A large-scale ClickFix campaign compromises hundreds of WordPress websites to deliver a macOS infostealer via fake Cloudflare CAPTCHA overlays. The campaign uses a Polygon blockchain smart contract to store the C2 URL, making it resistant to DNS takedowns. Victims are tricked into pasting a Terminal command that downloads an in-memory payload via curl, which uses osascript to harvest Keychain data, browser credentials, SSH keys, and screenshots before exfiltrating them in chunks to an attacker-controlled server.
