CoinDCX Software Engineer Arrested in Connection to $44 Million Hack
A staff member at CoinDCX, a prominent Indian cryptocurrency exchange, faces arrest following a major security breach. Bengaluru authorities took Rahul Agarwal into custody linked to a ₹379-crore ($44 million) theft of funds.
The matter came to light after Nebilo Technologies, which operates CoinDCX, reported unauthorized access to their systems. Hardeep Singh, the company’s Vice President for Public Policy, explained that the breach occurred on July 19. The attackers transferred 1 USDT to an external wallet around 2:30 a.m., and by 9:30 a.m., they had siphoned off millions of dollars.
During police interrogation, Agarwal insisted on his innocence. Yet, he admitted to “moonlighting” with external parties. Investigators found that he received ₹15 lakh (~$17,000) from an unknown source, raising suspicions about his activities. Additionally, Agarwal mentioned receiving a suspicious phone call from a German number, which he believes led to malware infiltrating CoinDCX’s systems.
The attack itself has been characterized as a “sophisticated social engineering attack” by CoinDCX’s CEO, Sumit Gupta. He revealed the incident on social media but could not provide further details, citing an ongoing investigation.
Crypto exchanges increasingly face security threats, with this breach marking another significant loss in a year filled with costly hacks. For instance, the February hack on Bybit saw losses of $1.5 billion, attributed to the notorious North Korean Lazarus Group. Such incidents spotlight the rapidly evolving landscape of cybersecurity threats in the cryptocurrency realm.
Experts note that the surge in attacks underscores the urgent need for enhanced measures to protect digital assets. As the stakes grow higher, technology development must prioritize security innovations to safeguard both companies and users in an ever-changing landscape.
