40M Monthly Victims: The Pirate Site Malware That Mines Crypto AND Owns Your PC + Video

Introduction:

A sophisticated cybercrime gang has weaponized illegal movie, TV, and book streaming sites to distribute a hybrid malware that mines cryptocurrency while giving attackers complete remote control over infected devices. In late April 2026, Kaspersky’s incident response team uncovered a campaign that has been active since at least 2022, using fake video player update prompts to deliver a malicious ZIP archive containing a legitimate‑looking executable paired with a malicious DLL that side‑loads into trusted system processes. With over 40 million visits in April 2026 alone to the compromised websites, this operation demonstrates how attackers continuously refine infection chains to evade detection and maximize financial gain.

Learning Objectives:

– Understand the complete infection chain from social engineering prompt to payload execution
– Detect and remove SilentCryptoMiner and its associated RAT using forensic techniques on Windows/Linux
– Implement defensive controls and user‑awareness strategies to prevent DLL side‑loading and cryptojacking

You Should Know:

1. Dissecting the Infection Chain: From Fake Update to Full Compromise

The attack begins when a user attempts to stream content on a compromised pirate site. Instead of the requested video, a browser pop‑up claims the video player plugin is outdated and demands an immediate update. Clicking the link downloads a ZIP archive containing a legitimate executable—`HLS Installer.874.exe`—and a heavily obfuscated malicious DLL. When the EXE runs, it employs a DLL side‑loading technique: placing the rogue library in the same directory forces the trusted process to load it, bypassing many security heuristics by masquerading as legitimate software.

The malicious DLL contains a stack buffer overflow that builds a Return‑Oriented Programming (ROP) chain to decrypt and launch the secondary payload. The shellcode is embedded within the executable’s modified DOS header, a clever hiding technique that evades static analysis. Before activation, the malware validates the victim via DNS tunneling, spoofing Microsoft domain names to blend with normal telemetry traffic. Only after receiving a specific approval signal does it proceed—a clear attempt to avoid sandbox and research environments.

Once activated, the payload runs a customized version of the open‑source SilentCryptoMiner alongside a RAT module. The malware registers a persistent scheduled task named `GoogleUpdateTaskMachineQC` and hides its working files in `C:\ProgramData\Google\Chrome\`, masquerading as Google components. A watchdog component injected into `explorer.exe` checks every five seconds for the miner’s presence and restores it from an encrypted backup if deleted.

Step‑by‑step detection & removal (Windows):

 1. Identify suspicious processes using high CPU
Get-Process | Sort-Object CPU -Descending | Select -First 10

 2. List scheduled tasks with Google‑masquerading names
schtasks /query /fo LIST /v | findstr "GoogleUpdateTaskMachineQC"

 3. View hidden service and its binary path
sc qc GoogleUpdateTaskMachineQC

 4. Terminate the watchdog inside explorer.exe (must be done first)
taskkill /f /im explorer.exe
 Then relaunch Explorer after cleaning

 5. Delete the malicious scheduled task
schtasks /delete /tn "GoogleUpdateTaskMachineQC" /f

 6. Remove the malware directory
rmdir /s /q "C:\ProgramData\Google\Chrome\updater"

Step‑by‑step detection (Linux – miner behaves similarly on compromised servers):

 Detect high CPU usage without legitimate explanation
top -c

 List all processes with network connections
netstat -tulnp | grep ESTABLISHED

 Search for hidden processes using unhide
unhide proc

 Check crontab for persistence
crontab -l

2. Evasion & Persistence: How the Malware Avoids Detection

The malware employs multiple layers of stealth to resist removal. It disables Windows Defender by adding exclusions for its own paths and terminates the Microsoft Malicious Software Removal Tool if detected. If running with administrative privileges, it modifies system power configurations to keep hardware running at maximum capacity for mining operations—a telltale sign for incident responders.

The watchdog component is exceptionally resilient: it runs inside `explorer.exe`, monitoring the miner’s presence and any attempts to delete its files or terminate its processes. Every five seconds it checks for the miner and restores it from an encrypted backup stored in memory. Security teams must first terminate the watchdog inside Explorer before any cleanup, otherwise the miner reinstalls itself within seconds.

To evade network‑level detection, the RAT communicates over DNS tunneling, disguising traffic as normal Microsoft telemetry. It can execute arbitrary commands, load additional executables into memory, and run shellcode directly—providing full remote access while avoiding signature‑based detection.

Step‑by‑step detection for defenders:

 Detect Windows Defender exclusions added by malware
Get-MpPreference | Select-Object -ExpandProperty ExclusionPath

 Search for processes running under explorer.exe (watchdog)
Get-Process | Where-Object {$_.Parent -eq (Get-Process explorer).Id}

 Monitor DNS tunnel activity via PowerShell
Get-1etUDPEndpoint | Where-Object {$_.LocalPort -eq 53} | Format-Table

 Use Sysmon to log DLL loads (Install Sysmon first)
& 'C:\Tools\Sysmon64.exe' -accepteula -i

 Hunt for DLL side‑loading using PowerShell (DLLHound tool)
git clone https://github.com/ajm4n/DLLHound.git
cd DLLHound
.\DLLHound.ps1

3. Infrastructure Takeover: Exposed APIs and Cloud Cryptojacking

The same threat actor has been observed expanding beyond end‑user devices into cloud environments. Unauthenticated and misconfigured Docker API endpoints are actively scanned and exploited for cryptomining. Attackers use tools like `masscan` and `ZGrab` to identify exposed Docker daemons, then deploy miners directly onto containers. Organizations with poorly secured cloud APIs are at high risk of having their compute resources hijacked for cryptocurrency mining.

API security misconfigurations—such as missing authentication, overly permissive CORS policies, and lack of rate limiting—allow attackers to not only mine but also pivot into internal networks. This campaign illustrates how the same social engineering that infects home users can be scaled to corporate cloud infrastructure via exposed management interfaces.

Cloud hardening steps:

 Linux: Check for exposed Docker daemon
netstat -tulnp | grep :2375

 Ensure Docker uses TLS and authentication
 Create a directory for certificates
mkdir -p ~/.docker/certs.d

 Restart Docker with TLS enabled
sudo dockerd --tlsverify \
--tlscacert=~/.docker/certs.d/ca.pem \
--tlscert=~/.docker/certs.d/server-cert.pem \
--tlskey=~/.docker/certs.d/server-key.pem \
-H=0.0.0.0:2376

 Scan for exposed Kubernetes API servers
nmap -p 6443 --open <target_network>/24

 Apply strict network policies in Kubernetes
kubectl apply -f - <<EOF
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
name: deny-all
spec:
podSelector: {}
policyTypes:
- Ingress
- Egress
EOF

4. Social Engineering at Scale: Why Users Keep Falling for Fake Updates

The campaign’s success hinges on psychological manipulation: users expect plugin updates on streaming sites, and the fake prompt mimics legitimate software update dialogs. The threat actor has refined this lure since 2022, changing domains and delivery mechanisms while keeping the core deception intact. Compromised sites range from small digital libraries with 11,000 monthly users to massive streaming platforms reaching 27.4 million visitors.

User awareness training must emphasize:

– Never download updates from third‑party pop‑ups; always use official app stores or vendor websites
– Enable browser settings that block automatic downloads
– Verify file hashes and digital signatures before running any executable

Command to verify digital signatures (Windows):

Get-AuthenticodeSignature -FilePath "HLS Installer.874.exe"

Linux verification of downloaded archives:

 Check file type before execution
file suspicious.zip

 Extract and examine contents safely in a sandbox
unzip -t suspicious.zip

 Compare hash with known good version
sha256sum suspicious.zip

In addition, hands‑on practice with tools like Process Explorer, Sysmon, Wireshark, and custom PowerShell scanners (e.g., DLLHound) is essential for detecting side‑loading and miner‑RAT hybrids.

What Undercode Say:

– Key Takeaway 1: The hybrid miner‑RAT campaign represents a dangerous evolution in cybercrime—attackers are no longer satisfied with passive cryptojacking but demand full remote access to pivot, exfiltrate data, or deploy additional malware. This dual‑purpose payload dramatically increases the risk profile for any organization.
– Key Takeaway 2: Defensive strategies must shift from simple signature‑based detection to behavioral analysis. The malware’s use of DNS tunneling, embedded shellcode in DOS headers, and a watchdog inside Explorer demands advanced endpoint detection and response (EDR) solutions that monitor process ancestry, memory patterns, and API call sequences—not just static file scans.

Analysis: The campaign’s sophistication is matched only by its scale. With 40 million potential victims monthly, the threat actor has effectively weaponized the pirate content ecosystem. However, the reliance on DLL side‑loading and scheduled task persistence provides clear forensic artifacts. Organizations that implement least‑privilege access, enforce application whitelisting, and conduct regular user awareness training can significantly reduce their attack surface. The emergence of RAT capabilities alongside miners suggests a move toward multi‑stage monetization: first establish persistence via mining, then sell remote access or use it for targeted attacks. This blurs the line between opportunistic crimeware and state‑sponsored tactics.

Prediction:

– +1 Positive shift in defense: The publicity around this campaign will accelerate adoption of behavioral EDR and automated response tools that can terminate watchdog processes and isolate infected endpoints without human intervention.
– -1 Increased targeting of home users: As corporate defenses improve, attackers will double down on infecting personal devices via pirate sites, using them as proxies to launch attacks on corporate VPNs and cloud services, leading to a rise in supply‑chain compromises.
– -1 Rise of anti‑forensic techniques: Expect future variants to encrypt the watchdog’s backup storage and use process hollowing to hide within system processes, making detection significantly harder and requiring memory forensics at scale.
– +1 Cloud API hardening becomes standard: The use of exposed Docker APIs for mining will force cloud providers to enforce default‑deny network policies and mandatory authentication, reducing the attack surface for cryptojacking.
– -1 Pirate site operators become complicit: As these campaigns prove profitable, some pirate site administrators may start intentionally bundling miners or RATs in exchange for payment, creating a new malware‑as‑a‑service model for illegal streaming platforms.
