Hyderabad: After a man in Delhi was duped and robbed of over Rs 50 lakh by some unknown fraudsters through a series of missed calls, even without sharing any one-time password (OTP) or personal details with the accused, the Hyderabad city police warned residents to be wary of SIM – the switching technique.
In SIM swap fraud, criminals gain access to a victim’s phone through fake emails (phishing), fake phone calls (vishing), fake text messages (smishing), etc. They then use personal information to create a fake identification, impersonate to be the victim, and tricked the telecom service provider into issuing a duplicate SIM card. When the duplicate SIM card starts working, the original SIM card will be blocked.
Using the duplicate SIM card, the fraudster can obtain an OTP and other notifications required to complete financial transactions through the victim’s bank account.
Police in the city asked people to contact their service provider immediately if they believe their SIM card has been switched.
Some early warning signs of SIM switch attacks:
Your device will start working once you have been hit by a SIM swapping attack. You cannot send or receive text messages and phone calls. You will suddenly be logged out of all your applications and various other accounts and unable to log back in. Your social media accounts or email may be hacked.
If you have the appropriate settings enabled, you may receive alerts or email alerts that your service provider profile information and other accounts have changed or that logins were made from unknown locations or devices.
In some cases, you will receive notifications from your provider that your phone number or SIM card has been activated elsewhere. Your financial institutions will send fraud alerts or suspicious activity.
How to prevent SIM switching?
It is mandatory to set up two-factor authentication using authenticator apps. Never click on links in suspicious messages. Your browser will usually ask you if you want the websites you visit to remember your password or even debit or credit card information. It’s better if you always say no and don’t set up autofill as a shortcut.
