Guardio Unveils New Threat: ‘EtherHiding’ Conceals Web2 Malicious Code Within Web3 Smart Contracts

October 13, 2023.

Guardio, a cybersecurity firm, has brought attention to a newly identified threat known as “EtherHiding,” marking a concerning development at the intersection of Web2 and Web3 technologies. In a detailed analysis, Guardio reveals that EtherHiding involves the surreptitious embedding of malicious Web2 code within Web3 smart contracts. This technique poses a serious risk to decentralized applications (dApps) and blockchain networks, as attackers exploit vulnerabilities by concealing harmful code within the seemingly secure environment of smart contracts. The concealment of malicious code within the decentralized infrastructure challenges the traditional security paradigms, highlighting the need for enhanced scrutiny and countermeasures in the evolving landscape of cryptocurrency and blockchain cybersecurity. Developers and users alike are urged to stay informed and adopt proactive security measures to mitigate the potential risks associated with this innovative form of cyber threat.
