Xkeyscore Source Code Exclusive Page

A 2014 investigation by Tagesschau and NDR, based on leaked source code, revealed that the NSA's XKeyscore program specifically targeted users of privacy tools like Tor and Tails. The report highlighted that the NSA monitored individuals, including German student Sebastian Hahn, who operated anonymity servers [1].

Analysts do not search a central hub. Instead, their queries are broadcast to all global nodes, which then report back matching results. 2. Technical Components & Logic xkeyscore source code exclusive

According to the configuration file ( config/xs_global.conf ), the system retains "FULL DATA" for 3 days, "SURFACE DATA" (metadata + payload previews) for 30 days, and "META ONLY" for 365 days. However, a commented line in the code ( // 5-eyes no deletion policy ) suggests that data marked as "Permanent Hold" never actually purges. A 2014 investigation by Tagesschau and NDR, based

: The "code" released consists largely of fingerprints —rules that contain search terms or regular expressions. For example: Searching for users visiting the Tor Project website. Identifying IP addresses of Tor "directory authorities." Tracking specific .onion addresses. Instead, their queries are broadcast to all global

I began to copy the most pertinent segments into my own encrypted notes. The architecture of the parser modules. The hardcoded IP addresses of the "Listening Posts" in allied countries—locations that were supposed to be classified Top Secret. The code revealed that the NSA wasn't just hoovering data from fiber optic cables; they had specific plugins for compromised routers in the infrastructure of foreign telecommunications companies.

The code includes an exploit for CVE-2017-0144 (EternalBlue) to deploy the agent on Windows 7 systems. While the exploit is old, the comment above it reads: // Legacy support for air-gapped targets via jump boxes. This suggests that XKEYSCORE is not just a passive listening post; it is an active persistence platform.

For the average internet user, the lesson remains unchanged: assume your traffic is logged. For the intelligence community, this leak is a disaster. For the historian, it is a roadmap of the early 21st century panopticon.
