Top most unethical hack is the ability to manipulate behavior of people using mind control methods.
I have written answers about other non psychological hacks earlier.
Our mind is more predictable than we can ever think of.
- Marketers are using these hacks since eon.
- Seducer,charmers,film stars,politicians are master in them. These hacks give so much power to a person that it’s like one is fighting with swords and other from bare hands.
Working of mind is a field in which everyone must have basic idea. I can’t divulge any methods here since most of them are inappropriate and unethical but like a ethical hacker you must know them, just to protect yourself from psychopaths and sociopaths.
