As the crypto industry continues to evolve under new regulatory and institutional frameworks, 2025 may be remembered equally for its push toward legitimacy and for the vulnerabilities that continue to challenge its foundations.Even as 2025 marked a turning point for the crypto industry with stronger regulation, stablecoin growth, and deeper institutional adoption, it also saw a rise in major hacks and scams that exposed vulnerabilities across decentralised finance (DeFi) and blockchain networks.
“2025 perhaps would go down as a year where you would be looking at vulnerabilities in blockchain protocols, smart contracts and DeFi platforms,” said a market commentator.

One of the biggest incidents involved Abracadabra, a DeFi protocol known for its “Magic Internet Money” stablecoin, which lost about $1.8 million in a flash loan exploit. Another major breach hit Hyper Vault, a yield farming protocol within the Hyper Liquid ecosystem, where $3.6 million was drained in what appeared to be a rug pull.
The Shibarium Bridge also suffered a loss of around $2.4 million, affecting assets like SHIB and Ethereum. In another case, a Bitcoin phishing scam led to the theft of 783 Bitcoins, worth approximately $91 million.
Turkey’s BTC Turk exchange reported a hot wallet exploit, causing losses estimated at $48-50 million. “Nearly 30% of that is just about what has been recovered at this point in time,” the update noted.

Among the other notable cases, GMX V1, a decentralised perpetual trading protocol, saw $40-42 million drained after attackers exploited its smart contract functions. Similarly, Resupply, a DeFi lending platform focused on tokenised donations, lost around $9.5 million.
Finally, Iran’s largest crypto exchange, Nobitex, suffered one of the biggest hits, with about $90 million stolen from its hot wallets.
