🔍 What is BADBOX 2.0?

BADBOX 2.0 is an advanced malware attack first detected by HUMAN Security’s Satori Threat Intelligence team. It is a major expansion of the original BADBOX campaign discovered in 2023.

Here’s how this attack works:

✅ Fake Apps on Google Play – Hackers uploaded 24 malicious apps that looked like real applications.
✅ Backdoor Installation – Once installed, these apps secretly downloaded and executed additional malicious files.
✅ Fraudulent Ad Traffic & Click Fraud – The infected apps generated billions of fake ad clicks, making money for the attackers.
✅ Persistent Control Over Devices – The malware installed a hidden backdoor called BB2DOOR, allowing hackers to maintain long-term access to affected systems.

What makes this attack unique is that the infected apps had “evil twins”—they shared package names with legitimate applications. This allowed them to bypass Google’s security checks and deceive users into thinking they were safe.

The backdoor worked by loading a malicious library called libanl.so that deployed fraud mechanisms to the device.

When activated, the code would download and install multiple files responsible for maintaining communication with command-and-control servers.

The following code snippet demonstrates how the backdoor initiated:-

.class public Lcom/hs/App;
.super Landroid/app/Application;
.source "SourceFile"
.method static constructor ()V
    .locals 2
    invoke-static {}, Ljava/util/concurrent/Executors;->newSingleThreadScheduledExec
    move-result-object v0
    sput-object v0, Lcom/hs/App;->b:Ljava/util/concurrent/ScheduledExecutorService;
    const-string v0, "anl"
    invoke-static {v0}, Ljava/lang/System;->loadLibrary(Ljava/lang/String;)V
    const-wide/32 v0, 0x1d4c0

The 24 malicious apps functioned as “evil twins” to legitimate applications in Google Play Store, sharing package names with legitimate “decoy twins” to appear legitimate in ad requests.
This deception allowed the threat actors to generate fraudulent ad traffic at a massive scale, with hidden ads schemes generating up to 5 billion fraudulent bid requests weekly.

🛑 Who is Behind BADBOX 2.0?

Security researchers identified four distinct cybercriminal groups working together on this malware operation:

🔹 SalesTracker Group
🔹 MoYu Group
🔹 Lemon Group
🔹 LongTV

These groups collaborated through shared infrastructure to carry out multiple fraud schemes, including:

💰 Click fraud – Faking ad interactions to steal advertising revenue.
💰 Residential proxy services – Hijacking infected devices to route fraudulent traffic.
💰 Ad fraud – Generating up to 5 billion fake ad requests weekly.

This wasn’t just a random malware outbreak—it was a highly organized cybercriminal operation designed to exploit users worldwide.

💡 How Google is Fighting Back

✅ Google Play Protect now blocks BADBOX-infected apps at the installation stage.
✅ Google has banned all accounts associated with BADBOX 2.0 from its advertising network.
✅ Play Protect-certified devices remain safe, but uncertified Android devices are still at risk.

Although Google has taken strong security measures, cyber threats evolve constantly, and users must remain vigilant.

🛡️ How to Protect Yourself from BADBOX 2.0

🔹 Check Your Device Certification

• Go to Settings > About Phone > Google Play Certification
• If your device is not certified, it may be vulnerable.

🔹 Enable Google Play Protect

• Open Google Play Store > Play Protect > Scan apps regularly.

🔹 Avoid Third-Party App Stores

• Only download apps from official sources like Google Play.

🔹 Monitor App Permissions

• If an app asks for sensitive permissions (camera, microphone, location) without a clear reason, delete it immediately.

🔹 Uninstall Unknown Apps

• If your device runs slow, overheats, or drains battery quickly, scan for malicious apps.
