Slack will reset the passwords of users it believes are affected by a historical data breach that affected the company more than four years ago.
In 2015, the company said it was hit by hackers who gained access to its user profile database, including their scrambled passwords. But the hackers inserted code that scraped the user’s plaintext password as it was entered by users at the time.
Slack said it was recently contacted through its bug bounty about a list of allegedly compromised Slack account passwords. The company believes the case may relate to the 2015 data breach incident.
