How Developers Can Tell Whether Traffic Spikes Signal a Real Data Breach

A common security disclosure phrase says traces of unauthorized access were confirmed, but the article explains how developers can check this themselves. A sudden spike in requests or data egress on a platform like Supabase often stems from internal problems such as buggy client code, heavy unindexed queries, or large unoptimized assets rather than an external attack. Row-Level Security can block unauthenticated reads by returning empty results with a 200 status, so request volume alone does not show data was stolen. The author recommends comparing request counts against egress, reviewing HTTP status codes such as 401, 403, and 429 for signs of automated probing, and checking the network origin of unfamiliar IPs. Together these signals help distinguish harmless internal issues from genuine exposure.
