Zilliqa a suspendu les transactions natives apr\u00e8s qu’une faille Ledger a expos\u00e9 des cl\u00e9s priv\u00e9es, tandis qu’Upbit a signal\u00e9 ZIL comme un actif de prudence \u00e0 l’\u00e9chelle mondiale.<\/i><\/b><\/p>\n

Zilliqa a suspendu les transactions natives apr\u00e8s avoir d\u00e9couvert une <\/span>vuln\u00e9rabilit\u00e9 critique de l’application Ledger<\/span><\/a>. Parall\u00e8lement, cette faille a r\u00e9v\u00e9l\u00e9 des cl\u00e9s priv\u00e9es et a provoqu\u00e9 une r\u00e9ponse imm\u00e9diate de la part des principales bourses de cryptomonnaies.<\/span><\/p>\n

Zilliqa g\u00e8le les transactions natives suite \u00e0 une vuln\u00e9rabilit\u00e9 critique de Ledger<\/b><\/h2>\n

Le probl\u00e8me a affect\u00e9 toutes les versions de l’application Zilliqa Ledger publi\u00e9es entre 2019 et 2026. De plus, les d\u00e9veloppeurs ont d\u00e9clar\u00e9 que la vuln\u00e9rabilit\u00e9 \u00e9tait activement exploit\u00e9e par des attaquants depuis le 19 juillet.<\/span><\/p>\n

Le probl\u00e8me venait de la g\u00e9n\u00e9ration d’un mauvais nonce dans l’application Ledger, a d\u00e9clar\u00e9 Zilliqa. Par cons\u00e9quent, les signatures de transactions r\u00e9v\u00e9laient suffisamment d’informations pour exposer les cl\u00e9s priv\u00e9es au fil du temps.<\/span><\/p>\n

Chaque nonce doit \u00eatre diff\u00e9rent pour chaque transaction de blockchain. Mais l’application Zilliqa Ledger mettait une partie du nonce \u00e0 z\u00e9ro.<\/span><\/p>\n

En cons\u00e9quence, l’al\u00e9atoire de l’application est devenu pr\u00e9visible, affaiblissant consid\u00e9rablement la s\u00e9curit\u00e9 des transactions. Ainsi, les attaquants pouvaient \u00e9tudier les signatures publiques et obtenir les identifiants des portefeuilles.<\/span><\/p>\n

Il a \u00e9t\u00e9 rapport\u00e9 qu’environ 5 transactions natives suffisaient pour r\u00e9v\u00e9ler une cl\u00e9 priv\u00e9e. De plus, les calculs pouvaient \u00eatre effectu\u00e9s par un ordinateur ordinaire en quelques secondes.<\/span><\/p>\n

Les utilisateurs concern\u00e9s par ces portefeuilles sur leur <\/span>Ledger<\/span><\/a> doivent imm\u00e9diatement cesser d’utiliser les adresses compromises, a d\u00e9clar\u00e9 Zilliqa. De plus, les cl\u00e9s priv\u00e9es ne pourront jamais \u00eatre s\u00e9curis\u00e9es \u00e0 nouveau car les signatures sont toujours publiques et resteront sur la cha\u00eene pour toujours.<\/span><\/p>\n

Pendant que les ing\u00e9nieurs travaillaient sur une solution permanente, le r\u00e9seau a suspendu toutes les transactions natives. Mais les transactions EVM ne sont pas affect\u00e9es et continuent de fonctionner sur la machine virtuelle Ethereum dans tout l’\u00e9cosyst\u00e8me.<\/span><\/p>\n

Upbit signale ZIL alors que les bourses suspendent les d\u00e9p\u00f4ts et retraits<\/b><\/h2>\n

La bourse sud-cor\u00e9enne <\/span>Upbit <\/span><\/a>a class\u00e9 ZIL comme un actif \u00e0 surveiller. Par cons\u00e9quent, la bourse a suspendu tous les d\u00e9p\u00f4ts et retraits sur les deux march\u00e9s de trading, KRW et BTC.<\/span><\/p>\n

Upbit a \u00e9galement d\u00e9clar\u00e9 que le support de trading pourrait \u00eatre interrompu si Zilliqa ne r\u00e9sout pas le probl\u00e8me. Par cons\u00e9quent, l’\u00e9quipe de d\u00e9veloppement est sous une pression croissante de la part des utilisateurs et des bourses du monde entier.<\/span><\/p>\n

Parall\u00e8lement, d’autres bourses ont r\u00e9agi rapidement \u00e0 l’incident de s\u00e9curit\u00e9. Pour garantir la s\u00e9curit\u00e9 des clients de Binance et KuCoin, les d\u00e9p\u00f4ts et retraits de ZIL sur les deux plateformes ont \u00e9t\u00e9 temporairement suspendus. <\/span>Binance <\/span><\/a>et KuCoin ont temporairement suspendu les d\u00e9p\u00f4ts et retraits de ZIL pour prot\u00e9ger les fonds des clients, comme demand\u00e9 par Zilliqa.<\/span><\/p>\n

La premi\u00e8re alerte est venue lorsqu’un partenaire de la bourse a rep\u00e9r\u00e9 le vol de jetons ZIL. Les enqu\u00eateurs ont ensuite retrac\u00e9 le vol jusqu’aux cl\u00e9s priv\u00e9es g\u00e9n\u00e9r\u00e9es par Ledger dans les transactions natives.<\/span><\/p>\n

La nouvelle de la vuln\u00e9rabilit\u00e9 a provoqu\u00e9 une r\u00e9ponse rapide du march\u00e9. Par cons\u00e9quent, ZIL a chut\u00e9 d’environ 10 % et se n\u00e9gocie actuellement autour de 0,0024 $ lors des r\u00e9centes sessions de trading.<\/span><\/p>\n

Cependant, l’incident rappelle la n\u00e9cessit\u00e9 d’auditer r\u00e9guli\u00e8rement les int\u00e9grations de portefeuilles mat\u00e9riels. Les \u00e9cosyst\u00e8mes blockchain plus petits pourraient \u00eatre plus vuln\u00e9rables lorsque les vuln\u00e9rabilit\u00e9s ne sont pas d\u00e9tect\u00e9es pendant de longues p\u00e9riodes.<\/span><\/p>\n

De plus, Zilliqa a exhort\u00e9 les utilisateurs \u00e0 g\u00e9n\u00e9rer eux-m\u00eames de nouveaux portefeuilles avant de transf\u00e9rer des actifs. En attendant, les membres de la communaut\u00e9 attendent toujours des mises \u00e0 jour sur le moment o\u00f9 le support des transactions natives sera r\u00e9tabli sur l’ensemble du r\u00e9seau et sur tous les audits de s\u00e9curit\u00e9 n\u00e9cessaires \u00e0 effectuer \u00e0 l’avenir.<\/span><\/p>\n

Parall\u00e8lement, l’incident Zilliqa pourrait servir de catalyseur pour des audits de s\u00e9curit\u00e9 plus complets dans le secteur des cryptomonnaies. En attendant, les investisseurs surveilleront de pr\u00e8s la mani\u00e8re dont le r\u00e9seau se remet et comment les futures transactions seront effectu\u00e9es dans le monde entier.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
