This emerges from a draft law, which NDR, WDR, and Süddeutsche Zeitung are reporting on again. The powers of the Federal Intelligence Service (BND) are to be extended as if the Snowden revelations had never happened. The foreign intelligence service could thus act more independently
The plans are also explosive in the area of active cyber espionage. Under the heading “Computer Network Exploitation”, the BND is to receive another official license to hack. If US tech giants like Google, Meta, or X do not cooperate with requests, the BND would be allowed to penetrate their systems secretly. This would even apply to IT infrastructures within Germany, provided it is necessary to defend against hostile cyberattacks. The line between domestic and foreign intelligence gathering would thus be difficult to maintain.
Average traffic for DE-CIX last year was 19.12 Tbit/s
Storing 30% of all traffic for six months would require:
19.12Tbit * 60s * 60m * 24h * 30d * 6m = 297,354,240 Tbit = 37,169,280 TB = 37.2 Exabytes of storage
I know they probably just want to scan this amount and save only the things that they are interested in but still, thats a lot of data.
