A security breach of Uber Technologies temporarily hobbled the ride-hailing company’s internal communications in one of the starkest illustrations of how tech companies with access to the best talent and tools are vulnerable to repeated compromise.
Uber on Friday morning said it was continuing to investigate the incident, which began Thursday and prompted the company to take the preventive measure of suspending employee access to internal systems including Slack, Zoom and Gmail. Access to those systems was being restored as of Friday morning, the company said, adding that it had notified law enforcement and that it had no evidence that the incident involved access to “sensitive user data” such as riders’ trip histories.
