Hello, I've looked around quite thoroughly and perhaps I missed something but I'm not entirely sure on how long an Alert on someone from another legion lasts. Is it 24 hours? 48 hours? Something like that? Does the time an alert differ if you were to raid/hack/disable? Aka do each of those three things have conditions on them?

Thanks in advance for any advice on this.

You lose connection with them (allowing you to hit them) 48 hours after they have performed the action on you.
When you ALERT someone, your legion loses connection with them 48 hours after you have alerted them.

In addition, you can only alert someone to your legion if that person D/R/H or Invaded one of your planets in the last 24 hours.

I thought this was updated to include setting off traps and hitting with offensive artifacts? Am I mis-remembering?

Setting off a trap can't get you alerted, but if you use an offensive artifact on someone you can be alerted.

Thank you, I always figured such information Darth was obvious the amount of time an alert lasted however from last hostile action seemed less obvious and I estimated myself somewhere between 24-48 hours before asking here. Couldn't be 100% sure so better to have asked. Many thanks for all the input to the question Helps other users find something too if they seek the same answers!
