Disney no longer trusts Slack after data breach
Slack's transition to Teams is being presented as a solution to cybersecurity concerns following the July incident.
NullBulge, the hacker group responsible for the incident, reportedly breached 10,000 Slack channels that included internal communications and sensitive information such as images, source code, and credentials. The information dated back to 2019.
However, many employees are concerned that the move is also aimed at cutting current costs. Many fear the transition could be fraught with complexities, such as the need for retraining and failed integrations.
