[1.2.0] - 2026-06-29

Third major release. The framework introduces indirect syscalls and significantly improves the execution pipeline's flexibility and operator experience.

Major Additions

• Indirect Syscalls: Architecture updated to decouple SSN resolution from invocation. Supports switching between direct and indirect syscall invocation dynamically.
• Gadget Finder (snd_syscall_find_gadget_scan): Dynamically locates the syscall; ret (x64) or OS-transition instructions (x86) from the natively loaded ntdll.dll in the PEB to properly masquerade the call stack.
• x86/x64 Support: Full indirect syscall assembly stubs for both architectures (invoke_indirect_x64.asm, invoke_indirect_x86.asm), including proper stack frame alignment and teardown.

Architecture & Refactoring

• Compile-Time Defaults (SND_USE_DEFAULTS): Added a CMake flag to pre-configure the pipeline's globals (invoker, gadget finder, and primary resolver). Implemented as a macro for OpSec to prevent linking unused scanner/ASM dependencies when disabled.
• Pipeline Overhaul: Replaced snd_syscall_strategy_set terminology with snd_syscall_set_resolver and added snd_syscall_set_invoker / snd_syscall_set_gadget_finder to manage the decoupled execution flow.
• Documentation: Extensive documentation overhaul across all primitives, examples, PoCs, and architecture files to reflect the new pipeline structure and OpSec considerations.

[1.1.0] - 2026-06-26

Second major release. The framework grows from a reflective-loader-centric engine into a multi-domain toolkit with expanded primitives, reorganized headers, and comprehensive documentation.

Major Additions

• Injection Domain: Introduced classic remote injection (snd_inj_classic_pe, snd_inj_classic_shell) driven by a shared snd_inj_ctx_t state machine.
• Expanded Primitives: Added Process and Mapping APIs (snd_proc_*, snd_map_*) and Object Manager support for \KnownDlls\ bootstrapping.
• Syscall Pipeline: Introduced pluggable syscall strategies (snd_syscall_resolve_ssn_scan, snd_syscall_resolve_ssn_sort).
• New PoCs: Added inject_shell and inject_pe to demonstrate stealth remote injection profiles.

Architecture & Refactoring

• Parsers Restructuring: Split parsing into pe/ and env/ (PEB walking) subdomains with a unified export resolver.
• Syscall Subsystem: Encapsulated NTDLL state; bootstrap now requires explicit snd_syscall_set_ntdll before direct syscall backends operate.
• Common Infrastructure: Split monolithic helpers.h and nt_defs.h into granular headers (memory.h, string.h, debug.h, nt/types.h, etc.) and added robust bounds checking.
• Loader Enhancements: Updated reflective loader to use snd_ldr_pe_ctx_t with explicit state tracking (snd_pe_target_t) and introduced new runtime FFI macros (SND_CALL_EXPORT).

Removals & Deprecations

• Removed legacy named gate resolvers (Hell's Gate, Halo's Gate, Tartarus, VelesReek) in favor of generic SSN strategies.
• Removed monolithic flat headers (helpers.h, nt_defs.h) and legacy parsing code.
• Removed implicit backend symbols (snd_mem_native, snd_mod_native) to enforce explicit _nt and _sys profiles.

[1.0.1] - 2026-06-22

Fixed

• Loaders: Fixed an access violation in native_load_library caused by resolving LdrLoadDll from an unmapped/disk NTDLL image. The loader now strictly resolves via the active PEB to maintain loader lock integrity.

[1.0.0] - 2026-06-22

SindriKit is a Windows evasion toolkit written in C. This first release provides the core engine, focusing on a Dependency Injection architecture that separates offensive techniques from underlying OS execution mechanics.

Major Additions

• Syscall Resolution: Dynamic SSN resolution with a cascading fallback pipeline supporting Hell's Gate, Halo's Gate, Tartarus' Gate, and VelesReek.
• Kernel-State Bootstrapping: Maps unhooked system modules directly from the \KnownDlls Object Manager directory.
• Reflective Loader: A fully functional 8-stage in-memory PE loader built on the framework, capable of executing entirely via direct syscalls.
• Algorithm Agility: Compile-time API hashing (DJB2 or FNV1A) via CMake.
• PE Parser: Custom, bounds-checked PE32/PE32+ parser with explicit state tracking (is_mapped).
• Dynamic FFI: Custom MASM assembly bridges for executing arbitrary functions safely.
