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.

TyposquatFind it
Search your lockfiles and build artifacts for @gocortexio/npmgremlinbox-typosquat-lodash (all published versions).
If you installed it — respond
@gocortexio/npmgremlinbox-typosquat-lodash is a typosquat — you almost certainly intended a legitimately-named package. Remove @gocortexio/npmgremlinbox-typosquat-lodash, 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-lodash was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
