The Applied Crypto group’s research on password managers is now public at:
https://webro.ke/passwordmanagers
The paper, to appear at USENIX Security ’26, sees Matteo Scarlata, Giovanni Torrisi (former MSc student in AC, now doctoral student at USI Lugano), Matilda Backendal (former doctoral student in AC, now Professor at USI Lugano) and Kenny Paterson take a “Crypto in The Wild” look at Bitwarden, LastPass, Dashlane and 1Password.
Surprisingly, despite their popularity and the importance of the data they protect, password managers were not analysed in depth before.
When considering a malicious server threat model (the de rigueur approach for E2EE protocols), we found “a cornucopia of practical attacks” against the products we analysed.
The findings received wide press coverage: here we are on the ETH main page, on Ars Technica, Risky Biz and Medium
