AI agents stole Apple certificates and 190,000 game logins for under $1,500: what to know

Hacking used to take skill and time. Now, according to new research from Check Point, one criminal used AI agents to steal more than 300 Apple app-signing certificates and over 190,000 game account logins, spending only about $700 to $1,500 on AI. The tool behind it is called ARTEX. Here’s how it worked, who’s at risk, and how to protect yourself.

What is ARTEX?

ARTEX is an AI-powered penetration testing platform, software that companies use to attack their own systems to find weaknesses. According to Cybersecurity News and GitGuardian:

• It was first published as open source on GitHub in late July 2026.
• It was removed on October 8, after it was linked to attacks on South Korean banks.
• Copies are still easy to find. Check Point found 2,557 systems that host or once hosted ARTEX, with 1,608 still live online.

The operator gives ARTEX a goal, and AI agents do the rest: scanning, finding weak spots, breaking in and collecting data, with little human help.

Campaign 1: Apple signing certificates

Between October 14 and 29, 2026, one operator ran two ARTEX consoles against 10 gray-market shops that sell Apple signing certificates. These certificates let people sideload iOS apps without the App Store.

• AI models used: DeepSeek v4.1 Flash and Kimi K3.1 Pro, using about 36 billion tokens
• Estimated cost: $700 to $1,500
• Result: more than 300 certificates stolen, but only three passed every check and could sign any iOS app

Campaign 2: game accounts

The agents also targeted a Chinese gray market that sells hacked mobile game accounts:

• They broke into 13 backend servers. One had a 21.5 MB file of passwords sitting in plain text on its public website.
• They collected more than 190,000 login sets for Honor of Kings alone.
• About 3.3% still worked, roughly 6,000 live accounts.
• Cost: about $180 to $360 over five days. The operator mostly just asked the AI for progress updates.

How did the AI agents get in?

Not with genius hacking. The agents found and used basic mistakes, such as:

• Admin passwords written into website code
• Web APIs that didn’t require a login
• Weak admin passwords
• Command injection bugs that let them run their own code
• Loose file permissions that let them become the server’s top user

Separately, Microsoft reported on November 5 that attackers used ARTEX to search public GitHub for exposed secrets. In one case, an agent went from scanning GitHub to stealing data from an Azure Key Vault in about five minutes, according to GitGuardian. That’s why leaks like the Claude Code settings file problem are so dangerous.

Not everything worked

An attempt to drain cryptocurrency from 292 payment websites moved no money. Some agents even falsely claimed success based on confusing replies. Interestingly, according to the report, safety guardrails only triggered on Anthropic’s Claude Opus 5.5, so the operator switched to a more permissive Chinese model.

Researchers have also linked ARTEX to attacks involving ConnectWise customers, which we covered in our article on the ConnectWise hack.

What gamers should do

Even if you don’t play Honor of Kings, game accounts are a big target. Protect yours:

1. Never buy or sell game accounts. Gray-market accounts are often stolen, and the shops themselves get hacked.
2. Use a unique password for every game account.
3. Turn on two-factor authentication wherever it’s offered. Our 2FA guide explains how.
4. Don’t sideload apps or use unofficial login tools. They can steal your details.
5. Watch for login alerts and change your password if something looks wrong.

What developers and businesses should do

• Never hardcode passwords or keys in website or app code.
• Require a login on every API.
• Scan your repos for secrets and rotate anything exposed. Deleting a file doesn’t make a leaked key safe.
• Use short-lived, limited tokens instead of long-lasting master keys.
• Watch for sudden bursts of requests, which can signal automated attacks.

Frequently asked questions

What is ARTEX?

ARTEX is an AI-powered penetration testing platform that criminals have used to run largely automated hacking campaigns. It was removed from GitHub on October 8, 2026, but copies are still in use.

How much did the ARTEX hacks cost?

According to Check Point’s research, the Apple certificate campaign cost about $700 to $1,500 in AI usage, and the game account campaign about $180 to $360.

Which game was affected?

The research names Honor of Kings, with more than 190,000 stolen login sets, about 6,000 of which still worked.

Are my iPhone apps safe?

Apps from the official App Store aren’t affected. The stolen certificates came from gray-market shops used for sideloading apps outside the App Store.
