// What We Do

Offensive Security Services

We run the same attacks real adversaries use, against your actual environment. No checkbox audits, no generic reports.

Advanced

Red Team Operations

Starting from zero access, we go after your most valuable assets using the same tools and tactics real attackers use. We're testing whether your people, your processes, and your technology can actually catch us in time.

  • Operator-controlled C2 (Cobalt Strike, Sliver, Outflank)
  • Custom implant development with EDR/AV evasion
  • Full Active Directory kill chain: foothold to DA
  • Assumed breach & objective-based scenarios
  • Phishing-led initial access with AiTM & payload delivery
  • MITRE ATT&CK mapped report with detection gaps
Engage Us →

Cloud Security Review

Most cloud breaches happen because of misconfigurations, over-permissioned accounts, and forgotten resources — not zero-days. We look at your cloud the way an attacker would, and connect the dots between low-risk items that automated scanners treat as separate.

  • AWS / Azure / GCP misconfiguration & hardening review
  • IAM policy analysis: over-provisioned roles & priv-esc paths
  • Public exposure audit: storage, snapshots, APIs & databases
  • Azure AD / Entra ID & Conditional Access assessment
  • IMDS abuse, SSRF-to-metadata & container escape scenarios
  • Hardcoded secrets & credential leakage discovery
Engage Us →

Phishing Simulations

MFA is not the end of the conversation. We run phishing campaigns using the same setups threat actors actually use, including proxies that can bypass MFA entirely. After every campaign you get real numbers: who clicked, who submitted credentials, and what to do about it.

  • AiTM credential harvesting — bypasses MFA transparently
  • Device Code phishing targeting Microsoft 365 & Azure
  • Browser-in-the-Browser (BITB) lure pages
  • Spear-phishing with macro-free malicious attachments
  • QR code & SMS-based (smishing) campaigns
  • Full metrics: open rates, click rates, credential submission
Engage Us →

Source Code Review

Automated scanners produce a lot of noise and miss the things that actually matter. We pair tooling with manual review by people who understand how code gets written and how it gets broken, which is how we find the logic flaws and authorization bypasses that tools walk straight past.

  • Business logic & access control flaw analysis
  • Injection vulnerabilities: SQL, SSTI, XXE, deserialization
  • Insecure authentication, session management & JWT handling
  • Hardcoded secrets, API keys & sensitive data exposure
  • Dependency & supply chain vulnerability review
  • Python, Java, C/C++, Go, Bash, PowerShell coverage
Engage Us →

Web App & API Security

Modern applications have a lot of moving parts: multiple frontends, microservices, third-party integrations, public APIs. We test the whole picture manually, connecting findings that look minor in isolation into realistic scenarios that show you the actual business impact.

  • IDOR, broken object-level & function-level authorization
  • OAuth 2.0, SAML & JWT implementation flaws
  • REST & GraphQL API abuse, introspection & batching attacks
  • SSRF, XXE, SSTI & advanced injection chains
  • Race conditions, mass assignment & business logic abuse
  • Full re-test included upon remediation
Engage Us →

Infrastructure Security

From your public perimeter to your internal domain controllers, we map and exploit your infrastructure the way a real attacker would. Every exposed asset gets looked at, exploitable vulnerabilities get prioritized, and you see the full impact of what a network-level breach actually looks like.

  • External attack surface mapping & subdomain enumeration
  • Vulnerability discovery, prioritisation & exploitation
  • Active Directory: Kerberoasting, AS-REP, NTLM relay, ESC attacks
  • SMB & LDAP relay chains, credential coercion (PetitPotam, etc.)
  • Network segmentation & VLAN bypass testing
  • Post-exploitation: credential dumping, persistence & pivoting

// Why Red Team Security

Operator-Led. Adversary-Minded.

This is not a checkbox security firm. Every engagement is led by a practitioner who has spent years developing offensive tooling, getting past enterprise EDRs, and exploiting real production environments.

We have presented at international security conferences, contributed research to the offensive security community, and hold the certifications that actually require you to break things under exam conditions.

◈
Custom Offensive Tooling We build tools for the job, not just run off-the-shelf scanners and call it a test.
◈
Reports Written by Humans Every finding gets clear reproduction steps, real screenshots, and a plain-English explanation of why it matters.
◈
We Test Your Defenses, Not Just Your Code Engagements are designed to trigger your detection and response, not just list open ports.
◈
Support After the Report We stay available while your team works through remediation and re-test the fixes when you are ready.

// Our Process

Engagement Methodology

Here is how a typical engagement runs, from first contact to the final fix verification.

01

Scoping & Rules of Engagement

We agree on clear boundaries, objectives, and what success looks like. Scope, timeline, communication channels, and emergency contacts are locked in before anything starts.

02

Reconnaissance & OSINT

We map your external attack surface using the same sources an attacker would: domains, IP ranges, employee data, technology stack, supplier relationships, and any credentials that have leaked publicly.

03

Attack & Exploitation

We exploit what we find and go as far as the scope allows. Findings get chained together to show what the real damage would be, not just a list of theoretical risks.

04

Reporting & Debrief

You get a technical report for your security team with full reproduction steps, and an executive summary your management can actually read. We also do a live debrief to walk through findings together.

05

Remediation & Re-testing

We are available while your team works through fixes, and we re-test the patched findings at no extra charge to confirm everything is properly resolved.

// Arsenal

Custom-Built Offensive Tooling

We don't rely solely on public tools. Our operator develops and maintains a suite of custom offensive capabilities.

Custom Evilginx3

A heavily modified evilginx3 fork featuring dynamic HTML obfuscation to defeat browser-side static scanning engines, link cloaking, and real-time credential capture piped into Gophish campaign metrics.

AiTMPhishingEvasion
Custom Gophish

A feature-extended Gophish fork with native QR code campaign support, full bidirectional integration with the custom Evilginx3 for AiTM flows, and improved credential export and reporting functionality.

PhishingQRReporting
Web Vulnerability Scanner

Custom multi-stage DAST tool: a Selenium-driven scraper maps all inputs, a fuzzer tests XSS, SSTI, LFI, SQLi, and open-redirect vectors, and an AI-assisted anomaly detector reduces false positives automatically.

DASTAIWeb
Domain Categorisation Tool

Automated tool that submits phishing domains for recategorisation across multiple vendor reputation platforms using Selenium and an integrated captcha-solving engine — keeping infrastructure off blocklists.

OPSECReputationAutomation GitHub ↗
Exploit Research Library

60+ hand-written RCE exploit proof-of-concepts covering CVEs from the last 5 years. Each includes a reproducible vulnerable environment, cross-compiled Linux/Windows binaries, and documented exploitation steps.

ExploitsRCEResearch
Ransomware Proof-of-Concept

Two-variant ransomware PoC developed for red team engagements: a full-UI simulator that replicates real-world ransomware UX and workflow for executive-level impact demos, and a fileless in-memory variant that operates without touching disk to evade EDR-protected environments.
