eSIM (Embedded SIM) is a digital SIM installed in smartphones through software, providing all the functionalities of a physical SIM, including calls, messages, and internet data. However, cybercriminals have begun to misuse this modern technology. If a hacker converts your physical SIM into an eSIM without your knowledge, they can gain access to your bank's OTP and authentication codes, potentially giving them complete control over your bank account.
Big eSIM Fraud in Mumbai
Recently, a person in Mumbai fell victim to eSIM fraud. The victim received a call from an unknown number, and within just 15 minutes, his phone's network was shut down. By the time he managed to block his ATM card, UPI, and bank account, Rs 4 lakh had already been withdrawn from his account. Investigations revealed that the criminals had sent a link to the victim, which he inadvertently clicked. This action allowed the hackers to convert his SIM into an eSIM, placing it directly under their control.
How Does This Scam Work?
When a physical SIM is converted into an eSIM, the fraudster’s device begins receiving all the victim's calls and OTPs. Unlike traditional SIM swaps, where only SMS messages are affected, eSIM fraud allows OTPs to be delivered through calls as well. This accelerates the fraud and makes detection more challenging.
Tips to Avoid eSIM Fraud
Do not click on any suspicious links, whether received via SMS, email, or social media.
Do not provide any personal information to unknown callers claiming to verify your SIM or eSIM.
Never share banking or personal details through phone calls, messages, or emails.
Whenever possible, enable multi-factor authentication (MFA).
If your phone network suddenly disappears, immediately contact your telecom operator and bank.
Experts' Warning
Cybersecurity experts caution that while eSIM technology is inherently safe, user carelessness can make it vulnerable. They say that the best defense is to remain vigilant and take immediate action against any suspicious activity.
