      I hate the phrase "raising the bar", I've noticed people use it when they're pitching some low-quality mitigation that makes the attacker do some busy work but doesn't fundamentally prevent them from achieving their original goal. 😈

      A: "If they have already need an arbitrary read, can't the attacker just read the secret?" B: "Look, this will break existing exploits, we're raising the bar." A: 🤦‍♂️

          I thinks it’s a demonstration that people tend not to fully understand the security problem, and focus entirely on the demonstrated behavior of the current exploit.

          Aren't malware author obfuscating their stuff to waste time on the analyst side ? Sure that protection XYZ is lame but if it takes couple of more days for the attacker to bypass it, isn't it worthwhile ?

          Devils advocate: I bought cheap combination locks for my kids' bikes so when they leave them outside to go play with friends indoors they cannot easily be taken by other kids. They are easy to bypass but "raise the bar" sufficiently to stop the attacks I want to protect against.

          i think talking about breaking current exploits is even worse than talking about “raising the bar.”

          Raising the bar is up there with out of the box. Hate them both!

          It's the positive way of saying "not a security boundary"
