blinkit-corenpm
Advisory published Updated
blinkit-core is a confirmed malicious npm package (MAL-2026-6249) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in blinkit-core (npm)
What this malware does
On npm install, the package's preinstall lifecycle hook runs curl against http://d8s0b82plbq3u5sb2vo0sb3a9obr4yjt7.oast.site/ and POSTs the installer's hostname (hostname -f), current user (whoami), working directory, and a base64-encoded dump of the entire process environment (env | base64 -w0) — which on CI/build hosts routinely contains tokens, cloud credentials, and registry auth. The package itself is hollow: index.js only exports { name, version } and provides no functionality. The repository.url claims git+https://github.com/zomato/blinkit-core.git while publishing under that internal-sounding name on the public registry, matching the canonical dependency-confusion attacker shape against Zomato's internal blinkit-core namespace. Installer harm: any build pipeline that resolves this public package instead of an internal mirror leaks host identity and the full environment (including secrets) to the attacker's out-of-band interaction listener at install time, before any other code runs.
The OpenSSF Package Analysis project identified 'blinkit-core' @ 1.0.0 (npm) as malicious.
It is considered malicious because:
-
The package communicates with a domain associated with malicious activity.
-
The package executes one or more commands associated with malicious behavior.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for blinkit-core (version 1.0.0).
If you installed it — respond
blinkit-core 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 blinkit-core 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 blinkit-core-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
