Introduction:
The recent Ekoparty 2025 security conference has underscored the critical convergence of offensive security and DevSecOps in the modern threat landscape. This article distills key technical learnings from the event, providing a actionable toolkit of commands and methodologies for security professionals. We will bridge the gap between theoretical knowledge and practical application, covering everything from initial reconnaissance to cloud hardening.
Learning Objectives:
- Master essential command-line tools for penetration testing and security auditing across Linux and Windows environments.
- Understand and implement core DevSecOps principles, including SAST, DAST, and infrastructure-as-code security.
- Develop a methodology for cloud security hardening and container vulnerability mitigation.
You Should Know:
1. Network Reconnaissance & Enumeration
The initial foothold in any security assessment relies on thorough reconnaissance. The following commands, verified on Kali Linux, are indispensable for mapping the attack surface.
Perform a TCP SYN scan on the top 1000 ports with service version detection nmap -sS -sV --top-ports 1000 <target_ip> Enumerate DNS records to discover subdomains and hosts dig any target-domain.com Alternatively, use a subdomain brute-forcing tool amass enum -d target-domain.com Perform a comprehensive vulnerability scan with Nmap NSE scripts nmap -sS -sV --script vuln <target_ip>
Step-by-step guide: Begin with `nmap -sS` for a stealthy SYN scan to identify open ports without completing the TCP handshake. Follow up with service version detection (-sV) to determine what software is running. Use `amass` or similar tools to discover subdomains, which often host less-secure development or staging environments. Finally, leverage the power of the Nmap Scripting Engine (NSE) with the `vuln` category to probe for known vulnerabilities in the discovered services.
2. Web Application Vulnerability Assessment
Web applications are a primary attack vector. These commands help identify common flaws like SQL injection and cross-site scripting (XSS).
Use ffuf for fast directory and vhost fuzzing ffuf -w /usr/share/wordlists/SecLists/Discovery/Web-Content/common.txt -u http://target.com/FUZZ Perform a basic SQL injection test with sqlmap sqlmap -u "http://target.com/page?id=1" --batch --level=1 Scan for XSS vulnerabilities with a dedicated tool xsstrike --url "http://target.com/search?q=query" --crawl
Step-by-step guide: Start by fuzzing for hidden directories and files with `ffuf` to expand the known attack surface of the web application. For any parameter that interacts with a database (e.g., ?id=1), use `sqlmap` to automate the detection and exploitation of SQL injection flaws. The `–batch` flag runs it in non-interactive mode. Concurrently, use a tool like `XSStrike` to crawl the application and test all input fields for reflected and stored XSS vulnerabilities.
3. Privilege Escalation on Linux Systems
Once initial access is gained, the next step is often escalating privileges. These commands help identify common misconfigurations on a Linux host.
Find SUID binaries which may be exploitable find / -perm -u=s -type f 2>/dev/null Check for capabilities on binaries that can grant privileges getcap -r / 2>/dev/null Look for running processes and cron jobs ps aux | grep root crontab -l
Step-by-step guide: After gaining a shell, search for SUID binaries with find. These binaries run with the owner’s privileges (often root), and if they are poorly written, can be exploited. Check for Linux capabilities with getcap, as these can grant a binary specific privileges like reading any file. Finally, inspect running processes and cron jobs to identify any that run with elevated privileges or that you can manipulate.
4. Windows Lateral Movement & Enumeration
Moving laterally across a Windows network requires a deep understanding of Active Directory and built-in tools.
Enumerate domain users and groups net user /domain net group "Domain Admins" /domain Use PowerShell to discover shares and sessions Get-SMBShare Get-SMBSession Dump hashes from the local SAM database for password cracking reg save HKLM\SAM Sam.save reg save HKLM\SYSTEM System.save
PowerShell one-liner to check for token privileges whoami /priv
Step-by-step guide: Use the `net` command to perform basic domain enumeration, identifying high-value targets like Domain Admins. PowerShell cmdlets like `Get-SMBShare` reveal network shares that may contain sensitive data. To extract credentials for pass-the-hash attacks, use the `reg save` command to dump the SAM and SYSTEM hives, which can then be parsed with tools like `secretsdump.py` from the Impacket suite.
5. Integrating SAST into the CI/CD Pipeline
DevSecOps requires shifting security left. Static Application Security Testing (SAST) scans source code for vulnerabilities early in the development lifecycle.
Example GitLab CI pipeline configuration stages: - test - security sast: stage: security image: name: "semgrep/semgrep" script: - semgrep --config=auto . --sarif > semgrep-results.sarif artifacts: reports: sast: semgrep-results.sarif
Running a SAST scan locally with Semgrep semgrep --config=p/ci --config=p/security .
Step-by-step guide: Integrate a SAST tool like Semgrep directly into your CI/CD pipeline configuration file (e.g., `.gitlab-ci.yml` or GitHub Actions workflow). The example above uses the `semgrep/semgrep` Docker image to scan the codebase using a wide range of community-driven security rules (--config=auto). The results are output in the SARIF format, which most CI platforms can parse and display as a security report in the merge request.
6. Hardening Cloud Storage (AWS S3)
Misconfigured cloud storage is a leading cause of data breaches. These AWS CLI commands help audit and harden S3 buckets.
Check the ACL of a specific S3 bucket aws s3api get-bucket-acl --bucket my-bucket-name Apply a bucket policy that denies all non-HTTPS traffic aws s3api put-bucket-policy --bucket my-bucket-name --policy file://secure-bucket-policy.json
Contents of `secure-bucket-policy.json`:
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "EnforceTLS",
"Effect": "Deny",
"Principal": "",
"Action": "s3:",
"Resource": "arn:aws:s3:::my-bucket-name/",
"Condition": {
"Bool": {
"aws:SecureTransport": "false"
}
}
}
]
}
Step-by-step guide: Regularly audit your S3 buckets using `get-bucket-acl` and `get-bucket-policy` to ensure they are not publicly accessible. Proactively enforce security by applying a bucket policy that explicitly denies any request that does not use SSL/TLS (the `aws:SecureTransport` condition). This prevents accidental data exposure through misconfiguration.
7. Container Vulnerability Scanning with Trivy
In a DevSecOps pipeline, scanning container images for known vulnerabilities is non-negotiable.
Scan a local Docker image for vulnerabilities trivy image my-app:latest Scan a container filesystem for misconfigurations trivy config /path/to/your/Dockerfile Integrate scan into a CI script, failing the build on critical vulnerabilities trivy image --exit-code 1 --severity CRITICAL,HIGH my-app:latest
Step-by-step guide: Integrate `trivy` into your build process. Run it against your Dockerfile (trivy config) to catch best-practice violations early. Then, after building the image, scan it (trivy image) against comprehensive vulnerability databases. By using the `–exit-code 1` and `–severity` flags, you can automatically fail the CI/CD build if critical or high-severity vulnerabilities are detected, preventing vulnerable images from being deployed.
What Undercode Say:
- The fusion of offensive security tooling with DevSecOps automation is no longer a luxury but a necessity for building resilient systems. The manual, siloed penetration test is being augmented by continuous, automated security testing embedded in the development workflow.
- The skills gap is not just about knowing how to exploit a vulnerability, but increasingly about understanding how to codify security controls and remediate flaws at scale using infrastructure-as-code and pipeline integrations.
The insights from Ekoparty 2025 reveal a clear trajectory: the modern security professional must be a hybrid, equally comfortable wielding `nmap` in a black-box test as they are crafting a secure Kubernetes `NetworkPolicy` or writing a GitLab CI job to run a SAST tool. The tactical commands for privilege escalation and lateral movement are only half the battle; the strategic victory lies in building systems that are inherently more resistant to those same techniques. This requires a deep cultural and technical shift towards DevSecOps, where security is a shared responsibility and a continuous process, not a final gate.
Prediction:
The techniques demonstrated at leading-edge conferences like Ekoparty will be rapidly weaponized into automated scripts and integrated into popular attack frameworks within 6-12 months. This will lower the barrier to entry for less-skilled attackers, making sophisticated attack chains more common. Consequently, the industry will see a surge in attacks targeting misconfigured cloud-native and containerized environments. The organizations that will successfully mitigate this coming wave are those investing now in automating their defensive controls, embracing DevSecOps, and training their teams on the offensive tactics used by adversaries. The future of cybersecurity is a race between automation in offense and automation in defense.
