# FulcrumSec claims Manchester Airports hack, theft of 86 GB of data

**[BleepingComputer](https://daily.dev/sources/bleepingcomputer)** · 4 min read · 0 upvotes · 0 comments

## Summary

Extortion group FulcrumSec claims responsibility for the Manchester Airports Group breach, saying it stole roughly 86 GB of data, including a 21.5 GB customer export and nearly 200,000 records tied to upcoming 2026 travel. BleepingComputer validated one traveler's record and found the exposed data appears far more detailed than MAG initially disclosed, including purchase references, booking status, IP addresses, device data, and full UK postcodes, though no payment card data was found. FulcrumSec claims access came via exposed Iterable API credentials in client-side JavaScript. MAG declined to confirm the specific claims but says around 8.7 million customers were affected overall, making this the largest known data breach at a British airport operator.

## Questions this post answers

### What data did FulcrumSec claim to steal from Manchester Airports Group?

FulcrumSec claimed to have stolen approximately 86 GB of data, including a 21.5 GB Manchester customer export with consolidated profiles combining customer identifiers with booking history and marketing classifications, plus nearly 200,000 records tied to upcoming 2026 travel.

### How did FulcrumSec claim to gain access to Manchester Airports Group's data?

FulcrumSec claims it obtained access using airport-specific Iterable API credentials that were exposed in client-side JavaScript. This allowed the group to allegedly extract consolidated customer profiles and booking records tied to Manchester, London Stansted, and East Midlands airports, though the exact scope of access could not be independently verified.

### How many customers were affected by the Manchester Airports Group data breach?

Around 8.7 million customers were affected, though only email addresses were exposed for the vast majority of them, according to a MAG spokesperson. This makes it the largest known customer data breach affecting a British airport operator, with additional details like vehicle registrations, postcodes, and booking data exposed for a smaller subset.
