Which versions of bootstrap-setflexcolor are malicious?

The following npm versions of bootstrap-setflexcolor are flagged malicious: 1.9.15. Treat any of these as compromised.

How do I remediate bootstrap-setflexcolor if I installed it?

Remove bootstrap-setflexcolor from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed bootstrap-setflexcolor — how do I know if it already compromised me?

If bootstrap-setflexcolor 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 bootstrap-setflexcolor part of a known attack campaign?

Yes — bootstrap-setflexcolor is associated with the RLMA-2025-06073, RLUA-2026-01131 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 bootstrap-setflexcolor 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 bootstrap-setflexcolor (version 1.9.15). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging bootstrap-setflexcolor across your stack and pipelines.

Detection & response playbook

Malicious package

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for bootstrap-setflexcolor (version 1.9.15). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging bootstrap-setflexcolor across your stack and pipelines.
If you installed it — respond
Remove bootstrap-setflexcolor from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If bootstrap-setflexcolor 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 bootstrap-setflexcolor 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.

Frequently asked questions
