Wireless technology is inherently insecure in general, however this presentation details some unconventional attacks that have been around for years but are still incredibly effective. Discussing the basics of AP cloning, abusing captive portals, and more.
With the 'rise of containers' comes also the rise of container platforms. And while Docker is the way to do things for now, Podman has also been gaining traction as the new kid on the block especially after being somewhat embraced by RedHat and Fedora. Being new also comes with lack of heavy scrutiny and audit on the security side of things. Once you start integrating other protocols and pieces that compliment each other, such as Varlink, boundaries become fuzzy. Rather than focus on container breakouts, which are also very important, we'll focus on how Podman and Varlink interoperate and the authentication and security implications as such. We'll look at the remote API capabilities, secure configurations and how certain setups and projects out there by default can be vulnerable to compromise. By the end of the talk, we will have discussed various bugs, issues and hardening techniques around deploying Podman and Varlink together and if you don't know a lot about containers, you'll learn a bit along the way.
Why and How to use Onion Networking - #EMFCamp2018Alec Muffett
Outlining the hows and whys of using Onion Networking to connect apps, devices and tools securely over the Internet, without suffering blocks, NAT issues, or many forms of security woe.
The document discusses the dark web and anonymity networks like Tor. It provides an overview of Tor, how it works to anonymize users, and some of the common tools used to access Tor networks and hidden services. It also discusses some of the challenges of anonymity like timing attacks and de-anonymization efforts by law enforcement, such as the takedown of Freedom Hosting and arrest of the alleged operator of the Silk Road dark web market.
The document summarizes Dan Kaminsky's talk at Black Hat 2007 about exploiting the DNS rebinding vulnerability to bypass firewalls and access internal networks from external web browsers. It describes how DNS rebinding works by abusing the same-origin policy to treat websites with different domain names but the same IP address as coming from the same origin. It then outlines several ways an attacker can force a domain to resolve to different IP addresses and use this to tunnel network traffic over the browser.
This document summarizes Dan Kaminsky's 2007 talk at Black Hat about exploiting vulnerabilities in the DNS system and web browser security policies to enable arbitrary TCP and UDP access from within a web browser. Kaminsky describes how controlling DNS responses allows an attacker to bypass firewalls and access internal networks by manipulating the browser's view of domain names and IP addresses. He then outlines his proof-of-concept attack software called "Slirpie" that implements a VPN-like tunnel using only a compromised web browser.
Your data is much safer at home than it is letting some corporation "take care of it" for you, right? Security reviews for some of the top vendors' devices reveal many interesting findings. Like everything else, there are bugs. But knowing what kinds of bugs and how the vendors have responded will allow you to better understand the impact of plugging these devices into your network. Jeremy will show you just how low access control and least privilege are their list of priorities. He'll also explore the amount of test collateral and debug interfaces sloppily left shipping to consumers. From remote roots to stealing social network tokens to just plain weird stuff, he'll expand on how it's not just about what they do, but also what they don't do. And, he'll give you some useful guidelines on how to close the gaps yourself.

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.
SWAT Style – Live Network Crypto Hacking and Exploitation by Kevin Cardwell a...EC-Council
In todays IT security world, we accept and embrace that the technology is constantly changing, we are very often still amazed at the rapid growth of the technology evolution and how it has far superseded beyond expectations, whilst thinking about the potential uses of this new technology we get excited and then it hits us! What about the security implications for our organization?? Holy Crap what did you say about SS7?
In this presentation, Wayne will take you through some real live demonstrations of Network Crypto Hacking and Exploitation using the latest custom built, SWAT (Special Weapons and Technology) cyber-warfare hacking tools.
To help us defend against the latest threats, that sends our risk rating scores off the chart? We do as we have always done! Research the threat viability, learn and deploy defense and mitigation options. For this very reason its imperative for us to stay up-to date with new emerging threats tactics.

This is a presentation on exploiting Null Byte VM. Null Byte VM is an vulnerable vm available on vulnhub.In this presentation I had exploited vm with various tools available on kali linux and then escalated privileges to become root.In this CTF challenge we have to find a flag i.e. proof.txt.
The document discusses different eras of software deployment:
1. The shared hosting era involved editing files, uploading, and refreshing the browser frequently with many issues.
2. The dedicated server era used Linux distros like Debian and involved more command line work like sudo and vim but still had restart issues.
3. The cloud era saw the rise of tools like Capistrano, Vlad, and Mina to automate deploys but still had restart problems.
4. Every era had issues with daemons not running, crashes, and bugs after restarts due to a lack of process supervision. Runit and systemd help address this by making applications into supervised services.

TakeDownCon Rocket City: WebShells by Adrian CrenshawEC-Council
The document discusses various techniques for gaining remote access to websites through automated collection of remote file inclusion (RFI) vulnerabilities and web shells. It provides examples of PHP code that can be used to upload files, execute system commands, and create backdoors. It also lists sources for common web shells and techniques for obfuscating shell code, communicating stealthily, and restricting access to authorized users only. The document is an educational overview of RFI exploitation and automated web shell collection and management.
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 document discusses various techniques used by hackers during different stages of hacking, including gathering information about a target system, performing reconnaissance to identify open ports and services, and ways to hide one's online identity and location.
- It provides details on how to find a target's IP address, trace an IP to determine location, use tools like ping sweeps and traceroute to gather network information, and use proxy servers, VPNs or HTTP tunneling to circumvent restrictions.
- The techniques discussed aim to educate on hacking methodology while distinguishing "hackers" who test limits from actual "crackers" who intend harm. It cautions that directly hacking systems without permission would be illegal.
Sharing the whole journey experience. Starting with the handover of the keys of the pandora box, wandering around the deep dark forest of uncertainty and instability of the rushed deployed systems. Trying to declutter and reach a stable stage where the order reigns over chaos, where the poor guy can finally sleep at night and the pager eventually goes silent for a while. At the end we'll be reaching the so-desired level of confidence to not be worried about experimenting, changing things and upgrading infrastructure.
Cross Context Scripting (XCS) is a type of XSS (Cross Site Scripting) injection which occurs from an untrusted zone, typically a web page on the Internet into the context of a trusted browser zone.
XSS injection in a trusted browser zone can be 'lethal', as injected payload runs as privileged code. No SOP (Same-Origin Policy) restrictions are enforced and direct interfacing with the underlying OS is possible.
To exploit such bugs, there is no need to use ROP gadgets, spray the heap or attempt other complex techniques. At the opposite, only few elements are required for a successful exploit, such as the right injection point and a tailored exploit payload.
This presentation will examine XCS in details and will provide a demonstration of XCS exploits of both unpatched and patched vulnerabilities in Firefox, Opera, Maxthon and Avant browsers.

IBM X-Force Threat Intelligence Index 2017Jie Liau
The IBM X-Force Threat Intelligence Index 2017 document summarizes key cybersecurity trends and events from 2016. More than 4 billion records were leaked in 2016, a 12% decrease in attacks from 2015 but a 48% decrease in security incidents. Major events like the Panama Papers leak and power outages in Ukraine impacted governments and critical infrastructure. Ransomware and DDoS attacks increased in scale and frequency, with attacks exceeding 1 terabit per second. The top vulnerabilities exploited were injection flaws, buffer overflows, and password brute forcing. Commercial malware and cybercrime expanded into new areas while targeting key industries.
This document discusses different generations of denial of service (DoS) attacks and provides examples of each type:
1. Layer 4 DDoS attacks involve thousands of attackers bringing down a single site, such as a large DDoS against Github originating from China.
2. Layer 7 DoS attacks can bring down a single site with only one attacker, exemplified by the Slowloris attack.
3. Link-Local DoS attacks allow one attacker to bring down an entire network through techniques like IPv6 router advertisement spoofing, as demonstrated in the document.
