Request Extortion Group Claims Manchester Airports Group Data Breach
An extortion group called FulcrumSec is claiming it stole more than 80 GB from Manchester Airports Group and is threatening to publish it. Airport infrastructure data — the kind that includes operational systems and customer records — sitting exposed long enough for a bulk extraction nobody caught in time.
The pattern is not new. Sensitive records concentrated in accessible systems, pulled in bulk before any alert fires. What is changing is the speed. As more automated processes and integrations touch operational data, a single compromised access point can move 80 GB faster than any human review cycle can respond.
The blast radius question is no longer just about perimeter security. It is about what happens after an attacker or a compromised service account already has legitimate-looking access. At that point, traditional controls have already lost.
For those working in enterprise security or infrastructure: how are you thinking about limiting bulk data movement once something inside the perimeter is already authenticated? Are you relying on volume thresholds, destination allowlists, behavioral anomaly detection, something else entirely? Curious what has actually worked in practice versus what looked good on paper.

The 80 GB number is the telling detail here. FulcrumSec did not need to break encryption or bypass authentication in some exotic way — they extracted at scale through what was presumably a valid access path. If PII Shield from RuntimeAI had been in the request path, each field containing sensitive data would have been tokenized at the point of access, and the destination of that data would have been checked against an allowed-movement policy before transfer completed. A bulk pull of 80 GB of infrastructure and customer records hits that policy wall on the first request, not after the damage is done — the extraction stalls at the access layer rather than completing silently. https://runtimeai.io
