>taking a number from the firm's name I'm lost as to what is meant here by "number". Are you saying the target firm was randomizing its iceberg order's component order sizes using the same seed? If yes, how could the target firm's usage of that seed be known by the "attacker" here?
The target firm had a number in their name, kinda like a16z or Office365. The attacking quant knew the target was using iceberg orders which split up and randomize parts of large orders. Attacking quant took a guess at an RNG seed by guessing they used the number in the target firm's name, and then somehow fit the resulting random number stream to order chunk sizes, and was able to confirm they used that number as a…

That... sounds amateurish. Everyone just uses a hardware RNG for random number seeds.

So in your world, if you’re willing to be X amount self-destructive or accept X risk, you’re also willing to accept X + Y risk or self destruction regardless of how large Y is. Got it.
No, I just expect that acceptance of X is correlated with acceptance of Y. (and really, much of the time, acceptance is the wrong word. Indifference or something like that often fits better)

8. Indicted for fraud
don't think this is fraud. Oil refineries aren't lying about their oil production to the general public. It's the hedge funds' fault for relying on their location data.

What about it is fraud?
The parts between "fake" and "profit".

#78How are they gathering this data? Are they placing detection equipment at/near the target locations to monitor for cell phone signatures in the vicinity, or are they gathering from mobile apps who resell location data to aggregation firms?

I heard that story from a quant friend. However, the way I heard the story, the targeted firm found out about their rival's attempt to game their strategy, and faked a bunch of activity. The rival's algorithm acted on the activity and placed a large market order...in the wrong direction.
This is called spoofing and is illegal.
