A malicious package impersonating Stripe's official library was uploaded onto the NuGet Gallery, allowing attackers to steal sensitive data from unsuspecting developers who may have inadvertently downloaded it. Learn more about this latest software security threat and how it can be prevented.
The NuGet Gallery was targeted by a typosquatting attack, where a malicious package masqueraded as a legitimate library from financial services firm Stripe. The malicious package, StripeApi.Net, was downloaded over 180,000 times across 506 different versions before being discovered and removed. The package contained code that replicated the functionality of its legitimate counterpart but also collected and transferred sensitive data back to attackers. Developers may experience no apparent issues with their applications after unknowingly downloading and integrating malicious packages. The incident highlights the importance of rigorous security practices and ongoing vigilance in software development environments. The attack marks a shift in tactics, techniques, and procedures (TTPs) employed by malicious actors, expanding beyond specific sectors to broader vulnerabilities.
The world of software security is a complex and ever-evolving landscape, where threats come in many forms. In recent times, the cybersecurity community has witnessed an increase in typosquatting attacks, where malicious actors create fake software packages that mimic legitimate ones, often with devastating consequences. The latest such attack to gain attention is the one targeting the NuGet Gallery, a popular repository of open-source software libraries and tools.
On February 16, 2026, a user named StripePayments uploaded a malicious package codenamed StripeApi.Net onto the NuGet Gallery, masquerading as Stripe.net, a legitimate library from financial services firm Stripe. The package had been created with the intention of impersonating the genuine article, utilizing an identical icon and README file to gain credibility among unsuspecting developers. Furthermore, the threat actor behind this campaign artificially inflated the download count for the malicious package, which resulted in over 180,000 downloads across 506 different versions. Notably, each version was downloaded roughly 300 times on average.
The malicious StripeApi.Net package contained code snippets that replicated the functionality of its legitimate counterpart but also included modifications that allowed it to collect and transfer sensitive data, including the user's Stripe API token, back to the attackers. The interesting aspect of this attack is that the compromised library remained fully functional in terms of compiling and running applications, with users unaware that their applications were secretly being exploited.
Petar Kirhmajer from ReversingLabs explained that the discovery and removal of the malicious package was a quick response by their team. They discovered it "relatively soon" after its initial release, thus preventing any substantial damage to be inflicted upon unsuspecting developers who might have unintentionally downloaded this fake library.
In recent months, there has been an increase in attacks leveraging bogus NuGet packages that target different sectors, including the cryptocurrency ecosystem, aimed at facilitating wallet key theft. The emergence of typosquatting as a security threat highlights the importance of rigorous security practices and ongoing vigilance in software development environments.
Developers who unknowingly download and integrate such malicious packages will likely experience no apparent issues with their applications compiling and running properly. However, this lack of visibility might be deceiving, as sensitive data is being secretly copied and exfiltrated by malicious actors.
The incident serves as a stark reminder of the ever-evolving nature of cyber threats and underscores the need for developers to maintain stringent security protocols when incorporating external libraries into their projects. This includes verifying the authenticity of packages through reputable sources before integrating them into the development workflow.
Furthermore, the attack marks an interesting shift in the tactics, techniques, and procedures (TTPs) employed by malicious actors. In this instance, rather than focusing solely on wallet key theft within the cryptocurrency sector, attackers have opted to expand their reach beyond that niche. This could signal a broader trend in cybercrime, where different sectors are becoming increasingly vulnerable due to various factors.
The discovery of such malicious software packages highlights the importance of staying vigilant and proactive in safeguarding against emerging threats. By understanding the tactics employed by malicious actors and adopting robust security measures, developers can minimize the risk of falling prey to these types of attacks.
The rise of typosquatting poses significant challenges for cybersecurity teams as they strive to protect against an increasing array of threats. While it is still early to fully comprehend the full scope of this trend, its impact on software security cannot be overstated. As such, staying informed about emerging vulnerabilities and adopting a proactive approach to security best practices will be crucial in countering these evolving threats.
