How did she contact this scammer? How does the scammer install TeamViewer on her phone?
Do they meet in person? Or did she install it with herself?
The bad thing she did why she allow someone to install any app on her phone it should have been personal no one should give access to your personal things like a phone especially if all your bank accounts and assets are on your phone.
If she didn't meet this scammer in person there's no way that she can find this guy and you can't reverse the transaction.
I'm sorry but no one here on the forum can able to help you or her with this case much better to report and seek help from local law enforcement or any cyber security agent that can able to track down this scammer.
Actually a mutual friend of her told her about this guy, that he is a nice person and so on. She belived the guy being friends, and he started to talk with the other guy about coinbase and so on. He asked her to install an app in her phone , so he could help her out with her account, he initially told her that he works for some king of blockchain agency in luxembourg...She started to trust the guy and installed the app , initially he wasnt doing nothing , but these 4 days he sended a pic of 92k$ in BTC holdings, saying that those money are for her, and that btc went to the moon so she can now take out the money, but before that he needs the OTP codes arriving so he can send em . Thats basically how she got rekt...in the transactions online, i saw a binance wallet, couldnt maybe make a complaint to binance directly so he gets the wallet on binance blocked ? have you seen some of the txs he made in these days starting from 03/11/2023 ? what you think ? thanks
Scammers are good at doing this, they are good at tempting their victims I have so many of these schemes on YouTube, they started with a recommendation so there's a possibility that your mutual friend is part of the scheme, so you should never give anyone access to your computer unless they are the nearest relative but someone from the other side of the world is such a big no, if the scammer is from your location you can file charges but if its outside, it's a long shot.
For readers who aren't aware of this scheme, this is an example of how they scam people when you give them access to your computer
This is why you never let anyone remotely access your computer
