Appdome uses AI and a modular architecture to build, monitor, and respond with 400+ mobile app security, anti-fraud, anti-ATO and anti-bot defense plugins in Android & iOS apps on demand. Each mobile account protection plugin automatically adjusts to the code of the app and uses a dynamic defense model that analyzes behavioral anomalies, identifies threats, and filters out false positives, all without a server or external attestation. Let Appdome eliminate big Epics and manual work, handoffs, and resolutions in your mobile account protection journey!
Overlay attacks are fake or transparent overlay screens used in spyware and identity theft. In an overlay attack, the fake or transparent user interface (UI) is placed on top of legitimate apps, screens, fields and other elements in a mobile app to trick users into providing sensitive information or performing unintended actions. Overlay attacks have become the go-to method of mobile fraud, Account Take Overs (ATOs), credential theft, and password harvesting. Appdome detects and prevents overlay attacks, eliminating false positives from legitimate overlays, and gives mobile brands choices in enforcing defense options.

Keylogging attacks in mobile apps are a common tool in spyware and identity theft. These attacks secretly capture or record user keystrokes, often through malware or 3rd party keyboards installed on the device. Keyloggers are used to steal sensitive information such as usernames, passwords, credit card numbers, and other personal data entered. Appdome detects and blocks malicious keyloggers, prevents unauthorized keystroke logging in the app, and allows developers to trust approved keyboards, giving mobile brands and developers maximum flexibility in protecting their apps and users.

SIM swapping is a social engineering attack in which an attacker persuades the victim's mobile carrier to transfer a legitimate user's phone number to a SIM card controlled by the attacker. With access to the victim’s number, the attacker can reset passwords, intercept authentication codes (such as MFA passcodes or OTP tokens), and execute Account Takeovers (ATOs) for any app on the device. Appdome identifies when a protected mobile app is accessed using a non-recognized SIM card and either exits the app or passes the attack data back to the app for threat response.

Standard OS functions like screen sharing, screen recording, or screen mirroring can be used to carry our Identity theft, steal confidential data or spy on users in mobile apps. Detect spyware that records the screen, or abuses legitimate screen functions. Coverage includes zero day, unknown threats, and screen capture malware like StrandHogg and other variants. Appdome detects and prevents abuse of screen capture, screen sharing and screen mirroring applications and gives mobile brands choices on what and how to enforce the defenses.

DeepSeek AI and its clones extract and transmit sensitive user data, including financial details and account credentials, to unauthorized parties. Reports confirm DeepSeek acts as spyware, potentially sending unencrypted data abroad without consent. Appdome’s AI Native Detect DeepSeek AI Attacks plugin blocks DeepSeek from infiltrating mobile apps, detecting unauthorized file access, memory scanning, and data exfiltration in real-time. By preventing DeepSeek from accessing sensitive data, mobile brands ensure user privacy, account protection, and regulatory compliance—without SDKs, servers, or developer work.

Attackers use memory editing and dumping tools to extract encryption keys, modify app logic, and bypass security controls. Tools such as Frida, Cheat Engine, and GDB enable attackers to alter variables, intercept tokens, and disable protections at runtime. Appdome’s AI-Native Detect Memory Editing Tools blocks live memory modification, runtime hooking, and code injection, while Detect Memory Dumping prevents data extraction, binary dumps, and key theft. Together, they secure app memory and protect data integrity without SDKs, servers, or developer work.

Use memory protection to safeguard sensitive data in an app’s RAM during runtime, preventing unauthorized access or modification. Attackers use techniques like memory dumping to steal credentials, session tokens, or manipulate app behavior, such as altering game scores. Appdome’s dynamic Android & iOS Memory Protection plugins secure app-specific data like credentials and in-app purchase values, blocking unauthorized access, securing in-app transactions, and ensuring data integrity.

Spyware may intercept and monitor the content of the mobile device clipboard, where copied text or data is temporarily stored. This could include sensitive information such as passwords, credit card numbers, addresses, or other personal data. Spyware using the mobile clipboard can perform PII harvesting, stealing user credentials, crypto tokens and more. Appdome has several defenses that detect and block these actions, giving mobile brands choices on how and when to enforce each defense.

Android bootloader integrity is often reduced to a locked or unlocked state. This article explains why that model fails and how contextual bootloader signals improve identity and session trust.

For years, fraud prevention solutions have tried to use Device IDs to bind (or link) a user’s account or session to a specific device to prevent unauthorized access from other devices. However, until recently, Device IDs lacked persistence and the broad threat context needed to stop fraud and ATOs …
