A modified version of DenDroid malware, WolfRAT, a remote access trojan (RAT) is preying on Android device users in Thailand. The new Trojan is targeting messaging apps such as Whatsapp, Facebook Messenger, and Line on Android devices.
What's all the hullabaloo?
- Recently, Cisco Talos discovered a new malware variant, WolfRAT, based on a previously leaked DenDroid malware.
- The research has found infrastructure overlaps and string references to an infamous organization, Wolf Research, that developed interception and espionage-based malware. The organization was highlighted by CSIS researchers during a presentation at VB2018.
How does the wolf hunt?
- The WolfRAT malware mimics genuine services such as GooglePlay Google service, or Flash update.
- When a victim is tricked, the RAT is installed on the target Android device to collect device data, steal photos or videos, compromise SMS messaging, and transfer files to a C2 server.
- The actor has not advanced and performs amateur actions, including open-source project copy/paste, code overlaps, the use of unstable packages, and unsecured panels.
Malware have always had a thing for messaging apps
- In 2019, researchers at Symantec found a malicious app named MobonoGram 2019. Detected as Android.Fakeyouwon malware, the app secretly loaded and browsed several ill-natured websites in the background.
- In December 2019, a trojan malware, dubbed CallerSpy, was found targeting Android users by tricking them into downloading a fake chat application. The mobile malware was designed to pry on calls, texts, and other communication methods.
- In 2018, an Android trojan horse malware was discovered by Trustlook Labs that used code obfuscation to steal data from Skype, Facebook Messenger, and many other messaging apps.
Avoiding security updates is one of the key factors that can expose Android phones to cyberattacks. While it may sound obvious, keeping your Android devices constantly updated is always a good idea.
