Two men, a 50-year-old from Begum Bazar and a 43-year-old from Gaddiannaram, lost ₹5,08,799 and ₹1,00,500 respectively in September after fraudsters tricked them into installing a malicious mobile application named RTO Challan.APK.Once installed, the app gave criminals remote access to their phones, enabling unauthorised debit transactions from their Central Bank of India and IndusInd Bank accounts, warned an officer from the Hyderabad cyber crimes police. The victims immediately blocked their accounts, alerted the 1930 cyber helpline and lodged complaints with the Cyber Crime Police Station. Investigators said the fraudsters exploited stolen OTPs and banking credentials to siphon off money.Police have warned the public against downloading suspicious APK files such as RTO Challan APK, PM Kisan APK or Court Order RTO APK, which are being circulated via SMS, WhatsApp, Telegram and social media.
