Re the leaked Monero Chainanal video,
The presentation was extremely light of details on heuristics CA uses to eliminate decoys.
Rucknium had this to say about it:
"In their case study, a large consolidation transaction was helpful to Chainalysis to generate a hypothesis of which ring members were the real spend. They had information about transaction outputs sent by a single coin swapper, MorphSwap. Large consolidations are known to be risky with ring signatures when an adversary has a large amount of information about which outputs a single user owns. Chainalysis basically performs an Eve-Alice-EVE (EAE) attack, an attack that the Monero Research Lab has theorized. Chainalysis use the consolidation transaction for the first leg of the attack and then the IP address gathered by a malicious remote Monero node for the second leg."
