Slack breaches recur because attackers harvest chat history, abuse apps and sessions, and exploit culture not bugs: attackers buy a Slack session cookie for $10, use that persistent web session to join IT channels, reset SSO credentials and exfiltrate source code (EA/Uber/Twitter examples) or post ransom notes; Slack has ~2,400 apps with ~10% official authors, channel defaults are public, and Audit Logs off by default and costly so defenses rely on exports and scripted backups plus default channels are public and tighter app approvals.
