In June 2026, the sports and entertainment company Madison Square Garden Sports was the target of a ShinyHunters "pay or leak" extortion campaign. The group later published the alleged data, which included almost 10M unique email addresses spanning staff and customers, along with extensive personal, employment and customer relationship information.

What leaked

Phone number

Used for calls and texts that open already knowing who you are.

Fake adviser calls →
Postal address

Used to stage a delivery, a utility visit or a neighbour that never happened.

Social engineering →
Email address

The address every one of these scams will arrive at.

Phishing →
Name

Used to make a cold approach look like a conversation already under way.

Social engineering →
Support history

Past exchanges with the company, so a fake agent picks up exactly where a real one left off.

What is not listed

Passwords
Bank details
Card numbers

So there is no password to change here — the usual first move does not apply.

The record shows what was found in the data. Not listed is not the same as proven untouched.
