anchored·42Tga3…XMGKSummary
In early December 2024, two malicious versions (1.95.6 and 1.95.7) of the widely used @solana/web3.js npm library were published after an account with publish rights was reportedly phished. The injected backdoor sent private keys to an attacker-controlled server; reported losses vary by source, from roughly $130K to over $190K. Affected versions were removed and 1.95.8 was released. This page covers only the incident; see /solana for the related ecosystem page.
