NEW QUESTION # 55
What is a recommended mitigation strategy to block Command and Control (C2) traffic?
Answer: C
NEW QUESTION # 56
What is the significance of gaining visibility into the network as part of threat hunting?
Answer: A
NEW QUESTION # 57
Refer to the exhibit.
A security team detects a spike in traffic from the company web server. After further investigation, the team discovered that multiple connections have been established from the server to different IP addresses, but the web server logs contain both expected traffic and DDoS traffic. Which attribute must the team use to further filter the logs?
Answer: C
Explanation:
The correct answer isConnection status. In this scenario, the key challenge for the security team is differentiatinglegitimate outbound trafficfrommalicious or DDoS-related trafficoriginating from the same web server. Since both types of traffic coexist in the logs, analysts must rely on an attribute that meaningfully distinguishes normal behavior from abnormal patterns.
The exhibit shows numerous TCP connections from the web server to many different external IP addresses, with varyingTCP statessuch as ESTABLISHED, TIME_WAIT, and FIN_WAIT. These connection states are highly valuable for threat hunting and network analysis. During DDoS activity-especially reflected or amplification-style attacks, or when a server is abused as part of an attack-connections often remain half- open, rapidly transition to TIME_WAIT, or fail to fully establish. In contrast, legitimate web traffic typically results in stable, short-lived ESTABLISHED sessions that follow predictable patterns.
Option B (destination port) is not useful here because most web traffic-both legitimate and malicious- commonly uses ports 80 or 443. Option C (IP address of the web server) provides no filtering value because all traffic already originates from that server. Option D (protocol) is also ineffective, as both normal and DDoS traffic in this case use TCP.
From a professional SOC and threat hunting standpoint,connection state analysisis a foundational technique for detecting volumetric attacks, beaconing behavior, and abnormal session churn. By filtering logs based on connection status, analysts can quickly isolate suspicious patterns such as excessive short-lived connections, abnormal teardown behavior, or asymmetric session states that are characteristic of DDoS-related activity.
This approach aligns with mature threat hunting practices:when indicators overlap, pivot to behavioral attributes. Connection status provides the necessary behavioral signal to separate expected traffic from attack traffic and supports faster, more accurate incident response.
NEW QUESTION # 58
A SOC team wants to detect lateral movement performed using legitimate administrative tools rather than malware. Which telemetry source provides the MOST reliable visibility for this hunting objective?
Answer: B
Explanation:
The correct answer isauthentication and remote execution logs. Lateral movement using legitimate tools relies heavily oncredential use and remote management protocols, not malware execution.
Attackers commonly use:
* RDP
* SMB administrative shares
* WinRM
* WMI
* SSH
These techniques generateauthentication events, remote logons, and service execution logsrather than malware alerts. Antivirus tools are ineffective here because no malicious binaries are involved.
Option A is ineffective against living-off-the-land attacks. Option B is unrelated to lateral movement. Option D may show some activity but lacks the necessary depth to identify privilege misuse or session hopping.
Authentication telemetry enables hunters to detect anomalies such as:
* Logons between non-associated systems
* Sudden administrative access
* Credential reuse across hosts
* Abnormal session timing and frequency
This data is foundational forcredential-based attack detection, which remains one of the most common breach paths today. It also aligns withMITRE ATT&CK Lateral Movement and Credential Access tactics.
Thus, optionCis the correct answer.
NEW QUESTION # 59
The security team detects an alert regarding a potentially malicious file namedFinancial_Data_526280622.pdf downloaded by a user. Upon reviewing SIEM logs and Cisco Secure Endpoint, the team confirms that the file was obtained from an untrusted website. The hash analysis of the file returns an unknown status. Which action must be done next?
Answer: D
Explanation:
The correct next action is tosubmit the file for sandboxing. In professional security operations and threat hunting workflows, sandboxing is the most appropriate step when a file originates from an untrusted source and hash-based reputation checks return anunknownresult. An unknown hash means the file has not yet been classified as benign or malicious by threat intelligence databases, which is common with newly created malware or targeted attacks.
Sandboxing allows the security team to performdynamic analysisby executing the file in an isolated, controlled environment. This process observes runtime behaviors such as process creation, registry modification, network communications, command-and-control callbacks, file system changes, and exploit attempts. These behaviors provide high-fidelity indicators that static analysis or hash lookups cannot reveal.
Option B, reviewing the directory path, is useful for contextual awareness but does not determine whether the file is malicious. Option C, running a full malware scan, is premature; modern malware often evades signature-based scans, especially when the file is previously unknown. Option D, investigating the reputation of the website, is a supporting activity but does not assess the actual behavior or payload of the downloaded file.
From a threat hunting and incident response standpoint, sandboxing bridges the gap betweendetection and confirmation. If the sandbox analysis confirms malicious behavior, the team can escalate to containment actions such as isolating the endpoint, blocking hashes and domains, and performing scope analysis to identify other affected systems. Additionally, sandbox results can be used to create new SIEM detections and EDR behavioral rules, strengthening future defenses.
This approach aligns with professional best practices:unknown file + untrusted source = dynamic analysis first. It ensures accurate classification while minimizing unnecessary disruption to the user or environment.
