Discovered by Qihoo Technology in March 2017, the Two-tailed Scorpion, popularly known as the APT-C-23 threat group, surfaces again. The cyber mercenaries group targets victims of Middle East users and uses both Windows and Android components for its operations. A recent report from security researchers suggests that APT-C- 23 targets Android users with a new variant that boasts enhanced search capabilities and persistence features.
How Dangerous Is The New Malware Strain?
Unlike the other variants released so far, the new strain camouflages behind app icons. like Chrome, YouTube, Google Play, or the BOTIM voice-over-IP service. Moreover, the vulnerability of relying on a single C2 domain is fixed in the new variant. Now, the malware can switch to a C2 server with a different domain allowing spyware to continue operation even after the domain is taken down.
- When the user accessed the corrupt app icon, a genuine version of the app is executed in the background while performing surveillance.
- The new variant shares code with other malware samples linked with APT-C-23.
- Arabic language string was found in the code and some text is shown based on language settings on the victim’s phone.
Discoveries So Far
The spyware impersonates an updated app with a generic icon and words like System App Updates, App Updates, or Android Update Intelligence.
- To target users, a download link is sent via text message. When the user falls for it and taps the link, the spyware app is downloaded and launched. After that, to control the phone, it asks for permission; once that’s granted, threat actors have full access to the device.
- To enable required permissions, cybercriminals use social engineering, pretending that the permissions are vital for running the app.
- Once the permissions are granted, spyware masks itself using the name and icon of a legitimate app. This makes differentiating between the genuine and fake app difficult.
