Free Practice Questions for Cisco 300-215 Exam

Process Explorer is an advanced Windows-based utility that shows real-time data about running processes, CPU usage, services, DLLs, and handles. It is specifically designed for this kind of investigation and is part of the Sysinternals Suite.

The scenario describes an attack vector where insiders or malicious actors use removable media (USB drives) to introduce malware, which then connects to external sources to exfiltrate data and compromise systems.

Option B addresses the human factor and technological prevention. The guide stresses the need for training to ensure users are aware of social engineering and removable media risks. Blocking the use of USB drives at a system level further minimizes attack vectors.

Option E, using Multi-Factor Authentication (MFA), provides an additional layer of defense. Even if credentials are stolen, MFA can prevent the attacker from accessing sensitive internal resources without the second authentication factor.

These controls align with defense-in-depth strategies recommended in the Cisco CyberOps Associate curriculum to combat insider threats and external unauthorized access.

Comprehensive and Detailed Explanation:

The log entry contains the following key elements:

The timestamp: (04/Jan/2022:20:18:06 +0000)

HTTP method and URI: "GET /%60%60%60%60%60%60/ HTTP/2.0"

HTTP status code: 404

User-Agent: Mozilla/5.0 ... Firefox/95.0

The status code 404 indicates that the requested resource was not found on the server. This is a standard HTTP response that signifies the server could not locate the requested URI (in this case, likely due to a malformed or invalid path /\`````/, where %60 is the URL-encoded form of the backtick character "").

There is no clear evidence of SQL injection, WAF detection, or redirection in this log. The use of encoded backticks may suggest probing behavior, but the log does not show a definitive attack signature.

Therefore, the correct interpretation is:

Answer: D. The requested page was not found.

Once an incident has occurred, the appropriate course of action is to engage the organization's Incident Response (IR) plan. This is a structured approach to contain, analyze, and eradicate threats before they spread across the network.

The Cisco CyberOps Associate study guide emphasizes:

“Incident response and handling are essential within an organization… The main objective of implementing an incident handling process is to reduce the impact of a cyber-attack, ensure the damages caused are assessed, and implement recovery procedures”.

In particular, the containment phase of IR is focused on isolating the threat and preventing lateral movement or further compromise.

Options such as "root cause" or "attack surface" are relevant at later stages of analysis and mitigation, not immediate containment. Therefore, the correct answer is C.

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.

The Python code snippet:

Uses socket.socket(AF_INET, SOCK_STREAM), which indicates TCP communication

Connects to a remote server (192.168.1.10 on port 80)

Sends a manual HTTP GET request

Receives the response using s.recv()

This is a classic example of TCP/IP socket programming, specifically creating a simple TCP client to communicate with a web server. It does not monitor traffic or crawl websites — it sends a crafted request and prints the response.

Thus, this code best fits:

D. socket programming listener for TCP/IP communication.

Fileless malware resides in memory and does not leave traditional file artifacts, making it difficult for antivirus solutions to detect. The most effective next step is to isolate the endpoints to prevent lateral movement and perform memory forensics to capture volatile data and identify any running malicious processes.

The provided log file contains multiple HTTP GET requests attempting to access various directories and files on the web server such as:

/balance

/security

/finance

/secret

/opt

/fuzzer/admin

These requests appear to be sequential, systematically targeting commonly used file and directory paths. The response codes are mostly 404 (Not Found) and a few 301s, indicating that the requester is trying different permutations of paths to discover hidden or vulnerable endpoints. This behavior is consistent with directory fuzzing, a reconnaissance technique used by attackers (or automated tools) to map out web directory structures by sending a high volume of crafted requests to guess hidden or unlinked directories and files.

This is distinct from DDoS (which would manifest as volume-based access issues), SQL injection (which targets specific parameters within requests), or botnet infection (which generally involves command-and-control communication or massive traffic floods).

Comprehensive and Detailed Explanation:

The exhibit lists several behaviors under categories such as Remote Access, Stealer/Phishing, Persistence, and Evasive Marks. Notably, under “Persistence” it states:

“Writes data to a remote process”

This behavior is indicative of “process injection,” a technique where malware writes or injects malicious code into the address space of another process. This allows the malware to evade detection and run within the context of a legitimate process.

This matches the MITRE ATT&CK technique T1055 (Process Injection), which is also discussed in the Cisco CyberOps Associate guide under evasion and persistence tactics used by malware.

While modified registry and data compression are possible signs of malware, they are not explicitly referenced in the exhibit. The definitive indicator shown is related to process injection.

Therefore, the correct answer is: C. process injection.
