myasicapiPyPI
Advisory published Updated
myasicapi is a confirmed malicious PyPI package (MAL-2026-984) that steals credentials and exfiltrates sensitive data (malicious version 0.2.5). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in myasicapi (PyPI)
What this malware does
The code and related Github project promise to monitor hardware cryptominers. However, the code additionally hides two malicious capabilities functionalities:
- acting as an attacker-controller proxy,
- reversed shell to the attacker-controller endpoint.
They start automatically together with the promissed simple monitoring.
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
Campaign: 2026-02-old-myasicapi
Reasons (based on the campaign):
-
The package contains code to create a reverse shell, allowing an attacker to execute any commands on the victim's machine.
-

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for myasicapi (version 0.2.5).
If you installed it — respond
myasicapi 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 myasicapi 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 myasicapi-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
