Welcome to the latest edition of The Week in Security, which brings you the newest headlines from both the world and our team across the full stack of security: application security, cybersecurity, and beyond. This week: NuGet is hit with a malicious typosquatting campaign. Also: A malicious ChatGPT Chrome extension is hijacking Facebook accounts. 

This Week’s Top Story

NuGet software repository targeted with malicious packages

Software supply chain attacks have greatly increased over the past year, especially on open source software repositories. As a result, malicious packages have been downloaded hundreds of thousands of times, causing supply chain attacks globally. Popular repositories npm and PyPI saw an almost 300% increase in supply chain attacks on their platforms in the past four years combined. Other repositories, such as NuGet, which houses .NET code components, haven’t been taken advantage of by attackers… Until now. 

Researchers at JFrog recently discovered a possible first for NuGet: 13 malicious packages with trojan components that compromise a victim’s installation system and download crypto-stealing malware with backdoor functionality. While the malicious packages have been removed from the repository, they were downloaded more than 166,000 times, possibly causing thousands of supply chain attacks. The malicious packages impersonated legitimate software tools like Coinbase and Microsoft ASP.NET, making it easy for developers to accidentally download them. The attackers used typosquatting, in which the name of a popular package is copied and slightly misspelled, to trick developers into downloading these packages. 

This recent campaign discovered by JFrog is significant, considering that typosquatting attacks of this nature have not yet occurred on the platform. This demonstrates that threat actors are continuing to see open source repositories as a worthy landscape for carrying out software supply chain attacks. Also, it shows that even less popular repositories like NuGet, which seemed resilient before, are still susceptible to these kinds of attacks.
