- Millions of people use password managers. They make accessing online services and bank accounts easy and simplify credit card payments.
- Many providers promise absolute security – the data is said to be so encrypted that even the providers themselves cannot access it.
- However, researchers from ETH Zurich have shown that it is possible for hackers to view and even change passwords.


From what I scanned, there was no reason given on why they only attacked cloud based providers.
My guess is that these are paid ones and thus have a ‘market share’, easier to attack etc.
If you attack a ‘keepass’ password the attack vector is more crypto / memory based as far as my limited knowledge goes and not some funky inbetween attack.
Also, if you attack a cloud base provides, you will most likely have multiple victims per breach / exploit, whilst offline are targeted and thus not so interesting in most cases unless we’re talking about a person of interest
they ran the test on those pw managers because they were open source. that allowed the testers to implement a “dummy” provider on their own “compromised server.” so the results of failing the tests are based on the hypothetical situation of “what if bitwarden (or whoever) had an entire server taken over by hackers”. while the possibility of that happening are greater than zero, it would take a lot for someone to completely hijack a server like that
Oh okay so they probably delivered malicious code to the user entering their passwords… Well even an offline pw manager can be compromised in the code.
