Web3 Job Scam Uses Malicious GitHub Repo to Steal Crypto Data

A recent cybersecurity investigation revealed a sophisticated scam targeting Web3 job seekers, uncovered by security firm SlowMist. The scam involved a fraudulent team impersonating a Ukrainian Web3 group that lured a candidate to clone a malicious GitHub repository during an interview process. The repository contained code designed to steal sensitive data, including browser information and potential access to cryptocurrency wallet secrets [4]. A vigilant job candidate declined the request, prompting further analysis that confirmed the presence of malicious code. Once executed, the code would have installed backdoors and dependencies capable of exfiltrating data such as mnemonic phrases and Chrome extension storage to attackers' servers [4].

The scheme exemplifies the growing threat of social engineering in the Web3 hiring landscape. Fraudsters have increasingly exploited trust in job opportunities to execute cyberattacks, leveraging platforms like GitHub—commonly used in technical interviews—to deliver malware under the guise of legitimate tasks [4]. The attackers cloned a public repository and altered its code to include malicious payloads, a tactic that exploits the perceived legitimacy of open-source platforms [4]. This method allows scammers to bypass initial suspicion and gain unauthorized access to victims’ systems.

The incident raises concerns about the security posture within the Web3 industry, particularly as decentralized tools and open-source infrastructure become more widely adopted [4]. The attackers may have used a fabricated Ukrainian identity to obscure their real location, making it more difficult to track and prosecute them [4]. SlowMist emphasized the need for caution when handling unverified code, especially during job interviews or technical evaluations [4]. The firm advised organizations to implement strict verification protocols and ensure that all repositories used during the hiring process are from trusted sources.

For individuals, the warning is clear: avoid executing code from unverified or unknown sources [4]. The exposure of this scam highlights the urgent need for greater transparency and security measures in the Web3 job market. As the sector continues to grow, incidents such as these underscore the importance of robust cybersecurity practices and continuous education for both employers and job seekers [4]. The case serves as a cautionary tale about how cybercriminals are evolving their tactics to exploit trust and technical curiosity within the decentralized ecosystem [4].
