amberanpm
ambera is a confirmed malicious npm package (MAL-2026-14225) that typosquats a legitimate package to trick installs (malicious versions 1.0.0, 1.0.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in ambera (npm)
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.

Detection & response playbook
TyposquatFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for ambera (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging ambera across your stack and pipelines.
If you installed it — respond
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.
Did it already run?
If ambera was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks ambera before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

O3 blocks ambera-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
