300-215 Exam Dumps : Conducting Forensic Analysis and Incident Response Using Cisco CyberOps Technologies (CBRFIR)

Process injectionis a tactic where malicious code is inserted into the memory space of another process, enabling it to run with the privileges and context of a legitimate application. The Cisco study guide explains that this method allows malware to "hide in plain sight" within trusted processes and evade endpoint detection and response (EDR) tools.

It specifically notes:"Process injection techniques allow malware to execute within the memory space of a legitimate process, avoiding detection and taking advantage of the process's permissions.".

The string shown is long, alphanumeric, and includes both uppercase and lowercase letters with numbers—characteristics of Base64 encoding. This format is widely used to obfuscate payloads in malicious scripts, particularly in phishing or malware campaigns. Base64 encoding is also supported by Python and other platforms for data transformation.

The goal of the given Python code is to parse an Apache access log and extract IP addresses using regular expressions (regex). In this context, the most appropriate regex pattern to extract IPv4 addresses from log data is:

r'\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}'

This pattern matches typical IPv4 addresses, where each octet consists of 1 to 3 digits separated by periods. For example, it matches addresses like192.168.1.1or10.0.0.123. The pattern uses:

\d{1,3}to capture between 1 and 3 digits,

\.to match the dot (escaped since.is a special character in regex),

repeated 4 times with proper separation to form the full IPv4 structure.

Options A, B, and C either include incorrect syntax, improper escape sequences, or do not represent a valid IP address pattern.

This type of log analysis and pattern extraction is described in the Cisco CyberOps Associate curriculum under basic scripting and automation techniques used in log and artifact analysis.
