Ethereum Smart Contracts based on Blockchain Technology (BT) enables monetary transactions among peers on a blockchain net-work independent of a central  WEBThere are known vulnerabilities in various blockchain ecosystem components. To this end, we perform the file-, text-, and code-level vulnerability analysis as follows There are known vulnerabilities in various blockchain ecosystem components. WEBABSTRACT. Additionally, three real contract-layer real attack events are reproduced by an experimental approach We categorise those incidents against the key cybersecurity vulnerabilities in blockchain technologies; and have developed a taxonomy that captures five types of cybersecurity threats and The objectives of this paper are to determine the security risk of the blockchain systems, analyze the vulnerabilities exploited on the blockchain, and identify recent security challenges that the blockchain faces This field note describes some vulnerabilities observed in smart contracts and node software,  WEBSep,  · We categorise those incidents against the key cybersecurity vulnerabilities in blockchain technologies; and have developed a taxonomy that captures five types of  WEBOct,  · An empirical study on blockchain’s system vulnerabilities from four representative blockchains, Bitcoin, Ethereum, Monero, and Stellar, and obtains WEBArticle #: Date of ConferenceOctober Date Added to IEEE XploreFebruary ISBN Information: Electronic ISBNPrint on Based on this unique dataset, we study three key yet unex-plored aspects of blockchain vulnerabilities, including susceptible blockchain modules, common blockchain vulnerability types, and blockchain-specific patch code patterns. This field note describes some vulnerabilities observed in smart contracts and node software, their exploitation, and how to avoid them, with a focus on the Ethereum ecosystem The security vulnerabilities of blockchain services in the Common Vulnerabilities and Exposures (CVE) and China Nation Vulnerability Database (CNVD) are selected and enumerated.
