Security Testing in the Real World for Smart Contracts, dApps, and Blockchain Infrastructure
Orasec provides result oriented penetration testing of blockchain services. We help to find vulnerabilities that lead to the exposure of smart contracts, which are the decentralised applications, and also the blockchain platforms along with the, supporting infrastructures, which are other points of, compromise in the security. We do not stop at mere coverage of the features but rather by integrating the certified penetration testers, quite challenging methodologies, and attack simulation, we disclose security weaknesses that exclusively affect the firms...
Our blockchain penetration testing spans the entire range of Web3 settings from EVM compatible chains such as Ethereum, Polygon, and BNB Chain to Solana, Cosmos, and enterprise grade private and consortium blockchain deployments. Our testers are equipped to find vulnerabilities in the consensus mechanism, paths for front running and MEV attacks, gas manipulation exploit tactics, and NFT contract security issues at each and every layer of your protocol. No matter if you are operating a DeFi platform, an NFT marketplace, or a permissioned enterprise chain, we identify the attack vectors that have potentially become real threats without having to learn the hard way.
Blockchain environments are high value targets. Smart contract logic, token economics, decentralised application interfaces, wallet integrations, and supporting infrastructure create an expansive and complex attack surface that demands security testing built specifically for blockchain architectures not generic assessments repurposed for decentralised environments.
Blockchain implementations are capable of carrying large sums of money, customer information, and essential business logic that is directly embedded in unalterable smart contracts. One loophole in a smart contract or a decentralised application can lead to losing funds that can't be recovered, exploiting the protocol, and the complete takeover of the platform without any possibility of going back the transactions or fixing the code that has been deployed without migration.
Orasec blockchain penetration testing approach examines all the layers of your blockchain setting from the logic behind the smart contract and token mechanics to the decentralised application interfaces, wallet integrations, and the cloud infrastructure that is supporting you.
Smart contracts encode business rules, financial logic, and access controls directly on chain. Reentrancy vulnerabilities, integer overflow and underflow, access control failures, logic flaws, and flash loan attack vectors create paths to irreversible fund drainage, governance manipulation, and complete protocol compromise.
DeFi protocols, token contracts, and governance systems implement complex economic logic that creates exploitable attack surfaces beyond standard code vulnerabilities. Price oracle manipulation, flash loan exploits, governance attack vectors, and economic logic flaws allow attackers to drain protocol funds and manipulate platform behaviour at scale.
Blockchain applications expose web and mobile interfaces connecting users to on chain functionality. Insecure wallet connections, front end vulnerabilities, transaction manipulation, and malicious signing request injection create paths to user fund theft and unauthorised transaction execution.
Private key management, wallet integrations, and signing mechanisms are critical attack surfaces in blockchain environments. Insecure key storage, weak entropy in key generation, compromised signing workflows, and malicious transaction approval flows create direct paths to asset theft and account compromise.
Cross chain bridges and interoperability protocols handle significant asset value across blockchain networks. Insecure bridge validation logic, oracle manipulation, replay attack vulnerabilities, and cross chain message forgery create high value attack targets that have resulted in some of the largest blockchain exploits on record.
Blockchain nodes, RPC endpoints, indexing services, and cloud infrastructure support decentralised application operations. Misconfigured nodes, exposed RPC interfaces, insecure APIs, and cloud infrastructure weaknesses create paths from infrastructure compromise to platform disruption and sensitive data exposure.
We conduct comprehensive security assessment of smart contract code across Solidity, Rust, Vyper, and other contract languages. Testing covers reentrancy, access control failures, integer arithmetic vulnerabilities, logic flaws, gas optimisation weaknesses, upgrade mechanism risks, and contract interaction attack paths across all deployed and pre deployment contract code.
Our testers assess decentralised finance protocols for economic attack vectors including flash loan exploits, price oracle manipulation, liquidity pool vulnerabilities, governance attack paths, and token mechanic abuse. Testing simulates real world DeFi attack scenarios to identify exploitable protocol logic before deployment or at risk post deployment code.
We conduct full stack security testing of decentralised applications including web and mobile interfaces, wallet connection implementations, transaction signing workflows, API security, and backend infrastructure. Testing identifies vulnerabilities allowing transaction manipulation, fund theft, and unauthorised platform access.
Our testing evaluates wallet integration security, private key management practices, signing mechanism implementations, and key storage controls for weaknesses that allow unauthorised transaction signing, key extraction, and asset theft across custodial and non custodial wallet architectures.
We assess cross chain bridge implementations for validation logic vulnerabilities, oracle manipulation risks, replay attack opportunities, message forgery weaknesses, and economic exploit paths that create high value attack vectors across bridge infrastructure and connected blockchain networks.
Our testing evaluates blockchain node configurations, RPC endpoint security, indexing service controls, and supporting cloud infrastructure for misconfigurations, exposed interfaces, and access control weaknesses that create paths to platform disruption and data exposure.
First, the thorough mapping of smart contracts, protocol architectures, decentralized application interfaces, wallet integrations, bridge infrastructure, and other supporting systems are carried out to visualize all possible exploitable points within the blockchain system.
Contract source code as well as bytecode are examined to identify potential vulnerabilities such as, reentrancy, access control loopholes, arithmetic errors, logic weaknesses, and unsafe external call patterns. Both machine driven and human expert review are combined to cover the possibility of any vulnerability.
Flash loan attack, price manipulation, governance abuse, and other economically motivated reasoning paths which are usually missed by the automated tools are explored during the financial aspects of protocol, token functions, governance, and other related parts assessments.
By means of proof of concept development in test environments, the vulnerabilities found are verified, thus real time exploitability is confirmed and the financial and operational impacts are shown before publishing the results.
Typical penetration testing methods are utilized for testing the infrastructure, decentralized application interfaces, APIs, and wallet integrations while being also modified for blockchain connected application environment.
Each of the findings comes with a detailed report that contains vulnerabilities ranked by risk, proof of concept of exploit evidences, attack path descriptions, and remediation plans with priorities for smart contract development and blockchain operation practices in view.
