Alfredo receives an email at work from what appears to be his bank stating the bank's password policy has changed. The message says he needs to use a stronger password and contains instructions to click on the supplied link to reset it. Which of the following could explain why Alfredo received this email?
Alfredo previously clicked on a malicious payload that sent his email address to a threat actor.
Alfredo is using a weak password, so the bank is being proactive in asking him to change it.
The bank's network has been compromised so they are implementing stricter policies.
The company where Alfredo works is not using a phishing filter.
Which of the following best describes characteristics of DKIM? Select three.
It uses asymmetric cryptography.
It uses symmetric cryptography.
It incorporates elements of SPF.
It encrypts the message body and the headers.
It stores the public key in a record on the sending domain's DNS.
A threat actor successfully breaches the perimeter of an organization and decides to use the Windows Command Shell instead of PowerShell to launch an attack. Considering the Windows Command Shell is more limited in its capabilities, why would the threat actor opt to use it?
Its commands can be launched without starting a new identifiable process.
The Windows Command Shell is easier to breach than PowerShell.
It starts child processes that blend in with normal system processes.
Since the Windows Command Shell is seldom used, it is monitored with less intensity.
A security analyst is researching the behavior of Word documents that contain hidden VBA code that issues calls to execute other files. Which of the following will help the analyst identify a pool of files that meet this criterion?
