Brunswick Corporation, the parent company of marine electronics group Lowrance, has shut down access to its app-based software and mapping updates to users.
The company reported overnight that it had been hit with “an IT security incident” without providing more details.
“Some of you may be experiencing certain systems issues, which could impact log-in to the Lowrance App for some users,” it said in a statement announcing the incident had occurred.

“Our teams are working to get everything fully operational as soon as possible and we sincerely apologise for the inconvenience.”
A notice posted to Brunswick’s website said the security breach “has impacted some of its systems and global facilities”. it is not known yet if Australian users, and users of Lowrance's Navionics app in particular, are among those affected,.
“The company has activated its response protocols, which include pausing operations in some locations, engaging leading security experts and coordinating with relevant law enforcement agencies,” it said.
“Brunswick is working to address the incident in order to restore the full functionality of the affected systems and minimise business, employee, and customer impacts.”

The company also posted a notice to the New York Stock Exchange notifying investors and the US sharemarket of the incident.
This is not the first time that a security incident has struck a marine-based manufacturer. In April last year BRP, the Canada-based maker of Sea-Doo jet skis, was crippled by a malware attack.
The attack forced BRP to delay jet ski deliveries until the issue could be resolved.
