Data Theft Repackaged: A Case Study in Malicious Wrapper Packages on npm
The Socket Research Team breaks down a malicious wrapper package that uses obfuscation to harvest credentials and exfiltrate sensitive data.

Advanced tools
@viamrobotics/prime-core
@viamrobotics/prime-core
is a collection of core Svelte components.
Add PRIME core using your package manager of choice:
pnpm add --save-dev @viamrobotics/prime-core
Install Tailwind. In the tailwind.config.js
, add the components to the content and include the theme:
import { theme } from '@viamrobotics/prime-core/theme';
/** @type {import('tailwindcss').Config} */
export default {
content: [
'./src/**/*.{html,js,svelte,ts}',
'./node_modules/@viamrobotics/prime-core/**/*.{ts,svelte}',
],
theme,
plugins: [],
};
Import the stylesheet. If you are using SvelteKit, you can do this in src/routes/+layout.svelte
.
import '@viamrobotics/prime-core/prime.css';
You can now use the components in your app:
<script lang="ts">
import { Badge } from '@viamrobotics/prime-core';
</script>
<Badge
variant="green"
label="Active"
/>
The playground can be used during development but is not used outside of the package.
pnpm install
pnpm -C packages/core dev
To lint and typecheck:
pnpm -C packages/core check # check svelte and lint
pnpm -C packages/core check-svelte # check svelte only
pnpm -C packages/core check-lint # check lint only with prettier and eslint
pnpm -C packages/core format # format with prettier
To test with vitest:
pnpm -C packages/core test # run once
pnpm -C packages/core test:watch # watch tests
For easier readability, we try to use a standard ordering for component composition. These are not strict rules, but more a guideline to follow. Implementation specifics may force you to go outside this guideline.
