Threat Intelligence and Malware Analysis: Staying Ahead of Adversaries Threat intelligence and malware analysis help security teams stay ahead of adversaries. By combining data about attackers, tools, and how malicious software behaves, organizations can prepare defenses, speed up detection, and reduce damage. This post offers a practical approach that fits many teams, from small shops to larger security operations centers. A short threat intelligence loop includes five steps: collection, enrichment, analysis, dissemination, and action. Collect data from internal alerts, firewall and endpoint telemetry, and public feeds. Enrich it with context such as actor, tactic, targets, and expected malware families. Analyze patterns in samples and traffic, identify common behaviors, and track new IOCs over time. Share insights with incident responders and security engineers, and use the findings to tune rules, dashboards, and playbooks. ...

Threat Hunting: Proactive Malware and Adversary Analysis Threat hunting is a proactive security practice. Teams search for signs of malware and adversaries in the network before users notice a problem. The aim is to find hidden threats, understand how an attacker operates, and stop damage early. A successful hunt uses data from multiple sources, combines practical skills with threat intelligence, and follows repeatable steps. What threat hunting looks for Unusual authentication patterns, such as logins from new devices or odd times Unknown or modified executables and scripts Lateral movement between machines New or hidden persistence mechanisms like unauthorized services Data exfiltration signals or unusual network traffic Suspicious PowerShell, WMI, or scripting activity Practical steps for hunters Establish a normal baseline of user and device behavior Form a testable hypothesis about a potential threat Collect data from endpoints, networks, and logs Run focused searches for indicators of compromise Correlate findings with threat intelligence Validate, contain, and remediate to block the threat Document findings and update playbooks for future hunts Tools and methods Endpoint detection and response (EDR) and alert rules SIEM searches and log analytics Memory forensics to inspect suspicious processes Network traffic analysis to spot beaconing or C2 calls Automated checks can help but human review is still essential A simple example Consider a PowerShell process that runs with a long encoded command. A hunter checks memory, event logs, and the parent process to see if this matches a known IOC. If it does, the team blocks the command, isolates the host, and updates detection rules to catch similar activity in the future. ...
