Enterprise Security / Phishing Attacks
Cybersecurity experts at Impress IT Solutions are alerting businesses in West Houston to a new phishing scam that uses CAPTCHA tricks to evade security scanners. Threat actors have been found using fake PDF documents hosted on the Webflow content delivery network (CDN) to steal sensitive information, including credit card details.
How These Attacks Are Being Executed
Researchers have identified a widespread phishing campaign where cybercriminals lure victims searching for documents, books, and charts on search engines. When users click on malicious PDF files, they encounter an embedded CAPTCHA image. Once completed, victims are redirected to a phishing page that hosts a legitimate Cloudflare Turnstile CAPTCHA, further adding to the illusion of legitimacy.
Once the real CAPTCHA is completed, users are taken to a fake “download” page where they are prompted to enter personal and financial information. If the victim submits their credit card details, an error message appears, prompting them to re-enter the data multiple times before redirecting them to an HTTP 500 error page.
Methods Used in These Attacks
- Hosting Malicious PDFs on Webflow CDN – Attackers leverage a trusted platform to evade detection.
- Embedding Fake CAPTCHA Challenges – Making the phishing attempt appear more legitimate.
- Redirecting to a Real CAPTCHA Check – Using Cloudflare Turnstile to trick victims further.
- Harvesting Financial Information – Victims unknowingly provide credit card details multiple times.
- Bypassing Security Scanners – CAPTCHA mechanisms prevent traditional phishing detection tools from flagging these sites.
