Not really "already" since the attack became known in January, before Covid-19 decimated the industry. Were you suggesting that they were already struggling? They made a profit of over £400M in 2019 so it doesn't sound like things were too bad.
Of course, this news doesn't help them now, but it doesn't seem to me like "poor old EasyJet, down on their luck and now this".
Easyjet have been a main airline within the UK for many many years. They may be struggling because of the current environment but this isn't a small operation who wouldn't have a security team.
