A group calling itself FulcrumSec published roughly 550GB of data stolen from Manchester Airports Group after the company refused to pay a ransom, exposing millions of travelers' contact details, booking records, and vehicle plates — after finding admin keys sitting in plain sight in the airports' own website code.

Manchester Airports Group (MAG), the UK's largest airport operator, confirmed it was investigating a cybersecurity incident on August 27, 2026. Six days later, on September 2, a threat group calling itself FulcrumSec published roughly 550GB of data it said it had stolen from MAG, after the company declined to pay a ransom demand. The leak affects an estimated 8.8 million people who had used services at Manchester, London Stansted, or East Midlands airports — the three airports MAG owns and operates.
According to FulcrumSec's own claims, the group didn't need to breach any firewall or exploit a software vulnerability to get started. It says it found live administrator API keys for Iterable, a third-party customer engagement and email marketing platform MAG uses, sitting directly inside the public, unminified frontend JavaScript served on the root domains of all three airport websites. In the group's own words, posted alongside the leaked data: any of the millions of visitors to the sites could have right-clicked "inspect" in their browser and seen the keys themselves, without needing to search subdomains or run any specialized scanning tools.
If accurate, that means the initial access point wasn't a sophisticated exploit at all — it was a basic secrets-management failure: a live, working credential checked into code that ships to every visitor's browser by design.
FulcrumSec's published dataset, which it describes as "pure PII," breaks down to roughly:
MAG has confirmed the breach and confirmed that data was held in a third-party database, but has not published its own detailed breakdown of exactly what was exposed, and has said core airport operations — flights, security, and boarding — were not affected at any point.
FulcrumSec has made several additional claims that go beyond what MAG has confirmed. The group alleges that some of the future-booking records it obtained belong to politicians, public figures, and military personnel, and that it deleted the most sensitive portions of the stolen data after MAG's ransom refusal, leaving a less damaging (but still enormous) dataset in the public leak. Neither claim has been independently verified, and MAG has not commented on them specifically. Ransomware and extortion groups have a well-documented incentive to exaggerate the sensitivity of what they've stolen in order to pressure a victim into paying, so both claims should be treated as allegations from the attacker rather than confirmed fact until shown otherwise.

Airport operators sit on an unusually rich pile of personal data for a transportation company: not just names and emails, but vehicle plates, home addresses, IP addresses, and — for anyone who used in-terminal Wi-Fi, a lounge, or Fast Track — a timestamped record of exactly when they were physically at a given airport. Combined with future booking data, that's the kind of information that has real physical-safety implications for the people in the highest-risk categories, whether or not FulcrumSec's specific claim about politicians and military staff holds up.
The alleged entry point is also a useful reminder for any organization running customer-engagement or marketing-automation tooling: those platforms are frequently integrated via API keys embedded directly in client-side code for convenience, and a key with write or administrative scope has no business being readable by anyone who loads the page. Scoped, read-only, domain-restricted keys — or better, a server-side proxy that never exposes the credential to the browser at all — are the standard fix, and it's one most organizations only discover they're missing after a breach like this one.
MAG has not announced further remediation steps publicly as of this writing, and the incident remains under investigation.
