A malicious npm package named pdf-to-office was discovered targeting cryptocurrency wallets. The package, posing as a PDF to Office converter, injects malicious code into locally installed Atomic and Exodus wallets. This attack modifies legitimate files to redirect crypto funds to the attacker's wallet. The campaign shows persistence, as removing the malicious package doesn't remove the injected code from the wallets. Multiple versions of both wallets were targeted, with the attackers adapting their code accordingly. This incident highlights the growing scope of software supply chain risks, particularly in the cryptocurrency industry, and emphasizes the need for improved monitoring of both source code repositories and locally deployed applications.
