This is a non safe for work, as in lewd, instance.
It’s safe to assume that anything you see here will be lewd.
Just letting you know. If you view the content and then pull a surprised pikachu when you see big anime tiddies, Judy Hopps getting railed or some furry vore… Then it’s on you.
Should this popup continue to show up, you may want to enable cookies or disable privacy focused addons on your browser, I assure you we won’t track our user.
Should that fail, some users claim they got rid of it by hammering the ok button.
No, why would it? It will run code in the context of the current user which is absolutely enough to start a new process that will run in the background, download more code from a attacker server and allow remote access. The attacker will only have as much permissions as the user executing the code but that is enough to steal their files, run a keyloggers, steal their sessions for other websites etc.
They can try to escalate to the admin user, but when targeting private victims, all the data that is worth stealing is available to the user and does not require admin privs.
