According to the 2025 Global Web3 Security Report released by Beosin, the data from the past year is not optimistic. Hacker attacks, phishing scams, and project exits have caused a loss of $3.375 billion in the Web3 ecosystem, spread across 313 major security incidents.

The most severe losses occurred in centralized exchanges (CEX), with thefts totaling $1.765 billion, accounting for over half of the total losses (52.3%). This figure is worth noting—since CEXs are the primary custodians of user assets, security vulnerabilities can have the widest impact once exploited.

In comparison, the DeFi sector, although not necessarily suffering the largest losses, experienced the highest attack frequency, with a total of 91 attack incidents throughout the year. This highlights that smart contract vulnerabilities, flash loan attacks, and similar issues remain long-term security challenges for DeFi.

From a blockchain perspective, Ethereum, due to its rich ecosystem and large amount of funds, has also become a primary target for hackers. Statistics show that there were 170 security incidents on Ethereum, with losses reaching $2.254 billion, accounting for 66.79% of the total Web3 losses for the year—this number vividly reflects how concentrated the risks are.

$3.375 billion... This is our Web3, hard to put into words. CEXs are taking the blame again, major players are all moving to self-custody. One chain of ETH accounts for 66% of the losses, is the concentration really too high? DeFi has been hammered 91 times and still dares to come back? That mental resilience is incredible. Still the same advice: learn to protect yourself before entering the market, don't gamble and go all-in out of frustration.

3.375 billion USD? Oh my god, this number is a bit crazy. CEX has been hacked again with half of the losses, which is why I never leave my coins sleeping on exchanges. Ethereum accounts for 66.79% of the chain? Risk concentration is so outrageous, you really need to diversify. DeFi has been attacked 91 times and is still here, the lightning loan is forever the god. This report is supposed to be shocking, but I just want to ask—it's already 2025, how are people still falling for this?

CEX gets hacked again, and this time the losses are even more severe... How can people still dare to put their coins on exchanges? All the money is being burned on Ethereum, no wonder the ecosystem is getting more competitive, hackers are competing too. DeFi has been attacked 91 times, contract vulnerabilities are truly incredible, do people still dare to play with flash loans? 33.75 billion dollars lost, it feels like this happens every year, are we working for hackers? Ethereum alone accounts for 66% of the losses, how dangerous is this concentration? Exchange run and phishing scams form a one-stop operation, what can you still trust in this industry... It's not that I don't want to play, but these stats are exhausting to look at.

$3.375 billion lost, and we're still here buying coins? Damn, Ethereum alone lost $2.2 billion on one chain, the concentration is just too outrageous. CEX was hacked for $1.7 billion... better to keep your own wallet safe and secure. DeFi losses are smaller, but 91 attacks are really frequent, and flash loans with all those tricks are hard to defend against. Web3 still needs to keep pushing security, or else who will dare to enter the market?

In a loss of $3.375 billion, I bet half of it was caused by self-inflicted mistakes, not hacking. CEX was robbed of $1.765 billion in a year; holding coins in your wallet is still the safest, but then again, who can guarantee no operational errors with self-custody? Ethereum accounts for 66.79% of the chain? This number needs to be carefully considered. With such a high concentration of funds, no wonder it has become a "cash machine." There were 91 DeFi attacks in a year. The flash loan strategy is truly outrageous. I keep hearing people say, "They got drained by flash loans."

Once again, the same set of data. CEXs are being hacked wildly, DeFi is being attacked daily, and Ethereum accounts for 60% of the losses? Basically, all the risks are concentrated in these areas. Who's to blame? Play around, but seeing these numbers still makes me a bit nervous. 3.375 billion just disappeared out of thin air, and I feel like my wallet isn't safe anymore... DeFi has been attacked 91 times yet people still insist on using it. These protocols are really tough, haha. Ethereum is such a vampire—2.254 billion just went into hackers' pockets. When will it finally settle down? So, should we still continue to use CEXs? It feels like being under custody there is worse than death.

3.3 billion dollars lost, is this still called an ecosystem? That's ridiculous. --- Half of the losses from CEX being hacked, I’ve been saying putting coins on exchanges is like gambling with your life. --- Ethereum accounts for 67% of the chain... this concentration is outrageous, it should have been diversified long ago. --- DeFi has been attacked 91 times? Still the same old tricks, smart contract vulnerabilities can never be fully fixed. --- Projects run away, phishing scams... feels like last year's unresolved issues are still being ignored this year. --- Looking at this data, I don’t dare to use CEX anymore, it’s too dangerous. --- 66.79% on Ethereum, this ratio is really frightening. --- No wonder so many people get cut, with such frequent security incidents, who can withstand it?
