#### Executive Summary: The report describes a scam campaign that routes victims through traffic distribution systems to fake CAPTCHA pages which trigger the user’s SMS app with prefilled messages to international/premium numbers; by combining TDS, social engineering, and back-button hijacking the operators induce multiple billable SMS (observed up to ~60 messages) resulting in delayed charges on victims' phone bills.
