- Minimize financial losses by stopping the attack in its tracks.
- Preserve critical evidence for forensic analysis and potential legal action.
- Establish a secure command center to coordinate all response efforts effectively.
Smart Contract Exploit Analysis
We perform a deep-dive forensic analysis of the compromised smart contract code. Our experts identify the exact vulnerability exploited, such as reentrancy, integer overflow, or flawed logic, to understand the root cause and develop a secure patch.
- Gain a precise understanding of the attack vector to prevent re-exploitation.
- Develop and deploy a verified, secure patch for the vulnerability.
- Provide a detailed technical report for developers and stakeholders.
On-Chain Forensics & Asset Tracing
Using advanced blockchain analysis tools and proprietary AI, we follow the trail of stolen funds across multiple chains and through complex obfuscation techniques like mixers and privacy coins. Our goal is to track assets to an identifiable endpoint, such as an exchange.
- Create a clear, visual map of the flow of stolen funds.
- Identify wallets and services used by the attacker for potential freezing.
- Collaborate with global exchanges and law enforcement to intercept assets.
Private Key Compromise Recovery
When administrative or multi-sig keys are compromised, we execute a pre-planned strategy to regain control. This often involves a race against the attacker to move remaining funds to new, secure wallets and revoke compromised permissions.
- Secure remaining assets before they can be exfiltrated by the attacker.
- Establish a new, robust key management and storage protocol.
- Investigate the source of the key compromise (e.g., phishing, malware).

- Prepare your leadership for media inquiries and community AMAs.
Flash Loan Attack Mitigation
Flash loan attacks are a unique DeFi threat. We analyze the complex chain of transactions used to manipulate prices and drain liquidity pools, then help you implement architectural changes, such as using decentralized oracles like Chainlink, to prevent future economic exploits.
- Understand the precise mechanism of the economic exploit.
- Implement robust price oracle solutions to resist manipulation.
- Redesign protocol mechanics to be resilient against flash loan attacks.
Oracle Manipulation Analysis
When an attacker manipulates a price oracle to exploit a protocol, we investigate the source of the faulty data. We determine whether the oracle itself was compromised or if it was fed incorrect information, and recommend more resilient, decentralized oracle solutions.
- Pinpoint the failure point in your data feed architecture.
- Transition to more secure and manipulation-resistant oracle designs.
- Implement circuit breakers to halt protocol activity during extreme price volatility.
Rug Pull & Malicious Actor Investigation
In the event of a suspected rug pull or internal theft, we conduct a discreet investigation. We combine on-chain forensics with off-chain intelligence gathering to identify the malicious actors and provide evidence to support legal action and asset recovery efforts.
- Uncover the identities of anonymous or pseudonymous bad actors.
- Compile a comprehensive evidence package for law enforcement.
- Assist in global legal efforts to hold perpetrators accountable.
Wallet Security Assessment & Recovery
We respond to incidents involving compromised user wallets, whether through phishing, malware, or social engineering. We assess the attack vector, assist users in securing their assets, and provide guidance on improving wallet security practices across your community.
- Educate your user base on safe wallet and seed phrase management.
- Identify and shut down phishing sites and malicious DApps targeting your users.
- Implement platform-level features to warn users of suspicious transactions.
