Missed delivery, call or voicemail (Flubot) scams

Body

Since August 2021, many Australians have been getting scam text messages about missed calls, voicemails or deliveries. We’ve received over 12,000 reports of these scams. These scams have also already been a problem overseas in 2021.

The text messages ask you to tap on a link to download an app to track or organise a time for a delivery, or hear a voicemail message However, the message is fake, there is no delivery or voicemail, and the app is actually malicious software called Flubot.

Android phones and iPhones can both receive texts from the Flubot.

If you receive one of these messages, do not click or tap on the link. Delete the message immediately.

What the scam messages look like

Scammers are frequently updating the Flubot text message format. We’ll update this page regularly, but we recommend that you check the @Scamwatch_gov Twitter account for the most up to date warnings about these messages.

Delivery notifications

Starting in September 2021, many Flubot messages now talk about a delivery. They usually refer to DHL and always ask you to take some form of action in relation to the ‘delivery’. We have also started to see reports referring to Amazon deliveries.

Messages can include:

  • scheduling a delivery time
  • tracking a delivery
  • managing a delivery that is ‘in transit’ or will be 'delivered soon'
  • telling you it's your last chance to arrange pick up/delivery of a parcel
  • asking you to enter your details to receive a package
  • getting 'more information' about your delivery.

Unlike earlier Flubot messages (which are also still circulating), the new text messages may not contain spelling mistakes, so they can be harder to spot. However, they do contain a website link followed by 6-8 random letters and numbers. Here are some examples:

  • The delivery time for your parcel is 03/09. Check out your options: http://example.com/g.php?l2r54ya alfal
  • Your DHL order ID1842225 will arrive soon. Track progress here

Voicemail and missed call notifications (August 2021)

Missed call and voicemail messages started circulating in Australia in August 2021. They often begin with 5-6 random lowercase letters or numbers, then say you had a missed call or voicemail message.

The text message often includes several misspellings. Here are some examples.

  • ab12c3 Nfw voice yessage received
  • gh6tr7 Voicemail message receiied
  • x78y9z New oozce-message received

After saying you have a missed call, voicemail or message, the messages include a link. The message may also say the voicemail message will be automatically deleted if you don’t access it.


Example: Android's spam/blocked folder with several scam messages

Example: A scam message saying that a voicemail message was received.

Example: A fake voice message notification on an iPhone

Example: A text message saying that the recipient missed a call.

Example: An iPhone notification showing a scam message about a missed call.

What happens if you click or tap the link

Clicking/tapping the link could lead to downloading malware (malicious software) to your phone.

Here's what each type of scam looks like.

For delivery texts

You'll see a screen with:

  • stolen DHL / courier branding
  • a button or link asking you to download an app to track your delivery's progress

The page sometimes says your phone may flag the app as suspicious and that you should ignore this warning.

For voicemail/missed call texts

You'll see a screen with:

  • your phone number
  • a note saying how long the fake message is (such as 2 minutes and 34 seconds)
  • a link to 'Download voicemail app' and instructions to enable the download of the application if this was blocked initially by your phone.

If you have an Android device

If you have an Android device, it will download an application called Voicemail71.apk or DHL34.apk. This application is malware.

You would then be asked to install the application.

The landing page that asks you to download the fake DHL application can look like this:

The application may be able to:

  • read your text messages
  • send text messages from your phone
  • make phone calls from your number
  • access your contacts

Installing the software is likely to give scammers access to your passwords and accounts. They may be able to use this information to steal your money or personal information.

It will also ask other infected Australian phones to send Flubot messages to the numbers it steals from your phone, continuing and expanding the scam.

If you have an iPhone

If you have an iPhone, you may see a link to download software. This software isn’t the same as Flubot, but it can still damage your device.

What to do if you’ve downloaded the Flubot

Act immediately. If you have already clicked the link to download the application, your passwords and online accounts are now at risk from hackers.

Don't enter any passwords or log into any accounts until you have followed the below steps. If you need to check your online banking, use a different device to do so.

Clean your device

Cleaning your device using the steps below will remove the malicious software from your device.

To clean your device, you can:

  • contact an IT professional
  • download official Android anti-virus software through the Google Play Store
  • perform a factory reset of the device, as soon as possible.

The best way to make sure that your phone is clean is to use the 'Erase all Content and Settings' or 'Factory reset' features. The exact name of the feature will depend on the device you have. Performing this reset of your device will delete all of your data including photos, messages, and authentication applications.

When performing a factory reset it's important that you don't restore from any backups created after you downloaded the app, as they will be infected.

Change your passwords and secure your information

If you have logged in to any accounts or apps using a password since downloading the app, you need to change your passwords.

If you have used the same passwords for any other accounts, you also need to change those passwords.

Contact your bank and ensure your accounts are secure.

How to protect yourself

  • Do not click on links in text messages saying you have a voicemail or missed call.
  • Do not call back the individual who sent the text. It’s unlikely that they are a scammer or criminal. Scammers can disguise their caller ID as legitimate numbers to carry out these scams. This is also known as spoofing.
  • Delete the message immediately.
  • Learn more about FluBot scams and other relevant phone scams at the ID Care website .
