debug is a malicious package.
This package version contains malicious code that listens for network traffic when run in the context of a browser and focuses on crypto transactions. The malicious code injected to the packages activates a hook whenever a Web3 wallet is present. Once activated the code intercepts and modifies any transaction with ETH value and points it to another address presumably controlled by the attacker. The malicious code also listens for swap/transfer transactions to tamper with as well.
Note:
This advisory is under ongoing investigation and can be updated with additional details.
Remediation
Avoid using all malicious instances of the debug package.
Affected versions of this package are vulnerable to Open Redirect via the redirect function in lib/response.js due to improper input sanitization. An attacker can redirect users to arbitrary external sites by exploiting this vulnerability.
Remediation
A fix was pushed into the master branch but not yet published.
