Penetration Testing
— Crypto & Blockchain
Manual validation and exploit-focused Penetration Testing. We help Crypto & Blockchain-based companies proactively secure their digital assets before attackers strike.
Free Scoping CallCrypto & Blockchain Vulnerability Intelligence
Crypto exchanges and DeFi protocols control billions of dollars in digital assets. Smart contract vulnerabilities are irreversible once exploited, making pre-deployment security audits existentially critical.
Reentrancy Attacks in Smart Contracts
Recursive calling vulnerabilities in Solidity smart contracts allowing attackers to drain funds by repeatedly calling withdrawal functions before balance updates complete.
Flash Loan Oracle Manipulation
Price oracle manipulation attacks using flash loans to artificially inflate or deflate asset prices, enabling profitable liquidations and arbitrage exploitation.
Private Key Management Vulnerabilities
Insecure storage and handling of hot wallet private keys, weak entropy in key generation, and insufficient multi-signature enforcement in custody solutions.
Bridge Protocol Exploits
Cross-chain bridge vulnerabilities in validator sets, signature verification, and message relay mechanisms that have accounted for $2B+ in losses.

Frequently Asked Questions
How is the Penetration Testing schedule determined?
After a preliminary analysis where we map all targets, we calculate the man-day effort and present a finalized schedule.
Do you help remediate the vulnerabilities?
Absolutely. Our report includes specific remediation advice tailored to your tech stack and infrastructure.
Are reports valid as legal compliance documents?
Prepared using globally recognized methodologies (OWASP, NIST), our reports act as formal reference documents for auditors.
