Which versions of tabullates are malicious?

The following PyPI versions of tabullates are flagged malicious: 1.0.1, 1.0.2, 1.0.3, 1.0.4. Treat any of these as compromised.

How do I remediate tabullates if I installed it?

tabullates 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 tabullates — how do I know if it already compromised me?

If tabullates 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 tabullates part of a known attack campaign?

Yes — tabullates is associated with the 2025-11-spellcheckers 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 tabullates 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 tabullates (4 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging tabullates across your stack and pipelines.

Malicious package

Malicious code in tabullates (PyPI) Remove it immediately and rotate any exposed credentials.

MAL-2026-562

Immediate action

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

pip uninstall tabullates

What this malware does

Packages contain hidden code that is effectively run during importing or using the library, and downloads second stage code. Then, a process running in background periodically connects to a remote host and waits for next code to execute

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

Campaign: 2025-11-spellcheckers

Reasons (based on the campaign):

obfuscation
Downloads and executes a remote malicious script.
The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for tabullates (4 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging tabullates across your stack and pipelines.
If you installed it — respond
tabullates 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.

Did it already run?
If tabullates 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 tabullates 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.

Detect & block this

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