Dashlane explains how attackers managed to download encrypted password vaults
Attackers exploited Dashlane's device enrollment API via 2FA spraying to download fewer than 20 encrypted vaults before automated lockouts. By distributing requests across thousands of accounts, they increased 6-digit OTP guess probability from 1/1M to 1/1K while evading rate limits, though Argon2 hashing still protects vault contents.
入选理由:攻击者滥用设备注册API进行2FA喷射,成功生成有效令牌并下载了少于20个用户的加密密码库。
