Introduction:
As organisations accelerate digital transformation, their attack surfaces expand at an unprecedented rate—the average enterprise now acquires more than 300 new internet-facing services every month. Traditional point-in-time penetration tests, often conducted months apart, leave critical blind spots that attackers can exploit. YesWeHack, a leading offensive security and exposure management platform, is addressing this challenge through a unified, multi-layered approach that combines crowdsourced bug bounty programs, continuous pentesting, autonomous security checks, and vulnerability disclosure policies. At FutureCon Orange County 2026 in Anaheim on 23 July, YesWeHack’s Carlos Torres and Stephen L. will demonstrate how organisations can stay ahead of attackers by moving from periodic audits to continuous, risk-based security assurance.
Learning Objectives:
- Understand the four-phase MAP → TEST → FIX → COMPLY cycle for continuous offensive security
- Learn how to implement multi-layered security testing combining automated checks, human-led pentesting, and crowdsourced bug bounty programs
- Master practical Linux and Windows commands for attack surface discovery, CVE validation, and vulnerability prioritisation
- Explore vulnerability disclosure policies (VDPs) and their role in coordinated vulnerability disclosure frameworks
- Gain actionable insights for integrating continuous security testing into CI/CD pipelines without slowing development
1. Attack Surface Discovery: Mapping the Unknown Unknowns
The first step in any offensive security strategy is knowing what you need to protect. YesWeHack’s Attack Surface Management (ASM) capability provides real-time visibility into internet-facing assets, including web applications, APIs, cloud infrastructure, and mobile apps. This continuous discovery process surfaces the “unknown unknowns” of your digital footprint—assets that may have been forgotten, misconfigured, or shadow-deployed by development teams.
Step‑by‑step guide for attack surface discovery:
Linux – Subdomain enumeration using Amass:
Install Amass go install -v github.com/owasp-amass/amass/v4/...@master Passive subdomain enumeration amass enum -passive -d yourcompany.com -o subdomains.txt Active enumeration with brute force amass enum -active -d yourcompany.com -brute -w /usr/share/wordlists/subdomains.txt
This identifies all subdomains associated with your organisation, many of which may host forgotten or unmonitored applications.
Linux – Port scanning and service fingerprinting with Nmap:
Comprehensive port scan with service detection nmap -sV -sC -O -p- -T4 yourcompany.com -oA scan_results Identify open ports, running services, and OS fingerprints nmap -sS -sV -O -p 80,443,8080,8443 yourcompany.com
Integrate these outputs into exposure management dashboards for continuous monitoring.
Windows – Using PowerShell for asset discovery:
Test-1etwork connectivity and common ports Test-1etConnection yourcompany.com -Port 443 Test-1etConnection yourcompany.com -Port 80 Resolve DNS records Resolve-DnsName yourcompany.com -Type A Resolve-DnsName yourcompany.com -Type CNAME
What this does: These commands map your external attack surface, revealing assets that may be vulnerable to exploitation. Run these scans weekly and submit discovered API flaws via bug bounty programs.
2. Automated Security Checks: Validating CVEs at Scale
Once assets are mapped, organisations need continuous validation against actively exploited vulnerabilities. YesWeHack’s Security Check feature provides automated, continuous validation of CVEs and misconfigurations across selected assets. Each checkpoint ensures that a given vulnerability is not actually exploitable, creating “Detected Issues” findings that help security teams continuously adapt their security posture.
Step‑by‑step guide for CVE validation and tracking:
Linux – Querying CVE databases for specific vulnerabilities:
Using the NVD API to check for specific CVEs curl -s "https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2024-12345" | jq '.vulnerabilities[bash].cve' Check for actively exploited CVEs using known exploit databases curl -s "https://cve.circl.lu/api/cve/CVE-2024-12345"
Linux – Tracking YesWeHack-assigned CVEs:
Query for CVEs assigned by YesWeHack as a CNA python3 bin/search.py -p yeswehack
This lists all CVE records where the assigning CNA is YesWeHack, allowing you to track their specific contributions to the vulnerability database.
Windows – Using PowerShell to check CVE status:
Invoke-RestMethod to query NVD API $cveId = "CVE-2024-12345" $response = Invoke-RestMethod -Uri "https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=$cveId" $response.vulnerabilities[bash].cve | ConvertTo-Json
What this does: These commands help security teams validate whether specific CVEs affect their environment. Organisations can choose which checkpoints to activate and which assets to scan, prioritising remediation based on real-world exploitability.
- Continuous Pentesting: Eliminating False Positives Through Human Validation
Automated scanners generate overwhelming numbers of false positives, leaving security teams with remediation backlogs and time lost to triage. YesWeHack’s Continuous Pentesting service combines asset discovery, automated security checks for active threats, and in-depth manual testing to uncover vulnerabilities across the attack surface—all without slowing down development pipelines. Every finding is manually retested and validated by YesWeHack’s 24/7 triage team of certified specialists before reaching your team, delivering zero noise and zero wasted time.
Step‑by‑step guide for implementing continuous pentesting:
Linux – Automated vulnerability scanning with Nuclei:
Install Nuclei go install -v github.com/projectdiscovery/nuclei/v3/cmd/nuclei@latest Run template-based scanning against targets nuclei -u https://yourcompany.com -t cves/ -t misconfiguration/ -o results.txt Scan with severity filtering nuclei -u https://yourcompany.com -severity critical,high -o critical_findings.txt
Linux – Fuzzing for hidden endpoints:
Directory and file fuzzing with ffuf ffuf -u https://target.com/FUZZ -w /usr/share/wordlists/dirb/common.txt -c -t 200 API endpoint fuzzing with custom wordlist ffuf -u https://api.target.com/v1/FUZZ -w api_endpoints.txt -fc 404
Fuzzing helps uncover hidden API endpoints and directories that may expose sensitive data.
Windows – Using PowerShell for basic vulnerability scanning:
Test for common misconfigurations using Test-Connection Test-Connection -ComputerName yourcompany.com -Count 1 Check SSL/TLS configurations Invoke-WebRequest -Uri https://yourcompany.com -SkipCertificateCheck
What this does: These tools provide continuous, automated vulnerability discovery that complements manual pentesting. When combined with human validation, they eliminate false positives and deliver only actionable, prioritised findings.
- Grey-Box Bug Bounty Programs: Testing Beyond the Perimeter
While black-box testing simulates external attacker perspectives, grey-box testing provides hunters with partial system knowledge—typically credentials to specific environments—enabling deeper exploration of post-authentication flaws, API misuse, business logic errors, and misconfigurations. YesWeHack’s platform provides Credentials Management features to create, assign, or revoke accesses to hunters on specific scopes.
Step‑by‑step guide for setting up a grey-box bug bounty program:
- Navigate to Admin Panel: Go to “Admin Panel” → “Edit” the program of your choice
-
Configure hunting requirements: Go to the “Hunting Requirements” section and indicate scopes with limited access
-
Create credential pools: Click “Add credentials pool” and select either:
– Email Credentials: Hunters request credentials through the platform, providing an email address. You create accounts within your system and make them available
– Login Credentials: Hunters receive credentials from an existing batch of accounts provisioned and imported into the platform
- Define access levels: Create pools offering different access rights (e.g., Basic, Advanced, Admin)
-
Activate the pool: Click “Activate pool” in the Admin Panel/Credentials tab
Best practice: Provide two test accounts per hunter—this is especially useful when testing access control issues where one account attempts to access data belonging to another.
What this does: Grey-box testing enables hunters to find vulnerabilities that would be invisible from the outside, including IDOR (Insecure Direct Object References), broken access controls, and business logic flaws that could lead to data breaches.
- Vulnerability Disclosure Policies: A Passive yet Critical Layer
Unlike active security testing, a Vulnerability Disclosure Policy (VDP) creates a secure, anonymous channel for anyone—security researchers, customers, or even well-intentioned users—to report potential vulnerabilities responsibly and legally. VDPs are advocated by regulatory agencies including NIST, ENISA, and CISA, and prescribed through ISO 29147 and ISO 30111 standards.
Step‑by‑step guide for implementing a VDP:
- Choose your VDP solution (requires Business Unit Owner or Manager permissions):
– Standard VDP: Set up a dedicated webpage hosted on YesWeHack
– Embedded VDP: Embed your VDP in an iframe on a webpage of your choice
– Featured VDP: Showcase your VDP to the YesWeHack hunter community in a dedicated platform tab
- Publish the policy: Define scope, disclosure guidelines, and legal protections
-
Manage incoming reports: Retrieve reports directly from the YesWeHack interface with the same templates, features, workflows, and dashboards as bug bounty reports
-
Respond and remediate: Acknowledge reports, validate findings, and coordinate remediation
What this does: A VDP encourages early and legal disclosure, helping organisations identify and fix vulnerabilities before malicious actors can exploit them. It builds trust with customers and stakeholders while demonstrating commitment to cybersecurity.
6. AI-Powered Security Testing: The Human-in-the-Loop Advantage
As organisations embed LLMs, autonomous agents, and MCP servers into exposed systems, AI components increasingly handle sensitive data and interact with backend infrastructure. YesWeHack’s Agentic Pentest leverages AI agents shaped by bug hunting experience to uncover vulnerabilities, validate exploitability, and prove real-world impact in your environment.
Step‑by‑step guide for AI security testing:
- Deploy flexible testing approaches: Run black-box, grey-box, and white-box pentests on demand
-
Test for AI-specific vulnerabilities: Focus on prompt injection, insecure output handling, excessive agency, and model denial-of-service
-
Validate the foundation: Test conventional vulnerabilities in web applications, APIs, and supporting infrastructure—AI deployments often introduce new API endpoints, data flows, and third-party dependencies that expand the attack surface
-
Generate audit-ready deliverables: Access fully reproducible PoCs for each finding, executive summaries, and audit reports for specified scopes
Linux – Testing API endpoints for common vulnerabilities:
Test for IDOR using Burp Suite or custom scripts
Example: Check for insecure direct object references
curl -X GET "https://api.target.com/v1/users/123/profile" -H "Authorization: Bearer $TOKEN"
Test for SSRF via document ingestion features
curl -X POST "https://api.target.com/v1/summarize" -d '{"url":"http://169.254.169.254/latest/meta-data/"}'
SSRF through document ingestion features can reach internal services and expose cloud metadata.
What this does: AI-powered testing combines the speed of automation with human creativity and persistence, uncovering sophisticated vulnerabilities and complex exploit scenarios that fully automated approaches miss.
7. Risk-Based Prioritisation and Compliance Reporting
With vulnerabilities aggregated from multiple testing sources, organisations need a unified approach to prioritisation and compliance. YesWeHack’s Vulnerability Center automatically calculates priority scores built from CVSS baselines and enrichment signals. Patching tools allow customers to use targeted WAF rules to block exploitation within hours of a new finding.
Step‑by‑step guide for vulnerability prioritisation:
- Centralise all findings: Aggregate vulnerabilities from Bug Bounty Programs, Continuous Pentest, Autonomous Pentest, and VDP into a single pane of glass
-
Apply risk-based prioritisation: Prioritise based on asset value, severity, and exploitability—not just CVSS scores
-
Generate compliance reports: One-click generation of audit-ready reports for ISO 27001, SOC 2, PCI DSS, DORA, and NIS2
-
Demonstrate continuous compliance: Use unified dashboards and executive summaries to show ongoing security posture to auditors and stakeholders
Linux – Automating compliance reporting:
Generate vulnerability summary reports Integrate with SIEM/SOAR workflows for automated ticketing python3 generate_compliance_report.py --framework iso27001 --output report.pdf
What this does: This approach turns fragmented testing into measurable security progress, helping teams discover exposure, validate risk, prioritise remediation, and generate audit-ready evidence over time.
What Undercode Say:
- Continuous security testing is no longer optional. The average organisation acquires over 300 new internet-facing services monthly—point-in-time pentests cannot keep pace. Organisations must adopt continuous, multi-layered testing approaches that combine automation with human expertise to eliminate blind spots.
-
Human validation remains irreplaceable. While AI accelerates testing, the most sophisticated vulnerabilities still require human creativity, persistence, and contextual understanding. The “humans in the loop” model—combining AI-assisted researchers with experienced triage teams—delivers the highest signal-to-1oise ratio.
Analysis: The shift toward continuous offensive security represents a fundamental change in how organisations approach vulnerability management. Traditional annual or bi-annual pentests are giving way to always-on testing models that adapt to evolving attack surfaces. YesWeHack’s MAP → TEST → FIX → COMPLY framework provides a practical roadmap for this transition, integrating automated discovery, crowdsourced testing, and risk-based prioritisation into a unified platform. The company’s CREST accreditation, ISO 27001 certification, and EU-hosted GDPR-compliant infrastructure position it well for regulated industries. With over 150,000 ethical hackers and customers including Louis Vuitton, Ferrero, the European Commission, Tencent, and L’Oréal, YesWeHack demonstrates that crowdsourced security testing has matured from a niche practice to an enterprise-grade security solution.
Prediction:
+1 The convergence of AI-powered security testing and crowdsourced human expertise will accelerate vulnerability discovery cycles from weeks to hours, dramatically reducing mean time to remediation.
+1 Regulatory frameworks including DORA, NIS2, and the Cyber Resilience Act will increasingly mandate continuous security testing and vulnerability disclosure policies, driving enterprise adoption of platforms like YesWeHack.
-1 Organisations that fail to adopt continuous security testing will face widening security gaps as attack surfaces expand and attackers leverage AI to automate vulnerability discovery and exploitation.
+N The bug bounty market will continue consolidating around platforms that offer integrated solutions—combining ASM, automated scanning, continuous pentesting, and VDP—rather than point solutions for individual testing types.
-P The European Commission’s selection of YesWeHack as its preferred bug bounty provider signals growing government recognition of crowdsourced security testing as a critical component of national cybersecurity infrastructure.
