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

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 described scenario includes both internal alerts (unusual network traffic, failed logins, suspicious file access) and external intelligence indicating active ransomware campaigns in the same industry. This constitutes a strong combination of precursors and indicators, as defined in the NIST SP 800-61 incident handling model and reinforced in the Cisco CyberOps Associate curriculum.

According to the Cisco guide:

“Once an incident has occurred, the IR team needs to contain it quickly before it affects other systems and networks within the organization.”

“The containment phase is crucial in stopping the threat from spreading and compromising more systems”.

Given these indicators and the high-value nature of the data involved, it is essential to proactively isolate suspected systems and activate the incident response plan to prevent damage from potential ransomware.

The command in the image usesschtasks /createwith theONLOGONschedule andSystemuser context to executetest.exe. This is a well-documented persistence technique, where an attacker ensures that a malicious executable is launched automatically at each system logon. This kind of scheduled task creation aligns with persistence techniques in the MITRE ATT&CK framework (T1053).
