Indian crypto exchange CoinDCX lost $44 million (₹379 crore) in a sophisticated cyberattack targeting its internal treasury. The breach began with a test transfer and escalated over hours into multiple wallet drains. Bengaluru-based software engineer Rahul Agarwal was arrested after malware on his work laptop—installed via a WhatsApp call from a foreign number—enabled unauthorized access. Authorities suspect a North Korean-linked group, possibly Lazarus. CoinDCX confirmed customer funds are safe and launched a $11 million bounty for fund recovery. The incident underscores growing concerns around insider risks and the need for stronger crypto platform security protocols.
