This is the best method to operationalize these loCs to detect future attacks because it allows the company to collect, correlate, analyze, and alert on the indicators of compromise (loCs) from various sources and systems. A SIEM stands for security information and event management, which is a software or service that provides centralized visibility and management of security events and data.

The vulnerability scan report shows that the workstation has a high-risk vulnerability (CVE-2019-0708) that affects Remote Desktop Services on Windows systems. This vulnerability allows remote code execution without authentication or user interaction, and can be exploited by sending specially crafted requests to the target system1 As part of the detection and analysis procedures, the analyst should confirm the workstation’s signatures against the most current signatures. This can help verify if the workstation has been patched or updated to address the vulnerability, or if it is still vulnerable and needs remediation. The analyst can use tools such as Windows Update or Microsoft Baseline Security Analyzer to check the workstation’s patch level and compare it with the latest available signatures.

A honeypot is a decoy system that is designed to attract and trap attackers, by mimicking a real system or network, but containing fake or harmless data. A honeypot can be used to collect IoCs from multiple geographic regions, by deploying it in different locations or networks, and monitoring the activities or attacks that target it. A honeypot can also provide valuable threat intelligence data that can be sold to customers.

The calc entry is a suspicious registry entry that should be investigated first by the analyst. The calc entry is located in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run registry key, which is a common location for malware to persist and execute on system startup. The calc entry has a data value of “C:\Windows\System32\calc.exe”, which is the path to the legitimate Windows Calculator program. However, this program does not need to run on system startup, and it could be a disguise for a malicious executable that has replaced or renamed the original calculator program. The calc entry could also be a sign of a fileless malware attack, where the attacker uses the legitimate calculator program to execute malicious commands or scripts in memory1.
