Cisco Conducting Forensic Analysis & Incident Response Using Cisco Technologies for CyberOps Sample Questions (Q48-Q53):

NEW QUESTION # 48
Refer to the exhibit.

What is the IOC threat and URL in this STIX JSON snippet?

A. malware;
'http://x4z9arb.cn/4712/'
B. stix;
'http://x4z9arb.cn/4712/'
C. malware; x4z9arb backdoor
D. x4z9arb backdoor;http://x4z9arb.cn/4712/
E. malware; malware--162d917e-766f-4611-b5d6-652791454fca

Answer: A

Explanation:
This STIX (Structured Threat Information eXpression) JSON snippet provides two key elements relevant for IOC (Indicator of Compromise) analysis:
* The indicator pattern shows a suspicious URL:#
"pattern": "[url:value = 'http://x4z9rb.cn/4712/']"
This is the actual IOC that can be used for detection.
* The type of object that the indicator relates to:# "type": "malware"# "name": "x4z9arb backdoor"This indicates the nature of the threat associated with the IOC is malware.
Therefore,
the threat is "malware" and the associated indicator (IOC) is the URL: http://x4z9rb.cn/4712/ Option A correctly captures both the IOC category ("malware") and the indicator value ("http://x4z9rb.cn/4712/").
Reference:CyberOps Technologies (CBRFIR) 300-215 study guide, Chapter on "Understanding Threat Intelligence Platforms," including the use of STIX/TAXII for representing threat data.

NEW QUESTION # 49
Refer to the exhibit.

Which two actions should be taken as a result of this information? (Choose two.)

A. Update the AV to block any file with hash "cf2b3ad32a8a4cfb05e9dfc45875bd70".
B. Block all emails with subject containing "cf2b3ad32a8a4cfb05e9dfc45875bd70".
C. Block all emails sent from an @state.gov address.
D. Block emails sent from Admin@state.net with an attached pdf file with md5 hash
"cf2b3ad32a8a4cfb05e9dfc45875bd70".
E. Block all emails with pdf attachments.

Answer: A,D

Explanation:
The XML (STIX/CybOX format) details anemail-based threatindicator. Specifically:
* Theemail addresscontains "@state.gov" (not exact match, so blocking all @state.gov would be overbroad).
* Theattachment is a PDFfile with a specifiedMD5 hash: cf2b3ad32a8a4cfb05e9dfc45875bd70.
* Theattachment sizeis 87022 bytes.
From a threat mitigation perspective:
* Ais correct: Updating AV to block or flag files matching the malicious hash is a standard response.
* Dis correct: The email address context and hash together provide a precise rule for blocking-this prevents false positives.
Incorrect options:
* Boverreaches by blocking an entire domain without confirming threat context.
* Cwould stop all PDFs, which is impractical.
* Eis incorrect; there is no indication that the hash appears in the subject line.

NEW QUESTION # 50
Refer to the exhibit.

A web hosting company analyst is analyzing the latest traffic because there was a 20% spike in server CPU usage recently. After correlating the logs, the problem seems to be related to the bad actor activities. Which attack vector is used and what mitigation can the analyst suggest?

A. SQL Injection; implement input validation and use parameterized queries.
B. Phishing attack; conduct regular user training and use email filtering solutions.
C. Distributed denial of service; use rate limiting and DDoS protection services.
D. Brute-force attack; implement account lockout policies and roll out MFA.

Answer: D

Explanation:
Comprehensive and Detailed Explanation:
The log entries show repeated SSH login attempts for various invalid usernames (e.g., admin, phoenix, rainbow, test, user, etc.) from different source ports. These are clear signs of a brute-force attack-an automated process trying multiple usernames and passwords in hopes of gaining access.
Mitigating such attacks includes:
* Implementing account lockout policies (e.g., locking an account after several failed login attempts).
* Enabling Multi-Factor Authentication (MFA) to ensure that password guessing alone is insufficient for account access.
Therefore, the correct answer is:
D). Brute-force attack; implement account lockout policies and roll out MFA.
