-Uses lightweight shellcode
-Uses low observable characteristic attacks - answer✔A fileless malicious software can replicate
between processes in memory on a local host or over network shares. What other behaviors and
techniques would classify malware as fileless rather than a normal virus? (Select all that apply.)
-Computer Bots,
-Command & Control - answer✔An attacker is planning to set up a backdoor that will infect a
set of specific computers at an organization, to inflict a set of other intrusion attacks remotely.
Which of the following will support the attackers' plan? (Select all that apply.)
-Launch a Distributed Denial of Service (DDoS) attack

PC. What type of Trojan malware is this?

program. - answer✔How can the lack of logic statement tests on memory location variables be
detrimental to software in development?
A buffer overflow - answer✔An attacker gained remote access to a user's computer by exploiting

Race condition - answer✔Developers found a "time of check to time of use" (TOCTTOU)

created within the app before the app uses the data later. This vulnerability is taking advantage of
what process in the application?
Revealing database server configuration - answer✔A web application's code prevents the output
of any type of information when an error occurs during a request. The development team cited
