Une vaste campagne de faux modules d\u2019extension sur Firefox menace les d\u00e9tenteurs de wallet crypto. Selon Koi Security, plus de 40 extensions frauduleuses visent \u00e0 d\u00e9rober les identifiants des utilisateurs. Le risque s\u2019\u00e9tend \u00e0 toutes les plateformes majeures, et la sophistication de l\u2019attaque interroge sur la s\u00e9curit\u00e9 des investisseurs.<\/p>\n

Extensions pirates : le fl\u00e9au s\u2019\u00e9tend sur Firefox<\/h2>\n

D\u2019apr\u00e8s le rapport publi\u00e9 mercredi<\/a>, Koi Security a identifi\u00e9 plus de 40 modules<\/strong> malveillants imitant des outils wallet populaires. Les plateformes cibl\u00e9es incluent MetaMask, Coinbase, Phantom, Trust Wallet, Exodus, OKX, entre autres.<\/p>\n

Ces extensions, toujours actives pour certaines, apparaissent pour commettre leurs m\u00e9faits d\u00e8s avril 2025. Leur installation permet aux attaquants de siphonner discr\u00e8tement des donn\u00e9es sensibles. De ce fait, offrant un acc\u00e8s direct aux fonds des victimes sur diff\u00e9rents r\u00e9seaux blockchain les acteurs malveillants se servent<\/strong>.<\/p>\n

Le probl\u00e8me inqui\u00e9tant, ce sont les chercheurs qui alertent sur la dur\u00e9e et la technicit\u00e9 de cette campagne. Pour faire simple, les pirates adaptent sans cesse leurs m\u00e9thodes pour contourner les syst\u00e8mes de v\u00e9rification<\/strong> du navigateur. De plus, ces v\u00e9ritables poisons circulent toujours sur la boutique Firefox Add-ons, exposant les utilisateurs \u00e0 un risque constant.<\/p>\n

Ing\u00e9nierie sociale et sophistication technique<\/h2>\n

Pour tromper la vigilance, les fausses extensions affichent des centaines d\u2019avis positifs et de notes cinq \u00e9toiles. Ce faux vernis de l\u00e9gitimit\u00e9 incite les utilisateurs \u00e0 installer ces outils sans m\u00e9fiance.<\/p>\n

Leur apparence, leur nom et leur branding imitent fid\u00e8lement ceux des fournisseurs officiels de wallet. Cette imitation complique la distinction entre vrai et faux, rendant l\u2019arnaque redoutablement efficace.<\/p>\n

Koi Security vous permet d’identifier plusieurs indices techniques laissant penser \u00e0 un groupe russophone derri\u00e8re l\u2019op\u00e9ration. En effet, le code comporte des commentaires en russe<\/strong>, et des documents li\u00e9s \u00e0 l\u2019infrastructure de contr\u00f4le pr\u00e9sentent (comme de par hasard) des m\u00e9tadonn\u00e9es russes. M\u00eame si ces \u00e9l\u00e9ments ne constituent pas une preuve formelle, ils rappellent des modes op\u00e9ratoires d\u00e9j\u00e0 observ\u00e9s en Europe de l\u2019Est.<\/p>\n

Menace persistante et recommandations pour les investisseurs crypto<\/h2>\n

Enfin, le caract\u00e8re organis\u00e9 et \u00e9volutif de cette attaque laisse pr\u00e9sager d\u2019autres vagues sur d\u2019autres navigateurs ou plateformes crypto<\/a>. L\u2019op\u00e9ration ne rel\u00e8ve pas d\u2019un simple coup opportuniste, mais d\u2019une strat\u00e9gie durable et adaptable afin de nuire au maximum.<\/p>\n

Face \u00e0 ce risque, Koi Security recommande de ne t\u00e9l\u00e9charger des extensions que depuis les recommandations officielles des fournisseurs de wallets. Par exemple, Best Wallet<\/a>, un wallet s\u00e9curis\u00e9 et \u00e9volutif, non-custodial est t\u00e9l\u00e9chargeable ici en toute s\u00e9curit\u00e9.<\/p>\nD\u00e9couvrir Best Wallet<\/span><\/a>\n

Il convient de v\u00e9rifier l\u2019identit\u00e9 du d\u00e9veloppeur sur chaque page d\u2019add-on afin de ne pas se retrouver siphonn\u00e9 par ces faussaires vampires<\/strong>. Inspecter syst\u00e9matiquement les permissions accord\u00e9es \u00e0 une extension est \u00e9galement crucial pour ne pas se r\u00e9veiller un matin avec plus un<\/strong> seul jeton<\/strong>.<\/p>\n

En cas de doute, il faut d\u00e9sinstaller tout outil non reconnu ou jamais install\u00e9 sciemment. Le vieil adage s\u2019applique : il vaut mieux pr\u00e9venir que gu\u00e9rir, surtout dans un secteur dans lequel la s\u00e9curit\u00e9 des fonds d\u00e9pend de la vigilance de chacun<\/strong>.<\/p>\n
