erikalui, I agree that we should be extra careful when it comes safety of our coins, but we should not exaggerate is some things. What I'm interested in this story is whether you do not trust Ledger as the company or Swissborg?

I'm not too technical to say how easy or difficult is modify Nano S hardware, but I believe it is not easy, or a cheap process. Such attack would probably aim on user with significant amount of coins, a not on a random users.

Good way of testing hardware wallet would be to create wallet, and then deposit smaller amount of coins in such wallet. If device is compromised coins would move from your wallet in case hacker is not patient enough to wait that you deposit more.

I trust both Ledger and Swissborg but I am not sure if Swissborg bought it from a reseller and I have read many cases of resellers selling tampered Ledger Nano S which is why I wanted to confirm if the hardware is also safe to use. Will try sending few coins first and will see what happens. To check the hardware, I just need to use a screwdriver to open the behind case and Ledger has given instructions to do so but I want to do it from a technician who can be more careful. Random users have lost $35k from such hacks.

The Ledger Live verifies only the software part of Ledger devices does it not? In order to check the individual hardware components and compare them to the official pictures posted by Ledger on their site you would have to actually open your device, like you said, and inspect each individual piece.

I wanted to ask if we need to check the hardware as well as Ledger has given instructions to do so but I don't want to tamper with the device as it may break. Is it necessary to check the hardware as well?

Well, this depends on how safe you want to be.

Since the firmware will be checked once you access your nano s via ledger live, the only option which could pose a risk would be tampering with the hardware.

Do you trust the person who gifted you the nano s ? Was it a friend / relative ? Or some stranger ?
Does the case of the nano s look untouched ?

It requires quite some technical know-how to get and set up the required hardware and build it into the nano s to compromise the device.

Usually (if you got it from a friend / relative), are not paranoid and don't want to store a massive amount of BTC on it, it should be fine without checking the hardware (my personal opinion).
But if you want to be 100% sure or got it gifted from an unknown / not that trustworthy person, i'd check it.

I won it in a competition held by Swissborg. The case of nano s was untouched.

I'll try to get it checked from a good technician but since it has no screws like a laptop, it could damage the device of which I am scared. The Ledger Live app helps to detect genuine devices but if that's no enough, I would be left to open the device to get full confirmation.

I checked out some Youtube videos and noticed that fake Ledger Nano devices have costed many users to get scammed. I received my Ledger Nano S as a gift and wish to know whether it's genuine or a fake one.

I already verified these steps given by Ledger: https://support.ledger.com/hc/en-us/articles/360002481534-Check-if-device-is-genuine

There was nothing suspicious found in sheets and I myself set the PIN and 24 words recovery phrase. I wanted to ask if we need to check the hardware as well as Ledger has given instructions to do so but I don't want to tamper with the device as it may break. Is it necessary to check the hardware as well?
