Notably, five major hacks were behind most of the crypto losses in July. 

The largest hit came from CoinDCX, which lost $44.2 million. An employee at CoinDCX was recently arrested after the hack. As per the local reports, Rahul Agarwal, a software engineer, was detained by Bengaluru police after hackers allegedly used his login credentials to access company servers and steal funds. 

CoinDCX CEO Sumit Gupta said that this appears to be a “sophisticated social engineering attack,” where employees are increasingly being targeted to gain access to the systems.

While rare, this kind of reversal has sparked debate over hacker motives and negotiation strategies in the DeFi world.
