Hardware security testing 101 (Null - Delhi Chapter)
Arun Mane is the founder and director of AmynaSec Labs. He is a security speaker and trainer who has presented at many conferences including Defcon, Blackhat, Nullcon, and HITB. His areas of expertise include security testing of IoT devices, connected vehicles, medical devices, and industrial control systems. Some common issues he finds include devices being publicly accessible, having backdoors, hardcoded credentials, and crypto or web application management problems. His testing methodology involves assessing web and mobile applications, embedded device communications, hardware testing through reverse engineering, and analyzing communication protocols and stored data.
Osint primer
This document outlines an agenda for a presentation on open-source intelligence (OSINT) gathering techniques. The agenda includes an introduction to OSINT, different types of intelligence gathering, a scenario example, OSINT gathering tactics and tools like Shodan, TheHarvester and Google dorks, applications of OSINT, a demonstration, references for OSINT, and a conclusion. Key OSINT tools that will be demonstrated include Twitter, Shodan, TheHarvester and Google dorks for gathering information from public online sources.
SSRF exploit the trust relationship
This document provides an overview of server-side request forgery (SSRF) vulnerabilities, including what SSRF is, its impact, common attacks, bypassing filters, and mitigations. SSRF allows an attacker to induce the application to make requests to internal or external servers from the server side, bypassing access controls. This can enable attacks on the server itself or other backend systems and escalate privileges. The document discusses techniques for exploiting trust relationships and bypassing blacklists/whitelists to perform SSRF attacks. It also covers blind SSRF and ways to detect them using out-of-band techniques. Mitigations include avoiding user input that can trigger server requests, sanitizing input, whitelist
Nmap basics
Nmap is a network scanning tool that can perform port scanning, operating system detection, and version detection among other features. It works by sending TCP and UDP packets to a target machine and examining the response, comparing it to its database to determine open ports and operating system. There are different scanning techniques that can be used like TCP SYN scanning, UDP scanning, and OS detection. Nmap also includes a scripting engine that allows users to write scripts to automate networking tasks. The presentation concludes with demonstrating Nmap's features through some examples.
Metasploit primary
The document provides an introduction and overview of the Metasploit Framework. It defines key terms like vulnerability, exploit, and payload. It outlines the scenario of testing a subnet to find vulnerabilities. It describes the main features of msfconsole like searching for modules, using specific modules, and configuring options. It promotes understanding and proper use, emphasizing that Metasploit alone does not make someone a hacker.
Api security-testing
1) The document provides guidance on testing APIs for security weaknesses, including enumerating the attack surface, common tools to use, what to test for (e.g. authentication, authorization, injections), and demo apps to practice on.
2) It recommends testing authentication and authorization mechanisms like tokens, injections attacks on state-changing requests, and how data is consumed client-side.
3) The document also discusses testing for denial of service conditions, data smuggling through middleware, API rate limiting, and cross-origin requests.
Introduction to TLS 1.3
TLS 1.3 is an update to the Transport Layer Security protocol that improves security and privacy. It removes vulnerable optional parts of TLS 1.2 and only supports strong ciphers to implement perfect forward secrecy. The handshake process is also significantly shortened. TLS 1.3 provides security benefits by removing outdated ciphers and privacy benefits by enabling perfect forward secrecy by default, ensuring only endpoints can decrypt traffic even if server keys are compromised in the future.
