Harry Potter Spell Unlocks Backdoor on Mac Chips

The Mac on your desk or on the cafe table next to you has a chip with secret functions that can be unlocked only by inputting a spell from the Harry Potter series. That fun fact was presented Wednesday at theNoSuchCon security conferenceby veteran reverse engineer Alex Ionescu.

"The attacks discussed in my presentation are attacks that likely only a nation-state adversary would have the sufficient technical knowledge to implement, and they require precise knowledge of the machine that is being targeted," Ionescu, who is chief architect at security firm CrowdStrike, wrote in an e-mail to Ars. "They are perfect, for example, at a border crossing where a rogue country may need to 'take a quick look at your laptop' to 'help prevent terrorism.' I don't suspect most Mac users would be at a high-profile enough level to warrant such level of interest from another state."
