'Deleted files or folders keep coming back' can also be caused by a virus or malicious software. In the 'Permissions for SYSTEM' section, choose 'Allow' for all permissions. While the user is logged in to Keybase, that key is stored on disk in plain text (see tradeoffs below), or in the system keyring on macOS. Go back to the 'Security' tab, click 'Edit' to change permissions. Secret keys are stored on disk, in a file encrypted with cryptosecretbox, with a key derived from the users Keybase password. I'm think this PGP info is also stored on my Macbook Air. Chat signing keys are the device-specific cryptosign keys described above. Maybe if I had done keybase login on my Macbook Pro and authenticated with my Keybase passphrase instead of the paper key I chose (or the other option - "another device")?Ģ) I also have a PGP fingerprint node in my graph with my Macbook Air as a parent and a couple of social media accounts as children. I think that worked?ġ) For future reference, is it possible to start a new link from the very top of my graph, which is labeled keybase"? Right now the only thing connected to that is my now-deleted Macbook Air node. This left the Macbook Air in my graph, but it's now greyed and marked as "deleted". I then revoked my Macbook Air with keybase device remove. This added my Macbook Pro to my graph as a child of the paper key. Update: I installed the Keybase macOS app on my Macbook Pro and authenticated using my paper key (a child of my Macbook Air key, the "eldest key", in my graph). I don't feel like I have a good grasp about how everything ties together and the underlying system works. I haven't found the docs to be super helpful outside of the initial setup. Maltego, is an open source intelligence and forensics application. I'm a software engineer so I'm relatively comfortable on the command line, but I don't really ever work with crypto so PGP is pretty foreign to me (and I don't really understand what to use the keybase CLI for vs. The files SHA-1 hash is computed and stored in the blob object. The flaw in the encrypted messaging application ( CVE-2021-23827) does not expose Keybase users to remote compromise. I now have a new Macbook Pro that I'm replacing my Macbook Air with, and I'd like to move everything over to the MBP so I can comfortably wipe and sell the MBA.ġ) What's the best way to accomplish this? The original private key is on my Macbook Air, so I'm guessing I need to extract this, move it to my MBP, and then import it?Ģ) Do I need to "deauthorize" my MBA somehow? Right now it's at the base of my "graph", 1 level down from my keybase account, and everything else below is tied to it (social media accounts, PGP, paper). A serious flaw in Zoom’s Keybase secure chat application left copies of images contained in secure communications on Keybase users’ computers after they were supposedly deleted. I downloaded the Keybase app and basically followed the instructions in the docs to the letter, and opted to not upload my encrypted private key to Keybase. The flaw in the encrypted messaging application (CVE-2021-23827 ) does not expose Keybase users to remote compromise. This is a positive indication of how Zoom is treating Keybase following its acquisition and a step to attenuate the worries that the community had concerning the real intentions of the video conference company.I originally setup Keybase on my Macbook Air. A serious flaw in Zoom’s Keybase secure chat application left copies of images contained in secure communications on Keybase users’ computers after they were supposedly deleted. The bug bounty received by the Sakura Samurai team for this finding was $1,000, while the hacking group commented that Zoom was very responsive to their reports. The patched releases came out on January 23, 2021, so it’s been a full month already. If you are using an earlier version, make sure to update your Keybase client immediately. Thus, CVE-2020-23827 has already been reported to the firm and subsequently fixed with the release of Keybase 5.6.0 for Windows and Keybase 5.6.1 for macOS and Linux. The discovery of the flaws came thanks to Zoom's bug bounty hunting program when it acquired the project back in May 2020. These users may have their devices seized by the police for analysis so that the “physical access” part wouldn’t be far-fetched for a significant portion of Keybase’s userbase. This is very bad, especially for users who have picked Keybase specifically to stay safe from authoritarian regimes. Software, services, apps and privacy guides to fight surveillance with encryption for better. Thus, if an attacker manages to establish local access onto the user’s machine, they could potentially access files that have supposedly been securely erased on Keybase. The most reliable website for privacy tools since 2015.
