What Is the Joker Malware URL?

There is no single Joker malware URL. Joker is an Android trojan that signs users up for paid SMS subscriptions and collects SMS messages. It spreads through apps published in app stores. After installation, it contacts command-and-control servers on domains that change often. Security vendors publish lists of observed domains, but none of them is "the" Joker URL. A link that claims to be the official Joker URL is a scam, a research sample, or a stale indicator.

Treat any URL that promises a Joker sample or payload as hostile. The practical task is not to find a URL. The task is to check whether your device or accounts were exposed, remove the app, and report the fraud.

What the Indicators Do and Do Not Tell You

Threat-intelligence feeds list Joker command-and-control domains, not one URL. Those domains expire and get replaced. Blocking a single domain does not remove the app. Removal and a carrier dispute are the steps that stop the charge.
