"This action can be used on any large amount of data, such as a list of icons in a node" - SR4A, page 230, Data Search action. You might use your Analyze program instead of Browse, but that's the action. Know how's about you actually list your issues?
That gives you a list of icons in a node, that doesn't tell you which icon is which. It is explicit that you need to take a simple action to determine whether one icon is a Program, a Persona, a Sprite, an Arrow, or even Colonel Sanders's Secret Recipe.
And let's not forget the Denial of Service rules. You don't even need to succeed, as even failing to hack will make alerts, and a node will just plain shut down with too many alerts. If your goal is for a node to not even be on, which would be very handy in many cases, there's not really much they can do.
EDIT: At best, assuming you used that incorrect reading, it's still an entire Initiative Pass to find/identify ONE icon; presuming all icons are in near plain-view (Threshold 2). If you somehow care about more than one icon, which you very well should, things are going to get hairy very quick; "did I remember to search for a third Black Hamm...ow"
