However, it could put their security, privacy and safety at risk, especially for users living under authoritarian regimes in which apps like Keybase and Signal are increasingly relied on as a way to conduct conversations out of earshot of law enforcement or security services. Security Week Exclusive: Flaws in Zooms Keybase App Kept Chat Images From Being Deleted Paul Roberts, The Security Ledger. A formal security analysis of the Signal protocol was conducted in 2016. It comes as millions of users have flocked to apps like Keybase, Signal and Telegram in recent months. Jackson examined the client and saw that inside the Keybase uploadtemps and cache directories, photos that had previously been pasted into conversations were available and were not encrypted. According to that analysis, conducted by researchers from Germany, Switzerland, the United States, and Canada, there were no major flaws in the design. It showed that the protocol was cryptographically sound. Sakura Samurai researchers Aubrey Cottle, Robert Willis, and Jackson Henry discovered an unencrypted directory, /Cache, associated with the Keybase client that contained a comprehensive record of images from encrypted chat sessions. In a statement, a Zoom spokesman said that the company appreciates the work of the researchers and takes privacy and security 'very seriously.' The application used a custom extension to name the files, but they were easily viewable directly or simply by changing the custom file extension to the PNG image format, researcher John Jackson told Security Ledger. Keybase is a key directory that maps social media identities to encryption keys (including, but not limited to PGP keys) in a publicly auditable manner.

'We addressed the issue identified by the Sakura Samurai researchers on our Keybase platform in version 5.6.0 for Windows and macOS and version 5.6.1 for Linux. Keybase offers an end-to-end encrypted chat and cloud storage system, called Keybase Chat and the Keybase filesystem respectively. chicksdaddy writes: The Security Ledger reports that a flaw in Zooms Keybase secure chat application left copies of images contained in secure communications on Keybase users computers after they were supposedly deleted, according to researchers from the security research group Sakura Samurai.

Users can help keep themselves secure by applying current updates or downloading the latest Keybase software with all current security updates,' the spokesman said.

In most cases, the failure to remove files from cache after they were deleted would count as a 'low priority' security flaw.

However, in the context of an end-to-end encrypted communications application like Keybase, the failure takes on added weight, Jackson wrote.
