@gocortexio/npmgremlinbox-typosquat-webpacknpm
Malicious code in @gocortexio/npmgremlinbox-typosquat-webpack (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
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. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
Malicious versions
Every published version of this package is considered malicious — remove it entirely.

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