Malicious RubyGems and PyPI Packages Are Stealing Credentials and Crypto: What Happened and How to Protect Yourself

If you’ve ever installed a “quick automation” gem or Python package to speed up social media posting or crypto staking, this one’s for you. Security researchers just uncovered dozens of malicious RubyGems targeting marketers and growth hackers, quietly exfiltrating usernames and passwords. At the same time, typosquatted packages on PyPI went after Bittensor wallets by hijacking staking functions. The fallout? New rule changes at PyPI to block a sneaky “ZIP confusion” technique that could smuggle malicious files past reviews.

Here’s what that means, why it matters, and what you should do right now to stay safe.

TL;DR: The Fast Facts

A threat actor using the aliases “zon,” “nowon,” “kwonsoonje,” and “soonje” has published 60 malicious RubyGems since at least March 2023. Cumulative downloads exceed 275,000. Not all downloads equal compromises.
These gems promised social media automation (Instagram, X/Twitter, TikTok, WordPress, Telegram, Kakao, Naver) but secretly stole credentials via a simple GUI and exfiltrated data to attacker-controlled servers.
The campaign appears to target Windows users, particularly in South Korea, based on Korean-language interfaces and .kr exfiltration domains.
On PyPI, multiple typosquatting packages mimicking “bittensor” and “bittensor-cli” tried to drain funds by hijacking staking routines.
In response to a broader class of supply chain risks, PyPI will begin rejecting “wheels” (Python package files) that attempt to exploit ZIP parser differences. Enforcement starts February 1, 2026, after a six-month warning period.
If you installed automation gems or Bittensor-related packages recently, audit your environment, rotate credentials/keys, and scan for indicators of compromise.

The RubyGems Campaign: Automation Tools With a Hidden Agenda

What the malicious gems promised—and what they stole

On the surface, the malicious RubyGems looked helpful. They pitched themselves as automation tools for popular platforms:

Instagram and TikTok bulk actions
Twitter/X engagement tools
WordPress posting helpers
Messaging automation for Telegram, Kakao, and Naver

But alongside the “promised” features, the packages also included covert functionality. When the tool launched, it presented a basic graphical user interface asking users for logins. Those credentials were then exfiltrated to attacker-controlled servers.

It’s a classic bait-and-switch: give users enough utility to look legitimate while quietly siphoning off the data that matters most.

Who’s behind it?

According to Socket’s research, the threat actor used multiple aliases across the campaign, including:

zon
nowon
kwonsoonje
soonje

The campaign has been active since at least March 2023. The collective gems racked up more than 275,000 downloads. That number sounds huge, but here’s an important nuance: not every download equals execution or compromise. It’s common for researchers, CI systems, or a single user to create multiple download events.

Even so, the scale signals persistence and reach. And the execution details suggest a focused operation rather than random drive-by uploads.

Indicators and infrastructure

Captured credentials were sent to domains that also advertised bulk messaging and scraping tools:

programzon[.]com
appspace[.]kr
marketingduo[.]co[.]kr

Why that matters: the infrastructure and product positioning align with grey-hat marketing and “growth” tooling. That’s a deliberate choice; the actor wanted to blend in and target a community that might be more willing to enter credentials into third-party tools.

Windows-first, South Korea-leaning—but not confined

Many gems functioned as Windows-targeting infostealers.
Several interfaces used Korean language and exfiltrated to .kr domains.
While South Korean users appear highly targeted, malware rarely respects borders. Anyone using automation gems from unknown authors is at risk.

Notable packages and a disturbing twist: financial forum manipulation

Some of the packages—including names like “njongto_duo” and “jongmogtolon”—reportedly focused on financial discussion platforms. They were marketed as tools to:

Flood investment forums with ticker mentions
Push stock narratives
Drive synthetic engagement to amplify visibility

Beyond credential theft, that hints at market manipulation tactics: astroturfing discourse to influence perception around investments. It’s a reminder that software supply chain abuse isn’t just about malware—it can be about distorting public conversation at scale.

PyPI Typosquatting Packages Targeting Bittensor Wallets

The packages that weren’t what they seemed

GitLab’s Vulnerability Research team flagged multiple PyPI packages that closely mimicked legitimate Bittensor packages. The intent: steal cryptocurrency by hijacking staking functions. Names included:

bitensor (versions 9.9.4 and 9.9.5)
bittenso-cli
qbittensor
bittenso

Why it worked: typosquatting thrives on quick installs and muscle memory. A single missing letter is easy to miss, especially when you’re following a how-to guide or copying commands from a forum.

Why staking was the target

Staking operations are routine and trusted, which makes them ideal for attackers to hide in:

Users expect wallet access and chain interactions during staking.
Slight deviations from normal behavior can be hard to spot.
The impact is immediate: once funds move, recovery is unlikely.

If you used Bittensor-related packages recently, verify you installed the correct libraries, check transaction histories, and rotate keys if you suspect compromise. For background on the project, see the Bittensor documentation.

PyPI’s New “ZIP Confusion” Safeguards: What’s Changing and Why

First, what’s a “wheel”?

A wheel is a built artifact for Python packages—basically a ZIP archive with metadata. Wheels speed up installs and standardize distribution. They’re the format you see as .whl files.

The problem: parser differences can be exploited

A subtle class of attacks emerges when different tools unpack ZIPs differently. If a wheel’s ZIP contents don’t align with its metadata (like the RECORD file), an attacker could try to sneak in files that installers handle inconsistently. That’s the essence of “ZIP confusion.”

Some Python-based installers rely on the standard library’s zipfile behavior.
The popular installer “uv” (a fast, modern Python package manager) has different extraction behavior than many Python-based installers.
Attackers can try to wedge malicious payloads into the ambiguity.

To get ahead of this, PyPI is tightening enforcement:

PyPI will reject wheels attempting to exploit ZIP confusion.
It will also warn publishers when wheel contents don’t match the included RECORD metadata.
After a six-month warning period, on February 1, 2026, PyPI will start rejecting new wheels with mismatched contents.

Credit for disclosure goes to researchers at Google’s Open Source Security Team and Netflix. For ongoing updates, check the PyPI blog and Python packaging discussions on discuss.python.org. For “uv,” see the project page at Astral’s GitHub.

Here’s why that matters: increasingly, software supply chain attacks exploit seams between tools—package formats, installers, and build systems. Aligning behavior and adding pre-upload checks reduces the attack surface before malicious packages spread.

Who’s Most at Risk Right Now?

Marketers and growth hackers using “unofficial” automation gems for social or forum engagement.
Developers on Windows who install RubyGems from unknown publishers.
Python users working with Bittensor wallets or staking operations.
Teams that allow direct internet installs in CI without quarantining or scanning new dependencies.
Anyone who frequently tries “helpful” packages found via search results or forums rather than vetted sources.

If that describes you or your team, it’s time to take a closer look at what you’ve installed and where your credentials live.

What To Do Now: Practical Steps for Developers, Teams, and Solo Users

1) If you installed automation gems or suspicious RubyGems

Review your installed gems for unfamiliar names or those from the listed aliases.
Look for gems tied to social media, messaging, or “bulk engagement” features.
If you find a match, remove the gem, and assume the credentials you entered are compromised.

Immediate actions: – Rotate passwords for any accounts used in those tools. – Revoke tokens and API keys generated for social platforms. – Enable 2FA or passkeys on all affected accounts. – Check account access logs for suspicious activity (new devices, unusual IPs, bulk actions).

Check network indicators (defanged): – programzon[.]com – appspace[.]kr – marketingduo[.]co[.]kr

If your endpoint security or proxy shows connections to these domains, escalate to incident response. Block them at your firewall and DNS layers.

Tools to help: – bundler-audit: checks dependencies against known vulnerabilities. See bundler-audit. – RubyGems security guidance: RubyGems Security.

2) If you installed Bittensor-related Python packages

Confirm the exact package name and version you installed. Typos matter.
Compare against official docs: Bittensor docs.
If you suspect a typosquatted package:
Move remaining funds to a new wallet with fresh keys.
Treat existing keys and staking endpoints as compromised.
Reinstall your Python environment from scratch.
Audit command history and shell scripts for saved commands or keys.

3) Audit your Python and Ruby environments

List installed packages and scan for anomalies:
Python: use pip-audit and Safety to flag known issues.
- pip-audit: GitHub
- Safety: PyPI
Ruby: use bundler-audit and review Gemfile/Gemfile.lock entries.
Rebuild from lockfiles or clean manifests:
Python: pin exact versions and hashes. Use requirements with hashes or lockfiles generated by trusted tools.
Ruby: ensure Gemfile.lock reflects known-good versions.
Verify maintainers and repositories:
Check if the package links to a real GitHub repo with a history and contributors.
Review recent changes and maintainership handoffs.
Look for unexplained binary blobs or obfuscated code.

4) Harden your install and build pipeline

Use virtual environments and containers so installs don’t pollute your base system.
Turn on hash-checking for package installs where possible. For Python, use pip’s hash-checking mode or tools like pip-tools to compile locked dependency sets.
Add a private proxy or repository manager (e.g., JFrog Artifactory, Sonatype Nexus, or Gemfury) to:
Quarantine new packages.
Scan with SCA tools.
Cache known-good artifacts.
Enforce 2FA on all developer accounts across package registries and Git hosting.
Limit egress from CI/CD runners. Block outbound calls to unknown endpoints during builds.
Adopt signed provenance and build integrity frameworks:
SLSA: slsa.dev
Sigstore: sigstore.dev
NIST SSDF: NIST SSDF

5) Incident response if you detect compromise

Rotate all credentials entered into the suspect tools.
Invalidate API keys, OAuth tokens, and session cookies.
Check saved browser passwords and password managers in case of reuse.
Review logs for anomalous activity, including mass posting, DM campaigns, or unusual financial transfers.
Notify stakeholders and, if appropriate, platform security teams.
Consider filing reports with the ecosystem maintainers (RubyGems or PyPI) and your national CERT.

How To Spot Malicious Packages Before You Install

Here’s a quick gut-check list you can run in under five minutes:

The name is a near-match to a popular project (one letter off, swapped characters, strange prefixes).
The package is very new, with a sudden burst of versions and little documentation.
Over-the-top promises: “Unlimited engagement,” “Instant SEO,” “Guaranteed growth.”
The tool asks for credentials via a pop-up UI—even though it’s supposed to be a library.
Embedded binaries or obfuscated code with no clear reason.
Post-install scripts that reach out to unknown domains or download extra payloads.
Maintainer has minimal history, unclear identity, or a recently created account.
Repo links are broken, or the GitHub project has no issues, tests, or contributors.

If you see two or more of these red flags, slow down. Search for the project’s official website, GitHub organization, or documentation. If in doubt, ask in a trusted developer forum or security community before you install.

For Ecosystem Maintainers and Tool Authors: Keep Closing the Gaps

A few ecosystem-level changes make attacks like these harder:

Enforce 2FA for publishers of popular or sensitive packages. PyPI has moved in this direction for critical projects; similar norms in other ecosystems help. See the PyPI blog for policy updates.
Invest in automated detection for typosquatting, credential prompts, post-install network beacons, and obfuscation patterns.
Provide warnings in installers when a package name resembles a popular one.
Encourage and document best practices for hash pinning, lockfiles, and reproducible builds.
Adopt artifact signing and supply chain provenance, and make verification easy by default.

Progress is happening—PyPI’s ZIP confusion guardrails are a good example. But attackers evolve, so consistent policy, layered defenses, and community reporting are essential.

Why This Is Happening More Often

Software supply chains are the new perimeter. Developers trust community ecosystems to move fast, and attackers know it:

Low-cost, high-reach: Uploading a malicious package is cheap and can reach thousands quickly.
Trust exploitation: Users expect build tools, staking scripts, or automation helpers to “just work.”
Psychological leverage: Typosquatting and “too-good-to-be-true” features exploit speed and convenience.

Industry reports continue to show growth in supply chain threats year over year. For broader context, see Sonatype’s annual State of the Software Supply Chain report.

The answer isn’t to stop using open source. It’s to raise the bar on verification, adopt safer defaults, and shape habits that reduce risk.

Frequently Asked Questions

Q: I installed a social media automation gem and logged in through its UI. Am I compromised? – If the gem matches the campaign profile, assume credentials are compromised. Immediately change passwords, revoke tokens, and enable 2FA. Check for network connections to the listed domains and unusual account activity.

Q: Does the 275,000 download count mean there are 275,000 victims? – No. Download counts often include multiple installs by the same user, CI/CD fetches, or researcher testing. Still, the number indicates broad exposure and a persistent operation.

Q: I’m outside South Korea. Should I still worry? – Yes. While UI language and infrastructure suggest a focus on South Korea, supply chain malware often spreads globally. If the tooling sounds relevant to you, take precautions regardless of region.

Q: How do I avoid typosquatted packages on PyPI? – Copy package names from official docs or repos, not blog posts or random tutorials. Double-check spelling and author. If a name looks off (e.g., “bittenso” vs. “bittensor”), don’t install it.

Q: What is “ZIP confusion” and do I need to change my workflow? – It’s when different installers extract wheel files differently, which attackers can manipulate. PyPI’s new checks aim to prevent mismatches. As a publisher, ensure your wheels’ contents match RECORD metadata. As a user, keep your installers updated and prefer mainstream tooling.

Q: Will PyPI’s new policy block legitimate packages? – There’s a six-month warning period before enforcement begins on February 1, 2026. Most legitimate packages won’t be affected if metadata matches contents. The change primarily targets mismatches that could hide malicious payloads.

Q: What should I do if I think a package is malicious? – Report it to the registry (RubyGems or PyPI). Share indicators (names, versions, URLs) with your security team and trusted communities. Avoid posting PoCs or exploit steps publicly—focus on defensive reporting.

Q: Can package signing or Sigstore stop this? – Signing helps verify the package’s origin and tamper status. It’s not a silver bullet against malicious-but-signed packages, but it raises the bar. Combine signing with audit tools, hash pinning, and reputation checks. Learn more at sigstore.dev.

Q: What’s the safest way to test new packages? – Use a disposable container or VM. Block outbound network by default. Inspect code for post-install scripts and network calls. Only promote the package into your main environment after it passes checks.

Q: Are there tools to automate dependency risk reduction? – Yes. Consider pip-audit, Safety, bundler-audit, OWASP Dependency-Check, SCA platforms, and private proxies with quarantine. See pip-audit, Safety, and OWASP Dependency-Check.

The Bottom Line

Attackers are going where the trust is: community package managers and everyday workflows. The malicious RubyGems campaign and the Bittensor-focused PyPI typosquats show how easy it is to hide in plain sight—especially when users are in a hurry or tempted by “growth hacks.”

Action steps to keep you safe: – Audit recent installs, especially automation or staking-related packages. – Rotate credentials or keys if you entered them into third-party tools. – Add package scanning, lockfiles, and hash pinning to your workflow. – Use private proxies, sandbox installs, and 2FA across critical accounts. – Keep an eye on ecosystem updates from PyPI and research by teams like Socket and GitLab.
