Slack acknowledges it exposed hashed passwords for years

On Friday, Slack announced that one of its systems had been compromised but now has been fixed. The issue occurred in 2017 when a user revoked a link known as the "shared invite link". The command also unintentionally sent the link creator's hashed password to other users of that workspace, which they could use to sign up for a specific Slack workspace. This issue occurred due to a bug in the system. Anyone who created or deleted a shared invite link between April 17, 2017, and July 17, 2022, had their password affected by the bug.

The company alerted the impacted users on Thursday and mandated password resets for all of them, even though it's doubtful that any passwords' actual contents were leaked due to the problem. On July 17, 2022, a security researcher informed Slack of the problem. The company claims that the lost passwords were invisible throughout Slack and could only have been discovered by someone actively keeping an eye on relevant, encrypted network traffic from Slack's servers.

In a statement released by Slack, the company said they took immediate steps to remedy the situation and updated their users about the mishap. They took timely action as soon as the bug was discovered on July 17, 2022. It has also changed and reset the passwords for all the impacted customers.

The director of Cyber-threat intelligence at Scythe , Jake Williams, said that it was unfortunate that they face bug issues in 2022 as well. This is a threat and a result of a failed threat modelling system. He added that even though applications like Slack regularly perform security testing, the issue arises during the edge case functionality. However, the stakes are always high regarding passwords, which are susceptible to data.

Slack estimated that 0.5 per cent of its users were affected by the problem. The company reported having more than 10 million daily active users in 2019, which translates to about 50,000 notifications. The corporation may have almost doubled that number of users by this point. As a result, some users whose passwords were compromised over five years might no longer be Slack users.

The circumstance highlights the difficulty in creating adaptable and accessible web applications that also restrict access to valuable data like passwords. You should change your password if you received a notification from Slack, and make sure two-factor authentication is enabled. The user will have access to their account's access logs.
