Ikea’s odd jobs marketplace TaskRabbit informed users on Monday it is investigating a “cyber-security incident,” asking them to reset their passwords. The security incident caused the company to temporarily take its app and website offline while it worked on resolving the issue.

TaskRabbit did not reveal details about the incident, but mentioned that it was cooperating with law enforcement and a cybersecurity firm to get to the bottom of the problem.

Ikea bought San Francisco-based TaskRabbit in 2017, although it is operated as an independent company within the Ikea Group. The app was founded in 2008 by Leah Busque.
