Modern cyberattacks are no longer single-purpose—they’re multi-layered, profit-driven operations.
A newly discovered campaign is delivering two distinct malware payloads in one infection: the infamous Gh0st RAT and the monetization-focused CloverPlus adware.
This dual-payload approach allows attackers to:
👉 Maintain long-term remote control
👉 Generate immediate revenue through ad fraud
All from a single compromised machine.
For security teams, this represents a critical shift:
Attackers are maximizing ROI per infection.
In this article, you’ll learn:
- How this dual malware campaign works
- Why combining RAT + adware is effective
- Technical breakdown of the loader and execution chain
- Detection and mitigation strategies
- Best practices aligned with modern frameworks
What Is the Gh0st RAT & CloverPlus Campaign?
A New Multi-Payload Threat Model
The campaign uses a single obfuscated loader to deploy:
- Gh0st RAT → persistent backdoor & espionage
- CloverPlus adware → browser hijacking & monetization
This combination enables attackers to:
- Steal sensitive data
- Maintain persistent access
- Generate ad revenue simultaneously
Why This Combination Matters
Traditionally:
- RATs = long-term espionage
- Adware = short-term profit
Now:
👉 Both objectives are achieved in one attack chain
How the Attack Works: Full Execution Chain
Step-by-Step Breakdown
1. Initial Infection
Victim executes a malicious loader:
- Obfuscated binary
- Contains encrypted payloads
2. Adware Deployment First
The loader extracts:
- CloverPlus module (
wiseman.exe)
Actions:
- Modifies browser settings
- Injects pop-up ads
- Alters homepage
3. Self-Replication
The loader checks its location:
- If not in
%temp%, it copies itself there
👉 Helps evade detection and persist execution
4. RAT Payload Decryption
The loader decrypts:
- Gh0st RAT DLL
- Stored in encrypted resource section
5. Stealth Execution via Rundll32
The malware executes using:
rundll32.exe(legitimate Windows process)
👉 Blends malicious activity with trusted system behavior
6. System Profiling
Gh0st RAT collects:
- MAC address
- Disk serial number
Used for:
- Victim identification
- C2 tracking
7. Persistence Mechanisms
The malware ensures survival via:
- Windows Run registry keys
- Remote Access service hijacking
👉 Achieves SYSTEM-level execution
Why This Campaign Is Dangerous
1. Dual Impact Attack
- Data theft + monetization
- Immediate + long-term value
2. Trusted Process Abuse
- Uses
rundll32.exe - Evades signature-based detection
3. Obfuscation & Encryption
- Payloads hidden in resources
- Harder for static analysis tools
4. Persistent Backdoor Access
- Survives reboots
- Maintains control indefinitely
Real-World Impact
For Individuals
- Browser hijacking
- Exposure to malicious ads
- Data theft
For Organizations
- Credential compromise
- Network infiltration
- Financial and reputational damage
Mapping to MITRE ATT&CK
This campaign aligns with MITRE ATT&CK:
| Tactic | Technique |
|---|---|
| Execution | Rundll32 Proxy Execution |
| Persistence | Registry Run Keys |
| Credential Access | Keylogging |
| Defense Evasion | Obfuscated Files |
| Command & Control | DNS & Web Traffic |
Common Security Gaps Exploited
❌ Weak Endpoint Monitoring
Traditional tools miss multi-stage payloads.
❌ Lack of Behavior Analysis
Focus on signatures instead of execution patterns.
❌ Unmonitored Temporary Directories
Malware often executes from %temp%.
❌ Insufficient Registry Monitoring
Persistence mechanisms go unnoticed.
Detection & Threat Hunting
Indicators of Compromise (IoCs)
- Execution of
rundll32.exefrom unusual paths - Processes running from
%temp% - Registry changes in Run keys
- Suspicious DNS traffic
SOC Monitoring Strategies
- Track process execution chains
- Monitor registry modifications
- Analyze network anomalies
Mitigation & Defense Strategies
1. Strengthen Endpoint Detection
Deploy advanced EDR solutions capable of:
- Behavioral analysis
- Memory inspection
2. Monitor Trusted Binary Abuse
Flag:
rundll32.exeexecuting unknown DLLs- Non-standard execution paths
3. Restrict Temporary Directory Execution
- Block execution from
%temp% - Apply application control policies
4. Harden Registry Protections
- Monitor Run key modifications
- Alert on service changes
5. Network Monitoring
- Detect abnormal DNS patterns
- Identify suspicious outbound traffic
6. Align with Security Frameworks
Follow guidance from NIST:
- SI-4: System monitoring
- AC-6: Least privilege
- SI-7: Software integrity
Expert Insight: Risk Analysis
Likelihood: High
Impact: High
Why?
- Multi-payload efficiency
- Stealthy execution
- Persistent access
Business Impact
- Data breaches
- Financial losses
- Operational disruption
FAQs
What is Gh0st RAT?
A remote access trojan that allows attackers to fully control infected systems.
