The SOC team found a suspicious document file on a user’s workstation. Upon initial inspection, the document appears benign, but deeper analysis reveals an embedded PowerShell script. The team suspects the script is designed to download and execute a malicious payload. They need to understand the script’s functionality without triggering it. Which malware analysis technique would be recommended technique for the SOC team to understand the PowerShell script's functionality without executing it?

During a routine threat intelligence briefing, a SOC analyst comes across a classified report detailing a sophisticated cybercrime syndicate targeting executives of high-profile financial institutions. Unlike traditional malware-based attacks, these adversaries rarely leave digital footprints and seem to anticipate security measures in advance. While analyzing recent incidents, the analyst discovers that several breaches began with seemingly innocent conversations – a foreign journalist requesting an interview with a CEO, and a security consultant offering free risk assessments. Further investigations reveal that attackers socially engineered employees, manipulated trust, and extracted critical security details long before launching technical attacks. Realizing that the most valuable intelligence may not come from log files or malware analysis, the analyst decides to focus on intelligence that involves deception detection, and psychological profiling to uncover the true intent and methods of the attackers. Which type of intelligence is the analyst leveraging in this situation?

Mark Reynolds, a SOC analyst at a healthcare organization, is monitoring the SIEM system when he detects a potential security threat: a series of unusual login attempts targeting critical patient data servers. After investigating the alerts and collaborating with the incident response team, the SOC determines that the threat has a "Likely" chance of occurring and could cause "Significant" damage, including operational disruptions, financial loss due to data breaches, and regulatory penalties under HIPAA. Using a standard Risk Matrix, how would this risk be categorized in terms of overall severity?

During routine monitoring, the SIEM detects an unusual spike in outbound data transfer from a critical database server. The typical outbound traffic for this server is around 5 MB/hour, but in the past 10 minutes, it has sent over 500 MB to an external IP address. No predefined signatures match this activity, but the SIEM raises an alert due to deviations from the server's normal behavior profile. Which detection method is responsible for this alert?

You are part of a team of SOC analysts in a multinational organization that processes large volumes of security logs from various sources, including firewalls, IDS, and authentication servers.
