Malware Analysis

Malware analysis helps defenders understand what a malicious file does so they can detect, contain and remove it. This roadmap focuses on safe, defensive analysis. You need Windows and Linux basics and an isolated lab.

• Build an isolated analysis lab with no access to your real network
• Understand safe handling rules
• Plan your study time

• CyberA4U Academy — courses

Malware must only be handled in isolated virtual machines with snapshots, no shared folders and controlled networking. REMnux and FLARE-VM provide ready-made toolsets.

• Isolate analysis VMs from your real network
• Use snapshots and reset after every sample
• Follow safe handling rules for samples

الأدوات والتقنيات: Malware

• REMnux documentation
• Mandiant FLARE-VM

Static analysis examines a file without running it: hashes, file type, strings, imports and embedded resources give a first picture of its purpose.

• Identify file type and hashes
• Extract strings and imports
• Form hypotheses about capability

الأدوات والتقنيات: Malware

• Microsoft Sysinternals — Strings

Windows PE and Linux ELF formats describe how executables are loaded. Their headers and sections reveal compile details, imports and anomalies.

• Read PE and ELF headers and sections
• Spot unusual sections and entropy
• Understand imports and exports

الأدوات والتقنيات: Malware

• Microsoft — PE Format
• elf(5) — Linux manual page

Strings and imported functions often reveal URLs, file paths, registry keys and capabilities such as networking or encryption.

• Extract ASCII and Unicode strings
• Interpret suspicious API imports
• Avoid over-reading obfuscated data

الأدوات والتقنيات: Malware

• Microsoft Sysinternals — Strings

Dynamic analysis runs the sample in a monitored, isolated VM to observe processes, files, registry and network activity.

• Monitor with Process Monitor and similar tools
• Capture network activity safely
• Revert after each run

الأدوات والتقنيات: Malware

• Microsoft Sysinternals — Process Monitor

Automated sandboxes run samples and produce behavior reports quickly, helping triage many files.

• Submit samples to a sandbox safely
• Read behavior reports
• Know sandbox limitations and evasion

الأدوات والتقنيات: Malware

• CAPE Sandbox documentation

Network indicators — domains, IPs, URLs and protocol patterns — let defenders block and hunt for malware across the organization.

• Extract network indicators from analysis
• Distinguish strong and weak indicators
• Share them in a usable format

الأدوات والتقنيات: Malware

• David Bianco — The Pyramid of Pain

Malware survives reboots through persistence: registry run keys, services, scheduled tasks and more. Finding them is key to full removal.

• Know common persistence locations
• Check them during analysis
• Map them to ATT&CK

الأدوات والتقنيات: Malware

• MITRE ATT&CK — Persistence (TA0003)

Packers and obfuscation hide code from analysts and scanners. Recognizing them tells you when deeper analysis is needed.

• Recognize signs of packing (high entropy, few imports)
• Understand common obfuscation techniques at a high level
• Decide when to escalate

الأدوات والتقنيات: Malware

• MITRE ATT&CK — Obfuscated Files or Information (T1027)

Many attacks use scripts — PowerShell, JavaScript, VBA macros — which are readable but often obfuscated. Script logging helps defenders see what ran.

• Recognize malicious script patterns
• Enable PowerShell script block logging
• Safely deobfuscate simple scripts

• Microsoft — about_Logging_Windows (PowerShell logging)

YARA rules describe patterns that identify malware families, used for hunting and classification.

• Write YARA rules with strings and conditions
• Test rules to avoid false positives
• Share rules responsibly

الأدوات والتقنيات: Malware

• YARA documentation

A good malware report explains capabilities, indicators, detections and recommended actions for defenders.

• Structure a malware report
• Share indicators in STIX or CSV
• Include detection and remediation advice

الأدوات والتقنيات: Malware

• OASIS — STIX and TAXII documentation

Mapping malware behavior to MITRE ATT&CK techniques helps defenders connect it to detections and threat intelligence.

• Map observed behaviors to techniques
• Use ATT&CK software entries
• Share mappings with detection engineers

الأدوات والتقنيات: Malware

• MITRE ATT&CK — Getting started

Scripts and pipelines automate repetitive triage: hashing, strings, YARA scans and sandbox submissions.

• Automate first-pass triage
• Scan collections with YARA
• Store results consistently

الأدوات والتقنيات: Malware

• YARA documentation

Studying published analyses from trusted sources shows how professionals structure findings, indicators and detections.

• Read a professional malware report critically
• Identify analysis techniques used
• Extract lessons for your own reports

الأدوات والتقنيات: Malware

• MITRE ATT&CK — Software

Check that you can safely triage a suspicious file and produce useful indicators and detections for defenders.

• Analyze safely in an isolated lab
• Combine static and dynamic analysis
• Report indicators and ATT&CK mappings

• CyberA4U CTF Arena — practice challenges

You can now perform defensive malware triage. Continue with Detection Engineering, Digital Forensics or Threat Intelligence.

• Keep your lab isolated and updated
• Choose your next roadmap
• Share a report write-up
