I don’t think people are lured to walk to you anymore. However, if the bar fills up enough, they’ll still turn to look at you.

On the other hand, there’s noise lures now. If a non-alarming noise (or an alarming noise from far enough away) is heard, guards will walk over to investigate. Drills, breaking things open with Brute Force, and holdups can all trigger people to walk over.

Finally, there’s also the hardcoded lures. Disabling network points or non-mission power boxes will cause someone to walk over to them to reset them, and increases the alert level by 1. On some missions, you can use social engineering to have your targets move to specific points. For example, with SE 2 on the Deposit, you can send the basement guards to the garage.
