Instead of unverified customer logos or bold marketing claims, we build trust through our published vulnerability advisories, strict operational standards, and transparent methodology.
The core technical and procedural guarantees we provide in every validation cycle.
Every engagement starts with a legally binding NDA. Scopes, vulnerability data, and target assets are kept isolated in encrypted environments and are never exposed.
We do not deliver scanner noise. Every finding contains an executive summary, CVSS scoring, step-by-step reproduction path (PoC), affected lines, and concrete developer instructions.
We do not close findings by assertion. Once patches are deployed, our operators re-run targeted exploits to verify that the attack paths are permanently closed.
We establish secure Signal or Slack channels. Critical alerts are escalated immediately without waiting for the final report, syncing directly with your engineering team.
Verifiable vulnerabilities discovered and responsibly disclosed by the Eresus research team.
Fragnesia (CVE-2026-46300) is a Linux kernel local privilege escalation vulnerability in the XFRM ESP-in-TCP subsystem disclosed May 14, 2026. Third in a series following Copy Fail and Dirty Frag. Discovered by William Bowling (Zellic) and the V12 security team. Patch available.
Dirty Frag (CVE-2026-43284, CVE-2026-43500) is a chained Linux kernel local privilege escalation vulnerability exploiting page-cache write primitives in the xfrm-ESP (IPsec) and RxRPC subsystems. Microsoft Defender confirmed limited active exploitation. Patch available; module blocklist workaround provided.
MCPHub accepts attacker-controlled command and args values during server registration and spawns them through STDIO, enabling full remote code execution on the host.
Examples of attack paths, validation methodologies, and vulnerability classes verified across specific system typologies.
A multi-tenant payment workflow needed validation beyond automated API scanning.
Tested BOLA/IDOR, JWT boundaries, OAuth assumptions, webhook integrity, IAM exposure, and cloud storage paths together.
Mapped auth bypass chains that could expose customer transaction records and resolved them via developer-ready remediation steps.
An agentic system could register internal tools, retrieve documents, and execute production actions without manual verification.
Validated prompt-to-action paths, MCP registration trust, tool execution scopes, approval boundaries, memory leakage, and retrieval abuse.
Hardened prompt boundaries and implemented approval-gate controls for high-risk actions before public release.
Determining whether container and CI/CD configuration drift could enable cluster-wide compromise path.
Reviewed RBAC limits, service account boundaries, ingress rules, secret management, GitOps credentials, and pipeline actions.
Prioritized container escape and lateral movement paths, hardening the target cluster to block lateral exploitation.
A fast-paced development roadmap had accumulated authentication, tenancy separation, and third-party library security debt.
Integrated architecture design review, secure code analysis, pre-commit credentials checks, and offensive testing of critical auth code.
Defined pre-production security gates enabling engineers to validate code security without slowing down sprint velocity.
