Hello, superstars, and welcome to CNN 10.

I'm Isabel Rosales, filling in for the big man, and I'm so excited to be here to share the best 10 minutes of news in this Summer Friday edition.

We begin today in the Middle East, where it has been one full week since Israel launched an unprecedented offensive attack on Iran.

The Israeli operation launched heavy airstrikes against

Iran's nuclear program and military leadership.

Iran's progress in developing nuclear weapons.

Iran struck back soon after, launching, quote, hundreds of ballistic missiles, and what state media said was part of a, quote, crushing response.

Israeli emergency services says dozens of people were injured in those strikes.

Since then, the two countries have continued to trade attacks.

As of this taping, Iran's latest wave of airstrikes damaged a hospital in southern Israel, plus several high-rise buildings east of Tel Aviv.

In Iran, dozens of Israeli fighter jets struck a nuclear facility southwest of Tehran during a series of nighttime raids.

Israeli Prime Minister Benjamin Netanyahu vowed that his country's operation would continue to target Iran's nuclear program.

But Iran insists its nuclear program is peaceful.

Our Tom Foreman breaks down what we know so far.

For decades, Iranian leaders have been building a nuclear program, which they say is for research and to generate electricity.

Indeed, just days ago, Iranian leadership reiterated they have no intention of building a nuke.

But intelligence and military analysts say Iran has long been stockpiling refined uranium, developing more powerful missiles, and mining the technical knowledge of allies, including Russia, with hopes of someday becoming the world's tenth nuclear-armed nation.

The Iranians are definitely much closer than they were five or ten years ago.

And it is certainly true that they've gotten a lot closer to deploying a weapon of this type than they were even a year or two ago.

Some analysts suspect it would pack about two-thirds of the explosive power of some bombs developed by the U.S. in the 1940s and 50s.

U.S. intelligence predicts a viable weapon could still be years away.

But the Israelis argue it might come much quicker.

We decided to act because we saw enough uranium and rich uranium for nine bombs.

And all they had to do was weaponize them.

Netanyahu did not offer specific evidence.

The Israelis have made such claims before.

And the complete equation is more complicated.

Any Iranian nuke would have to be miniaturized enough to be carried by a missile, plane, or other delivery mechanism.

It would need to evade Israel's robust detection and defense systems.

It could obliterate a large portion of a major city.

It could cripple communications, shut down electricity, and poison the land with radioactive fallout.

And so far, plenty of analysts note a lot of Iran's nuclear infrastructure is deep in the ground where Israeli bombs can't reach it.

Right now, Iran, if they were left alone, could reconstitute their program very quickly.

Again, the Iranians say they have no plans to produce a nuclear weapon, even as the Israelis say they just can't take their word on that.

They can't afford to be wrong about the nuclear aspirations of their old foe, not even once.

Now to a fascinating inside look at artificial intelligence and deepfakes, a manufactured video of a person in which their face or body has been digitally altered.

And fake, obviously addressing that the content is not real.

And as artificial intelligence gets better at creating more realistic deepfakes, the technology to detect them is not keeping pace with what is real and what is not.

Now I got to speak with a cybersecurity expert who showed me how this technology can fool deepfake detectors and what you can do to protect yourself.

I've just launched a new newsletter on how to get 10x returns on your crypto investments.

Deepfake technology is getting faster, cheaper, and more realistic.

Making it easier than ever to create scams or spread misinformation.

I was using just websites that had like a window, would let me upload your video that I wanted to clone, upload the audio that I'd created, and it would just mash those together.

Now it's really mere curiosity and a little bit of persistence.

AI companies have created deepfake detectors, but this cybersecurity expert says they have serious limitations.

Anyone that promises that one-click type of answer is wrong.

I can upload things that I know are deepfakes because I made them, and they'll say that they're likely authentic.

Maybe their hearts are in the right place, but I think that it has the very real potential of creating a false sense of security.

As a test, Carpenter ran my deepfake video through a detector that used several different models.

All the other ones, though, said no deepfake detector.

They're saying that it's in the green, no deepfake detected, and then one that's 56% suspicious?

Then we tried a different detector, this time using only my AI-generated voice.

Yeah, probability 98% that it was generated.

Yep, so it caught it, which is exactly what you had hoped for.

And then I'm going to add all the sound effects and everything else that's going to contribute to the story.

These sounds are like the interior car sounds.

Same audio clip that was 100% AI-generated, but you added some ambiance to it, and now it fooled it, and it thinks it's real.

I think somebody that's not thinking about this with nuance would go, oh, it's probably real.

Deepfakes are getting better and better, more believable, and the tools that maybe I thought would help me figure it out may not be so helpful.

It's not necessarily as hopeless as it might appear on the face of it.

There's security practices that have been around for decades, if not hundreds or thousands of years.

If we have set up some kind of code word,

It's simple human things like that that we're going to be able to use until the technology catches up.

In the sport of hockey, what is it called when a player scores three goals in one game?

Is it hat trick, power play, triple play, or shutout?

If you said hat trick, well, hats off to you.

Originating in the sport of cricket, it gained popularity when fans would collect money to buy the player who scored three points an actual hat to commemorate the achievement.

The Florida Panthers have just won the Stanley Cup for the second time in a row.

Back-to-back crowns have both come at the expense of the Oilers, this time in six games.

And Koi got a chance to go toe-to-toe with the Stanley Cup itself.

It is one of the most unique trophies in all of sports, named after Lord Stanley of Preston of the late 1800s, and it has some wild traditions.

The Stanley Cup, one of the coolest trophies in all of sports, in part because of the wild traditions, like the players avoiding it like the plague before winning it.

They think if they touch it, they'll be cursed.
