oauth-connectnpm
Advisory published Updated
oauth-connect is a confirmed malicious npm package (MAL-2024-2779) that steals credentials and exfiltrates sensitive data (malicious versions 0.1.1, 2.0.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in oauth-connect (npm)
What this malware does
package.json declares a preinstall: node index.js hook that fires automatically on npm install. index.js collects installer-side data — os.hostname(), os.userInfo(), home directory, DNS server configuration, the contents of /etc/passwd and /etc/hosts, and the contents of the consumer's package.json — then HTTPS POSTs the assembled JSON to f3js0y9srl22itqjffo9jbl8mzswgm4b.oastify.com, an attacker-controlled Burp Collaborator subdomain. The package's advertised purpose (an OAuth helper) bears no relationship to reading /etc/passwd or beaconing host identifiers off-machine. This is a reconnaissance / dependency-confusion exfiltration payload that runs unattended on every installer.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for oauth-connect (2 malicious versions).
If you installed it — respond
oauth-connect 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 oauth-connect 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 oauth-connect-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
