Fiction or not, this is similar to an actual story of (ex)-fraud researchers at Capital One[1], who (ab)used their access to credit card transaction data in order to infer whether target companies' quarterly earnings would be below/above expectations, and then traded on that knowledge. However, in the actual story, there was no "black box" to query, the ex-employees wrote all the complicated queries themselves. EDIT:…
Can someone explain why this is illegal (besides any data/privacy breach within Capital One)?
