1. • Network connections from infected machines to known Pushdo command and control (C2) servers.
   • Suspicious registry modifications or process injections pointing to Pushdo activity.
2. Visualize Findings in Kibana: Import your Squil-generated data into Kibana and create visualizations to analyze trends and patterns. Look for spikes in events, frequent connections to specific IP addresses, and correlations between different types of activities.

Task 2: Leveraging Google Search for Threat Intelligence

1. Refine Your Search: Armed with specific details from your event analysis, formulate targeted Google searches. Include keywords like "Pushdo IOCs," "Pushdo latest campaigns," or "Pushdo analysis reports."
2. Vet Your Sources: Prioritize reputable sources like security blogs, threat intelligence vendors, and incident response reports. Be wary of personal blogs or forums with unverified information.
3. Extract Key Insights: Identify relevant indicators of compromise (IOCs) like Pushdo file hashes, C2 server domains, and malware signatures. Look for insights into Pushdo's attack vectors, targeted vulnerabilities, and potential mitigation strategies.

Task 3: Verification with VirusTotal

1. Upload Suspicious Files: Identify any suspicious files identified during your analysis, such as downloaded executables or modified system files. Upload them to VirusTotal for scanning by multiple antivirus engines and analysis tools.
2. Interpret Scan Results: Analyze the scan results for Pushdo detections. Look for high detection rates, associated malware families, and additional details like file type and origin.
3. Correlate Findings: Combine VirusTotal results with your other analysis to determine the level of risk and potential impact of the identified Pushdo activity.

Reporting and Next Steps: Once you've completed these tasks, prepare a comprehensive report summarizing your findings. Include details about the identified Pushdo activity, associated IOCs, potential impact, and recommended mitigation steps. Remember, collaboration is key! Consult with senior analysts and security teams to discuss your findings and determine the appropriate response. This exercise is just the beginning of your journey as a cybersecurity analyst. Be prepared to constantly learn, adapt, and hone your skills as you navigate the ever-evolving threat landscape. Remember, even a junior analyst can play a crucial role in keeping your organization safe from cyber threats. Good luck! Bonus Tip:

• Explore additional threat intelligence platforms like MITRE ATT&CK, Crowdstrike Falcon X, and AlienVault OTX to further enrich your analysis and understanding of Pushdo behavior.
