I'm surprised this card - at least from my experience - doesn't see play. Cyber Threat is great in any anarch deck attempting to bankrupt the Corp through forced ICE rezzing. For 1, you can give the Corp two pretty bad choices: Rez a piece of ICE without making the runner suffer its effects unprepared or give the runner one free access. This effect is somewhat lessened once you're staring at 2-3+ layers of ICE, but it still allows you to make a run with perfect information about the ICE you'll be facing.

The not-so-great side of Cyber Threat is when you take a shot at HQ and the Corp rezzes a Pop-up Window or similar, you've wasted a credit. This could be mitigated if you're running Reina Roja and/or have a Xanadu out, both likely options if you're going for econ denial/ICE taxing.

Think of this card as saying: "For 1, make a run. If the corp rezzes ice, immediately jack out without encountering that ice." Close enough.

It can be surprisingly useful in ice-destruction decks using the cutlery set (Knifed, Forked, Spooned) and relying on Eater.

The problem it addresses is that getting into a server often looks like this:

1. : Run. Corp rezzes ice. Bounce off or, if dangerous, break with Eater.
2. : Play cutlery. Use Eater to trash ice.
3. : Run again, hopefully collecting your prize.

That's 3 and, potentially 2x the normal s to break.

Playing Cyber Threat on the same server, following the same pattern, costs you 1 and either gives you the access, or saves you the from an Eater break if the ice is dangerous. That can sometimes be the difference between getting in and not.

Ice destruction often requires forcing rezzes (especially post-MWL nerfing of Clone Chip + Parasite), and this is another way to force that to happen.

I'm surprised it's not a Run event. If it were it would be wonderful to play in Adam, and feels like it ought to combo with Public Terminal, Doppelgänger, etc.

It would actually be pretty good in Kit, because it gets around a scary situation for her: double-iced servers with the outer ice rezzed. No way she's spending 3 inf on it though.
