Fundamentals of network hacking

Hardening is a conference of Computer Security, created by Prof. Giampaolo Bella of University of Catania to talk of the way to harden the computer that we use every day. In each edition there are different arguments of Internet/Computer Security. In this edition (29 may 2017) we have talked of Intrusion Detection Systems and Intrusion Prevention Systems (IDS/IPS), show examples of attacks and applications of these technologies.

This document discusses WPA exploitation in wireless networks. It begins by explaining basic wireless networking concepts like WiFi, MAC addresses, and SSIDs. It then describes how wireless networks are vulnerable due to weak encryption methods like WEP. The document outlines stronger encryption methods like WPA and WPA2, but notes they can still be cracked with tools if a weak password is used. It proceeds to explain how tools like Aircrack-ng, Reaver, and John the Ripper can be used to crack wireless network encryption keys through techniques like packet sniffing, dictionary attacks, and exploiting WPS pins. In the end, it emphasizes the importance of using long, complex passwords to keep wireless networks secure.

The document discusses cybersecurity issues related to IoT devices. It begins by describing the 2016 Mirai botnet attacks, which exploited vulnerabilities in IoT devices like IP cameras and DVRs to take down major websites. The document then analyzes the current security situations of IoT, finding that many devices have vulnerabilities due to a lack of focus on security by manufacturers. It also notes that IoT devices could potentially be used as "weapons of mass destruction" due to their ubiquity, connectivity and potential access to users' daily lives. The rest of the document examines common vulnerabilities and attack vectors in IoT devices.

Matthieu Faou, ESET After having tracked Turla's activities for several years, we now have a unique understanding of their Tools, Tactics and Procedures (TTPs). Turla, also known as Snake, is an espionage group known for targeting governments, diplomats and militaries all around the world. One of their first documented campaign was against the US military ten years ago and they are still very active. In early 2018, the group broke the news for having successfully breached the German Foreign Office. Some details quickly leaked in news outlets. Turla operators were in the German government network since the end of 2016 and they used a backdoor fully controlled by emails. As no public information were available online, we started analysing the so-called Outlook Backdoor. During our investigation, we were able to identify other important victims such as two Ministries of Foreign Affair in Europe and a large defense contractor. In this talk, we will present a detailed analysis of this malware, which is a full-featured backdoor targeting email clients. Its main target is Microsoft Outlook but it can also interact with The Bat!, an email client widely used in Eastern Europe. To interact with Microsoft Outlook, it leverages the Messaging Application Programming Interface (MAPI). The commands are received through specially crafted PDF attachments that are then decoded and interpreted by the backdoor. There is no strong authentication to verify the identity of the command sender. Thus, anybody understanding the command format would be able to control the compromised machines. It leads to additional security risk for the victims. The malware also exfiltrates highly-sensitive data such as the outgoing emails sent by the infected user. The hardcoded e-mail address used for exfiltration was registered at a popular European free email provider. We will present the analysis of the complex structure that embeds the commands. We will also provide a demo showing it is possible to fully control an infected machine by just sending an email with a PDF attached. This unusual way of communication for a backdoor helps the attackers to blend in the normal network traffic and bypass security monitoring solutions. We will also present older versions of this backdoor, as we were able to trace it back as early as 2013. Finally, we will discuss possible mitigations and methods to detect this backdoor.

The document discusses vulnerabilities in wireless network selection that can be exploited to attack clients. It describes how an attacker can spoof disassociation frames to force clients to rescan and discover preferred networks, then create a rogue access point with the same SSID to get clients to associate with the attacker's network instead of secure networks. It also demonstrates attacks on Windows and MacOS wireless configuration using tools like KARMA to target and compromise clients.

The document proposes a new stealth command-and-control technique for botnets that leverages browsers and honest users. It would work by having the botmaster deploy a malicious website that visitors spread commands to bots from as they browse the site. This avoids direct communication between the botmaster and bots, makes bot detection difficult, and scales well based on number of website visitors. The document also discusses how bots could send stolen data back through spam emails encrypted with the botmaster's public key.

Aircrack-ng is a suite of tools used to recover wireless encryption keys. It consists of a detector, packet sniffer, and cracker for WEP and WPA/WPA2-PSK encryption. It works with wireless network interfaces in monitor mode to sniff 802.11 traffic. Aircrack-ng can recover WEP keys by capturing packets with airodump-ng and then using statistical attacks like PTW or FMS/Korek cracking methods to determine the encryption key from the captured initialization vectors.

Hey guys Find my presentation of "Hacking Wireless Network" that i dilivered in Null Delhi Meet . Give your reviews regarding it . Thanks Mandeep

GSM networks are compromised for over five years. Starting from passive sniffing of unencrypted traffic, moving to a fully compromised A5/1 encryption and then even to your own base station, we have different tools and opportunities. A Motorola phone retails for only $5 gives you the opportunity to peep into your girlfriend's calls. RTL-SDR retails for $20 which allows you to intercept all two-factor authentication in a medium-sized office building. Lastly, USRP retails for $700 and can intercept almost everything that you can see in 2G. But who cares about 2G? Those who are concerned switched off of 2G. AT&T is preparing to switch off all its 2G networks by the end of 2016. Even GSMA (GSM Alliance) admitted that security through obscurity is a bad idea (referring to COMP128, A5/*, GEA algorithms and other things). 3G and LTE networks have mandatory cryptographical integrity checks for all communications, mutual authentication both for mobile devices and base station. The opportunity to analyze all protocols and cryptographical primitives due to their public availability is important. However, the main problem is that we do not have calypso phones for 3G. We do not have cheap and ready to use devices to fuzz 3G devices over the air. Or do we? What about femtocells? Perhaps telecoms are to fast to take their guard down with security considerations embedded in 3G/4G? Users can connect to femocells. and have access the Internet on high speeds, make calls, ect.. Why don't we abuse it? Yes, there is already research that allows you to gain control over femtocell. There is also research that allows sniffing calls and messages after gaining control. But all such solutions are not scalable. You are still bound to the telecom provider. You still have to connect to a VPN - to a core network. You have to bypass location binding and so on. Perhaps there is an easier solution? Parhaps we can create UMTS-in-a-box from readily available femtocell and have them available in large quantities without telecom-branding? We already know. We will tell the whole story from unboxing to proof-of-concept data intercept and vulnerabilities in UMTS networks with all your favorite acronyms: HNB, SeGW, HMS, RANAP, SCTP, TR-069.

WPA3 provides several security improvements over WPA2: 1. It uses a more secure handshake called Simultaneous Authentication of Equals (SAE) that is resistant to offline dictionary attacks. 2. It enables encryption for open WiFi networks through Opportunistic Wireless Encryption (OWE) without requiring a pre-shared password. 3. It supports connecting devices without displays through the Device Provisioning Protocol (DPP) using QR codes and other contactless methods. 4. It enhances cryptographic strength with a 192-bit security suite aligned with government standards.

Presented at NZISIG on Tuesday 26th February 2019. "WPA3: What is it good for? (With a little bit of Bluetooth and a soupçon of GPS)" I offered this talk to Purplecon but they didn't want it so you're getting it instead. Since it's been a few months I've added some other stuff on the end. Overview of existing issues in WAP, WPA, WPA2 and WPS Skateboarding dog story WPA3 improvements: - Password protection - Preshared keys (Simultaneous Authentication of Equals - SAE) - CNSA - Opportunistic Wireless Encryption (OWE) - Wifi Easy Connect Bluetooth - Direction finding - End to end security GPS - 6th April could get interesting.

This document summarizes the top 10 internet security vulnerabilities presented by Randy Marchany at a computing conference. It discusses each vulnerability in the list, including BIND vulnerabilities that allow hackers to control nameservers, CGI script vulnerabilities that can be used to modify websites, and RPC vulnerabilities that permit remote access to systems. It provides solutions for securing systems from these common threats.

The document provides instructions on techniques for cracking wireless network security, including both WEP and WPA encryption. It discusses using tools like aircrack-ng to capture packets, perform injection attacks like deauthentication, ARP replay, and fragmentation. Both simple techniques without injection, like capturing packets over time, and more advanced techniques using packet injection methods are covered. The goal is to obtain enough encrypted packets or keystream fragments to crack the network encryption key.

This document discusses cracking WEP secured wireless networks. It begins by explaining that WEP is an outdated protocol with known weaknesses that can be cracked within minutes using readily available software. It then provides details on WEP authentication methods and how the encryption works. The main weakness discussed is that the 24-bit initialization vector is not long enough to ensure uniqueness, allowing the key to be cracked. The document concludes by demonstrating how to enable monitor mode, attack a target network to capture packets, and use those packets to crack the WEP key in minutes using aircrack-ng software on BackTrack Linux. It advises moving to more secure WPA or WPA2 encryption.

The document discusses exploiting vulnerabilities in wireless routers that have USB ports for sharing storage and printers. It describes conducting attacks against a D-Link wireless router to steal data, delete data, and implant backdoors by accessing the shared USB flash drive and printer through the router's vulnerable SharePort technology. The attacker scans the wireless network, identifies the router and connected USB devices, and then explores ways to hack into the shared resources and conduct unauthorized activities.

The document summarizes a presentation given by Santhosh Kumar and Anamika Singh on analyzing router vulnerabilities and the WiHawk router vulnerability scanner. The presentation covered analyzing sample routers to find issues, open source tools for firmware analysis, demonstrating exploits found, and the lack of responses from some vendors. It also described the WiHawk scanner which automates checking routers for common vulnerabilities and issues like default credentials, backdoors, and more.

"In the past two years, smart speakers have become the most popular IoT device, Amazon_ Google and Apple have introduced their own smart speaker products. Most of these smart speakers have natural language recognition, chat, music playback, IoT device control, shopping, and so on. Manufacturers use artificial intelligence technology to make smart speakers have similar human capabilities in the chat conversation. However, with the smart speakers coming into more and more homes, and the function is becoming more powerful, its security has been questioned by many people. People are worried that smart speakers will be hacked to leak their privacy, and our research proves that this concern is very necessary. In this talk, we will present how to use multiple vulnerabilities to achieve remote attack some of the most popular smart speakers. Our final attack effects include silent listening, control speaker speaking content and other demonstrations. And we're also going to talk about how to extract firmware from BGA packages Flash chips such as EMMC, EMCP, NAND Flash, etc. In addition, it contains how to turn on debug interfaces and get root privileges by modifying firmware content and Re-soldering Flash chips, which can be of great help for subsequent vulnerability analysis and debugging. Finally, we will play several demo videos to demonstrate how we can remotely access some Smart Speaker Root permissions and use smart speakers for eavesdropping and playing voice."

There is a big bunch of tools offering HTTP/SSL traffic interception. However, when it comes to penetration tests of specialized embedded software or thick clients, we often encounter proprietary protocols with no documentation at all. Binary TCP connections, unlike anything, impossible to be adapted by a well-known local proxy. Without disassembling the protocol, pentesting the server backend is very limited. Though, based on our experience, it very often hides a shameful secret - completely unsecured mechanisms breaking all secure coding practices. To demonstrate, we will show a few case-studies - most interesting examples from real-life industry software, which in our opinion are a quintessence of "security by obscurity". We will challenge the security of proprietary protocols in pull printing solutions, FOREX trading software, remote desktops and home automation technologies.
