Who’s moving the cursor across your laptop screen? Because if it isn’t you, your device may have been hijacked by a scammer via Bluetooth.

Both the Australian and US governments have released warnings about a new vulnerability known as BlueBorne, which leaves millions of mobile phones, computers and IoT devices exposed to hackers.

“A remote attacker could exploit several of these vulnerabilities to take control of affected devices,” according to a statement from the United States Computer Emergency Readiness Team (US-CERT), a division of Homeland Security.

Android, Apple, Google, Microsoft, Samsung Mobile and Tizen have all been confirmed by US CERT as being affected.

“Affected users should consider disabling Bluetooth on affected devices if Bluetooth is unused or unnecessary,” US-CERT said.

The Australian Government followed up with its own announcement from the Hon Dan Tehan, the Minister Assisting the Prime Minister for Cyber Security.

Tehan said the government had notified device manufacturers about the BlueBorne, but was “not aware that it was being exploited”

“The vulnerabilities reported are concerning and device manufacturers have been notified and are working on updates to fix the vulnerabilities,” Tehan said.

“The Australian Cyber Security Centre recommends that all users apply the latest software security updates to their devices.”
