gloggonpm
Advisory published Updated
gloggo is a confirmed malicious npm package (MAL-2026-16054) that typosquats a legitimate package to trick installs (malicious versions 1.1.2, 1.1.3, 1.1.4). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in gloggo (npm)
What this malware does
gloggo impersonates the legitimate gulpjs 'glogg' logging library by copying its README, shields, and LICENSE text (attributed to Blaine Bublitz), while package.json attributes authorship to 'Blockvora Team [email protected]' with repository 'blockvora/gloggo'. The package name is a one-character variant of 'glogg'. getLogger() invokes isSign('favorite','gloggo',12467) from the dependency 'file-type-detector' and, when that gate returns truthy, executes require('./log'). The './log' module is not present in the tarball, so its bytes must be produced or supplied at require time by the dependency. A logging utility has no legitimate reason to gate its loader on an opaque file-signature check from an unrelated third-party dependency, and the gated path executes code that is not part of the shipped package contents. Consumers who install gloggo believing it to be glogg import a typosquat that conditionally runs code sourced from a suspicious sibling dependency when the module is required.

TyposquatFind it
Search your lockfiles and build artifacts for gloggo (3 malicious versions).
If you installed it — respond
gloggo is a typosquat — you almost certainly intended a legitimately-named package. Remove gloggo, 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 gloggo 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.

Detect & block this
O3 blocks gloggo-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
