AntiDot Threatens Android Users Globally
AntiDot, a dangerous Android malware, threatens over 3,775 devices since May 2024. Attackers use it in 273 campaigns for financial gain. For example, it targets users via phishing and malicious ads. This Malware-as-a-Service (MaaS) poses a serious risk to mobile security.
How the Attack Begins
Phishing emails or ads deliver AntiDot with tailored lures. It starts as an APK file with a three-stage process. Additionally, it prompts fake update bars for permissions. Consequently, it gains control over infected devices.
Malware Capabilities
AntiDot abuses accessibility services to record screens. It intercepts SMS and extracts data from apps. For instance, it overlays fake login screens on payment apps. As a result, it steals sensitive information easily.
Delivery and Obfuscation
The malware uses a Java core with heavy obfuscation. A packer loads missing classes dynamically during install. Moreover, it employs WebSocket for real-time C2 communication. This makes detection by antivirus tools challenging.
Global Reach and Targeting
AntiDot hits users in multiple regions with language-specific attacks. It operates 11 active C2 servers across campaigns. A report notes targets in Germany, France, and Russia. Therefore, its reach expands with localized tactics.
Impact on Victims
Victims face credential theft and privacy breaches. The malware blocks calls or snoozes alerts to hide activity. Additionally, it targets cryptocurrency and payment apps. This amplifies financial losses for users.
Evolution and Control Panel
AntiDot evolves with updates like AppLite Banker in December 2024. Its MeteorJS-based C2 panel tracks bots and injects. For example, it analyzes app usage for new targets. As a result, attackers refine their strategy continuously.
Broader Mobile Threats
Similar threats exploit weak permissions and overlays. They use dynamic loading to evade defenses. Moreover, localized phishing grows common. This highlights a rising trend in mobile malware sophistication.
Preventing AntiDot Attacks
To stop AntiDot, avoid suspicious app downloads. For example, verify apps from trusted sources only. Enable security updates and limit accessibility permissions. Additionally, install antivirus and monitor app behavior. These steps help protect Android devices from malware.
