Password managers less secure than promised
ethz.ch
Researchers from ETH Zurich have discovered serious security vulnerabilities in three popular, cloud-based password managers. During testing, they were able to view and even make changes to stored passwords.
  • 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.

    OMFG can people please fucking go away with this stupid “password managers are worthless” bullshit today. They are exactly as secure as promised, unless you went to the obviously shady ones that use web interfaces. People have been saying this for years, if you want security, keep your password manager offline.

            There is no way to patch the inherent flaw that comes with delivering client software through a web browser. If the entire client is delivered as a web page from a server you dont control, then that server can modify the software however it pleases. Same applies to e2ee encrypted chat clients that run as a web page like element-web (browser based matrix client).

              This comment shows that you know less about computers, than you may think. You can definetly make end to end encryption work using a Website. JavaScript runs client side. So as long as you trust the encryption algorithm (which in elements case you definetly can, because it is OSS), the encryption is safe and your unencrypted data never leaves the device.

                The point is you are trusting the JavaScript that the server delivered to you. If the server is compromised, it hands you compromised JavaScript and you’re screwed. It’s the exact same thing as going to evil.com and entering your master password. I think that you inherently understand that evil.com is untrusted. However, if passwordmanager.com is compromised by the same people who own evil.com. there’s really no difference.

                  I understand, but wouldn’t the same problem occur, if the server for the website you download your software from or the server for your package manager would be compromised? Even if you would buy your software physically on a CD, there would be a chance someone has messed with the content on a CD.

                  So I don’t really see this as a flaw unique to browsers. Am I wrong?
