Cisco Conducting Forensic Analysis & Incident Response Using Cisco Technologies for CyberOps Sample Questions (Q164-Q169):

NEW QUESTION # 164
Which tool is used for reverse engineering malware?

Answer: D

Explanation:
Ghidrais a free and open-source software reverse engineering (SRE) suite developed by the NSA. It includes disassembly, decompilation, and debugging tools specifically designed for analyzing malware and other compiled programs.
The Cisco CyberOps guide referencesGhidraas a top tool for reverse engineering binary files during malware analysis tasks, making it ideal for understanding malicious code behavior at a deeper level.


NEW QUESTION # 165
Refer to the exhibit.

Which type of code created the snippet?

Answer: C

Explanation:
The syntax in the code snippet includes:
On Error Resume Next - a classic VBScript error-handling directive.
function ... end function structure.
Use of Mid(), Chr(), and Asc() functions - all commonly used in VBScript for string manipulation.
CInt() for conversion - typical in VBScript.
These characteristics align exactly with VBScript, which is frequently used in malicious macros and obfuscated payloads for malware distribution, as covered in the Cisco CyberOps Associate curriculum when analyzing scripts and encoded threats.


NEW QUESTION # 166
Refer to the exhibit.

What should an engineer determine from this Wireshark capture of suspicious network traffic?

Answer: D

Explanation:
In the provided Wireshark capture, we see multiple TCP SYN packets being sent from different source IP addresses to the same destination IP address (192.168.1.159:80) within a short time window. These SYN packets do not show a corresponding SYN-ACK or ACK response, indicating that these TCP connection requests are not being completed.
This pattern is indicative of a SYN flood attack, a type of Denial of Service (DoS) attack. In this attack, a malicious actor floods the target system with a high volume of TCP SYN requests, leaving the target ' s TCP connection queue (backlog) filled with half-open connections. This can exhaust system resources, causing legitimate connection requests to be denied or delayed.
The countermeasure for this scenario, as highlighted in the CyberOps Technologies (CBRFIR) 300-215 study guide under Network-Based Attacks and TCP SYN Flood Attacks, involves:
Increasing the backlog queue: This allows the server to hold more half-open connections.
Recycling the oldest half-open connections: This ensures that legitimate connections have a chance to be established if the backlog fills up.
Reference: CyberOps Technologies (CBRFIR) 300-215 study guide, Chapter 5: Identifying Attack Methods, SYN Flood Attack section, page 146-148.


NEW QUESTION # 167
An organization recovered from a recent ransomware outbreak that resulted in significant business damage.
Leadership requested a report that identifies the problems that triggered the incident and the security team's approach to address these problems to prevent a reoccurrence. Which components of the incident should an engineer analyze first for this report?

Answer: A

Explanation:
To prepare a post-incident report, thecauseof the incident (what enabled it) and theeffect(what damage was done) are the primary components analyzed first. This allows teams to understand vulnerabilities exploited and the consequences, forming the basis for corrective action.
The Cisco CyberOps guide recommends beginning withroot cause analysisfollowed by impact assessment to guide future prevention strategies.


NEW QUESTION # 168
An engineer is investigating a ticket from the accounting department in which a user discovered an unexpected application on their workstation. Several alerts are seen from the intrusion detection system of unknown outgoing internet traffic from this workstation. The engineer also notices a degraded processing capability, which complicates the analysis process. Which two actions should the engineer take? (Choose two.)

Answer: D,E

Explanation:
When suspicious activity is detected on a workstation, immediate steps need to be taken to preserve evidence and prevent further compromise:
* Disconnecting the system from the network (C)is crucial to stop potential exfiltration of data or ongoing communications with a command-and-control server. This isolation prevents further spread or damage while preserving the state of the compromised system for further investigation.
* Taking an image of the workstation (E)is part of the forensics acquisition process. It involves creating a bit-by-bit copy of the system's disk, which preserves all evidence in its current state. This allows for thorough forensic analysis without affecting the original evidence.
These steps align with the best practices outlined in the incident response and forensics processes (as described in theCyberOps Technologies (CBRFIR) 300-215 study guide). Specifically, in theIdentification and Containmentphases of the incident response cycle, it's emphasized that isolating the system and preserving evidence through imaging are critical to ensuring both containment of the threat and successful forensic investigation.
Reference:CyberOps Technologies (CBRFIR) 300-215 study guide, Chapter: Understanding the Security Incident Response Process, Identification and Containment Phases, page 102-104.
