Bad actors are abusing large, open-registration, low-moderation Mastodon instances in order to provide direction to the Vidar Stealer trojan horse, which steals passwords, credit card details, bitcoin wallets, etc.

If you run a large, open-registration, low-moderation instance, please consider changing at least one of those qualities.

@noelle I'm guessing as it's a trojan it's still dependent on the victim actively following the IP?

Or does it somehow execute on its own? :blobtilt:

@Jo The example I've seen for this trojan is as a wrapper for an otherwise-valid VPN software; the trojan installs the VPN but also installs itself in the process, so it can run in the background.
