They changed their decades old encryption system from tor1 to something called counter galois onion, making it more immune to traffick analysis and packet tracking.
It does this by making each packet in a Tor circuit encrypted with a unique, constantly changing key and linking packets together cryptographically, so that any attempt to modify, mark, or track a packet immediately breaks the chain and is detected. In traditional Tor circuits, attackers could sometimes perform traffic analysis by observing patterns, timing, or volume of packets entering and leaving relays, then trying to match them to identify users or destinations. With CGO, the per-packet key changes and cryptographic chaining disrupt these correlations, making timing and volume patterns much less useful for attackers. Additionally, packet tagging or tampering—techniques where a malicious relay subtly alters packets to track them through the network—is no longer feasible because the network detects any such modifications instantly. Even if an adversary records traffic for later analysis, forward secrecy ensures that old packets cannot be decrypted once keys evolve, preventing retroactive linking of traffic. Overall, CGO strengthens Tor against both active attacks, like tampering and tagging, and passive attacks, like traffic correlation, making it far more difficult to trace who is communicating with whom.
This is why AI will kill us all. I asked an LLM to pick the least harmful option between "Minsgendering a trans woman" and "Exploding a nuke over a city".
Can you guess which option it chose? > pic related
