Recently, Vietnamese hackers have been actively targeting Indian users through a sophisticated Android malware campaign, disguised as fake traffic e-challan messages sent via WhatsApp. A dedicated team of researchers has uncovered that this malware, part of the Wromba family, has infected over 4,400 devices, leading to fraudulent transactions exceeding ₹1.6 million. Scammers pose as transportation service or police officials from Karnataka, tricking users into downloading a malicious app designed to steal personal information and intercept OTPs, facilitating financial fraud. The states of Gujarat and Karnataka have been particularly hard hit by these attacks.
Understanding the Threat: The Rise of E-Challan Scams
According to a report by CloudSEK, Indian citizens are increasingly falling victim to new e-challan fraud tactics. The researchers identified that the perpetrators are using WhatsApp as their primary platform to execute this scam. The hackers send out fake traffic e-challan messages, leveraging high-tech Android malware to deceive unsuspecting users.
How Do the Scammers Operate?
Research indicates that these hackers prey on users by posing as either transportation services or Karnataka police. The fake e-challan messages often contain links that appear legitimate, leading potential victims to download malicious APK files unknowingly.
Technical Insights into the Malware
Once the app is installed, the malware gains unauthorized access to critical information such as contacts, phone calls, and SMS messages. It also requests essential permissions that allow it to act as the default messaging app, thereby facilitating the theft of OTPs and other sensitive messages.
Financial Implications of the Malware
The stolen data enables hackers to log into victims’ e-commerce accounts, purchase gift cards, and redeem them with little trace, causing significant financial loss. Reports indicate that over 271 gift cards have been accessed, resulting in transactions amounting to ₹1,631,000, with Gujarat being the most affected state, followed closely by Karnataka.
Tips for Protecting Yourself from Malware Threats
In light of these developments, CloudSEK recommends that users exercise caution and only install apps from trusted sources like the Google Play Store. Additionally, users should:
- Limit app permissions to necessary functions
- Regularly review app permissions
- Keep banking apps and smartphone operating systems updated, including the latest security patches
