Offensive Security for Cryptographic and Network Infrastructure:
Uncovering critical failures before adversaries do

About

Cryptera's Exploit & Protect division operates at the bleeding edge of applied cryptanalysis, blockchain protocol review, and network exploitation simulation. We work with blockchain foundations, financial institutions, payment systems, and identity infrastructure to identify the vulnerabilities that others miss - and help harden them before they’re weaponized.

We bring the mindset of an attacker and the discipline of a sovereign security program. Our focus areas include decentralized systems, consensus mechanisms, cryptographic primitives, messaging protocols, hardware wallets, and identity stacks.

We don’t just look for bugs - we model collapse scenarios.

What we can do

Leverage Our Expertise.
Let’s Build What’s Next.

Work with us

Deep Protocol Review

We examine the underlying logic and mechanisms of decentralized systems to surface design-level vulnerabilities before they become attack vectors:

Full-stack auditing of blockchain consensus, governance, and runtime behavior
Analysis of smart contract logic, validator mechanics, and economic incentives
Vulnerability research into staking, slashing, bridging, and consensus edge cases

Network Layer Exploitation

We analyze how data moves through networks and reveal how adversaries can intercept, spoof, or manipulate communications under realistic conditions:

Man-in-the-middle, message replay, onion routing abuse
Traffic correlation, metadata leakage, relay poisoning
Infrastructure-free mesh and ad-hoc protocol testing under jamming conditions

Applied Cryptanalysis & Identity Infrastructure

We test the integrity of cryptographic systems and identity protocols, exposing weak assumptions and implementation flaws in their design:

Zero-knowledge proof systems and signature schemes
Key recovery risks, key reuse, entropy weakness, misuse of primitives
Identity model validation for sovereign and decentralized ID platforms (DID, ZKID, etc.)

Payments & Financial System Attack Simulation

We simulate real-world threat scenarios targeting critical financial systems - from transactions to wallets to gateways:

Transaction flow analysis across payment rails and gateway infrastructure
Protocol downgrades, logic bombs, and isolation attacks
Mobile, SDK, and wallet surface fuzzing

Our Difference

We focus on deep protocol and cryptographic infrastructure - not just surface-level scanning or generic pen testing. Our researchers have backgrounds in mesh networks, distributed systems, financial cryptography, and advanced persistent threat modeling.We act like the adversary you hope never shows up - and then help you defend against them.

Pay-for-Failure Guarantee

We stand by our ability to find critical issues. If we complete a full scope engagement and do not identify any vulnerabilities of significance, you don’t pay. Simple as that.
