Une enqu\u00eate de KPMG indique que 62 % des gestionnaires de banques placent maintenant les failles profondes parmi leurs plus grands risques de s\u00e9curit\u00e9.

Une fois install\u00e9s, les programmes exigent de nombreuses autorisations. Ce faisant, les logiciels malveillants peuvent intercepter des mots de passe uniques (OTP) pour les transactions et d\u00e9tourner de mani\u00e8re autonome des sessions bancaires en ligne actives.<\/p>\n<h2>Co\u00fbts \u00e9lev\u00e9s pour le secteur financier<\/h2>\n<p>L&#8217;infrastructure des institutions est \u00e9galement assi\u00e9g\u00e9e.
