Over the weekend, a hacker gained unauthorized access to the Queensland EWN, or Early Warning Network, and used it to send a spam alert via SMS, landline, and email to the company’s subscribers.
EWN is a service offered by Australian company Aeeris that allows Australian councils, or local governments, to send emergency alerts regarding extreme weather, fires, evacuation information, or incident responses.
The unauthorized alerts stated that “EWN has been hacked. Your personal data is not safe.” They then went on to tell recipients to email email@example.com to unsubscribe from the service. An example of one of the alerts can be seen below.
