Top 7 Hidden Risks of SMS OTP Authentication
SIM Swap Attacks
Criminals can trick mobile carriers into transferring a victim’s phone number to a new SIM card. Once done, the attacker receives all the OTP messages and gains access to accounts. This method is surprisingly common and hard to detect until damage is done.SMS Interception
SMS messages travel over the cellular network unencrypted. Hackers can intercept these messages using specialized equipment or malware, especially on older 2G networks that lack strong encryption.Malware on Mobile Devices
If someone’s phone is infected with malware, it can automatically read incoming SMS messages and send OTP codes to attackers without the user knowing.Social Engineering Attacks
Attackers can impersonate users or customer support to trick mobile carriers or companies into revealing OTP codes or resetting passwords.Delayed or Failed Delivery
Sometimes OTP messages gets delayed or don’t arrive at all due to network issues. This can lock users out of their own accounts or cause frustration, reducing trust in the security system.Phone Number Recycling
Mobile carriers recycle phone numbers after a number’s been inactive for some time. A new owner of that number could potentially receive OTPs intended for the previous user and access their accounts.Limited Security Scope
SMS OTP only verifies possession of the phone, not the user’s identity. If someone steals your phone, they can receive OTPs and bypass this security measure easily.
