But we can see the recent ledger breach that have stolen bitcoin from many ledger wallet users, it is not only bitcoin that was only stolen altcoins were included. It has lead to many phishing attacks and also threatening emails that make hackers to promise of visiting ledger wallet people at their homes.
There hasn't been any breach that has led to users having their Ledger wallets hacked and funds stolen from them. Ledger databases got leaked and their customers started receiving phishing emails, just like you said. Those emails included fake Ledger Live wallets that requested the users to import their 24-word seeds. Those that did, had their coins stolen.
To sum up.
1. Ledger got it's database hacked that contained personal information on their customers.
This is Ledger's fault.2. Users got their crypto stolen because they installed fake wallets and inserted their recovery phrases in them.
This is the user's fault. There are many stories I have read online, another one is that a hardware wallet can be cloned, that means it is included with malware or vulnerabilities that will make people use the hardware and later lost their bitcoin to hackers that cloned it,
Don't you think that the possibility of this happening increases if more people are part of the supply chain?
If you buy the wallet from Ledger directly, you have the Ledger people being in contact with the wallet, you have the shipping agents who distributes it, and possibly customs officers.
If you buy from a reseller, you are making this circle bigger. Besides the subjects I already mentioned, you are also introducing the resellers and their people who could have access to the wallets.
