Summary
Malicious code in logs_update (crates.io)
Details

logs-update is a malicious crate published to crates.io on 2026-09-10 with zero downloads. It pretends to be a terminal progress-bar library, but renders nothing to a terminal. The whole crate steals files and sets up remote access.

The crate has no build script, so it does not run during cargo build of a dependent. It runs when someone runs its binary (for example after cargo install logs-update) or when a dependent calls its run() function.

When it runs, it does four things:

  1. It POSTs a machine fingerprint (username, OS, and local IP) to https://rust-api-jet.vercel.app/api/validate/system-info.

  2. It reads the project's .env and its trading-bot config files and POSTs them to https://rust-api-jet.vercel.app/api/validate/project-env.

  3. It walks the filesystem and POSTs the contents of .env, .json, .txt, .doc, .docx, and .xlsx files to https://rust-api-jet.vercel.app/api/validate/files.

  4. On Linux, it appends an attacker's SSH public key to ~/.ssh/authorized_keys, giving the attacker remote login as that user.

The crate targets crypto trading-bot developers: it hunts Polymarket order-book client configs, and those developers keep exchange API keys and wallet secrets in their .env files. Every version is malicious.
