Our Government Has Weaponized the Internet. Here’s How They Did It
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.
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.
In this case, packet injection is used for “man-on-the-side” attacks — which are more failure-tolerant than man-in-the-middle attacks because they allow one to observe and add (but not also subtract, as the man-in-the-middle attacks do). That’s why these are particularly popular in censorship systems. It can’t keep up? That’s okay. Better to miss a few than to not work at all.
