Cybercriminals Allegedly Used SIM Deactivation to Drain Bank Account

New Delhi | As digital transactions continue to rise rapidly in India, cyber fraud cases are evolving with increasingly sophisticated methods. In the latest incident reported on social media, it has been claimed that cybercriminals managed to siphon off nearly ₹5 lakh from a family’s bank account by disabling their mobile number and disrupting banking alert services.

The case came to light after a post on X (formerly Twitter) detailed how the fraud allegedly unfolded. According to the post, scammers first contacted the telecom service provider while posing as the legitimate mobile user and successfully got the SIM card deactivated. It is alleged that basic identity details linked to Aadhaar were used to bypass verification procedures.

Once the mobile number was deactivated, SMS alerts and OTP-based banking notifications stopped reaching the account holder. Taking advantage of this disruption, the cybercriminals allegedly added a new beneficiary to the bank account and initiated transfers after exploiting the cooling period applicable to newly added payees.

The post claims that within a short span of time, nearly ₹5 lakh was transferred into multiple bank accounts across different regions. The funds were later withdrawn via ATMs, making recovery and tracing of the money extremely difficult.

The victim’s family reportedly stated that they had already informed the telecom company that their phone was not lost or stolen and requested verification through an alternate contact number for any future requests. However, despite this, the SIM was allegedly deactivated again, raising serious concerns about procedural loopholes.

The incident has once again highlighted vulnerabilities in both telecom verification processes and banking security systems. Experts believe that cybercriminals are increasingly relying on social engineering techniques, exploiting human verification processes rather than technical system flaws.

Cybersecurity expert and former IPS officer Professor Triveni Singh noted that modern cyber frauds often target weak points in identity verification and telecom processes. He stated that cybercriminals are increasingly exploiting trust-based systems and procedural gaps. According to him, without real-time integration between telecom operators and banking systems along with multi-layer authentication, preventing such frauds will remain a major challenge.

The viral post also alleges delays in cybercrime response after the complaint was filed, by which time the funds had already been routed through multiple accounts and channels. This delay, it is claimed, significantly reduced the chances of recovery.

The user who shared the incident urged people to enable two-factor authentication (2FA) across all banking and email accounts and to educate elderly family members about emerging cyber fraud techniques. The post also warned that cybercriminals are continuously evolving their methods, where even minor negligence can lead to significant financial losses.

Experts further suggest that OTP-based security alone is no longer sufficient. They emphasize the need for additional verification layers, real-time fraud detection systems, and stronger coordination between telecom and banking institutions to enable instant alerts and prevent unauthorized transactions.

The case has triggered widespread discussion on social media, with users calling for stronger digital banking safeguards. Although the authenticity of the specific incident has not been independently verified, it has once again drawn attention to the growing threat of cyber fraud in the digital economy.

As digital payments become more seamless and widespread, cybercrime techniques are evolving just as rapidly. The incident serves as a reminder that while technology offers convenience, it also demands heightened vigilance and stronger security practices.
