denial of service (DoS) and distributed denial of service (DDoS) attacks. Firewalls like packet filters and proxies are introduced as a way to limit network access and inspect traffic according to security policies. Intrusion detection systems (IDS) are also mentioned for detecting intrusions through signatures or anomalies.

Shmoocon Epilogue 2013 - Ruining security models with SSHAndrew Morris
This document summarizes how SSH can be used to compromise security in several ways:
1. Authentication can be bypassed by generating a public key on an attacker's machine and transferring it to a victim's machine to allow code execution without a password.
2. SSH allows file transfer and traffic tunneling which can be used to transfer tools, exfiltrate data, and bypass firewalls by tunneling any protocol over an SSH connection.
3. Dynamic tunneling with tools like SOCKS and Proxychains allows running scans, exploits, and other tools through an SSH connection without needing privileged access on the target.

Tor is an anonymity network that allows users to browse the web anonymously. It works by routing traffic through a series of volunteer servers, or relays, that encrypt and then randomly route data in an attempt to make it untraceable. The Tor browser bundles this routing technology to allow users to access the open web as well as "hidden services" anonymously. While Tor provides anonymity, it has some weaknesses including potential traffic analysis of autonomous systems and exit node eavesdropping. The presentation provides an overview of how Tor works and relays, how to use Tor safely, and some common services found on Tor.
What is port forwarding used for?
Port forwarding, also known as port management, allows remote servers and devices on the internet to be able to access devices that are on a private network. If you are not using port forwarding, only devices on that private internal network can have access to each other or your network.

HijackLoader Evolution: Interactive Process HollowingDonato Onofri
CrowdStrike researchers have identified a HijackLoader (aka IDAT Loader) sample that employs sophisticated evasion techniques to enhance the complexity of the threat. HijackLoader, an increasingly popular tool among adversaries for deploying additional payloads and tooling, continues to evolve as its developers experiment and enhance its capabilities.
In their analysis of a recent HijackLoader sample, CrowdStrike researchers discovered new techniques designed to increase the defense evasion capabilities of the loader. The malware developer used a standard process hollowing technique coupled with an additional trigger that was activated by the parent process writing to a pipe. This new approach, called "Interactive Process Hollowing", has the potential to make defense evasion stealthier.
