Question

A. Adware
B. Ransomware
C. Identity Theft
D. Dropper

Answer 1

Answer:

to access networks that have good perimeter control. Bots rarely announce their presence with high scan rates that damage network infrastructure; instead, they infect networks in a way that escapes immediate notice.

Advanced botnets may take advantage of common internet of things (IOT) devices such as home electronics or appliances to increase automated attacks. Crypto mining is a common use of these bots for nefarious purposes.

Distribution Channels for Malware

Advanced malware typically comes via the following distribution channels to a computer or network:

Drive-by download—Unintended download of computer software from the Internet

Unsolicited email —Unwanted attachments or embedded links in electronic mail

Physical media—Integrated or removable media such as USB drives

Self propagation—Ability of malware to move itself from computer to computer or network to network, thus spreading on its own
