Work Chat Apps Become Hacker's New Backdoor

A new cybersecurity trend shows attackers are increasingly exploiting collaboration tools like Slack, Teams, and Zoom as backdoors into corporate networks. These platforms, once trusted for internal communication, are now being targeted for phishing, data exfiltration, and unauthorized access. Security experts warn that the same features that enable productivity—file sharing, integrations, and chat history—can be weaponized. Organizations must enforce strict access controls, monitor for unusual activity, and educate employees about the risks of sharing sensitive information in chat apps.
