Crocodilus Malware : How Hackers Are Stealing Crypto Through Android Apps

Crocodilus is the latest and most dangerous malware targeting Android crypto wallets, threatening digital assets with sophisticated tactics. First discovered by Threat Fabric in March 2025, this malware primarily targets Android 13 devices or later. With a focus on crypto wallets, Crocodilus uses overlays, remote access, and social engineering to hijack devices and drain assets.

How Crocodilus Infects Android Devices

Crocodilus employs several infection methods, making it a formidable threat. The most common entry points include:

• Fake Apps: Crocodilus can disguise itself as legitimate cryptocurrency apps, bypassing Google Play Store security measures. It may also lurk on third-party app-hosting sites, waiting for unsuspecting users to download it.
• SMS Scams: Malicious links sent via SMS can redirect users to pages where Crocodilus automatically downloads to the device.
• Phishing Emails: Fake emails impersonating crypto exchanges prompt users to download the malware, leading to device compromise.
• Malicious Ads: Ads on dubious websites can initiate malware downloads with just one accidental tap.

Once installed, Crocodilus requests accessibility service permissions, enabling it to connect to its command-and-control (C2) server. From there, it gains control over the device, tracking keystrokes, displaying fake overlays, and even initiating remote access.

Crocodilus’ Tactics: How It Steals Crypto

Crocodilus deploys a range of sophisticated tactics to steal digital assets:

• Fake Overlays: The malware uses convincing overlays that mimic wallet apps. It prompts users to enter seed phrases under the guise of a wallet backup requirement, allowing attackers to steal critical information.
• Keylogging: Crocodilus monitors every keystroke, capturing sensitive data such as PINs, passwords, and seed phrases.
• Bypassing 2FA: By recording the screen and controlling the device, the malware can intercept two-factor authentication (2FA) codes from apps like Google Authenticator.
• Remote Access: Crocodilus gains complete control over the device, allowing attackers to open apps, activate the camera, and manipulate texts.

How to Detect and Prevent Crocodilus Attacks

Detecting Crocodilus requires vigilance. Watch for signs like increased battery drain, data usage spikes, and unusual app permissions. To protect against Crocodilus:

• Avoid Suspicious Links: Do not click on unverified links from SMS or email.
• Use Hardware Wallets: Storing assets in hardware wallets limits exposure to malware.
• Check App Permissions: Regularly review permissions for apps with access to sensitive data.
• Stay Updated: Follow credible cybersecurity sources for the latest updates on Crocodilus and other threats.

As Crocodilus continues to evolve, Android users must remain vigilant to protect their digital assets from this stealthy and dangerous malware.
