Did Slack send you a password reset link last week? The company has admitted to accidentally exposing the hashed passwords of workspace users.<\/p>\n

The issue<\/a> occurred when a user created or revoked a shared invitation link for their workspace. The good news is that the password wasn’t plaintext, and it wasn’t visible in any Slack clients. The bad news is that it could be picked up by monitoring encrypted traffic from Slack’s servers, and it appears that all users who created or revoked those links between April 17, 2017, and July 17, 2022, are affected.<\/p>\n

Slack said only 0.5 percent of users were affected, which doesn’t sound too terrible until you consider how many Slack users are out there. While getting a definitive user figure for any chat platform is tricky and varies depending on what measure the vendor is using, it is safe to assume Slack has 10 million or more daily active users, meaning that at least 50,000 could have been affected. We asked the company to confirm this, and will update if there is a response.<\/p>\n
