August 2025 shook the crypto market with significant security breaches. A total of 16 major hack caused $163 million in losses, marking a 15% increase compared to July. The attacks targeted exchanges, individual investors, and RWA tokenization projects. No segment of the chain appeared fully secure.
Major Crypto Hack and Losses in August 2025
Hackers struck a Bitcoin holder, stealing approximately $91.4 million. BtcTurk lost between $48–54 million from its hot wallets. ODIN•FUN suffered $7 million, BetterBank.io lost $5 million, and CrediXFinance experienced $4.5 million in losses. These figures highlight risks from weak private key management, smart contract vulnerabilities, and operational weaknesses in exchanges.
Organized hacking groups remained active in August. Reports indicate alleged North Korean hackers stole around $1.6 billion in crypto during the first half of 2025, accounting for roughly 70% of global losses. Moreover, social engineering attacks allowed hackers to infiltrate internal systems. By applying for IT jobs with fake identities, they accessed corporate systems and software supply chains.
RWA Projects and Rising Security Risks
Real World Asset (RWA) tokenization projects also faced increasing attacks. Certik reports indicate $14.6 million in losses during the first half of 2025. RWA projects combine on-chain infrastructure with off-chain assets, creating multiple weak points for exploitation. This combination of technical and human-based risks provides attackers significant opportunities.
Rising attacks emphasize the need for stronger security measures. Audits, red team tests, and insurance coverage have become critical. Additionally, strict internal controls are essential to prevent insider threats. By improving these measures, exchanges and investors can better defend against evolving attack patterns.
August 2025 demonstrated the crucial importance of a robust security culture in the crypto ecosystem. Both individual investors and institutions must strengthen their systems. Every segment of the chain remains exposed to potential losses, and this trend is likely to continue in the coming months.
