Researchers uncover 27 attack scenarios targeting cloud password managers

Swiss researchers disclosed 27 attack scenarios across Bitwarden, LastPass, Dashlane and 1Password that could let attackers view or modify vaults, challenging the science of end-to-end encryption and exploiting issues in onboarding, key escrow, and item-level encryption. A notable attack demonstrated is ‘malicious auto-enrolment’ against Bitwarden, which could allow a server-controlled attacker to hijack a vault during organization onboarding. Vendors are patching (Bitwarden, LastPass, Dashlane) while 1Password defends its SRP-based design. The paper recommends stronger authentication, key separation and ciphertext integrity. Users should check remediation status with providers and ask for audits.)
