@dransay/loggernpm
Advisory published Updated
@dransay/logger is a confirmed malicious npm package (MAL-2026-17697) that opens a backdoor for remote access (malicious version 99.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @dransay/logger (npm)
What this malware does
@dransay/[email protected] is a dependency-confusion probe claiming the internal @dransay/* namespace, not an identified public package. Its preinstall hook runs on npm install as node beacon.js and sends a DNS lookup and an HTTPS GET to db3klhbi6i9hark1kegg174t38h33b6wt.oast.site, using the package name in the request; npm account 0xamino_hunter published it on 2026-10-08.
The package @dransay/[email protected] ships a preinstall hook (node beacon.js) that fires on npm install. The script performs a DNS lookup and HTTPS GET to the interactsh collaborator host db3klhbi6i9hark1kegg174t38h33b6wt.oast.site, encoding the package name in the subdomain/path. The version number (99.0.0) is implausibly high for a package with no release history, consistent with a dependency-confusion squat intended to win semver resolution against a private internal name. On install, the beacon discloses the installer's source IP, DNS resolver, and timestamp to a third-party host under the scoped name @dransay/logger, confirming successful resolution of this public package in an environment that may have intended to resolve a private @dransay/* package. No further payload is executed in this version, but the install-time callback to an attacker-controlled OAST endpoint is the reconnaissance stage of a dependency-confusion attack.

Detection & response playbook
Backdoor / remote accessFind it
Search your lockfiles and build artifacts for @dransay/logger (version 99.0.0).
If you installed it — respond
@dransay/logger 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 @dransay/logger 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 @dransay/logger-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the C2 callback and severs the channel.
