Summary

Over the past two years, the internet has been inundated with celebrity Deep Fake videos of all kinds: Obama, Putin, and Trump deliver speeches they never gave, Gal Gadot "stars” in a porn video, and professional comedians such as Bill Hader eerily turn into the people they impersonate, like Tom Cruise and Arnold Schwarzenegger.

What all of these videos have in common is that they were mostly created by amateur developers or small startups with tight budgets - but their quality is surprisingly good, and in some cases as good as what the biggest movie studios were able to produce with huge budgets just a few years ago.

So what happened in the last five years, that turned special effects from being the exclusive domain of industry experts - into something a 14-year-old can create more or less at the touch of a button? Like the top end of a floating glacier, Deep Fakes are by and large only the visible product of a fascinating - and much deeper - technological revolution in the field of artificial intelligence. As we shall soon see, this revolution has the potential to put some very powerful tools in the hands of both attackers and defenders in the world of cyber-security.

0:00.0	Hi and welcome to malicious life in collaboration with Cyberism.
0:28.0	Forest Gump is considered one of the most successful films of the 1990s and has won several Academy awards. One of the most memorable scenes in the movie is one in which Forrest, the film's hero is invited to a reception at the White House.
0:38.0	During the reception, Forrest finds that his favorite soft drink, Dr Pepper, is served free, and so he drinks 15 bottles of it.
0:48.0	Sometime later, he's asked to shake hands with President John F. Kennedy.
0:53.6	The President asks him how he is, and Forrest tells him he has to pee.
0:59.2	Kennedy laughs, turns to the camera, and says, I think he said he has to pee.
1:04.8	This short scene, no more than 15 seconds long,
1:08.7	is considered a milestone in movie history,
1:11.9	because President Kennedy was at that point already
1:15.7	dead for several decades. It was one of the first times moviegoers got to see a
1:21.6	historical figure return to life on the big screen
1:25.2	thanks to computer-generated animation. 25 years later a short video is posted on YouTube in June 2019.
1:39.0	It's called Terminator 2 starring Sylvester Stallone.
1:43.4	And just as the name implies, it is a scene from the movie Terminator 2,
1:48.3	except that instead of Arnold Schwarzenegger,
1:51.4	the film's original star, we see Stallone stepping naked into a shady bar,
1:57.0	asking a tough-looking member of a Hell's Angels motorcycle gang to give him his clothes. I won't give you any spoilers, but let's just say this encounter
2:09.5	ends in a typical Schwarzenegger slash Stallone manner, i.e. everybody gets the shit kicked out of them.
2:17.0	This video is much more convincing than the JFK scene in Forrest Gump.
2:26.0	Looking closely at Kennedy in the movie, it's easy to see that his lip movements,
2:32.0	for example, don't match the rest of his face.
2:36.1	Fakes the loans, facial expressions in contrast are amazingly accurate.
