- WhatsApp scam targets Android users with fake e-challan messages containing malware.
- Vietnamese hackers use Maorrisbot malware to access contacts, messages, and e-commerce accounts.
- Over 4,451 devices compromised, resulting in Rs. 16 lakh theft through 271 gift cards.
In recent times, a sophisticated scam has been sweeping across India, targeting WhatsApp users. This scam, primarily affecting Android users, involves the distribution of fake e-challan messages that contain malicious software. These fraudulent messages are designed to trick recipients into downloading malware, which then infiltrates their devices and compromises personal information.
Cybersecurity firm CloudSEK has shed light on this concerning trend, revealing that the culprits behind these attacks are hackers based in Vietnam. These cybercriminals have devised an elaborate scheme to deceive users and steal sensitive information, causing significant financial losses for many.
WhatsApp Scam Unveiled
The scam operates by sending fake traffic e-challan messages to users. These messages often impersonate official agencies like Parivahan Sewa or the Karnataka Police, urging recipients to pay fines for alleged traffic violations. The message includes a link or an APK file, which, when clicked or downloaded, installs Maorrisbot malware on the victim’s device. This malware is adept at disguising itself as a legitimate application, making it difficult for users to detect the threat.
Once installed, Maorrisbot malware requests various permissions, such as access to contacts, phone calls, SMS, and default messaging app status. If granted, the malware gains the ability to intercept one-time passwords (OTPs) and other sensitive messages. This enables the hackers to access the victim’s e-commerce accounts, purchase gift cards, and redeem them without detection.
WhatsApp e-Challan Scam
According to CloudSEK, the WhatsApp e-challan scam has led to the compromise of 4,451 devices, resulting in the theft of over Rs. 16 lakh through the unauthorized use of 271 unique gift cards. The most affected regions in India include Gujarat and Karnataka.
Vietnamese hackers are behind this scam, using highly technical methods to execute their attacks. The investigation by CloudSEK traced the hacker’s IP address to Bắc Giang Province in Vietnam. These scammers use proxy IPs and maintain low transaction profiles to avoid detection, making it challenging for authorities to track their activities.
Maorrisbot Malware in Detail
Maorrisbot malware, the primary tool used in these attacks, is a sophisticated piece of software capable of significant damage. Once installed on a device, it not only intercepts OTPs but also accesses the user’s contact list, phone calls, and messages. This allows the malware to perform unauthorized transactions, such as purchasing gift cards from e-commerce accounts linked to the victim’s phone.
The malware can remain hidden on the device, making it difficult for users to detect its presence. CloudSEK reports that 4,451 mobile users have fallen victim to this scam, with the hackers purchasing 271 gift cards and causing financial losses exceeding Rs. 16 lakh.
Protecting Yourself from the WhatsApp Scam
To safeguard against this scam, CloudSEK recommends several precautions for Android users:
- Use reputable antivirus and anti-malware software: Ensure your device is protected by installing well-known security applications.
- Limit app permissions: Regularly review and limit the permissions granted to apps on your device.
- Install apps from trusted sources only: Avoid downloading and installing apps from unknown or untrusted sources.
- Monitor for suspicious SMS activity: Be vigilant about unexpected or suspicious messages and links.
- Regularly update your device: Keep your device’s software up-to-date to protect against the latest threats.
- Enable alerts for banking and sensitive services: Set up notifications to monitor activities related to banking and other sensitive accounts.
By following these recommendations, users can reduce the risk of falling victim to such scams and protect their devices and personal information from being compromised.
Conclusion
The WhatsApp scam, driven by Vietnamese hackers, has highlighted the importance of cybersecurity awareness and vigilance. Android users must remain cautious and take proactive measures to protect themselves from such sophisticated attacks.
