![]() But LastPass disputed that in communications with Tom's Guide, saying that in 2018 "we implemented changes to our LastPass Android app to mitigate and minimize the risk of the potential attack." The researchers said that LastPass told them that fixing the rogue-app flaw was a low priority. "If a victim is tricked into installing a malicious app, it will be able to present itself as a legitimate option on the autofill prompt and have a high chance of success," Shahandashti said. Both password managers would see the app's file name and autofill the user's real Google credentials into the fake app. LastPass and 1Password were both successfully "phished" by a phony app the researchers created that simply shared the same file name as the real Google Android app. Its explanations are in italics throughout. UPDATE: After this story was initially published, Dashlane sent us a similarly detailed rundown of what it had done to address the various vulnerabilities outlined in the paper. 1Password had the fewest vulnerabilities with four, but in truth, none of the password managers came out with flying colors.įor its part, Keeper's Craig Lurey said in a very detailed blog post that Keeper "immediately processed and addressed all reported critical, high and medium-priority issues within 24 hours" of receiving the vulnerability reports from the researchers in 2018. From worst to just badĭashlane fared worst in the study, being vulnerable to seven different security flaws, including five that had been discovered in 20. And don't "sideload" Android or iOS apps from off-road app stores - use the official Google Play or Apple stores. Avoid using a PIN to quickly unlock the password manager's mobile app - use your fingerprint or your face. We still recommend that you use one of the best password managers, because it will permit you to make your passwords all unique and strong.īut make sure that the master password you choose is especially strong. In response to queries from Tom's Guide, representatives from all five password managers pointed out that the researchers' analyses were conducted two years ago, and that many of the flaws described in the paper had since been fixed, although not all of our questions were answered. "Because they are gatekeepers to a lot of sensitive information, rigorous security analysis of password managers is crucial." How you can make your password manager stronger We haven’t found anything unusual yet, but we’re still looking at it."Vulnerabilities in password managers provide opportunities for hackers to extract credentials," Shahandashti said in a University of York news posting. That’s why we’re making all these moves.Ī lot of the services on the servers that were involved have also been locked down as a precaution, and we’re still investigating on that end as well. ![]() The only thing we’re worried about is people that have weak ones. The real message needs to be that if you have a strong master password, nothing that could have been done would have exposed your data. In retrospect, we probably overthought this a bit and we’re maybe too alarmist ourselves. We think by taking those steps, we’re locking down any chance that somebody that guessed one of the master passwords would have any shot of getting in. Siegrist: When signing in, we’re forcing every user to prove to us that they’re coming from an IP that we’ve seen them come from before, or prove that they still have access to their e-mail. But if you used a dictionary word, that is within the realm of someone cracking it in a reasonable time frame. If you made a strong master password, you are pretty much in the clear–it’s not really an attackable thing. The threat is that once somebody has that process down, they can start running it relatively quickly, checking thousands of possible passwords per second. When you do all of that, what you’re potentially left with is the ability to see from that data whether a guess on a master password is correct without having to hit our servers directly through the website. Siegrist: You can combine the user’s e-mail, a guess on their master password, and the salt and do various rounds of one-way mathematics against it. What does all of this mean in terms of what was actually in that data and what someone could glean from it? PCW: We’re talking about blobs, hashes, and salts–a lot of phrases folks aren’t used to hearing. ![]() But we haven’t had any of those before, and we’ve been watching this a long time. Could this be just some kind of weird glitch? It could. ![]() We’re trying to look at what is the worst possible case and how we can mitigate any risks coming out of that.
