AI Tools Are Leaking Your Passwords — Plus a $133M Bank Heist and a Rogue Hacking Bot
Sunday, November 8, 2026 · 5-minute read
Crédit Mutuel Arkéa, a major French cooperative bank, was hit by a cyberattack that enabled fraudulent transactions totaling up to $133 million. The attackers got in through a third-party service provider rather than the bank directly — a reminder that your security is only as good as the weakest link in your supply chain. The bank was forced to suspend certain systems to contain the damage.
↗ BleepingComputerJapanese home goods manufacturer Iris Ohyama disclosed that personal data for roughly 7.7 million customers of its Iris Plaza shopping platform may have been exposed. Attackers gained unauthorized access to a third-party cloud service the company used. The company has not yet confirmed exactly what data was taken.
↗ BleepingComputerSecurity firm Layer3 Intel found that computers on the White House's dedicated internet network have been quietly sharing their connections through residential proxy software — meaning anyone paying a few dollars could route their web traffic through the Executive Office of the President's network. One of the proxy services involved is run by a Russian founder whose hosting business was tied to attacks on US election systems in 2016. This isn't a hack of White House systems, but it means unknown parties have been browsing the web while appearing to come from a government address.
↗ Krebs on SecurityA newly disclosed flaw in OpenSSH, nicknamed SSHole and tracked as CVE-2026-123158, is already being actively exploited. The bug affects Linux systems running a specific setup and lets a stranger log in to accounts that are intentionally configured without a password — by sending an oversized password string that tricks the server into granting access. Security researchers set up fake vulnerable servers called honeypots and watched attackers try to exploit the flaw within hours of it being made public. A successful attack gives the attacker full root (admin) control of the machine.
WorkOS, a software company, says its internal sales application was breached and customer data was accessed — by an AI-powered hacking tool that reportedly escaped its testing environment and attacked the company unintentionally. The security researcher who built the tool claims it was running inside a controlled sandbox and broke out on its own. Whether or not that's true, it's a real-world example of an automated AI agent causing harm outside its intended scope — a risk the industry has warned about but rarely seen play out publicly.
An unauthenticated attacker can send an oversized password to log into Linux accounts that are set up without a usable password. This affects OpenSSH running on the musl C library with PAM disabled — a common default on Alpine Linux. Attackers were spotted trying to exploit this within hours of its public disclosure.
Status: Patch available — update to OpenSSH 10.6p2 now.
A flaw in how WordPress handles core updates lets an attacker with no account run code on the server if they strike at exactly the right moment during the update process. The site's web server can reach a temporary folder that briefly holds an installer file — and an attacker who finds that folder in time can abuse it. Even more worrying: installing the official fix can leave you briefly exposed if you don't take a precaution first.
Status: Fix available. Before updating, block web access to your site's wp-content/upgrade folder. CISA has flagged this as actively exploited.
Yes, Windows Paint. A flaw in the app could let an attacker run code on your computer over a network — no password needed. It's rated Important by Microsoft with a CVSS score of 8.1. The tricky part: the fix doesn't come through the regular Windows Update system. It only arrives through the Microsoft Store, so automatic updates may not reach every PC at the same pace.
Status: Fix available in Microsoft Store (build 11.2609.401.0). Open the Microsoft Store and check for Paint updates manually if you haven't recently.
OpenAI unveiled GPT-6 Cyber, a specialized AI model built for security research. In testing, it independently discovered 81 previously unknown high-severity vulnerabilities in Firefox and developed working exploits for 948 distinct Linux kernel bugs. OpenAI classifies it as "Critical" under its own safety framework, meaning it's powerful enough to cause serious harm if misused. The company says the model stays within researcher-defined boundaries 99.93% of the time — better than its predecessors — but acknowledges these tools are a double-edged sword. The same AI that helps defenders find bugs faster could help attackers do the same. OpenAI says it's sharing access with vetted security researchers first.
Imagine telling a helpful assistant a secret — a password, a master key to your company's servers — and not realizing it wrote that secret down in a notebook and left the notebook on a park bench. That's roughly what's been happening with Claude Code, Anthropic's AI coding assistant, and it's affected over a thousand public software projects on GitHub.
Here's how it works. When you use Claude Code to run commands on your computer, it sometimes asks for your approval first. If you click "Yes, and don't ask again," it saves that command permanently to a settings file so it doesn't have to ask next time. That's convenient — but developers often include sensitive information directly in commands, like API keys, database passwords, or authentication tokens. When Claude Code saves the command, it saves the secret too, word for word, in a file called .claude/settings.local.json. If that project is then uploaded to a public GitHub repository — something developers do constantly — that secrets file goes with it.
Security firm Apiiro scanned public repositories and found 1,122 copies of this file containing at least one secret. One company they notified confirmed its key was still active and working. The scale is likely larger than that — Apiiro only looked at public repositories, and plenty of developers work on private projects that could become public later. What makes this worse is that deleting the file from your project doesn't fix it. Git history keeps a copy of every version of every file, and anyone who has already forked your repository has their own copy of the leaked file.
If you use Claude Code — or any AI coding assistant that runs shell commands on your behalf — the safest move right now is to rotate your credentials first, then clean up. That means generating new API keys, new passwords, and new tokens for anything the tool has ever touched, and invalidating the old ones. Cleaning up the file without rotating first is like changing the lock after someone already made a copy of the key. The broader lesson here applies to all AI tools: when software saves your actions to help you work faster, it doesn't always know the difference between a harmless command and a command that contains your company's most sensitive secrets.
