See [this repository](https://github.com/blackhillsinfosec/skyhook) for the source code. >- Download pre-built binaries [here](https://github.com/blackhillsinfosec/skyhook/releases) Skyhook is a pair of HTTP servers that coordinate [[Notes/File Streaming|streaming]] file transfers with web applications and CLI utilities. With the objective of thwarting network controls implemented to detect and block suspicious traffic, all data is passed through an [[Notes/Obfuscation Chain|obfuscation chain]] prior to being embedded in HTTP transactions. It's shipped with [[Notes/Embedded Web Applications|embedded web applications]] and [[Notes/Generate a Randomized Skyhook Configuration File|randomized configuration file generation]] capabilities to simplify usage. # Features - [[Notes/Round Trip Obfuscation|Round Trip Obfuscation]] - [[Notes/Obfuscation Chain|Obfuscation Chaining]] - [[Notes/Generate Self-Signed X509 Certificates|Self-signed]] and [[Notes/Obtain Lets Encrypt Certificates|Lets Encrypt]] certificate procurement methods. - [[Notes/Embedded Web Applications|Embedded Web Applications]] for both configuration and file transfers. - Server fingerprinting resiliency techniques: - [[Notes/Using the Encrypted Loaders|Encrypted loaders]] capable of dynamically encrypting interface files as the file transfer interface is rendered. - [[Notes/Generate a Randomized Skyhook Configuration File|API and web resource path randomization]]. # Getting Started - **[Download Skyhook](https://github.com/blackhillsinfosec/skyhook/releases)** - [[Start and Configure the Skyhook Servers]] - [[How Skyhook Works]] - [[Use Cases]] - [[High Level Skyhook Flowchart]] # Key Procedures - [[Start and Configure the Skyhook Servers]] - [[Notes/Getting Links for to the File Transfer Interface|Getting Links from the Admin Web Interface]] - [[Upload Files From Disk]] - [[Using the Encrypted Loaders]] # Key Diagrams - [[High Level Skyhook Flowchart]] - [[File Transfer Flowchart]] - [[File Transfer Sequence Diagram]] - [[Authentication Flowchart]]
