L3 should be a *major* account for RSA.
It'd be *incredible* that RSA did not give them more information about what has really been stolen.
Only it's starting to *look* as if RSA were cleaned out, *if* this and the Lockheed attack are linked to the RSA job.
OTOH if you want a paranoid conspiracy theory *somebody* wants to take over RSA and has created enough FUD for their share price to tank, making takeover fairly cheap. On completion RSA "discovers" that the hack was much less serious than thought and Lockheed and L3 discover the intrusion was from another source.
Confidence is returned, the RSA share price returns to normal and the new owners sell out, trousering a few $Bn.*
*Readers are reminded this is a *paranoid* conspiracy theory and in realty Occams razor works pretty well. I'd be looking for a big jump in the fortune of who ever is #2 in the business behind RSA.
