dcchbotPyPI
Advisory published Updated
dcchbot is a confirmed malicious PyPI package (MAL-2026-3689) that steals credentials and exfiltrates sensitive data (malicious versions 1.8.1, 1.8.3, 1.9…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in dcchbot (PyPI)
What this malware does
The package performs multiple installer-hostile behaviors. (1) dcchbot/init.py auto-invokes run() on import, which triggers interactive input() prompts and an outbound HTTPS GET to a non-PyPI third-party domain (https://evan0708.rf.gd/pypi-backup/json) — any import (including by IDEs, linters, or dependency scanners) blocks on stdin and beacons to attacker-controlled infrastructure. (2) main.py reads data['info']['version'] from that rf.gd endpoint and later uses the value directly inside os.system(f'pip install dcchbot=={latest_version}') in the /bot-update slash handler; a crafted response (e.g. containing shell metacharacters) yields arbitrary command execution on the installer's host. The rf.gd free-subdomain pattern can also be re-registered by third parties if the account lapses, making this a latent RCE channel. (3) main.py hardcodes CODER_ID = 1317800611441283139 and authorizes that Discord user ID inside /op, /stop, /token, and /bot-update handlers in addition to the installer's OWNER_ID — the package author can, on any Discord server where an installer's bot is present, leak the bot token (/token sends bot._token), grant themselves administrator, or trigger the vulnerable update command. This is direct installer-side harm: token exfiltration, privilege escalation on the installer's Discord servers, and remote shell command execution driven by an external URL.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for dcchbot (5 malicious versions).
If you installed it — respond
dcchbot 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 dcchbot 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 dcchbot-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
