"Back in his cube again, Frank powered up his computer and reflected on what he’d just learned, which was both not much and a lot. Not much, in that he still had no idea who was behind the attack, or what he was trying to accomplish. But a lot because the only people targeted besides himself were George and Rick, and because only the files in one directory had been affected. That meant that what had hit the Library of Congress was no virus unleashed against Web sites generally, bent on spreading random mayhem. Instead, it was obviously an attack targeted just at the LOC. And once it had made its way through the LOC firewall, the attack had been manually controlled rather than automated.
"It also appeared that whoever was behind the exploit knew exactly what he was looking for, and had figured out where to find it. That suggested the cracker had managed to acquire some degree of inside knowledge, or at least that he had been willing and able to spend a lot of time roaming around inside the firewall figuring out what might be of interest to him. Frank hoped it was the latter, since the former meant that an employee was either directly behind the attack, or had leaked information to whoever was."
