Power Matrix at SkyLine Facility
REWARD +200 ptsBriefing
INTELSkyLine Data Center, Pod 4, 08:42 local. Thousands of high-density server stacks behind a single Building Management System. Breakers, coolers, automated failover — every amp accounted for, until it isn’t.
Our boundary scanners lit up on a rogue management interface exposed to an auxiliary network segment. No login prompt. No banner. It belongs to a legacy industrial Power Distribution Unit monitoring rack row 12.
The page doesn’t render a dashboard. It dumps the raw Modbus holding register map straight to the browser. Voltage, current, breaker state — and a block of unassigned registers a maintenance contractor used as scratchpad space during a recent firmware sync.
Watch the buffer. One block was rewritten on the fly. A duplicate transmission was overridden mid-stream, and the corrected payload sits one row below the broken one.
Objective
Modbus register dump and submit it as the flag.
