What do they do? They sent mail to Ledger customers from the leaked information to their mailboxes for them to update/upgrade their seed phrase, and failure to do so, their services will be terminated and they won't be able to access their wallet.
This is a standard way to scare the victim, make them nervous and stop thinking critically. The fear of losing their assets or access to them is the strongest among investors (thrifty people).
One X user reported yesterday that he received a mail from a fake Ledger company to update his seed phrase with the Ledger logo as letter head and a well-composed, organised mail. The details include a QR code that asked the user to scan and update his seed phrase; otherwise, he wouldn't be able to access his wallet and funds.
From the outside, this method of deception looks so naive and stupid, but it certainly turned out to be effective. Unfortunately, many buyers of hardware wallets are not properly informed about the rules for storing the seed phrase (don't disclose or show the seed phrase to anyone. including, never enter this seed phrase anywhere.).
Stay safe, as no company that offers hardware wallet safe services will send you such mail to your house;
But only if it is not the same manufacturer that is known for its incompetence.
There are so several data leaks of users information from the Ledger company that I don't doubt their incompetency.
I would say, in disregard and negligence for the safety of their users' data.
As you can see, ledger figures in this story. Ledger screwed up again.
