Defensive strategies for malware
Detecting malware installation is a critical component of incident response, as early detection can significantly mitigate the impact of a cyber-attack. Incident response teams employ various techniques to identify malicious software on systems. Here are some of the most common methods:
- Behavioral analysis: Behavioral analysis involves monitoring and analyzing the behavior of program and system processes to identify anomalies indicative of malware. This technique is based on the principle that malicious software often exhibits unusual behavior patterns, such as:
- Unexpected network activity: Malware may attempt to communicate with command and control (C2) servers, leading to unusual outbound traffic patterns.
- File and registry changes: Malware installation often involves creating or modifying files and registry entries to achieve persistence.
- Process anomalies: Unusual processes or services running on the system, especially those with high privileges...
