British engineering company IMI has disclosed a cybersecurity incident just days after its rival firm Smiths Group reported being targeted by hackers.

IMI, a Birmingham-based firm that designs and manufactures products for industrial automation, transport, and climate control, stated in a filing with the London Stock Exchange on Thursday that it is “currently responding to a cybersecurity incident involving unauthorized access to the company’s systems.”

The company has engaged external cybersecurity experts to investigate and contain the incident and is taking “necessary steps to comply with our regulatory obligations,” according to the filing.

When asked by TechCrunch, IMI declined to comment on the nature of the incident and hasn’t said whether any company data was exfiltrated. The U.K.’s Information Commissioner’s Office did not immediately respond to a request for comment.

U.K.-based engineering giant Smiths Group said last week that it was working to “recover” affected systems following unauthorized access to its network.

Neither company provided timelines for their recoveries.
