Popular cleaning products from Clorox may be hard to find in the coming weeks due to a cyberattack that hit the company.

According to regulatory filings Monday, The Clorox Company reported it detected unauthorized activity in some of its information technology systems last month, CNN reported. In response, Clorox immediately took action to stop the hackers, a move that included taking systems offline and reducing operations.

“The company implemented its business continuity plans and began manual ordering and processing procedures shortly thereafter at a reduced rate of operations. The company is operating at a lower rate of order processing and has recently begun to experience an elevated level of consumer product availability issues,” the filing noted.

It is not clear which products are impacted.

The process of returning to normal operations is expected to start next week but it’s unclear how long it will take to return to full production, CNN reported.
