Compromised Assessment

compromised assessments

A Compromise Assessment is a detailed evaluation process aimed at identifying and detecting unknown threats within an organization's network. It involves a thorough examination to uncover indicators of compromise and signs of malicious activity that might have bypassed existing security measures. The assessment begins with identifying and detecting unknown threats within the network.

This is followed by comprehensive scanning of endpoints using Sigma, YARA, and various IOCs repositories to detect hidden threats. Sigma rules facilitate the detection of known attack patterns in log data, while YARA rules help identify and classify malware samples or malicious files based on patterns. By integrating these methodologies, a Compromise Assessment provides a robust mechanism to uncover and address stealthy threats, ensuring the organization's security posture is thoroughly evaluated and fortified against potential breaches.

Key Components of Compromise Assessment

Scanning for Known Malware: Utilizing signature-based detection methods to identify and eliminate known malware variants.
Detection of Unknown Malware: Implementing heuristic and behavior-based analysis techniques, employing advanced detection tools such as YARA, IOCs, Artifacts, and Sigma rules to identify previously unknown or obfuscated malware.

Continuous Monitoring: Employing real-time network monitoring solutions to capture and analyze data packets, identifying unusual patterns, traffic spikes, or anomalies indicative of malicious activity.
Protocol Analysis: Inspecting network protocols to detect deviations from standard behaviors that may suggest covert communication channels or data exfiltration attempts.

System Log Review: Analyzing logs from operating systems to detect unauthorized changes, login attempts, and privilege escalations.
Application Log Review: Scrutinizing application logs for irregularities, errors, or security warnings that could signal attempted or successful exploits.
Security Log Review: Assessing security device logs, such as firewalls and intrusion detection/prevention systems, to identify and correlate security events and alerts.

File System Examination: Inspecting files and directories on endpoints for unauthorized modifications, unexpected executables, and hidden files.
Configuration Audit: Reviewing system and application configurations for unauthorized changes, misconfigurations, or deviations from security policies.
Memory Analysis: Conducting volatile memory analysis to detect in-memory malware, rootkits, and other advanced persistent threats (APTs).

Malware Reverse Engineering: Disassembling and analyzing malware samples to understand their behavior, extract unique artifacts, and identify tactics, techniques, and procedures (TTPs).
Custom Rule Development: Creating tailored YARA and Sigma rules based on extracted IOCs to enhance detection capabilities.
Detection Queries: Formulating specific detection queries for security information and event management (SIEM) systems to identify and alert the presence of IOCs within the network environment.

Why do companies need it?

Detect Hidden Threats

Cyber threats can often go undetected for long periods. A compromise assessment helps uncover hidden threats that might have been bypassed.

Enhanced Security Posture

A compromise assessment provides insights into the current security weaknesses and vulnerabilities within an organization's infrastructure. By addressing these vulnerabilities, companies can significantly enhance their overall security posture, making them more resilient to future attacks.

Cost Savings

The financial impact of a data breach can be substantial. A compromise assessment helps prevent costly incidents by identifying and mitigating risks before they materialize.
