El Salvador's state-run Bitcoin wallet, known as Chivo, was targeted by hackers who exposed sensitive information about the wallet. The hacker group CiberInteligenciaSV posted part of the source code on the black-hat hacking crime forum BreachForums on April 23.
This is the same group that leaked the personal data of 5.1 million Salvadorans just a few weeks ago.
"This time I bring you the code inside the Bitcoin Chivo Wallet ATMs in El Salvador, remember this is a government wallet and as you know we don't sell, we publish everything for you for free," the group said.
This follows a series of Chivo-related hacks reported in early April, including the public disclosure of the personal data of 5.1 million Salvadorans, almost the entire adult population of the country.
CiberInteligenciaSV also released the file Codigo.rar, which contains a compilation of codes and VPN credentials from the Chivo Wallet ATM network.
El Salvador made history in September 2021 when it became the first country in the world to accept Bitcoin as a legal tender. The government introduced Chivo as the official BTC wallet for its citizens, allowing users to buy and sell Bitcoin as well as store and withdraw BTC from ATMs.
