A scoped, evidence-based engagement to identify, prove and remediate exploitable vulnerabilities.
Covering your application, cloud infrastructure and protocol surface. Every finding is reproduced end-to-end by a senior security engineer with a validated code-level fix, not just scanner output.
What sets this engagement apart
Conventional penetration testing allocates a fixed number of consultant hours and samples what a tester can reach. NeuraCryption couples elastic automated exploration with senior engineering verification.
Full codebase, not a sample
Traditional testing allocates a fixed window of consultant hours and samples a fraction of endpoints. Our methodology maps the entire codebase and infrastructure before manual testing begins, so coverage is an architectural guarantee rather than a function of available hours.
Days, not months, to first finding
Because fuzzing harnesses and exploit candidates are generated against the full attack surface from day one, our engineers review and reproduce verified candidates almost immediately, rather than spending the first two weeks mapping attack surfaces manually.
Cryptography as a specialty, not a gap
Most firms that test a web application cannot meaningfully evaluate a signing protocol, a threshold cryptography library, or smart contract session delegation. We built our methodology specifically around this class of target, and our track record reflects it.
A validated fix, not just a finding
A report that identifies an issue and leaves the fix to your engineering team is an incomplete deliverable. We validate a code-level remediation for every confirmed finding against the exact environment that proved the exploit, so your team deploys a tested change.
Every engagement is backed by reproducible evidence: a working proof of concept, a root cause traced in your own source code, and a validated fix your engineers can deploy with confidence.
Demonstrated track record
A sample of confirmed vulnerabilities from recent engagements, displayed by class and severity rather than client identity. Several remain in active responsible disclosure. Full technical dossiers and CVSS vectors are available under non-disclosure.
| Vulnerability Class | Domain | Weakness & Technical Detail | Severity | Evidence |
|---|---|---|---|---|
| Cryptographic nonce reuse in a multi-party signing system | Digital asset custody (MPC / threshold EdDSA) | CWE-323 Reused nonce across signing blocks, allowing private key derivation from observed signatures. | Critical | |
| Unauthenticated XML external entity injection | Open-source e-commerce REST API | CWE-611 Unrestricted entity resolution on an unauthenticated endpoint exposing server filesystem. | High | |
| Signature identity confusion in session authorization | EIP-7702 smart wallet session delegation | Auth Flaw Struct hash bound to the wrong signer identity, enabling full session takeover. | Critical | |
| Non-standard structured-data array encoding | EIP-712 signing implementation | Spec Deviation Specification deviation forcing blind signing on the primary transaction path. | High | |
| Weak client-side randomness in authentication nonce generation | Web3 authentication SDK (Sign-In with Ethereum) | CWE-338 Non-cryptographic PRNG used for a security-critical replay mitigation token. | High | |
| Signed integer overflow across a cross-language FFI boundary | Multi-party computation library (Go / C++ bridge) | CWE-190 → CWE-122 Undersized heap allocation followed by linear memory overwrite. | Critical |
What these findings mean in practice
Every item above was identified in production or near-production code that had already passed its author's test suite. None produced an unhandled exception, crashed a daemon, or triggered an alert upon discovery. We specialize in vulnerabilities that are silent by design and leave zero trace until exploited. Left unaddressed, these issues enable private key reconstruction from recorded signatures, server-side arbitrary file reads exposing root credentials, unauthorized wallet delegation, or linear heap overwrites dumping sensitive process memory.

Who we are and how we test
A concentrated unit of offensive security engineers, applied cryptographers and machine learning practitioners operating together on every engagement.
Evidence, not scanner output
Every finding in a NeuraCryption assessment carries a working, deterministic proof of concept, an architectural root cause traced into source code, and a validated code patch. Nothing is reported until it has been reproduced end-to-end in an isolated environment by a senior engineer.
Automated candidate generation
Automated fuzzing harnesses execute across every real entry point identified during codebase mapping on isolated Google Cloud compute. Fine-tuned exploit models propose candidate attack chains and are cross-checked independently with XBOW before handoff to human engineers.
How an engagement runs: seven stages end to end
Scoping and rules of engagement
We agree on target inventory, authorized testing windows, testing techniques, and direct technical escalation contacts in writing before executing any probe.
Reconnaissance and mapping
External attack surface mapping runs concurrently with full code and infrastructure dependency mapping, ensuring manual testing begins from a ranked ledger of real risk rather than a checklist.
Automated testing and candidate generation
Fuzzing harnesses run against discovered entry points on isolated Google Cloud infrastructure, with fine-tuned models and XBOW independently generating and validating exploit candidates.
Manual exploitation and reproduction
A senior offensive engineer manually reproduces every candidate that passes automated triage against a clean target build, writing each proof of concept by hand.
Severity rating and reporting
Every confirmed finding is scored under CVSS 3.1, mapped to relevant CWEs, and documented with root cause analysis, reproduction steps, and business impact readable by engineers and executives alike.
Remediation support and patch validation
We supply and validate a code-level fix for every confirmed finding against the specific exploit that proved it, staying available to your developers throughout implementation.
Retest and closure
A dedicated retest cycle verifies that each deployed fix completely closes the vulnerability without creating secondary attack surfaces, concluded by an executive and technical debrief.

The fastest way to evaluate a security firm is a finding, not a reference call.
We propose a scoped, time-boxed proof-of-value engagement against a single application, service or repository of your choosing, with zero obligation to proceed further. You will receive the exact deliverable standard of a full engagement: a reproduced finding, a CVSS score, a root cause traced in your own code, and a validated fix.
If the work meets your expectations, we build the broader scope and engagement plan together from there.
