## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

The package impersonates the legitimate @tailwindcss/typography plugin: README, src/index.js, src/utils.js, and src/styles.js are copied verbatim from the Tailwind Labs plugin, and peerDependencies lists tailwindcss to reinforce the masquerade, but the package is published under the unrelated name typography-stylecss. Appended to src/index.js after the legitimate \`module.exports = plugin.withOptions(...)\` is an obfuscator.io-style payload (hex-named identifiers \_0x168f6b, \_0x3fc27f, etc., with a rotated string table \_0x5975). Decoded string-table fragments include platform branching ('win32', 'windows', 'agent-linux-') and a URL path template \`/agents/\<deploymentHash\>\` built against a base URL read from a \`\_\_SSTAR\_API\_BASE\` global, consistent with downloading a platform-specific agent binary and executing it. Because this code sits at module top level, it fires on \`require('typography-stylecss')\` / \`import 'typography-stylecss'\` — exactly the usage the cloned README instructs developers to add to their \`tailwind.config.js\`. Any build or dev server that loads the Tailwind config will trigger the dropper, which fetches and runs an attacker-controlled native binary on the installer's machine.
