A new and highly dangerous Android malware called Crocodilus is making waves in the crypto world. First uncovered by Threat Fabric in March 2025, Crocodilus poses a severe threat to Android 13 and newer devices, specifically targeting users of cryptocurrency wallets. Using a combination of social engineering, fake overlays, keylogging, and remote access, this malware is designed to steal digital assets with alarming precision.
How Crocodilus Infects Android Devices
Crocodilus doesn’t rely on just one method—it spreads through a variety of deceptive techniques:
Fake Crypto Apps
Disguised as trusted cryptocurrency tools or wallets, Crocodilus bypasses Google Play Store protections and is commonly found on third-party app stores.
SMS Phishing Links
The malware spreads via SMS messages containing malicious links. Once clicked, the link redirects users to websites that auto-download the malware.
Phishing Emails
Impersonating major crypto exchanges, emails trick users into downloading what appears to be a wallet update or security tool.
Malicious Ads
Unsafe ads hosted on shady websites can install Crocodilus with just one tap, especially if a device is already compromised or lacks updated protections.
After installation, the malware requests accessibility service permissions, giving it control over the device. From there, it connects to a command-and-control (C2) server, allowing it to operate stealthily in the background.
How Crocodilus Steals Cryptocurrency
Crocodilus is far more advanced than typical malware. It uses a combination of attack vectors to extract sensitive wallet data:
Fake Wallet Overlays
The malware mimics the interface of popular crypto wallets and prompts users to input seed phrases under the guise of backing up the wallet. These phrases are then sent to attackers.
Keylogging
Every keystroke, from PINs and passwords to wallet recovery phrases, are monitored and logged.
2FA Bypass
By capturing screens and intercepting input, Crocodilus can access 2FA codes from apps like Google Authenticator or SMS, rendering your second layer of protection useless.
Full Remote Access
Attackers can open apps, manipulate settings, activate cameras, or even send texts from the infected device, giving them near-complete control.
How to Detect and Prevent Crocodilus Malware
Early detection is vital. Look for these signs:
- Sudden battery drain
- Unusual spikes in data usage
- Unknown apps or strange permissions
- Sluggish device behavior
Prevention Tips:
- Avoid clicking suspicious links from emails or text messages
- Only download apps from the official Google Play Store
- Use hardware wallets for secure crypto storage
- Review app permissions regularly, especially for apps with access to sensitive information
- Stay informed through reliable cybersecurity sources for updates on threats like Crocodilus
Stay Vigilant: The Threat of Crocodilus Is Real
Crocodilus represents a new frontier in Android malware, particularly in its focus on digital asset theft. As the malware becomes more sophisticated, crypto investors must take proactive steps to secure their assets. With strong cybersecurity hygiene and the use of secure wallets, users can significantly reduce the risk of falling victim to this stealthy crypto predator.
