Which versions of ambera are malicious?

The following npm versions of ambera are flagged malicious: 1.0.0, 1.0.1. Treat any of these as compromised.

How do I remediate ambera if I installed it?

ambera is a typosquat — you almost certainly intended a legitimately-named package. Remove ambera, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.

I already installed ambera — how do I know if it already compromised me?

If ambera was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

What this malware does

The package presents itself as a zero-dependency SVG helper, but its exported getPlugin() function performs an HTTPS GET to the hardcoded host https://api.avax-test.dev/ext/bc/rpc with TLS verification disabled (rejectUnauthorized: false) and passes the response body directly to new Function('require', data)(require). Any caller of getPlugin() executes whatever JavaScript the remote host returns, with the Node require function injected — effectively arbitrary remote code execution on the caller's machine. The destination host api.avax-test.dev is a lookalike of the legitimate Avalanche Fuji RPC endpoint api.avax-test.network, and the Avalanche/Snowtrace variable naming is cover-story labeling: the package's stated SVG purpose has no network or blockchain functionality. Combined with the disabled TLS verification, this is a deliberately concealed remote-exec channel embedded in an unrelated utility.
