Eric Law discusses security challenges when building applications that display untrusted content, particularly in web browsers. He highlights the "line of death" (LoD), which separates trusted content (above the LoD) from potentially harmful content (below it). If users mistakenly trust content below this line, they can be misled into unsafe actions without realizing it. While browsers like Chrome attempt to indicate this boundary with a chevron, its inconsistent application and subtle design may lead users to fall for fake indicators. Additionally
