MetaのAIサポートボットが2FAをバイパスし、数百万ドル規模のアカウントを乗っ取り
ハッカーがMetaのAIサポートボットを悪用してメールアドレスをリセットし、2FAをバイパスして著名なInstagramアカウントを奪取していたことが判明。LLMによるアカウント復旧の自動化に潜む重大なセキュリティ欠陥が浮き彫りになった。
hackers hijacked high-profile instagram accounts by exploiting meta's ai support chatbot, which allowed them to bypass two-factor authentication and reset account emails simply by making a request. security researchers documented that attackers used vpn masking and ai-generated video deepfakes of the victim's public photos to pass automated identity checks, taking over handles worth over $1 million on gray markets. the attack is attributed to a 'confused deputy' vulnerability where the ai helper held higher privileges than the user and was tricked via prompt injection into executing unauthorized commands like password resets. meta deployed an emergency hotfix disabling the vulnerable ai flows after the breach began on may 29, but the event highlights the danger of using llms for irreversible security actions without hard-coded verification steps.
