This is really dangerous, this indicates how easily can you be hacked and your hard-earned funds can be stolen from you just by the click of any suspicious link. And then you can be directly linked to any terrorist organization in the world. This guy had a large amount so went to the police but think if you had a smaller amount and you decide not to involve the police as they won't be able to help recover the money back. Whenever the government would find out your address they will easily declare you as a terrorist who is transferring funds to terrorist organizations in a suspicious manner. We should take care not to click any such links from our phones and report such incidences to prove our innocence.
I think the major fault here is with this individual who lost his money. I am sure this individual might have kept his crypto assets in a hot wallet and it has been always advised to use a cold wallet if the fiat value of crypto assets is so big. Once lost you cannot recover your crypto asset unless the individual who stole it sends it back which will never happen.
I don't think anyone used a cold wallet for a few lakhs. Everyone uses hot wallets for amounts upto 10-15 lakhs. You don't know his holdings he might be having a separate cold wallet for his larger corpus and might be trading this much amount on regular basis. The problem I feel here isn't about hot or cold, it's about the irresponsible behaviour of the user to click unwanted links. This can happen with anyone with a lower amount also, you just can't keep everything in your cold wallet.
