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.
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. It comes as millions of users have flocked to apps like Keybase, Signal and Telegram in recent months.
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. The flaw in the encrypted messaging application, CVE-2021-23827 does not expose Keybase users to remote compromise. But it did promise to lets its users know - with plenty of time - if anything would be changing with the availability of Keybase in general.Chicksdaddy writes: The Security Ledger reports that a 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, according to researchers from the security research group Sakura Samurai. It comes as millions of users have flocked to apps like Keybase, Signal and Telegram in recent months. The company told its own users that ".Keybase's future is in Zoom's hands," Keybase wrote on its blog. It supports, for example, Bitcoin wallets, but also has its own end-to-end encryption chat called Keybase Chat. Keybase is open source and works by taking social media identities and building encryption keys around this information. "We believe this will provide equivalent or better security than existing consumer end-to-end encrypted messaging platforms, but with the video quality and scale that has made Zoom the choice of over 300 million daily meeting participants, including those at some of the world's largest enterprises," said Zoom. Zoom was sued for allegedly overstating video chat security standards Hosts will have access to, and allocate, the encryption keys to clients and those who are attending the calls. Instead, this feature will be for paid accounts, said Zoom on its blog. Keybase Docker distribution Supported tags and respective Dockerfile links.

You can do a lot more if you turn a group into a team. If you turn a group chat into a team, you can add or remove people from it. Quickly, people started to look for other options, including Google Hangouts, now called Google Meet. Teams also allow you to organize chats by adding channels. The issue, with people gaining access to Zoom calls who aren't supposed to be there, grew rapidly as the number of people adopting Zoom during the coronavirus pandemic rose as well. The plan to is eventually have end-to-end to encryption inside Zoom, something that users may appreciate as well, as the service has been plagued with unwanted callers hacking into video streams, a phenomena now known as zoombombing. Video conferencing company Zoom has bought Keybase, an encryption firm, for an undisclosed price, looking to weave the technology into its video conferencing platform.
