A Host is infected by worms that propagates through a vulnerable service; the sign(s) of the presence of the worm include:
When a host is infected by worms that propagate through a vulnerable service, one of the primary signs is established connection attempts targeted at the vulnerable services. Worms usually spread by exploiting vulnerabilities, and these attempts are a clear indication of their presence. Decrease in network usage is incorrect as worms typically increase network activity. System instability or crashes can be a sign, but alone it is not specific to worms. Therefore, the most direct sign is the targeted connection attempts.
Worms typically cause harm to their host networks by consuming bandwidth and overloading web servers. So the answer cant be All the above.
I think that the right answer is all the above. It´s very ambogous
The answer is all of the above.
all of above
I think it's all of the above. Because today's worms can already consume network resources and attack services, and can also cause computer crashes
No, please read a carefully "DECREASE in network usage" A worm INCREASE network usage, so correct answer is C
