The National Security Service (NSA), the US intelligence service, eventually decided to create an official page at GitHub.
The NSA employs generalist coders and brilliant mathematicians who work to crack it codes, to collect information from everyone and to develop hacking tools like the EternalBlue which leaked from them Shadow Brokers in April and was used by the WannaCry ransomware last month.
The secret service works mostly underground, but after Edward Snowden's leaks the 2013, the NSA began (slowly) to exist for the world. He created a Twitter account the same year after the Snowden leaks and has now opened a Github account.
GitHub is an online service designed to share code between developers and the open source community. So far, the NSA shares 32 different projects under the Technology Transfer Program (TPP) of an NSA technology transfer program (TTP), some of which will come "soon".
"The Technology Transfer Program (TTP) works with innovative organizations who wish to use this collaborative model to transfer their technology to the commercial market," the service said on the program page.
Many of the projects made available by the service have been known for years and have been leaked on the Internet for some time. For example, SELinux (Security-Enhanced Linux) has been part of the Linux kernel for years.
Some of the NSA's open source projects are listed below:
Certificate Authority Situational Awareness (CASA): A simple tool which recognizes unexpected and disallowed authorization certificates on Windows systems.
Control Flow Integrity: Hardware-based technique to avoid exploits that target memory.
GRASSMARLIN: To understand the state of IP networks in networks ICS and SCADA and to support network security.
Open Attestation: A remote recovery and system integrity verification project using it unitTrusted Platform Modules (TPM).
RedhawkSDR: It is a software framework (SDR) that provides tools for the development and management of real-time radio software applications.
OZF Widget Framework (OWF): It is basically a web application that runs on Browser and allows users to create lightweight widgets and easily access all their online tools from one web page.
