Have you been getting scam texts with 'missed voicemails'?
I have started receiving weird text messages which are obviously a scam. I've had a few and they read something like this:
f03yo7b Voicemail:You have 1 new Voicemail(s). Go to https://hey-case.com/moscgy.php?c6rv46
It sounds dodgy right? Telstra have confirmed that they really are dodgy and that the messages are generated by malware called Flubot which spread via SMS and can infect insecure Android phones.
If you click on the link, you will be taken to a web page displaying a trusted brand and prompted to install an app, for example to listen to the voicemail message. If you give permission to install, then the malware will be loaded into your handset. Once installed it can harvest your contact list to further spread, as well as accessing your personal information and banking details if you use it while infected. Scary stuff, so whatever you do, dont open the link!
If you have received these types of messages, it doesn't mean your phone is affected. But if you have clicked on the link and downloaded the software, chances are your phone is now infected. If infected, you should urgently remove malware (or reset phone), change all passwords using another device that is not infected.
