Suggest replacing this sentence, which feels kind of dismissive to me:

Sometimes, that science is specifically targeted by attackers who are interested in doing nothing more than causing a little mayhem on the side.

with:

Sometimes, that science is specifically targeted by attackers whose goal is disruption, possibly for political reasons or even simple mischief-making.

and this sentence:

Finally, there may well be times when computing systems related to science projects are the innocent bystanders who are nonetheless the victims of "malware" that is simply ever-present on the Internet.

with:

Finally, computing systems related to science projects can suffer a disruptive security incident without being specifically targeted by an attacker at all, simply by being present on a network, and exploitable.
