We’re excited to announce the launch of http://malops.io, a platform built by analysts, for analysts, and it’s completely free. You can join and engage with their first challenge about RokRat Loader.
You Should Know:
Analyzing RokRat Loader – Key Steps & Commands
RokRat is a malware family associated with Korean threat actors, often used in targeted attacks. Below are key techniques and commands to analyze such threats:
1. Basic Static Analysis
- File Hashing (SHA-256, MD5, SHA-1)
sha256sum rokrat_sample.exe md5sum rokrat_sample.exe sha1sum rokrat_sample.exe
- Strings Extraction
strings -n 8 rokrat_sample.exe | less
- PE File Analysis
file rokrat_sample.exe objdump -x rokrat_sample.exe
2. Dynamic Analysis (Sandboxing & Monitoring)
- Sysmon Logging (Windows)
sysmon -accepteula -i config.xml
- Process Monitoring (Linux/Windows)
procmon (Windows) strace -f -o rokrat_trace.txt ./rokrat_sample.exe (Linux)
- Network Traffic Capture
tcpdump -i eth0 -w rokrat_traffic.pcap
3. Memory Forensics (Volatility)
- Dump Process Memory
volatility -f memory_dump.raw pslist volatility -f memory_dump.raw malfind --dump-dir=./output
- Extract API Calls
volatility -f memory_dump.raw apihooks
4. YARA Rule for Detection
rule RokRat_Loader {
meta:
description = "Detects RokRat Loader"
author = "YourName"
strings:
$s1 = "RokRat" nocase
$s2 = { 6A 40 68 00 30 00 00 6A 14 }
condition:
any of them
}
5. MITRE ATT&CK Mapping
- T1055 (Process Injection)
- T1071 (Command and Control)
- T1027 (Obfuscated Files or Information)
What Undercode Say
MalOps.io is a valuable resource for threat analysts, offering hands-on challenges like RokRat analysis. Combining static and dynamic analysis techniques with memory forensics provides a comprehensive approach to dissecting malware. The platform’s free access democratizes threat intelligence, empowering security researchers globally.
Expected Output:
- Static Analysis: Hashes, strings, and PE structure.
- Dynamic Analysis: Process behavior, network traffic logs.
- Memory Forensics: Injected processes, API hooks.
- YARA Rule: Detection signature for RokRat.
Prediction
As threat actors evolve, platforms like MalOps.io will become essential for collaborative malware research, leading to faster detection and mitigation of emerging threats.
