OSN Hack

Back in March 2025, the Oregon Surveillance Network, an organization that shares information about card counters to other casinos, was hacked by a group called Arkada which hacked numerous organizations in Oregon. 1 year later, about 2 weeks ago, the alias Brillaint-Bug-4748 on Reddit, a 3rd party not affiliated with the hackers, somehow got ahold of this information and created a free OSN search tool, so that card counters/advantage players can find out what OSN and the casinos knows about them.

The website is blackjack.tools

Me personally, I found my information in OSN as well, and matched it up with my records.

Any thoughts?

I'm immediately curious if the search is of live data, or a copy. Live access would seem to be temporary, until they figure it out and close the door. Copied data would seem to be persistent, but increasingly stale as time goes by.
