OSCP+ | Penetration Testing with Kali Linux (PEN-200) Live Online in Bangalore

The opening module covers the core concepts, technologies and good practice of cyber security that the later modules build on.

• How offensive and defensive security relate to each other
• Threats and threat actors, and the difference between risks, threats, vulnerabilities and exploits
• The CIA triad: confidentiality, integrity and availability
• Security principles, controls and strategies, such as layered defence and restricted privileges
• Laws, regulations, standards and frameworks, and career opportunities in the field

You learn to write clear reports that set out each vulnerability, its likely impact and the steps to fix it.

• Taking notes during an engagement and choosing a note-taking tool
• Capturing screenshots as evidence
• Writing an executive summary and a technical summary
• Describing technical findings and recommendations
• When to use appendices, resources and references

This module is about mapping a target before you attack it, with tools such as Nmap and Shodan.

• Passive information gathering and OSINT, including web server and DNS sources
• Port scanning with Netcat and Nmap
• DNS, SMB, SMTP and SNMP enumeration

Scanners such as Nessus and OpenVAS find known vulnerabilities in networks, applications and systems, which shortens the early part of a test.

• How vulnerability scanning works, the types of scan and what to consider before running one
• Installing Nessus, configuring a scan and working with the results
• Authenticated scans and Nessus plugins
• Lightweight scanning with the Nmap Scripting Engine (NSE), including custom NSE scripts

How web applications work, the technologies underneath them and the design weaknesses that give attackers a way in.

• Web application assessment methodology and the OWASP Top 10
• Enumeration tools and the Burp Suite proxy
• Inspecting headers, cookies and source code, and testing APIs
• Cross-site scripting (XSS): the types, basic exploitation and privilege escalation through XSS

The techniques behind common web attacks, mainly injection flaws, and the ways to stop them.

• Directory traversal with absolute and relative paths and encoded characters
• Local and remote file inclusion (LFI and RFI), and PHP wrappers

Attacks on the software that users run themselves, used to compromise their systems and gain access.

• Target reconnaissance and client fingerprinting
• Microsoft Office attacks built on Word macros
• Abusing Windows library files and shortcuts to get code execution

Finding reliable public exploits, judging what they do and using them responsibly in a test.

• The risk of running untrusted exploit code, and why you read it before you run it
• Online exploit resources and Google search operators
• Offline resources: exploit frameworks, SearchSploit and Nmap NSE scripts
• Enumerating a target, choosing a suitable exploit and using it to get a shell

Adapting and customising existing exploits so that they work against the system in front of you.

• Buffer overflow theory at a high level
• Cross-compiling binaries
• Modifying and updating memory corruption exploits
• Fixing web application exploits and troubleshooting common problems with them

How antivirus software detects payloads, and how testers disguise exploits and payloads to behave as a real attacker would.

• Known and unknown threats
• The key components of antivirus software and its detection engines

Finding weak authentication by attacking network logins and cracking captured hashes.

• Attacking SSH and RDP logins and HTTP POST login forms
• Password cracking fundamentals and mutating wordlists
• Attacking password manager key files and SSH private key passphrases
• Obtaining, cracking and passing NTLM hashes
• Cracking and relaying Net-NTLMv2 hashes

Finding and exploiting misconfigurations and vulnerabilities in Windows to gain administrator-level access.

• Windows privileges and access control mechanisms
• Situational awareness and searching a system for sensitive information, including what PowerShell leaves behind
• Automated enumeration tools
• Hijacking service binaries and DLLs, and abusing unquoted service paths
• Scheduled tasks, and abusing privileges to run code as a privileged account

Escalating privileges on Linux systems until you have root access.

• Files and user privileges on Linux, with manual and automated enumeration
