Monero recovers lost funds from ledger change output bug

The Monero (XMR) team has managed to recover the funds that were lost after a recent bug. A handful of users were affected by a vulnerability which prevented wallets from registering transactions.

In a Reddit post, the Monero team described the bug as the "ledger change output bug". A few weeks ago, a vulnerability in the blockchain's code had led to a number of transactions being "erroneously constructed".

The post explains that there are two different transaction public key formats, depending on whether the transaction is sent from a main address or a subaddress. The cause of the lost funds was "essentially that the Ledger Monero code used the first transaction public key format, whereas it should have used the second one. Therefore, the wallet was not be able to decode the change output, because it expected a different format of the shared secret."
