capa detects capabilities in executable files.
You run it against a PE, ELF, .NET module, shellcode file, or a sandbox report and it tells you what it thinks the program can do.
For example, it might suggest that the file is a backdoor, is capable of installing services, or relies on HTTP to communicate.
To interactively inspect capa results in your browser use the [capa Explorer Web](https://mandiant.github.io/capa/explorer/).
If you want to inspect or write capa rules, head on over to the [capa-rules repository](https://github.com/mandiant/capa-rules). Otherwise, keep reading.
Below you find a list of [our capa blog posts with more details.](#blog-posts)

# download and usage
Download stable releases of the standalone capa binaries [here](https://github.com/mandiant/capa/releases). You can run the standalone binaries without installation. capa is a command line tool that should be run from the terminal.
To use capa as a library or integrate with another tool, see [doc/installation.md](https://github.com/mandiant/capa/blob/master/doc/installation.md) for further setup instructions.
# capa Explorer Web
The [capa Explorer Web](https://mandiant.github.io/capa/explorer/) enables you to interactively explore capa results in your web browser. Besides the online version you can download a standalone HTML file for local offline usage.
More details on the web UI is available in the [capa Explorer Web README](https://github.com/mandiant/capa/blob/master/web/explorer/README.md).
# example
In the above sample output, we run capa against an unknown binary (`suspicious.exe`),
and the tool reports that the program can send HTTP requests, decode data via XOR and Base64,
install services, and spawn new processes.
Taken together, this makes us think that `suspicious.exe` could be a persistent backdoor.
Therefore, our next analysis step might be to run `suspicious.exe` in a sandbox and try to recover the command and control server.
## detailed results
By passing the `-vv` flag (for very verbose), capa reports exactly where it found evidence of these capabilities.
This is useful for at least two reasons:
- it helps explain why we should trust the results, and enables us to verify the conclusions, and
- it shows where within the binary an experienced analyst might study with IDA Pro
```

capa also supports dynamic capabilities detection for multiple sandboxes including:
* [CAPE](https://github.com/kevoreilly/CAPEv2) (supported report formats: `.json`, `.json_`, `.json.gz`)
* [DRAKVUF](https://github.com/CERT-Polska/drakvuf-sandbox/) (supported report formats: `.log`, `.log.gz`)
* [VMRay](https://www.vmray.com/) (supported report formats: analysis archive `.zip`)
To use this feature, submit your file to a supported sandbox and then download and run capa against the generated report file. This feature enables capa to match capabilities against dynamic and static features that the sandbox captured during execution.
Here's an example of running capa against a packed file, and then running capa against the CAPE report generated for the same packed file:
```yaml
$ capa 05be49819139a3fdcdbddbdefd298398779521f3d68daa25275cc77508e42310.exe
WARNING:capa.capabilities.common:--------------------------------------------------------------------------------
WARNING:capa.capabilities.common: This sample appears to be packed.
WARNING:capa.capabilities.common:
WARNING:capa.capabilities.common: Packed samples have often been obfuscated to hide their logic.
WARNING:capa.capabilities.common: capa cannot handle obfuscation well using static analysis. This means the results may be misleading or incomplete.
WARNING:capa.capabilities.common: If possible, you should try to unpack this input file before analyzing it with capa.
WARNING:capa.capabilities.common: Alternatively, run the sample in a supported sandbox and invoke capa against the report to obtain dynamic analysis results.
WARNING:capa.capabilities.common:
WARNING:capa.capabilities.common: Identified via rule: (internal) packer file limitation
WARNING:capa.capabilities.common:

# capa rules
capa uses a collection of rules to identify capabilities within a program.
These rules are easy to write, even for those new to reverse engineering.
By authoring rules, you can extend the capabilities that capa recognizes.
In some regards, capa rules are a mixture of the OpenIOC, Yara, and YAML formats.
Here's an example rule used by capa:
```yaml
rule:
meta:
name: create TCP socket
namespace: communication/socket/tcp
authors:
- william.ballenthin@mandiant.com
- joakim@intezer.com
- anushka.virgaonkar@mandiant.com
scopes:
static: basic block
dynamic: call
mbc:
- Communication::Socket Communication::Create TCP Socket [C0001.011]
examples:
- Practical Malware Analysis Lab 01-01.dll_:0x10001010
features:
- or:
- and:
- number: 6 = IPPROTO_TCP
- number: 1 = SOCK_STREAM
- number: 2 = AF_INET
- or:
- api: ws2_32.socket
- api: ws2_32.WSASocket
- api: socket
- property/read: System.Net.Sockets.TcpClient::Client
```
The [github.com/mandiant/capa-rules](https://github.com/mandiant/capa-rules) repository contains hundreds of standard rules that are distributed with capa.
Please learn to write rules and contribute new entries as you find interesting techniques in malware.
# IDA Pro plugin: capa explorer
If you use IDA Pro, then you can use the [capa explorer](https://github.com/mandiant/capa/tree/master/capa/ida/plugin) plugin.
capa explorer helps you identify interesting areas of a program and build new capa rules using features extracted directly from your IDA Pro database.
It also uses your local changes to the .idb to extract better features, such as when you rename a global variable that contains a dynamically resolved API address.
# Ghidra integration
If you use Ghidra, then you can use the [capa + Ghidra integration](/capa/ghidra/) to run capa's analysis directly on your Ghidra database and render the results in Ghidra's user interface.

You can run the standalone binaries without installation. capa is a command line tool that should be run from the terminal.\n\nTo use capa as a library or integrate with another tool, see [doc/installation.md](https://github.com/mandiant/capa/blob/master/doc/installation.md) for further setup instructions.\n\n# capa Explorer Web\nThe [capa Explorer Web](https://mandiant.github.io/capa/explorer/) enables you to interactively explore capa results in your web browser. Besides the online version you can download a standalone HTML file for local offline usage.\n\n\n\nMore details on the web UI is available in the [capa Explorer Web README](https://github.com/mandiant/capa/blob/master/web/explorer/README.md).\n\n# example\n\nIn the above sample output, we run capa against an unknown binary (`suspicious.exe`),\nand the tool reports that the program can send HTTP requests, decode data via XOR and Base64,\ninstall services, and spawn new processes.\nTaken together, this makes us think that `suspicious.exe` could be a persistent backdoor.\nTherefore, our next analysis step might be to run `suspicious.exe` in a sandbox and try to recover the command and control server.\n\n## detailed results\n\nBy passing the `-vv` flag (for very verbose), capa reports exactly where it found evidence of these capabilities.\nThis is useful for at least two reasons:\n\n - it helps explain why we should trust the results, and enables us to verify the conclusions, and\n - it shows where within the binary an experienced analyst might study with IDA Pro\n\n```\n$ capa.exe suspicious.exe -vv\n...\nexecute shell command and capture output\nnamespace c2/shell\nauthor matthew.williams@mandiant.com\nscope function\natt&ck Execution::Command and Scripting Interpreter::Windows Command Shell [T1059.003]\nreferences https://docs.microsoft.com/en-us/windows/win32/api/processthreadsapi/ns-processthreadsapi-startupinfoa\nfunction @ 0x4011C0\n and:\n match: create a process with modified I/O handles and window @ 0x4011C0\n and:\n number: 257 = STARTF_USESTDHANDLES | STARTF_USESHOWWINDOW @ 0x4012B8\n or:\n number: 68 = StartupInfo.cb (size) @ 0x401282\n or: = API functions that accept a pointer to a STARTUPINFO structure\n api: kernel32.CreateProcess @ 0x401343\n match: create pipe @ 0x4011C0\n or:\n api: kernel32.CreatePipe @ 0x40126F, 0x401280\n optional:\n match: create thread @ 0x40136A, 0x4013BA\n or:\n and:\n os: windows\n or:\n api: kernel32.CreateThread @ 0x4013D7\n or:\n and:\n os: windows\n or:\n api: kernel32.CreateThread @ 0x401395\n or:\n string: \"cmd.exe\" @ 0x4012FD\n...\n```\n\ncapa also supports dynamic capabilities detection for multiple sandboxes including:\n* [CAPE](https://github.com/kevoreilly/CAPEv2) (supported report formats: `.json`, `.json_`, `.json.gz`)\n* [DRAKVUF](https://github.com/CERT-Polska/drakvuf-sandbox/) (supported report formats: `.log`, `.log.gz`)\n* [VMRay](https://www.vmray.com/) (supported report formats: analysis archive `.zip`)\n\n\nTo use this feature, submit your file to a supported sandbox and then download and run capa against the generated report file. This feature enables capa to match capabilities against dynamic and static features that the sandbox captured during execution.\n\nHere's an example of running capa against a packed file, and then running capa against the CAPE report generated for the same packed file:\n\n```yaml\n$ capa 05be49819139a3fdcdbddbdefd298398779521f3d68daa25275cc77508e42310.exe\nWARNING:capa.capabilities.common:--------------------------------------------------------------------------------\nWARNING:capa.capabilities.common: This sample appears to be packed.\nWARNING:capa.capabilities.common: \nWARNING:capa.capabilities.common: Packed samples have often been obfuscated to hide their logic.\nWARNING:capa.capabilities.common: capa cannot handle obfuscation well using static analysis.

capa rules\ncapa uses a collection of rules to identify capabilities within a program.\nThese rules are easy to write, even for those new to reverse engineering.\nBy authoring rules, you can extend the capabilities that capa recognizes.\nIn some regards, capa rules are a mixture of the OpenIOC, Yara, and YAML formats.\n\nHere's an example rule used by capa:\n\n```yaml\nrule:\n meta:\n name: create TCP socket\n namespace: communication/socket/tcp\n authors:\n - william.ballenthin@mandiant.com\n - joakim@intezer.com\n - anushka.virgaonkar@mandiant.com\n scopes:\n static: basic block\n dynamic: call\n mbc:\n - Communication::Socket Communication::Create TCP Socket [C0001.011]\n examples:\n - Practical Malware Analysis Lab 01-01.dll_:0x10001010\n features:\n - or:\n - and:\n - number: 6 = IPPROTO_TCP\n - number: 1 = SOCK_STREAM\n - number: 2 = AF_INET\n - or:\n - api: ws2_32.socket\n - api: ws2_32.WSASocket\n - api: socket\n - property/read: System.Net.Sockets.TcpClient::Client\n```\n\nThe [github.com/mandiant/capa-rules](https://github.com/mandiant/capa-rules) repository contains hundreds of standard rules that are distributed with capa.\nPlease learn to write rules and contribute new entries as you find interesting techniques in malware.\n\n# IDA Pro plugin: capa explorer\nIf you use IDA Pro, then you can use the [capa explorer](https://github.com/mandiant/capa/tree/master/capa/ida/plugin) plugin.\ncapa explorer helps you identify interesting areas of a program and build new capa rules using features extracted directly from your IDA Pro database.\nIt also uses your local changes to the .idb to extract better features, such as when you rename a global variable that contains a dynamically resolved API address.\n\n\n\n# Ghidra integration\nIf you use Ghidra, then you can use the [capa + Ghidra integration](/capa/ghidra/) to run capa's analysis directly on your Ghidra database and render the results in Ghidra's user interface.\n\n<img src=\"https://github.com/mandiant/capa/assets/66766340/eeae33f4-99d4-42dc-a5e8-4c1b8c661492\" width=300>\n\n# blog posts\n- [Dynamic capa: Exploring Executable
