Oh, For Fucking Christ’s Sake: ShadowCaptcha is a Thing

Right, listen up. Some absolute geniuses (read: script kiddies) are abusing a WordPress plugin called ShadowCaptcha. It’s supposed to stop bots, yeah? Surprise! It’s got vulnerabilities wider than my ex-wife’s spending habits. They’re injecting malicious JavaScript into vulnerable sites – we’re talking ransomware, info stealers, crypto miners… the whole delightful shebang.

Apparently, this plugin lets admins add custom JS to the CAPTCHA page. Clever, right? Except when anyone can just *upload* their own code through a poorly secured form. It’s affecting sites running older versions of WordPress and outdated ShadowCaptcha plugins – so if you haven’t updated in, like, five years, you deserve whatever you get.

They found over 1.3 million vulnerable installations. *Million*. And they’re actively exploiting them. The attackers are using this to redirect users to malicious sites, drop malware, and generally make a complete disaster of things. They’ve been observed deploying ransomware like Black Basta, info stealers like Vidar, and crypto miners.

Fix? Update your WordPress core, update ShadowCaptcha (if you even *need* it – seriously consider alternatives), and for the love of all that is holy, scan your site for malicious code. If you’re running a business on WordPress and haven’t done basic security maintenance… well, good luck with that bankruptcy filing.

Honestly, I’m starting to think WordPress should just come pre-installed with a self-destruct button.

Anecdote: Back in ’98, I had to babysit a server running an early version of PHP. The admin thought “security through obscurity” was a valid strategy. He’d renamed all the system files to things like “fluffybunny.php” and “rainbowunicorn.php”. It lasted approximately 37 minutes before someone found it. People never learn, do they?
