## What is MAL-2026-11503?

MAL-2026-11503 is a malicious package in instalogin1234, published on 3 Aug 2026. 

### Official description

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.
