The Weaponized Internet
November 16th, 2013Via: Wired:
The internet backbone — the infrastructure of networks upon which internet traffic travels — went from being a passive infrastructure for communication to an active weapon for attacks.
According to revelations about the QUANTUM program, the NSA can “shoot” (their words) an exploit at any target it desires as his or her traffic passes across the backbone. It appears that the NSA and GCHQ were the first to turn the internet backbone into a weapon; absent Snowdens of their own, other countries may do the same and then say, “It wasn’t us. And even if it was, you started it.”
…
Here’s how it works.
The QUANTUM codename is deliciously apt for a technique known as “packet injection,” which spoofs or forges packets to intercept them. The NSA’s wiretaps don’t even need to be silent; they just need to send a message that arrives at the target first. It works by examining requests and injecting a forged reply that appears to come from the real recipient so the victim acts on it.
