📚 Slack Now Strips Location Data From Images

Slack has started to strip uploaded photos of their metadata. What may seem like an inconsequential change to how the tech giant handles storing files on its servers, it will make it far more difficult to trace photos back to their original owners. From a report: Almost every digital file -- from documents on your computer to photos taken on your phone -- contains metadata. That's data about the file itself, such as how big the file is, when it was created, and by whom. Photos and videos often include the precise coordinates of where they were taken. But that can be a problem for higher-risk Slack users, like journalists and activists, who have to take greater security precautions to keep their sources safe. The metadata inside photos can out sources, deanonymize whistleblowers, or otherwise make it easier for unfriendly governments to target individuals. Even if a journalist removes the metadata from a photo before publishing, a copy of the photo -- with its metadata -- may remain on Slack's servers. Whether a hacker breaks in or a government demands the data, it can put sources at risk.
