I’ve often used “target=_blank” in my posts so that people can click on a link without leaving the original page. So do many people. This turns out to be a seriously risky practice, though. When you open a window with an anchor tag specifying “target=_blank”, you give the target window control of the original window’s
location object! This means that the target window can modify the content of the original window, possibly redirecting it to a phishing page.
