StepSecurity has detected a new npm supply chain attack campaign using preinstall hooks to download the Bun JavaScript runtime and execute an 11 MB obfuscated payload. At least two SAP-ecosystem packages are confirmed compromised so far.

@bitwarden/[email protected] — the official command-line interface for the Bitwarden password manager — was found compromised on npm.
