Ledger is a hardware wallet for cryptocurrency that is used to store, manage and sell cryptocurrency. The funds stored in these wallets are protected with a special 24-word phrase and an additional secret code phrase that only the owner knows (data for 2020).
2023: Transfer of secret keys to third parties for storage
Hardware wallet manufacturer Ledger released an update in May 2023 that transfers the secret keys of the wallet owner for storage to third parties. Thanks to this, now access to the wallet can be restored even if the user loses the key.
However, device owners began to lose confidence in devices.

The addresses of 270 thousand wallet owners Ledger are published on the hacker forum. This became known on December 21, 2020.
Ledger confirmed that the release of the stolen data is likely related to the June 2020 hack.
The attacker published stolen email addresses and postal addresses of users of the Ledger cryptocurrency wallet on the Raidforum hacker forum.
On July 25, 2020, hackers gained access to the company's database using an API key. The company immediately fixed the vulnerability and conducted an internal investigation.
Now the criminal has published an archive containing two files with stolen data. One of the files contains email addresses of 1,075,382 people who have subscribed to the Ledger newsletter. Another file contains the names and mailing addresses of 272,853 people who purchased the Ledger device.

2017: Ledger Nano S и Ledger Blue
Portable ultra-safe crypto wallets "Ledger Nano S" (flash drive wallet) and "Ledger Blue" (miniature tablet) have a built-in security chip. According to representatives of Ledger"," their products guarantee the security and confidentiality of crypto accounts and their owners.
Ledger uses a security principle similar to Apple Pay or Android Pay. All operations are closed inside the security element, so data on cryptocurrency transfers and the owner are completely confidential. The device conducts the transaction only after the user sends the original pin code. The portable wallet "keeps in touch" with the server and monitors the state of its firmware itself. Pins allow you to restrict access to account data in case of loss or theft.
The Ledger Nano S is the best-selling model from Ledger. The gadget supports bitcoins, ethereum, altcoins and costs about 70 euros. The price of the "tablet" version with improved functionality "Ledger Blue" is within 275 euros.
The developers want to double sales to 100 thousand copies and open additional production in China.
