Which versions of async-http-tools are malicious?

The following PyPI versions of async-http-tools are flagged malicious: 0.70.125. Treat any of these as compromised.

How do I remediate async-http-tools if I installed it?

async-http-tools 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.

I already installed async-http-tools — how do I know if it already compromised me?

If async-http-tools 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.

Is async-http-tools part of a known attack campaign?

Yes — async-http-tools is associated with the 2025-06-alembic-util campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find async-http-tools across my projects, lockfiles, and CI pipelines?

Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for async-http-tools (version 0.70.125). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging async-http-tools across your stack and pipelines.

MAL-2026-3702

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

pip uninstall async-http-tools

What this malware does

During installation, package exfiltrates some basic info to a GitHub issue comment, and then attempt to set up a persistent infostealer focused on exfiltrating crypto wallets and browsers data. Likely continuation of 2026-05-py-requests

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2025-06-alembic-util

Reasons (based on the campaign):

infostealer
The package overrides the install command in setup.py to execute malicious code during installation.
crypto-related
Downloads and executes a remote malicious script.
exfiltration-browser-data
exfiltration-crypto
persistence
typosquatting

Credential / info stealer

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for async-http-tools (version 0.70.125). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging async-http-tools across your stack and pipelines.
If you installed it — respond
async-http-tools 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 async-http-tools 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 async-http-tools 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.

Frequently asked questions

Detect & block this

O3 blocks async-http-tools-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
