A penetration tester has discovered sensitive files on a system. Assuming exfiltration of the files is part of the scope of the test, which of the following is most likely to evade DLP systems?

Encoding the data and pushing through DNS to the tester's controlled server.

Padding the data and uploading the files through an external cloud storage service.

Obfuscating the data and pushing through FTP to the tester's controlled server.

Hashing the data and emailing the files to the tester's company inbox.

Which of the following is the most efficient way to exfiltrate a file containing data that could be sensitive?

Encrypt and send the file over HTTPS.

Use steganography and send the file over FTP.

Compress the file and send it using TFTP.

Split the file in tiny pieces and send it over dnscat.

Encrypt and send the file over HTTPS.

The goal is to modify the following script to provide more comprehensive system information:#!/bin/bashps aux >> linux_enum.txtWhich of the following lines would provide the most comprehensive enumeration of the system?

cat /etc/passwd >> linux_enum.txt; netstat -tuln >> linux_enum.txt; cat /etc/bash.bashrc >> linux_enum.txt

whoami >> linux_enum.txt; uname -a >> linux_enum.txt; ifconfig >> linux_enum.txt

hostname >> linux_enum.txt; echo $USER >> linux_enum.txt; curl ifconfig.me >> linux_enum.txt

lsof -i >> linux_enum.txt; uname -a >> linux_enum.txt; ls /home/ >> linux_enum.txt

A company hires a penetration tester to perform an external attack surface review as part of a security engagement. The company informs the tester that the main company domain to investigate is comptia.org. Which of the following should the tester do to accomplish the assessment objective?

Perform information-gathering techniques to review internet-facing assets for the company.

Perform a phishing assessment to try to gain access to more resources and users' computers.

Perform a physical security review to identify vulnerabilities that could affect the company.

Perform a vulnerability assessment over the main domain address provided by the client.

[Attacks and Exploits]A penetration tester finishes an initial discovery scan for hosts on a /24 customer subnet.
