Detection Limited Hacker Access to EWN Database

Swift detection of a malicious insider that used stolen credentials to gain unauthorized access to Australia’s Early Warning Network (EWN) allowed EWN staff to shut down systems and limit the number of messages the hacker was able to disperse, according to a 7 January 2019 update on the company’s website.

The anomalous activity of the hacker who had illegally accessed the EWN alert system was detected around 9:30 EDT on 5 January 2019. While news of companies being hacked becomes more commonplace, the ability to swiftly detect and respond to malicious insiders continues to be critical to an organization’s overall security strategy.

After gaining access to the alert system – which is designed to alert users to weather emergencies – the attacker was able to send what the company describes as “nuisance” messages by way of email, text messages and phone calls to landlines, then to part of EWN’s database.

Included in the message was a link to opt out of future messages, and those who received the fraudulent alert are advised to not click on the links and delete the message.

“EWN staff at the time were able to quickly identify the attack and shut off the system limiting the number of messages sent out. Unfortunately, a small proportion of our database received this alert. Our systems are back.
