I’d avoid anything related to Cake Wallet (e.g. its remote nodes), seeing that the OP sgp = SamsungGalaxyPlayer is doing this side business—chain analysis, offering suspicious activity reports for CEXes, ready to collaborate with law enforcement if paid.

In 2022, it was noticed that someone from Team Cymru, a company trading net flow data, was a board member of the Tor Project, providing bandwidth, hardware, bridges (entry points to the Tor network). There was a fix: Remove Team Cymru hard-coded bridges.

Now “Moonstone Research” is proudly saying they can trace things that other companies can’t, and they’re related to Cake Wallet directly or at least indirectly, or so it seems.

This possible suspicion aside, the analysis itself is interesting. While it might be good news if we can identify the attacker, that would be actually very bad news for Monero!
