    SandHook

    SandHook

    Android ART Hook/Native Inline Hook/Single Instruction Hook

    SandHook is an Android hooking framework built for intercepting Java methods inside the ART runtime. It supports object methods, static methods, constructors, system methods, and selected JNI methods. The framework can operate inside a process without requiring root access. Its native layer adds inline hooks, symbol-based hooks, breakpoints, and single-instruction hooks for low-level instrumentation. SandHook also provides compatibility with Xposed-style APIs, making existing hook modules easier to adapt. Supported architectures include ARM32, Thumb, and AArch64, with historical Android support spanning several major releases. The project has been used as a foundation for non-root Xposed environments and runtime modification research.

    SecureSandbox

    SecureSandbox

    EaseFilter Secure Sandbox Example

    EaseFilter Secure Sandbox was developed by a set of file system filter driver software development kit which includes file access control filter driver, transparent file encryption filter driver and process filter driver. The EaseFilter Secure Sandbox encompasses file security, file encryption, file monitoring, data loss prevention and process monitoring and protection. EaseFilter file system filter driver is a kernel-mode component that runs as part of the Windows executive above the file system. The EaseFilter file system filter driver can intercept requests targeted at a file system or another file system filter driver. By intercepting the request before it reaches its intended target, the filter driver can extend or replace functionality provided by the original target of the request. The EaseFilter file system filter driver can log, observe, modify, or even prevent the I/O operations for one or more file systems or file system volumes.

    SecureShareExample

    EaseFilter File Secure Sharing Example

    EaseFilter DRM Secure File Sharing example was implemented with the Transparent File Encryption and Control Filter Driver SDK. The shared file was encrypted with a unique 256-bits key, store the file access policies in a central server, share the encrypted files with fully control. You can grant, revoke or expire the file access at any time, even after the file has been shared. Digital Rights Management (DRM) enforces how files can be viewed, copied, printed, shared, or modified. Instead of granting blanket access, DRM attaches enforceable usage policies to content. With EaseFilter DRM, you can: Restrict access to authorized users, devices, and applications only. Block forwarding, uploading to unauthorized cloud services, or syncing to personal drives. Apply time-based access (expiration dates) and geo/device restrictions. Maintain tamper-evident audit trails for compliance and forensics.
