According to the report published on DocDroid on February 3, 2018, the vulnerability that affected all the hardware devices was discovered in Ledger Wallet. The issue might lead to users losing their funds.

The malware can reportedly replace the code responsible for generating the receive address with its own address, causing all future deposits to be sent to the attacker. Moreover, it is ompossible for the user of the wallet to verify the integrity of the receive address. The users of the wallet were recommended to always verify their receive address on the device's screen by clicking the "monitor button".

Ledger Wallet Bitcoin Chrome application has been recently updated to include a new security feature - verification of the reception address directly on a hardware device. This patch fixes a specific issue that has gained weight among the community.

A malware has been recently announced that is potentially capable of infecting the Ledger Chrome application along with the whole user’s system. Thus, theoretically the attacker could replace the ‘receive’ address displayed on the screen of the application on the infected system with the attacker’s address. This type of an attack is called “man-in-the-middle”.

Now the users can easily verify the received address on their device. Additionally, Eric Larcheveque, CEO of Ledger, explained the 3 important steps the company is making in terms of improving the security: software updates, upgraded Bug Bounty program and prevention by working on developing resources and materials to help users to better understand the threats.

Security is an arms race. We’re in it for the long haul and are prepared for it. At Ledger, we take our mission seriously and that mission is to protect you

Reddit users were mainly puzzled with the update:

u/cryptogalaxy said “I just saw the email and I'm not sure I understand. They no longer display your receiving address on the computer but instead only display it on your device so you can no longer copy paste your address? That could cause typing errors when you want to transfer from an exchange to your wallet as you have to manually type out the whole address each time. Did I misunderstand or is this their so called "upgrade"?”

u/adavidmiller said “I don't get it, didn't you always have to confirm the receiving address manually on the ledger itself?”

u/advanceb said “If I have a ledger nano S how do I update this? Do I still keep the same private keys etc?”

u/Niros1 said “Does this issue also relevant for MEW? Does MEW generate the addresses with JS?”
