Dropbox two factor authentication

Since the Q-CERT site is 503ing: turns out that as long as someone has the username and password of your Dropbox account, they can bypass the two-factor authentication and log right into your account with a couple of clever tricks. Since Dropbox doesn’t verify email addresses when users sign up for a new account, a hacker can use a new email address that’s similar to an existing one by placing a period in somewhere, similar to how Gmail addresses work.For this fake account, two-factor authentication is enabled and an emergency code is generated in case users ever lose their phone. The hacker will then login to the victim’s account, but will be prompted to enter the code for that account. However, the hacker will simply select that the victim lost their phone and they’ll be promoted for that emergency code.Since the email address that the hacker signed up with is similar to the victim’s email address. the emergency code will work on the victim’s account. From there, the hacker can disable two-factor authentication and gain access into the victim’s Dropbox account. This is because that “[email protected]” is registered as being the same “[email protected],” just like how Gmail handles email addresses.Of course, you have to know the user’s password before you can do this, but once you get a hold of it, it seems relatively easy to bypass Dropbox’s two-factor authentication. However, the security team that found the vulnerability is already said to be working with Dropbox to fix the bug."

Interesting. It seems like there are two separate issues here:(1) Dropbox is inconsistent about whether it ignores dots in the local part of an email address, and in some cases blurs the line between accounts with similar emails. If true, this needs to be fixed.and(2) Dropbox doesn't really use two-factor authentication, in the usual sense of "something you know plus something you have." I'm guessing this is due to their users liking the idea of having two-factor authentication, but in practice want to be able to access their account even if their phone is lost. So it turns into "something you know plus something you know." I'm inclined to think that this kind of not-really-two-factor-authentication is actually the correct approach for the kind of data you store on Dropbox, but it's something to think about when you're designing an account-recovery protocol. Dropbox is a cloud provider that hosts critical information for many people. Given this nature of their business, I'd expect that security is actually their number one primary focus (even beyond new features I'd say).With regards to point number 1, I don't understand how that bug could have existed uncaught. Yes, security is hard but when you're storing the most personal user data, you're obliged to make sure you actually keep it safe and protect it from unauthorized access.Yet, with Dropbox, it appears that every so often that some time goes by, and we have yet another security issue. The worst I remember was when for a window of

Apps might not have the same level of security as Google Drive, making them potential entry points for attackers. To enhance security, adhere to the principle of least privilege and invest in advanced cloud security solutions.Comparing Google Drive Security to Other Cloud ServicesGoogle Drive vs. OneDriveWhen comparing Google Drive and OneDrive, both platforms are relatively secure. They rely on the cloud’s shared responsibility model, meaning users must play a key role in ensuring security. Google Drive and OneDrive both offer encryption and multi-factor authentication, but users need to configure these settings properly to protect their data.Google Drive vs. DropboxTrying to decide between Dropbox and Google Drive? This Google Drive vs. Dropbox showdown will help you pick the right tool for you. Both services provide strong security features, but Google Drive integrates more seamlessly with other Google services. Dropbox, on the other hand, is known for its user-friendly interface and robust file-sharing capabilities.Google Drive vs. iCloudGoogle Drive and iCloud both offer solid security measures, including encryption and two-factor authentication. However, iCloud is more tightly integrated with Apple devices, making it a better choice for users deeply embedded in the Apple ecosystem. Google Drive, meanwhile, offers more flexibility and compatibility across different platforms.Steps to Enhance Your Google Drive SecurityEnabling Multi-Factor AuthenticationTo make your Google Drive safer, enforce two-factor authentication (2FA). This adds an extra layer of security by requiring a second form of identification, like a text message code, in addition to your password. This way, even if someone gets your password,

Popular file-syncing service Dropbox just admitted to leaking an undisclosed number of user emails. Here's the word from Dropbox: [We] found that usernames and passwords recently stolen from other websites were used to sign in to a small number of Dropbox accounts. We've contacted these users and have helped them protect their accounts.A stolen password was also used to access an employee Dropbox account containing a project document with user email addresses. We believe this improper access is what led to the spam. We're sorry about this, and have put additional controls in place to help make sure it doesn't happen again.From the sound of things, if you've been receiving new, suspicious spam in your inbox, Dropbox could be the culprit. To be clear, it appears that no passwords were leaked directly from Dropbox. The stolen passwords alluded to were collateral damage from other web site hacks. (Like, say, the recent LinkedIn hack.)To improve their security, Dropbox is adding two useful user-facing features:Two-factor authentication is coming to Dropbox, reportedly in a few weeks. If you're not familiar with two-factor authentication, read our primer on why you should use it.A new Account Activity page shows you all the "computers, phones, and tablets that have access to your Dropbox." This is available now.Dropbox is also adding new methods of detecting suspicious activity, according to their blog post. As of this writing, Dropbox doesn't appear to be providing any way to check if your email may have been included in the leak.Security update & new features | Dropbox Blog
