Sentencing and Charges

Ajay Shinjin, also known as AJ Marley Cruz, was sentenced to two-and-a-half years in prison by a UK court for orchestrating a cryptocurrency theft scheme involving SIM-swapping tactics. The fraud resulted in losses exceeding ₹2.56 crore and targeted four victims between November 2021.

Admission of Guilt

Shinjin admitted guilt on September 28 for conspiracy to commit fraud through false representation and transferring illicit assets. The case involved exploiting vulnerabilities in mobile number portability to intercept two-factor authentication codes.

Criminals manipulated telecommunications networks to transfer victims’ phone numbers to SIM cards under their control, enabling unauthorized access to cryptocurrency accounts. This method bypassed security measures reliant on SMS-based verification.

Financial Gains

Shinjin received over ₹56 lakh from stolen funds, which he used to finance luxury travel to Dubai, purchase a high-end residence in London’s Canary Wharf, and acquire gold-plated dental enhancements.

Victims and Losses

The thefts occurred between November 2 and November 7, 2021, with four victims reporting combined losses of ₹2.56 crore. One victim lost approximately ₹51.2 lakh, with ₹34.56 lakh traced to Shinjin’s cryptocurrency wallet. Another suffered a loss of ₹21.76 lakh, while a third lost ₹10.24 lakh from a Coinbase account. The most significant individual loss totaled ₹1.66 crore, reported over November 6 and 7.

Investigation Details

The City of London Police highlighted the complexity of the fraud, emphasizing how SIM-swapping technology enabled the theft of digital assets. The operation relied on telecommunications records, blockchain transaction analysis, and evidence linking Shinjin to devices used in the scheme.

Arrest and Evidence

Shinjin was initially detained in 2021 and later arrested at Heathrow Airport in October 2023 after returning from Dubai. Additional evidence uncovered during the investigation solidified his connection to the crime.

Law Enforcement Statement

Law enforcement officials noted that SIM-swapping represents a growing threat, as it exploits mobile number control to compromise accounts protected by SMS-based authentication. The case underscores the risks associated with relying solely on one-time passwords for securing financial assets.

Conclusion

The case of Ajay Shinjin highlights the increasing sophistication of cybercrime and the critical need for robust security measures beyond SMS-based verification. Authorities continue to emphasize the importance of vigilance in protecting digital assets against evolving threats.
