Free streams of the big game or the new release are bait for malware and credential theft.
The scam
Unofficial streaming sites and "free premium" apps demand a login, a card to "verify age", or a browser extension to play. The content may even work — while the extension reads everything you type, or the stolen login is tried against your bank.
How to stay safe
Stream from official sources
Use the services you pay for, from their own apps. If a stream asks for a card or an install, close it.
Use unique logins
Never reuse an email password on a streaming or entertainment site — a breach there should not open anything else.
Organized criminals and pick-pockets frequently target high-net-worth individuals, stealing their mobile phones for immediate access to valuable digital accounts.
