In phishing scams, hackers pose as trusted figures to trick people into handing over passwords.
The FBI says phishers are proliferating.
In fact, they stole over $57 million from more than 114,000 victims in the US last year.
And according to Business Insider, their techniques are getting increasingly sophisticated.
Hackers will start by targeting low-level employees, then "moving laterally" to compromise executives' accounts.
