You Should Know
1. Information Gathering & Attack Surface Mapping
The foundation of any security assessment begins with comprehensive reconnaissance. The repository documents an extensive arsenal of OSINT and active reconnaissance tools that security professionals can deploy to map organizational attack surfaces.
Key Tools and Their Applications:
Amass — The OWASP Amass Project performs network mapping of attack surfaces and external asset discovery using open-source information gathering and active reconnaissance techniques. To perform a basic subdomain enumeration:
amass enum -d example.com
ASNLookup & ASNmap — Quickly look up updated information about specific ASN, Organization, or registered IP addresses. Use ASNmap to map organization network ranges:
asnmap -org "Organization Name"
Certificate Transparency Abuse — Tools like `crt.sh` and `CTFR` abuse Certificate Transparency logs to discover subdomains without dictionary attacks or brute force:
Using crt.sh CLI curl -s "https://crt.sh/?q=%example.com&output=json" | jq -r '.[].name_value' | sort -u Using CTFR ctfr -d example.com
DNS Reconnaissance — `dnsx` is a fast and multi-purpose DNS toolkit that allows you to perform multiple DNS queries of your choice with a list of user-supplied resolvers:
dnsx -d example.com -a -aaaa -cname -mx -1s -txt -resp-only
Subdomain Takeover Detection — Use `Aquatone` for domain flyovers and screenshot capture:
cat subdomains.txt | aquatone
Windows Command Equivalent — For Windows environments, PowerShell can perform DNS enumeration:
Resolve-DnsName -1ame example.com -Type A Resolve-DnsName -1ame example.com -Type MX
2. Vulnerability Analysis & Automated Scanning
Once the attack surface is mapped, vulnerability identification becomes the next critical phase. The repository provides comprehensive guidance on using both manual and automated vulnerability discovery tools.
Nuclei — The Vulnerability Scanner
Nuclei is a fast and customizable vulnerability scanner based on a simple YAML-based DSL. It uses templates to detect thousands of known vulnerabilities:
Basic scan against a target nuclei -target https://example.com -t nuclei-templates/ Rate-limited scanning to avoid detection nuclei -target https://example.com -t nuclei-templates/ -rate-limit 5 Custom HTTP headers for testing nuclei -target https://example.com -t nuclei-templates/ -header "User-Agent: Pentest" -header 'X-Red-Team: Assessment' Debugging requests nuclei -l targets.txt -t /path/to/templates/ -debug-req -rl 10
Nikto Web Server Scanner — A classic web server scanner for identifying misconfigurations and outdated software:
nikto -h https://example.com nikto -host 127.0.0.1 -useproxy http://proxy:3128

5. Exploitation & Memory Corruption
Understanding exploitation techniques is essential for both offensive security professionals and defenders who need to understand attacker methodologies.
ASLR (Address Space Layout Randomization) Testing
Check current ASLR status:
cat /proc/sys/kernel/randomize_va_space Values: 0 = disabled, 1 = conservative, 2 = full randomization
Test if a binary is vulnerable to buffer overflow:
./binary `python -c 'print "A"200'` Segmentation fault (core dumped) indicates vulnerability
Test ASLR effectiveness by checking libc address multiple times:
ldd /usr/local/bin/ovrflw | grep libc Run multiple times - different addresses indicate ASLR is active
Disable ASLR for testing purposes:
echo 0 > /proc/sys/kernel/randomize_va_space
Enable ASLR:
echo 2 > /proc/sys/kernel/randomize_va_space
Binary Analysis Tools:
- checksec — Checks executable properties like PIE, RELRO, Canaries, ASLR, Fortify Source:
checksec --file=/path/to/binary
- Ropper — Display information about files and find gadgets to build ROP chains for different architectures (x86/x86_64, ARM/ARM64, MIPS, PowerPC, SPARC64):
ropper --file ./binary --search "pop rdi"
- PwnTools — CTF framework and exploit development library:
from pwn import context.binary = './binary'
6. EDR/XDR Evasion & Defense Evasion
Modern red team operations require sophisticated evasion techniques to bypass Endpoint Detection and Response (EDR) and Extended Detection and Response (XDR) solutions.
AMSI Bypass Techniques — The repository documents multiple AMSI bypass methods and tools like `amsi.fail` that generate obfuscated PowerShell snippets that break or disable AMSI for the current process.
Shellcode Loaders — Tools like `Donut` generate x86, x64, or AMD64+x64 position-independent shellcode that loads .NET Assemblies, PE files, and other Windows payloads from memory:
donut -i payload.exe -o shellcode.bin
EDR Bypass Frameworks — `EDRSandBlast` weaponizes vulnerable signed drivers to bypass EDR detections (Notify Routine callbacks, Object Callbacks, and ETW TI provider) and LSASS protections.
Payload Toolkits — `Freeze` is a payload toolkit for bypassing EDRs using suspended processes, direct syscalls, and alternative execution methods.
Obfuscation Tools — Tools like `Chimera` (PowerShell obfuscation script designed to bypass AMSI and commercial antivirus solutions) and `Invoke-Obfuscation` provide additional evasion capabilities.
7. Cloud & Container Security
The repository addresses cloud and container security with practical hardening guidance:
Device Guard — Hardens against malware by running trusted code only, enforced in Kernel and Userspace (CCI, UMCI, KMCI). UEFI Secure Boot protects BIOS and firmware.
LAPS (Local Administrator Password Solution) — Centralized password storage with periodic randomization, stored in computer objects.
Layered Architecture — The repository recommends a tiered approach:
