instalogin1234PyPI
instalogin1234 is a confirmed malicious PyPI package (MAL-2026-11503) that steals credentials and exfiltrates sensitive data (malicious version 0.0.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in instalogin1234 (PyPI)
What this malware does
The package presents itself as a 'Modern Instagram CLI' but its login command displays a fake Instagram login prompt that reads a username and password via input() and POSTs the concatenated credentials to a hardcoded Discord channel (channel id 1246456414843437101) using a hardcoded Discord bot authorization token embedded in shell.py. After exfiltration it opens https://instagram.com/ in the user's browser as cover so the interaction appears to succeed. The advertised purpose is a cover story for credential harvesting; the Discord channel and bot token are attacker-controlled.
The package promises to be an Instagram CLI and offers "login". Entered credentials are sent to a Discord channel, and the user is presented with the Instagram website just opened in the browser.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for instalogin1234 (version 0.0.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging instalogin1234 across your stack and pipelines.
If you installed it — respond
instalogin1234 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 instalogin1234 was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks instalogin1234 before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Detect & block this
O3 blocks instalogin1234-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
