Frequently Asked Questions About Yenn503
FAQPage SchemaWhat tasks can I perform using Yenn503's skills?▼
You can execute red team attacks (Kerberoasting, DCSync, Pass-the-Ticket, EternalBlue), test web and API flaws (SQL injection, SSRF, BOLA, JWT confusion, XSS), perform digital forensics (memory, disk, network, Windows artifacts), analyze malware (Ghidra, YARA, JADX), and prioritize vulnerabilities with EPSS, CVSS, KEV, and SSVC.
Who are these skills designed for?▼
They target red team operators, penetration testers, SOC analysts, DFIR investigators, vulnerability management engineers, and threat intelligence analysts. Skills map to MITRE ATT&CK, D3FEND, NIST CSF, and NIST AI RMF, supporting detection engineering, purple team exercises, and executive threat reporting.
How do I run these skills in practice?▼
Each skill is a self-contained folder with YAML frontmatter defining name, description, domain, tags, and framework mappings. Most run on standard security distributions using open-source tooling such as Metasploit, Nmap, BloodHound, Volatility 3, Wireshark, and Burp Suite; AV-evasion skills specify a windows-operator execution environment.
Are Yenn503's skills free and open source?▼
Yes. Nearly all skills carry the Apache-2.0 license, while the AV-evasion payload-preparation skills (MultCheck, gocheck, BOAZ) are MIT licensed. There is no cost to use, modify, or redistribute them, though offensive skills require authorized engagement scope.
What prerequisites do these skills require?▼
Prerequisites depend on the subdomain: Active Directory skills need domain-joined lab access and tools like Impacket or Mimikatz; forensics skills need memory dumps, disk images, or EVTX logs; cloud skills need AWS credentials for Pacu, ScoutSuite, or Cartography; web testing skills assume Burp Suite or OWASP ZAP interception proxies.
