A dangerous piece of Android malware is in the wild, hoovering up logins and MFA codes, sending financial data and screen captures back to the attackers – and more.
Here’s what Malibot does, how it spreads, and how you should protect your Android device against it.
What is Malibot Android malware?
A new strain of Android mobile malware was discovered by F5 Labs in June this year. The Malibot banking Trojan’s focus is on stealing financial information, credentials, crypto wallets, and personal data (PII). Read more about Malibot from the team at F5
Malibot abuses permissions and Accessibility Settings to intercept and send SMS messages, take screen captures, run and delete apps, steal cryptocurrency wallets, run and delete apps on demand and more.
If a user has an app on their device that matches one from a target list, as they open that app Malibot conducts an overlay attack. Malibot inserts an overlaid screen designed to look like the real one to harvest credentials or informatiom that the unsuspecting user enters into the app.
How does it spread?
There are 2 primary ways that Malibot spreads.
- Malibot lures victims to websites that present a download, sometimes pretending to be a download for a legitimate app you might find on the Google Play Store. The app users install contains the Malibot malware, and so far we’ve seen it disguised as popular cryptocurrency apps, the Chrome app and a Social Security app. However, Malibot’s Mining X campaign presents as a QR code on a website, and is not related to any Google Play Store app.
- The other way it spreads is via SMS phishing (smishing) as Malibot can send text messages on demand to the contacts on your device. It’s a fast and popular way for banking Trojans to spread, as we’ve seen from FluBot and SharkBot.
Why should we be worried?
Malibot can successfully inject overlays that look identical to the apps device users think they’re opening and logging into, so it hoovers up credentials and financial information before users know it’s there. Even security-savvy users that have set up multifactor authentication aren’t immune – Malibot intercepts MFA codes sent by SMS and even via the Google Authenticator app.
Its abuse of the Accessbility API, which allows an app to perform actions on behalf of the user, like read text on the screen, tap buttons, and listen for events, helps Malibot to prevent uninstallation or removal of its permissions.
Although Malibot’s main targets are currently online banking customers in Spain and Italy, its abilities in stealing data, spreading quickly, and evading detection make it a dangerous piece of Android malware that users must be on the look out for as threat campaigns expand and evolve.
