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.

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.

- 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.
