I’ve just read the report of Rucknium on the recent suspected attack.

(*TLDR)

I can’t avoid wondering

  1. who would do such a thing? Financial hackers? Western security agencies? Authoritarian regimes agencies? Private security contractors? Security researchers?

  2. which legal framework would various actors find themselves in for doing such a thing? While financial hackers and security contractors would probably be committing a crime if caught, would government agencies be allowed by their own laws to perform such an attack?

  3. which means/infrastructure are needed for such a thing (apart the few XMR fees). I guess some nodes, IP obfuscation tech, researchers and data analysis tools, what else?

  4. depending on the infrastructure used, what kind of fingerprinting analysis can be attempted to identify them?

(*TLDR):

  • XMR transactions at the start of March have largely increased.
  • An actor controlling this set of transactions could track most of what happens on Monero chain in the period.
  • This could have impacted the ring-signatures mechanisms effectively reducing ring-size and improving the probability of de-anonymization.
