Which versions of tailwind-typography-cssstyle are malicious?

Every published version of tailwind-typography-cssstyle on npm is considered malicious. Remove the package entirely.

How do I remediate tailwind-typography-cssstyle if I installed it?

tailwind-typography-cssstyle establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

I already installed tailwind-typography-cssstyle — how do I know if it already compromised me?

If tailwind-typography-cssstyle 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.

Is tailwind-typography-cssstyle part of a known attack campaign?

Yes — tailwind-typography-cssstyle is associated with the GHSA-p4c4-cvj7-95pp campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find tailwind-typography-cssstyle across my projects, lockfiles, and CI pipelines?

Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for tailwind-typography-cssstyle (all published versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging tailwind-typography-cssstyle across your stack and pipelines.

What this malware does

tailwind-typography-cssstyle is a malicious npm package that when imported downloads a C2 dropper (part of PolinRider campaign) from crypto transactions and executes it.

The package tailwind-typography-cssstyle was found to contain malicious code.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer.
