Slack and Microsoft Teams have some rather worrying security flaws

Slack and Microsoft Teams, arguably the two biggest communications and online collaboration (opens in new tab) platforms around today, allow for the inclusion of hundreds of third-party apps, and that’s a security nightmare, experts have said.

Researchers at the University of Wisconsin-Madison argue that third-party apps rarely have their code reviewed by programmers at Slack and Microsoft. Even those that do, undergo a relatively superficial analysis, in which the reviewers analyze if the app works as intended, if it encrypts data, and run an automated scan that looks for vulnerabilities.
