Supply Chain Attack Strikes Roblox Developers via npm Packages
Userlevel 7

The problem here is a supply chain attack on the npm package repository targeting Roblox developers. Malicious packages were uploaded to npm, specifically the noblox.js package, which were disguised as legitimate packages used by Roblox developers. These malicious packages have the capability to deploy an open-source information stealer called Luna Token Grabber on systems belonging to Roblox developers. 


Breach of trust

The attack involves abusing the trust that developers have in the npm package repository. Developers rely on these repositories to download and use open-source packages in their projects, and they may not always thoroughly inspect the code or consider the security implications.

Data theft

Luna Token Grabber is designed to steal credentials and tokens from web browsers and Discord. This can lead to unauthorized access to user accounts and potentially sensitive data, including personal information

Multi-stage attack

The attack involves multiple stages, with sophisticated obfuscation mechanisms. This makes it challenging to detect and mitigate, and it can evolve over time, increasing the risk to developers

Reputation damage

Such supply chain attacks can damage the reputation of legitimate package maintainers (e.g., noblox.js) if users mistakenly associate the attack with the legitimate package.


The attack relies on typosquatting, where malicious packages have names similar to legitimate ones, tricking developers into downloading them


How Threat Modeling Can Help


Threat modeling is a structured approach to identifying and mitigating security threats and vulnerabilities in a system or software application. In this context, threat modeling can help address the problem.


Regulatory compliance

Threat modeling helps ensure compliance with relevant data protection and cybersecurity regulations. It identifies vulnerabilities and threats that might lead to non-compliance and helps design security measures to meet legal requirements.

Data privacy

By identifying potential threats like data theft, threat modeling aids in safeguarding sensitive user and company data. Compliance with data privacy laws, such as GDPR or CCPA, is essential, and threat modeling helps establish measures to protect data.

Prioritize mitigation

Threat modeling allows for the prioritization of security mitigations based on the identified threats and vulnerabilities. For example, it may recommend enhancing package verification procedures on npm.

Contractual obligations

Organizations often have contractual agreements with suppliers or customers that include security clauses. Threat modeling assists in fulfilling these obligations by ensuring the security of the supply chain and npm packages, reducing the risk of legal disputes.

Documentation and reporting

Threat modeling results can be used to document security efforts and demonstrate due diligence. This documentation can be essential in case of legal inquiries or audits, providing evidence of proactive security measures.

Design resilience

Threat modeling can lead to the design of more resilient systems by considering security controls and measures to detect and respond to supply chain attacks. For example, npm could implement stronger package signing and verification mechanisms.

Incident response planning

Threat modeling can help in creating incident response plans for scenarios like supply chain attacks, ensuring that the organization is prepared to respond effectively in case of an attack.


Threat modeling can play a crucial role in identifying, assessing, and mitigating security threats associated with the npm package repository and similar supply chain vulnerabilities. It helps organizations and developers proactively address security concerns and improve their defenses against malicious actors.

I think that one of the most effective forms of cyber security fortification is ongoing training about social engineering and new methods of attack. Exploiting human flaws is an incredibly effective step to bypassing standard security measures.

A few years ago, someone explored ways of gaining physical access to otherwise private areas by simply holding a big ladder and asking for directions inside the building. Even areas that required  badged were vulnerable because some organizations have a lax policy about ‘piggy backing’.

We rely on technology to help us implement security measures, but we always need to remember that security starts with the human who has the privileged access. 

Supply chain attacks are basically “high-risk, high-reward” attacks. These attacks are not easy to orchestrate, but once successful, they can go undetected for weeks/months and deal a lot of damage to the organization.
