Android Spyware Alert: ClayRat and ToSpy Campaigns Explained
Unveiling the Growing Android Spyware Threat: ClayRat, ProSpy, and ToSpy Campaigns
In today’s digital landscape, smartphone security has become more crucial than ever. Android devices, widely used across the globe, have increasingly become prime targets for cybercriminals, particularly through malware and spyware. Among the most dangerous threats are the ClayRat and ToSpy spyware campaigns, which have been detected on Android devices, primarily targeting users in Russia and the UAE. In this article, we will explore these malicious activities and how they are spreading rapidly through fake apps like WhatsApp, TikTok, and Signal.
What is ClayRat? A New Threat to Android Users
The ClayRat malware, discovered by mobile security provider Zimperium, is one of the most alarming Android spyware strains we’ve seen in recent times. This malware spreads primarily through Telegram channels and phishing websites that impersonate popular apps like TikTok, WhatsApp, and YouTube. Once a victim unknowingly installs the malware, their device is turned into a surveillance hub.
ClayRat can spy on SMS messages, call logs, and even take pictures using the phone’s camera. Furthermore, the spyware actively spreads by sending malicious links to every contact in the infected phone’s address book, creating a snowball effect. Over 600 samples of ClayRat have been detected in just the past three months, and the malware is spreading at an alarming rate.
Learn How ClayRat Spreads?
Cybercriminals distribute the malware by directing users to fake websites that mimic official apps. For example, users might visit a counterfeit “YouTube Plus” site that promises additional features. Once on the site, they are instructed to install an APK file, bypassing Android’s built-in security warnings. To increase the chances of installation, these sites often employ fake user reviews and inflated download numbers.
Once installed, ClayRat requests SMS permissions to send malicious links to the victim’s contacts, further spreading the malware without requiring additional infrastructure. It also accesses sensitive information, such as contacts, call logs, and notifications, and may even place phone calls or send SMS messages on behalf of the victim.
ToSpy and ProSpy: Targeting UAE’s Privacy-Conscious Users
While ClayRat is a significant threat globally, spyware campaigns like ToSpy and ProSpy have been particularly active in the United Arab Emirates (UAE). These campaigns target users of messaging apps like Signal and ToTok, which are known for their secure communication features. However, cybercriminals have exploited these trusted apps by distributing malicious versions that appear legitimate but are designed to steal sensitive data.
1. The ProSpy Campaign
The ProSpy campaign has been in operation since 2024, distributing spyware disguised as plugins for Signal and ToTok. These fake updates lure users into manually downloading malicious APK files from phishing websites. Once installed, the spyware collects a wide range of personal data, including SMS messages, contacts, and files from the device’s storage.
Interestingly, ProSpy also targets the .ttkmbackup file extension, which is used by ToTok to store chat history backups. This suggests that the attackers are specifically interested in extracting communication data from users.

2. The ToSpy Campaign
The ToSpy campaign is even more sinister. It impersonates the ToTok app, convincing users to download a fake version. Once installed, the app requests critical permissions to access contacts and device storage. ToSpy then exfiltrates personal data, including contacts, SMS messages, and documents, sending them back to the command-and-control (C&C) server. This malware maintains persistence by running in the background and ensuring continued access to the compromised device.
How ClayRat and Other Spyware Operate: Key Features
Both ClayRat and the ToSpy/ProSpy spyware campaigns share several common characteristics:
- Impersonation of Legitimate Apps: The malware masquerades as popular apps like TikTok, WhatsApp, YouTube, and Signal to gain the victim’s trust.
- Social Engineering: Attackers use fake testimonials and inflated download numbers to lure users into downloading the malicious apps.
- Stealthy Installation: The malware often bypasses Android’s security measures by displaying fake update screens or using droppers that hide the actual payload.
- Data Exfiltration: Once installed, the spyware collects sensitive information, including SMS messages, call logs, contact lists, photos, and device information.
- Propagation: Infected devices automatically send malicious links to contacts, further spreading the malware.
How to Protect Your Android Device from Spyware
While it may seem overwhelming, there are several steps Android users can take to safeguard their devices from malware and spyware attacks:
- Stick to Official App Stores: Always download apps from the Google Play Store, which has built-in security protections, rather than third-party sites that might offer fake APKs.
- Enable Google Play Protect: This feature scans your device for harmful apps and is automatically enabled on most Android devices with Google Play Services.
- Check App Permissions: Be cautious about the permissions requested by apps, especially those that ask for access to your contacts, SMS, or camera. Legitimate apps typically do not require such extensive access.
- Avoid Clicking on Suspicious Links: If you receive a link from an unknown source or a message from a contact that seems unusual, avoid clicking on it. Even if the link appears to come from a trusted source, it may be part of a phishing attempt.
- Keep Your Device Updated: Regularly update your Android device to ensure that you have the latest security patches, which help protect against newly discovered vulnerabilities.
- Use Antivirus Software: Consider installing a reputable mobile antivirus app to add an extra layer of protection against spyware and malware.
Conclusion: Stay Vigilant Against Android Spyware
Android devices are continuously targeted by cybercriminals using increasingly sophisticated malware and spyware, like ClayRat and the ToSpy/ProSpy campaigns. These threats highlight the importance of being cautious about where you download apps and the permissions you grant to them. By following best practices for mobile security, you can reduce the risk of falling victim to these harmful attacks.
