A.	watering hole
B.	trojan horse
C.	worm
D.	rootkit
E.	polymorphic virus
F.	clickjacking
G.	metamorphic virus
H.	bot
I.	spyware

Answer 1

1). Changes its signature with each copy made during replication                                                               : E

2). Completely rewrites itself each time it is replicated, something changing its behavior                            :G

3). Exploits browser and plugin vulnerabilities to download and install malware without the user's             :A

      knowledge, with the user having been specifically targed

4). A website with multiple transparent or opaque layers, tricking the user into clicking on a different         : F

   button than they intended

5). a seemingly useful program that contain harmful code                                                                            : B

Explanation:-

• Watering Hole attack :- In this attack , the attack is performed on the specific user by infection websites that they visit frequetly.
• polymorphic virus and metamorphic virus : polymorphic virus just changes the part of its code while metamorphic virus changes the whole code during replication
• clickjacking : Its a interface attacked in which user are tricked to click on hidden content on the decoy website.
• Trojan horse :- It refers to legitimate code or software that are useful but contain harmful hidden code.
• Worm : They are also a kind of malware but they don't change their signature while replication. They simple copy themselves from one host to another
