@leviosa86com/leviosa86-testnpm
Advisory published Updated
@leviosa86com/leviosa86-test is a confirmed malicious npm package (MAL-2026-10625) that steals credentials and exfiltrates sensitive data (malicious versions 4.999.0, 5.999.0, 6.0.0…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @leviosa86com/leviosa86-test (npm)
What this malware does
Package @leviosa86com/[email protected] ships src/poc/index.js which shells out via child_process.exec to collect host identifiers (hostname, pwd, whoami) and the installer's public IP (curl https://ifconfig.me), then concatenates the collected data into a subdomain label and triggers a DNS lookup (nslookup) against a unique subdomain of oast.site (a d9bd62bu6g119svvav70o3p9tymtrxkoj.oast.site Interactsh out-of-band interaction server), exfiltrating host recon over DNS to an attacker-controlled OAST endpoint. package.json declares preinstall: node index.js; a root index.js is not present in the tarball, so the default install may no-op, but the shipped src/poc/index.js payload is unambiguous exfiltration recon and the package name/version shape (@leviosa86com/[email protected], a very high version) matches a namespace-squat / dependency-confusion attempt targeting a private @leviosa86com scope.
The OpenSSF Package Analysis project identified '@leviosa86com/leviosa86-test' @ 6.2.1 (npm) as malicious.

Credential / info stealerFind it
Search your lockfiles and build artifacts for @leviosa86com/leviosa86-test (4 malicious versions).
If you installed it — respond
@leviosa86com/leviosa86-test is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If @leviosa86com/leviosa86-test 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 @leviosa86com/leviosa86-test-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
