My colleague's mother suddenly received a call last year.

She said she was scammed. Someone impersonated her to deceive her.
The scammer called her, immediately calling her "Mom."
His voice sounded like hers, the tone was similar, even her catchphrases.
He said he was on a business trip, his wallet was lost, and he urgently needed 20,000 yuan.
He provided an account number.
She transferred the money.
After the transfer, she checked her phone.
She found her son's message.
She sent a voice message: "Did you receive the money?"
Her son replied: "What money?"
She said: "Didn't you lose your wallet on your business trip?"
Her son said: "I'm working overtime at the company. Not on a business trip. Call me now."
She panicked.
She called him.
He answered.
He confirmed it.
Then he called the bank to freeze the account.
They caught the scammer in time.
Later, he checked that account.
The account holder's name was his own.
It wasn't a scammer using a fake account.
It was opened with his own ID card.
He remembered losing his ID three years ago, reporting it lost, and reapplying.
The old one was sold online.
He stood outside the bank and sent his mom a message: "Mom, if I need money in the future, send a video. Don't send text."
His mom replied: "Okay."
He put his phone away, then reopened it.
He played the voice message again.
The one his mom said: "Did you receive the money?"
He listened to it three times.
