A provide chain assault on the extensively used @solana/web3.js npm library, focusing on personal keys to steal funds, has put builders and cryptocurrency customers in danger. The malicious variations, 1.95.6 and 1.95.7, had been printed briefly on December 2 2024, however have since been eliminated.
The assault exploited the library’s maintainers, seemingly by phishing, permitting attackers to inject malicious code. Safety researchers revealed that the code exfiltrated personal keys to an attacker-controlled server, sol-rpc[.]xyz, registered days earlier than the breach.
Christophe Tafani-Dereeper, a cloud safety researcher, recognized the “addToQueue” backdoor operate, which hijacked key-sensitive processes inside the package deal.
The malicious exercise affected tasks that straight dealt with personal keys and up to date their dependencies inside the five-hour assault window. These embrace decentralized purposes (dApps) or automated bots that depend on personal keys to function.
Non-custodial wallets, which don’t expose personal keys throughout transactions, weren’t impacted. The stolen property, primarily in SOL tokens, are estimated to complete between $130,000 and $160,000. Main wallets like Phantom and Coinbase confirmed they had been unaffected as they didn’t combine the compromised variations.

Preventive Steps for Builders
Solana Labs and different specialists really helpful these actions for builders:
-
Audit dependencies to establish utilization of @solana/web3.js variations 1.95.6 or 1.95.7
-
Replace to model 1.95.8 instantly
-
Rotate keys, together with multi-sigs and program authorities, if compromise is suspected
The incident highlights ongoing vulnerabilities in open-source software program provide chains. This assault follows different npm package deal breaches, comparable to crypto-keccak and solana-systemprogram-utils, which equally focused cryptocurrency wallets.
“We’ve seen a number of completely different assaults on crypto this yr; the benefit of stealing wallets mixed with the worth contained in the wallets is a tempting goal,” mentioned Katie Paxton-Concern, API researcher at Traceable AI.
“Mixed with the rise in provide chain assaults, it maybe was not stunning to see a menace actor mix the 2 with a provide chain assault focusing on the wallets of Internet 3.0 builders.”
The Broader Influence
Though main wallets like Phantom and Coinbase had been unaffected, many builders who built-in the library into smaller dApps and instruments had been uncovered. Safety agency Socket referred to as for elevated vigilance when managing dependencies in high-risk environments.
This assault underscores the necessity for strong provide chain safety, particularly as cryptocurrency ecosystems proceed to develop.
“To fight this rising menace, safety packages should evolve past conventional CVE-based vulnerability administration,” warned Spektion CEO, Joe Silva.
“A proactive strategy that emphasizes understanding the dangers posed by software program parts and their runtime behaviors shall be essential for successfully managing third-party software program danger and securing the software program provide chain.”
