    Write a function that enhances fraud detection by activating all high-risk transaction indicators (represented by even-positioned bits) in a customer's behavioral pattern number, where each bit represents a specific fraud flag. The function should set all even-positioned bits to 1 while preserving the original values of odd-positioned bits in the behavioral pattern, helping identify potential fraudulent activities more effectively.
