Hacker: Turn off beauty filter for female anchors during live broadcast

The attack was a big mistake, but the truth was revealed.

Members of the Tsinghua University and Peking University team and Green Alliance Technology team pricked up their ears. They also wanted to know how Su Yang did it.

"I took advantage of a vulnerability in the phone..." Su Yang's voice came out from the big screen. His voice was through a voice changer, with a metallic texture that gave people a sense of mystery.

While speaking, the big screen showed the attack code written by Su Yang.

The audience at the scene naturally couldn't understand it.

The experts on the jury and the two groups of challengers watched very seriously.

"I hope that major mobile phone manufacturers can see our program, fix the vulnerabilities in time, and ensure the information security of the majority of users." The host Saning was speaking.

At this time, Su Yang interrupted, "In fact, there is a simpler way to crack it, and any audience member can do it."

"Oh, what method?" Saning asked curiously.

"Friends at the scene, who has an IC card? Bus card, community access card, subway card, phone card... It's all OK, who has it?" Su Yang said as he took out a white card from his pocket, on which the words were originally smeared.

"I have a phone card!" In the audience, a male student raised his hand and took out an IC card from his pocket.

"Please ask this student to come on stage." Saning said.

The male student took the IC card and walked onto the stage.

"Can a phone card be used?" Saning took the phone card from the boy and looked at LittleBoy.

"Okay." Su Yang nodded, picked up a mobile phone on the table, and showed it to the camera, "This phone is now in lock screen mode."

"Then, stick the IC card on the back of the phone for a few seconds." Su Yang said, while demonstrating to everyone, "Finally, tap the screen with your finger, hold it for about three seconds, and then release it."

Su Yang released his finger.

A miracle happened, the phone screen was unlocked.

"That's it?" Saning was surprised, this is too simple.

"Yes, it's that simple, host, you can let this student try." Su Yang said.

The boy took out his mobile phone after hearing this, turned on the screen, and it showed that it was in lock screen mode.

Then the boy took the phone card and followed Su Yang's example and stuck the phone card on the back of the phone.

"Then what?" The male student forgot the next step.

"Like this." Su Yang demonstrated tapping the screen with his finger.

The male student followed Su Yang's instructions and tapped the screen with his finger...no response.

Unlock failed.

"Try again. It's normal if it didn't work once."

The boy tried again.

Oh...it worked.

The phone screen was unlocked successfully.

This is magical.

"Let me try." Saning was curious, took out his phone and learned how to operate it.

"Ding!"

Unlocked successfully.

"Wow~~It's really unlocked!" Saning was amazed.

"Let me try too!" In the guest seats, Guo Qilin stood up, the boy walked over and handed over the phone card, took the phone card, Guo Qilin put the IC card on the back of the phone and tapped the screen with his finger.

It also worked.

"Wow, it's amazing!" Guo Qilin couldn't help but exclaimed.

"Wow!"

"It really works!"

"Incredible!"

...

The audience at the scene witnessed the "magical" scene and talked about it.

The phone card was passed to the hands of the experts on the jury by the staff.

Several experts took their own phones and tested it.

As a result, without exception, all of them succeeded.

The phone card was passed to the Tsinghua and Peking University team.

The four students were very curious.

"Ding!"

One of the students successfully unlocked his phone with the phone card.

"Wow, it really works."

"What is the principle?"

"The principle is very simple, using..." Su Yang spoke in a simple voice.

While he was talking, the three stars and the host in the guest seats came on stage, surrounded the table, picked up the mobile phone on the table, and tried to unlock it.

Su Yang's eyes fell on Pan Xiaoting, who was holding a Samsung Galaxy model mobile phone.

"Pan Xiaoting, is that a Samsung Galaxy phone in your hand?" Su Yang asked.

"Yes." Pan Xiaoting replied.

"Remind you, it's best to stay away from this phone." Su Yang said.

"Is there any problem with this phone?" Pan Xiaoting asked puzzledly.

"The battery of this Samsung Galaxy phone,

There is a major safety hazard. "Su Yang explained.

"Major safety hazard?" Pan Xiaoting looked at the phone in her hand again and said with a smile, "It won't explode, right?"

"It will really explode." Su Yang said.

"Ah?" Pan Xiaoting was startled and quickly put down the phone and stepped back. "It will really explode!"

The people next to him were also startled when they heard Su Yang's words and stepped back.

The attention of the whole audience was focused on the Samsung phone that Pan Xiaoting threw on the table.

"Don't panic, it won't explode immediately." Su Yang said with a smile.

"LittleBoy, are you saying that there is a problem with the battery of this Samsung phone?" The host Saning approached the table carefully and asked.

"Yes, there is a major security vulnerability in the battery of this phone." Su Yang repeated.

After the voice fell, Su Yang's ten fingers moved and tapped the keyboard.

"Everyone pay attention to the changes in the phone. ”

A camera above the studio aimed the lens at the Samsung phone on the table, gave a close-up shot, and projected the picture onto the big screen.

Everyone's eyes were focused on the big screen.

"It won't really explode, will it?" Guo Qilin said in surprise.

He then stepped back a meter or two, looking at the Samsung phone on the table from a distance, fearing that it would suddenly explode.

"Wait a moment, about a minute or so." Su Yang said.

At this time, the entire studio became quiet, and everyone held their breath.

Time passed by minute by minute.

"Host, you can pick up your phone." When the time was up, Su Yang spoke.

"It won't really explode, will it?" Saning was a little scared, and carefully reached out his hand and picked up the Samsung phone, "Oh!"

The next second, Saning hurriedly let go, and the phone fell to the ground.

"What's wrong?" Guo Qilin asked hurriedly.

"The phone is so hot!" Saning exclaimed.

"Hot? ”

Countless pairs of eyes in the audience curiously stared at the mobile phone on the ground.

The next second, an audience member stood up and exclaimed, "Ah! Smoke!"

"Wow!"

"Ah, smoke!"

Amid the exclamations, the Samsung mobile phone on the ground actually smoked.

In the guest seats, all ten experts stood up, their faces full of surprise.

The smoke was getting bigger and bigger, and it looked like a fire was about to start.

"Quick! Quick fire extinguisher!" The host Saning shouted.

A staff member rushed to the stage with a fire extinguisher.
