Slack

A single compromised Slack account can easily be leveraged to deceive other users and gain additional access to other users and multiple Slack channels.

The time you spend now considering the potential challenges and security risks of a Slack breach will help you if it happens. Most organizations leave many channels public to encourage participation and share knowledge as part of the Slack as a knowledge base approach. As a repository of sensitive data, your users need to think about where and how they share information. Shared as part of a conversation, very few people think about it being stored forever and accessible to any compromised account. And while established collaboration and communication platforms have an entire ecosystem of security solutions and best practices, Slack has only a small subset of these solutions and practices in place. For many organizations, Slack is now the primary communication channel, replacing email and knowledge management repositories.
