In a startling revelation, security researchers from Phylum have identified an ongoing campaign unleashing hundreds of malicious packages on the popular open-source Node Package Manager (NPM). This alarming tactic aims to infect the devices of unsuspecting developers who rely on NPM's extensive library of code resources.

The malicious packages cleverly use names that resemble legitimate libraries—including those for Puppeteer and Bignum.js, as well as various cryptocurrency-related libraries. This insidious campaign follows closely on the heels of a previous wave of attacks targeting developers using modified versions of the Ethers.js library.

Understanding the Threat: Supply Chain Attacks

Phylum researchers caution that this event exemplifies the ongoing threat of supply chain attacks in the software development ecosystem. “Malware authors are constantly innovating ways to disguise their intent,” they stress. The methodologies employed by these attackers pose a significant risk to developers and organizations alike.

When executed, these malicious packages employ a sophisticated means of obscuring the IP addresses used for malicious payloads. Intriguingly, the essential IP address is not directly embedded in the initial code. Instead, it is fetched from an Ethereum smart contract, sparking a new level of complexity in tracking these threats.

The IP addresses that this attack has utilized trace back over time, with each address recorded on the Ethereum blockchain as a permanent, immutable history. Notably, one of the addresses was identified as: http://193.233.201[.]21:3001.

Historical Tracking: A Double-Edged Sword

While attempting to obscure their activities, these attackers inadvertently leave a digital breadcrumb trail. The researchers mapped out the evolution of IP addresses used in this operation, illustrating how each iteration may lead to past attack vectors:

- 2024-09-23: http://localhost:3001

- 2024-09-24: http://45.125.67[.]172:1228

- 2024-10-21: http://45.125.67[.]172:1337

- 2024-10-22: http://193.233[.]201.21:3001

- 2024-10-26: http://194.53.54[.]188:3001

What Happens After Installation?

Upon installation, these nefarious packages—disguised as Vercel packages—initiate a silent operation. They embed themselves in your system to execute on reboot and connect to the predetermined IP source to retrieve harmful JavaScript files. Subsequently, vital system data is transmitted back to the original server, including GPU and CPU details, memory capacity, username, and OS version.

The Typosquatting Trap

One of the key tactics facilitating these attacks is called typosquatting. This approach leverages the slight misspellings or variations in package names to trick developers into downloading harmful code. As this technique has grown in popularity over the past five years, developers must be especially vigilant when selecting which packages to use.

Stay Safe!

Developers are advised to double-check the names and sources of libraries before any installation. The Phylum report details specific names, IP addresses, and cryptographic hashes associated with these rogue packages, equipping developers with the knowledge needed to navigate this minefield of digital threats.
