Many GitHub users this week received a novel phishing email warning of critical security holes in their code. Those who clicked the link for details were asked to distinguish themselves from bots by pressing a combination of keyboard keys that causes Microsoft Windows to download password-stealing malware. While it’s unlikely that many programmers fell for this scam, it’s notable because less targeted versions of it are likely to be far more successful against the average Windows user.

A reader named Chris shared an email he received this week that spoofed GitHub’s security team and warned: “Hey there! We have detected a security vulnerability in your repository. Please contact us at https://github-scanner[.]com to get more information on how to fix this issue.”

Visiting that link generates a web page that asks the visitor to “Verify You Are Human” by solving an unusual CAPTCHA.

Clicking the “I’m not a robot” button generates a pop-up message asking the user to take three sequential steps to prove their humanity. Step 1 involves simultaneously pressing the keyboard key with the Windows icon and the letter “R,” which opens a Windows “Run” prompt that will execute any specified program that is already installed on the system.

Step 2 asks the user to press the “Control” key and the letter “V” at the same time, which pastes malicious code from the site’s virtual clipboard.

Step 3 — pressing the “Enter” key — causes Windows to launch a PowerShell command, and then fetch and execute a malicious file from github-scanner[.]com called “l6e.exe.”

PowerShell is a powerful, cross-platform automation tool built into Windows that is designed to make it simpler for administrators to automate tasks on a PC or across multiple computers on the same network.

According to an analysis at the malware scanning service Virustotal.com, the malicious file downloaded by the pasted text is called Lumma Stealer, and it’s designed to snarf any credentials stored on the victim’s PC.

This phishing campaign may not have fooled many programmers, who no doubt natively understand that pressing the Windows and “R” keys will open up a “Run” prompt, or that Ctrl-V will dump the contents of the clipboard.

But I bet the same approach would work just fine to trick some of my less tech-savvy friends and relatives into running malware on their PCs. I’d also bet none of these people have ever heard of PowerShell, let alone had occasion to intentionally launch a PowerShell terminal.

Given those realities, it would be nice if there were a simple way to disable or at least heavily restrict PowerShell for normal end users for whom it could become more of a liability.

However, Microsoft strongly advises against nixing PowerShell because some core system processes and tasks may not function properly without it. What’s more, doing so requires tinkering with sensitive settings in the Windows registry, which can be a dicey undertaking even for the learned.

Still, it wouldn’t hurt to share this article with the Windows users in your life who fit the less-savvy profile. Because this particular scam has a great deal of room for growth and creativity.
