NEW QUESTION # 70
An investigator is analyzing an attack in which malicious files were loaded on the network and were undetected. Several of the images received during the attack include repetitive patterns. Which anti-forensic technique was used?

A. steganography
B. spoofing
C. tunneling
D. obfuscation

Answer: A

Explanation:
The use of repetitive patterns in images is a known indicator of steganography, which is an anti-forensics technique used to hide malicious code or files inside seemingly benign content such as image or audio files.
The repetitive patterns suggest that the image may contain embedded hidden data. This technique is particularly difficult to detect through conventional scanning or antivirus software.
According to theCyberOps Technologies (CBRFIR) 300-215 study guide, steganography is defined as
"concealing malicious content or instructions within ordinary files such as .jpg, .png, or audio files, allowing the content to bypass security filters and reach the target system without detection".

NEW QUESTION # 72
Refer to the exhibit.

According to the Wireshark output, what are two indicators of compromise for detecting an Emotet malware download? (Choose two.)

A. Content-Type: application/octet-stream
B. Hash value: 5f31ab113af08=1597090577
C. filename= "Fy.exe"
D. Domain name: iraniansk.com
E. Server: nginx

Answer: C,D

Explanation:
From the Wireshark capture:
* A (iraniansk.com): This domain is not a known legitimate resource and is hosting a suspicious file named "Fy.exe," strongly indicative of a malware distribution domain.
* D (Fy.exe): The Content-Disposition: attachment; filename="Fy.exe" header explicitly signals a binary executable download, a key indicator in Emotet campaigns.
While Content-Type: application/octet-stream (E) is typical of binary data transfers, it is not unique to malware and cannot by itself serve as a strong IoC. The nginx server (B) and cookie/hash string (C) similarly do not uniquely indicate compromise.

NEW QUESTION # 73
Refer to the exhibit.

A security analyst is reviewing alerts from the SIEM system that was just implemented and notices a possible indication of an attack because the SSHD system just went live and there should be nobody using it. Which action should the analyst take to respond to the alert?

A. Investigate the alert by checking SSH logs and correlating with other relevant data in SIEM.
B. Ignore the alert and continue monitoring for further activity because the system was just implemented.
C. Immediately block the IP address 192.168.1.100 from accessing the SSHD environment.
D. Reset the admin password in SSHD to prevent unauthorized access to the system at scale.

Answer: A

Explanation:
The log entry shows a failed SSH login attempt for an invalid user "admin" from IP192.168.1.100. As the system has just gone live and no legitimate use is expected, this could be an early reconnaissance or brute- force attempt. However, blocking IPs or resetting passwords without fully understanding the context could lead to incomplete remediation or false positives.
According to Cisco CyberOps best practices, the first step is to thoroughly investigate the alert by correlating it with other logs (e.g., authentication logs, IDS/IPS logs) to determine the intent and scope of activity.

NEW QUESTION # 76
Refer to the exhibit.

Which two determinations should be made about the attack from the Apache access logs? (Choose two.)

A. The attacker uploaded the WordPress file manager trojan.
B. The attacker used r57 exploit to elevate their privilege.
C. The attacker used the WordPress file manager plugin to upload r57.php.
D. The attacker logged on normally to WordPress admin page.
E. The attacker performed a brute force attack against WordPress and used SQL injection against the backend database.

Answer: A,C

Explanation:
The Apache access logs in the exhibit show a sequence of HTTP requests and responses indicative of a malicious upload via WordPress:
* A POST to:
* /wp-admin/admin-ajax.php with parameters that include uploading r57.php (a known PHP web shell).
* The uploaded file name appears as r57.php in:# &name=%5B%5D=r57.php&FILES...
* There are plugin installation and activation attempts, specifically for:
* file-manager plugin:# plugin=file-manager&...
* Which is known to be vulnerable and exploited for file uploads.
* GET requests to:
* /wp-content/57.php and variations such as 57.php?28 - This suggests that r57.php was successfully uploaded and is being accessed.
These logs reveal that:
* D. The attacker used the WordPress file manager plugin to upload r57.php - confirmed by plugin activity and file uploads.
* B. The attacker uploaded the WordPress file manager trojan - as evidenced by the direct access to /wp- content/57.php (r57 shell variant).
Other options are invalid or speculative:
* A is correct in identifying r57 as a web shell, but the logs don't show privilege escalation.
* C mentions brute force and SQL injection, which are not indicated here.
* E assumes legitimate access - logs suggest exploitation, not standard login.

NEW QUESTION # 77

Refer to the exhibit. A network administrator creates an Apache log parser by using Python. What needs to be added in the box where the code is missing to accomplish the requirement?

A. r'*\b'
B. r'\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}'
C. r'\d(1,3),\d(1.3),\d{13}.df{1,3}'
D. r''\b{1-9}[0-9}\b'

Answer: B

Explanation:
The goal of the given Python code is to parse an Apache access log and extract IP addresses using regular expressions (regex). In this context, the most appropriate regex pattern to extract IPv4 addresses from log data is:
* r'\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}'
This pattern matches typical IPv4 addresses, where each octet consists of 1 to 3 digits separated by periods.
For example, it matches addresses like 192.168.1.1 or 10.0.0.123. The pattern uses:
* \d{1,3} to capture between 1 and 3 digits,
* \. to match the dot (escaped since . is a special character in regex),
* repeated 4 times with proper separation to form the full IPv4 structure.
Options A, B, and C either include incorrect syntax, improper escape sequences, or do not represent a valid IP address pattern.
This type of log analysis and pattern extraction is described in the Cisco CyberOps Associate curriculum under basic scripting and automation techniques used in log and artifact analysis.
Reference: CyberOps Technologies (CBRFIR) 300-215 study guide, Section: "Basic Python Scripting for Security Analysts" and "Log Analysis and Data Extraction using Regex."

NEW QUESTION # 78
Refer to the exhibit.

Which type of code is being used?

A. BASH
B. Python
C. VBScript
D. Shell

Answer: B

Explanation:
The code in the exhibit is written in Python. Here's how we can confirm:
* The function definition uses Python syntax: def function_name(args):
* It uses the b64encode and decode functions - typical of Python's base64 module.
* Data structures such as dictionaries are used with curly braces (e.g., form_data = {entry1: enc1, ...}).
* The conditional syntax uses "if r.status_code == 200:" which is Pythonic.
* The request object "r = post(...)" and use of headers show standard use of the Python requests library.
This type of script is typical in exfiltration scenarios where encoded information is sent via a web form (in this case Google Forms), bypassing detection systems.
Reference:CyberOps Technologies (CBRFIR) 300-215 study guide, Chapter on "Working with Malware and Exploit Scripts," which includes analysis of obfuscated and encoded scripts written in Python used for data exfiltration or C2 communication.

NEW QUESTION # 80
Refer to the exhibit.

According to the SNORT alert, what is the attacker performing?

A. XSS attack against the target webserver
B. brute-force attack against the web application user accounts
C. SQL injection attack against the target webserver
D. brute-force attack against directories and files on the target webserver

Answer: D

NEW QUESTION # 81
Refer to the exhibit.

What is occurring?

A. The threat actor creates persistence by creating a repeatable task.
B. Obfuscated scripts are getting executed on the victim machine.
C. RDP is used to move laterally to systems within the victim environment.
D. Malware is modifying the registry keys.

Answer: A

Explanation:
The command in the image uses schtasks /create with the ONLOGON schedule and System user context to execute test.exe. This is a well-documented persistence technique, where an attacker ensures that a malicious executable is launched automatically at each system logon. This kind of scheduled task creation aligns with persistence techniques in the MITRE ATT&CK framework (T1053).

NEW QUESTION # 82
Refer to the exhibit.

Which two actions should be taken based on the intelligence information? (Choose two.)

A. Route traffic from identified domains to block hole.
B. Block network access to identified domains.
C. Block network access to all .shop domains
D. Use the DNS server to block hole all .shop requests.
E. Add a SIEM rule to alert on connections to identified domains.

Answer: B,E

Explanation:
The STIX intelligence feed in the exhibit identifies specific malicious domains, such as:
* fightcovid19.shop
* nocovid19.shop
* stopcovid19.shop
These are categorized as "Malicious FQDN Indicator." The recommended cybersecurity actions when such threat intelligence is received are:
* D. Block network access to identified domains: This directly prevents users or systems from communicating with known malicious infrastructure and is a critical first step in threat mitigation.
* B. Add a SIEM rule to alert on connections to identified domains: This ensures that any attempted communication with these domains is flagged for immediate review and action, enabling real-time threat detection and incident response.
Blocking all .shop domains (Option A or C) would be overbroad and potentially disruptive, as many legitimate websites also use that TLD. Option E (routing to block hole) could be valid as a DNS strategy, but B and D represent the most actionable and precise responses per standard incident response practices.
Reference: CyberOps Technologies (CBRFIR) 300-215 study guide, Chapter on "Threat Intelligence Platforms," covering how to operationalize STIX/TAXII indicators via blocking and SIEM integration.

NEW QUESTION # 83

A. shell
B. Python
C. Bash
D. VBScript

Answer: B

Explanation:
The code includes syntax and modules such as import win32con, import win32api, and uses Python-specific formatting like def, try/except, and print, clearly indicating that this is written in Python. It also uses the wmi module to monitor process creation events-a common technique in Python-based process monitoring scripts on Windows.

NEW QUESTION # 84
Refer to the exhibit.

An engineer is analyzing a TCP stream in a Wireshark after a suspicious email with a URL. What should be determined about the SMB traffic from this stream?

A. It is sharing access to files and printers.
B. It is redirecting to a malicious phishing website,
C. It is exploiting redirect vulnerability
D. It is requesting authentication on the user site.

Answer: C

NEW QUESTION # 85

A. Generate a Windows executable file.
B. Open the Mozilla Firefox browser.
C. Initiate a connection to 23.1.4.14 over port 8443.
D. Validate the SSL certificate for 23.1.4.14.

Answer: C

Explanation:
This Python script uses a combination of libraries (urllib, zlib, base64, and ssl) to:
* Disable SSL certificate verification (ssl.CERT_NONE and check_hostname=False).
* Construct a custom HTTPS opener with the specified SSL context.
* Add a forged User-Agent header to mimic Internet Explorer 11.
* Connect to the URL https://23.1.4.14:8443.
* Download and execute base64-encoded and zlib-compressed content from that URL using:
exec(zlib.decompress(base64.b64decode(...).read()))
This shows a classic example of:
* Downloading payloads from a remote server (23.1.4.14:8443).
* Avoiding detection by disabling SSL verification.
* Executing the payload dynamically with exec() after decoding and decompressing.
The main goal is clearly to initiate a connection to a remote command-and-control (C2) server on port 8443 and download/execute additional code.
Hence, the correct answer is: A. Initiate a connection to 23.1.4.14 over port 8443.

NEW QUESTION # 86
A company had a recent data leak incident. A security engineer investigating the incident discovered that a malicious link was accessed by multiple employees. Further investigation revealed targeted phishing attack attempts on macOS systems, which led to backdoor installations and data compromise. Which two security solutions should a security engineer recommend to mitigate similar attacks in the future? (Choose two.)

A. secure email gateway
B. endpoint detection and response
C. web application firewall
D. intrusion prevention system
E. data loss prevention

Answer: A,B

Explanation:
Comprehensive and Detailed Explanation:
* Endpoint Detection and Response (EDR) tools provide behavioral analytics and continuous monitoring to detect malware such as backdoors, which is especially critical on endpoints like macOS devices.
These tools are essential to detect post-compromise activities and contain threats before they spread.
* Secure Email Gateway (e.g., Cisco ESA) plays a key role in blocking phishing emails-the initial vector in this attack. It uses filters and reputation analysis to prevent malicious links or attachments from reaching end users.
Incorrect Options:
* C. DLP focuses on preventing data exfiltration, not phishing prevention or backdoor detection.
* D. IPS is effective for known signature-based threats but less effective against phishing links and endpoint-level backdoors.
* E. WAF protects web servers, not end-user devices from phishing or backdoor infections.
Therefore, the correct answers are: A and B.
