Ledger, in an update following last week’s attack, has promised to make users whole.

An attacker phished a former Ledger employee and was able to access the company’s package manager, where they uploaded a malicious code to ConnectKit. The attacker, according to Ledger, made off with $600,000.

“We commit, by any way possible, including gestures of goodwill, to make sure this is done by the end of February 2024. We are already in contact with many impacted users and are actively working through the specifics with them,” the company said in a post on X.

The company will make victims whole in the wake of the attack, and is working with law enforcement to track down the hacker and recover the funds.

“Ledger has engaged with authorities and is doing all we can to help as this investigation unfolds. Ledger will support affected users in helping to find this bad actor, bring them to justice, track the funds and work with law enforcement to help recover stolen assets from the hacker,” CEO Paul Gauthier said last week.

Following the attack, Tether froze the attacker’s address, which was also published to Chainalysis.

The attacker’s code was active for roughly five hours. Decentralized exchange SushiSwap alongside Revoke.cash warned that they were impacted. Ledger implemented a fix later the same day.

Additionally, the company plans to end blind signing by June 2024. When signing a transaction, “blind” refers to signing without the wallet offering full visibility or understanding of the transaction details.

In posts on X following the attack, the company pushed users to only use Clear Sign on their transactions.

“In the meantime, we’d like to remind the community to always Clear Sign your transactions — remember that the addresses and the information presented on your Ledger screen is the only genuine information,” Ledger said at the time.

“Our commitment is to work with the community and dapp ecosystem to allow Clear Signing so users can verify all transactions on Ledger devices before signing. This will lead to a new standard to protect users and encourage Clear Signing across dapps,” Ledger said Wednesday.

Ledger’s small display often requires paging through many — sometimes dozens — of screens showing encoded transaction details, which is why users often opted for blind signing.

The company warned that front-end attacks aren’t going away, so the “only foolproof countermeasure for this type of attack is to always verify what you consent to on your device…This is only possible with Clear Signing: meaning you can see and verify exactly what you sign on a secure display.”
