Researchers found a malware marketing campaign concentrating on the npm ecosystem, distributing the Skuld data stealer via malicious packages disguised as reputable instruments. The menace actor, “k303903,” compromised a whole lot of machines earlier than the packages have been eliminated.
Subsequent evaluation revealed that “k303903” possible operates beneath the aliases “shegotit2” and “pressurized,” all exhibiting equivalent or extremely related techniques, strategies, and procedures (TTPs) to infiltrate the npm ecosystem with malware by demonstrating the persistent menace of provide chain assaults and the necessity for heightened safety measures throughout the growth ecosystem.
A malicious marketing campaign concentrating on npm builders delivered the Skuld infostealer, marking the second such assault in two months, which intently resembles a earlier assault on Roblox builders, demonstrating the attackers’ adaptability.

The December 2024 marketing campaign leveraged frequent deployment strategies and relied on commodity malware, highlighting the constant use of misleading techniques by these menace actors.
The code snippet reveals a malicious obtain and execution course of by using libraries like `fs-extra`, `path`, `node-fetch`, and `child_process` to obtain a malicious binary from a URL disguised to look reputable after which execute it.
Obfuscator.io was used to obfuscate the code, making preliminary detection difficult. As soon as put in, the malware fetches and executes the payload (Skuld infostealer) beneath the filename obtain.exe.
Actor k303903 used typosquatting to add malicious npm packages that resembled in style libraries, which deceived builders into putting in them, enabling knowledge exfiltration through a Discord webhook and command and management institution.
Leveraging legitimate-looking instructions and a trusted service (replit.dev) additional obfuscated the malicious intent, which highlights the significance of cautious package deal evaluation earlier than set up.
Malicious npm packages have been lately downloaded over 600 instances, stealing credentials and delicate knowledge from affected customers. Regardless of the npm registry’s swift removing, the affect was substantial.
In line with Socket, the assault, resembling a November 2024 incident, demonstrates the fast evolution of menace actors who reuse malware (like Skuld) and refine their deception strategies.
To mitigate this, builders ought to implement a layered safety strategy. Using automated instruments can proactively scan for and block malicious dependencies throughout the growth lifecycle, intercepting threats earlier than they compromise methods.
