Impress IT Solutions, a trusted local IT and cybersecurity provider, is warning businesses and developers in the region to remain on high alert following recent discoveries of malicious npm packages linked to North Korean threat actors. These packages are part of a wider supply chain attack designed to deliver BeaverTail malware and enable remote system access through a stealthy malware loader.
These threats were uncovered as part of the ongoing “Contagious Interview” campaign, where attackers pretend to recruit developers only to infect their systems and siphon data.
“Local developers and small businesses in West Houston who rely on npm packages for their projects are increasingly being targeted by global threat actors,” said a cybersecurity specialist from Impress IT Solutions. “This is a clear example of how sophisticated attacks are now creeping into everyday development tools.”
What Happened?
Cybersecurity researchers recently identified 11 malicious npm packages that were downloaded over 5,600 times before being taken down. The packages disguised themselves as common developer tools but secretly contained code to deliver BeaverTail, a JavaScript-based information stealer, and a secondary remote access trojan (RAT) loader.
The packages included:
- empty-array-validator
- twitterapis
- dev-debugger-vite
- snore-log
- core-pino
- events-utils
- icloud-cod
- cln-logger
- node-clog
- consolidate-log
- consolidate-logger
Why It’s a Threat
These fake libraries use obfuscation techniques, such as hexadecimal encoding, to bypass detection tools and audits. Once installed, they act as malware loaders capable of downloading and executing remote JavaScript, giving attackers full access to compromised systems.
“The loader itself is dangerous even if it doesn’t immediately deliver a payload,” said the team at Impress IT Solutions. “It opens the door for future malware, including data exfiltration tools or ransomware.”
What West Houston Businesses Should Know
The cybercriminals behind this campaign—linked to the infamous Lazarus Group—are specifically targeting developers by posing as hiring companies and sharing malicious code repositories on GitHub and Bitbucket. They’ve even disguised one of the packages in a folder named “eiwork_hire,” tying the infection to job interview scams.
Once inside, the malware (including variants like InvisibleFerret and a Windows-based implant called Tropidoor) can:
- Steal financial and intellectual property
- Run and terminate processes
- Capture screenshots
- Exfiltrate files
- Wipe systems by overwriting data
Tropidoor, which is deployed through BeaverTail, operates in memory, uses legitimate Windows commands, and communicates with a command-and-control server to carry out its functions.
