2025 Web3 Security Crisis: The Truth Behind 1,200+ Incidents and $3.5 Billion in Losses

2025-12-29 14:20:10

【Crypto World】How severe will the Web3 security situation be in 2025? According to the latest data, more than 1,200 significant security incidents occurred that year, resulting in total losses exceeding $3.5 billion.

The risk points are mainly concentrated in several areas. The theft of hot wallets and private keys on CeFi platforms is the top threat—these centralized exchanges remain the primary targets for hackers. Although losses caused by smart contract vulnerabilities in DeFi are decreasing, the problems are becoming more complex: deep logical flaws in Move contracts are beginning to surface, becoming new hidden dangers.

The specific high-frequency attack types include private key theft, phishing attacks, and Rug Token scams. Looking at affected projects, the annual losses of a certain leading exchange, a mainstream DEX protocol, and platforms like Balancer in 2025 are quite substantial.

This set of data serves as a reminder to all Web3 participants: whether you are crypto enthusiasts or project teams, security awareness must be upgraded. Isolating hot wallets, multi-signature wallets, and cautious interaction with unfamiliar contracts—these age-old recommendations are now more important than ever.

35 billion dollars, how many people have been scammed... I think the key is to keep your private keys safe yourself. --- Move contract vulnerability? This is a new trap again, feeling like security is becoming more and more difficult. --- CeFi is still being targeted by hackers, no wonder I still prefer self-custody. --- Over 1200 incidents, averaging more than 3 per day, this number is a bit outrageous. --- Phishing is the most disgusting part, hard to prevent, sometimes you accidentally click on it. --- Rug Token scams are still happening? Be cautious with those new tokens, don’t rush into it. --- Nowadays, doing on-chain activities without relying on yourself is too risky. It’s better to have a hardware wallet for peace of mind. --- Top exchanges are all being hacked, so we small retail investors have to be on alert at all times.

Is $3.5 billion just like that? Feels like the CeFi crew is just passing the buck to hackers again --- Private key theft is still the top issue, which shows how many people are still using exchange wallets... Truly speechless --- Move contract vulnerability? Now there's a new task to do, the repair engineers are going to be busy --- Rug Token incidents happen every year, why are there still so many people bottom-fishing? --- 1200 incidents with a total loss of $3.5 billion, averaging only $3 million per case. This data seems to be skewed by small cases --- Phishing attacks account for such a large proportion, indicating that education hasn't kept up, brothers --- Certain leading exchanges, certain mainstream DEXs, how much can "certain" hide? Just say it directly --- DeFi vulnerabilities are decreasing... probably because everyone has moved to CeFi, haha --- Looking at this trend, by 2025, a new batch of white-hat heroes will emerge in the security circle --- Fortunately, I didn't invest any money this year, or I would have become part of the statistics

3.5 billion dollars lost, and that's just the official statistics... I think the actual number might be double Phishing is really top-notch, I have friends who have fallen for it again, everyone needs to wake up Hot wallet thefts are stuck in a vicious cycle, CeFi can’t be trusted, self-custody is the way to go Move contract, this new trap... forget it, I won’t touch this stuff anymore, too dangerous Rug tokens are everywhere, you need to train your eyes to the point of glowing The 1200+ incidents sound scary, but I feel like this is just the tip of the iceberg Forget safety for now, I just want to know who hasn’t been hacked... Balancer got caught again? How are these old projects still making such mistakes

honestly, 35B in losses is just mile 20 of this marathon... but like, that's when most sprinters quit. the real question is whether we're learning or just repeating the same private key mistakes every cycle.

$3.5 billion lost in the blink of an eye. These days, even DEXs are starting to fail. Who still dares to say their private keys are truly secure? --- Over 1200 incidents... I’ve always said that centralized exchanges are just honey pots. Retail investors are still holding coins there. --- New vulnerability in Move contracts? Here comes another wave of exploitation. Who can see through this layered risk? --- Phishing + Rug pulls, old tricks with new twists. This game is even more dangerous than the NFT market. --- Looks like my earlier decision to bet on DeFi was a bit hasty. On-chain data is right here; no one can run from it. --- Balancer has been called out. Even top projects can't withstand it, let alone the underlying users. --- Isn't this exactly the real picture I described during the bottoming phase last year? The market sentiment hasn't settled, and yet another blow comes. --- Over 1200 incidents... It seems the official data has been understated; the reality might be even worse. --- Hot wallet thefts are the top threat? Honestly, it’s a common problem with centralized platforms. Decentralization isn’t that simple either. --- Follow the trend downward? I just want to know who else will keep pouring money in.

$3.5 billion is gone just like that, and I’m still here debating whether to add to my position, hilarious. Private key theft is still the number one killer. How many times do I have to say don’t connect to the internet, everyone? Move contract issues again? Let me check if there’s any risk in my positions... Phishing is truly hard to prevent. Recently, I’ve seen a few "official" wallet tricks again, terrifying. 1200 incidents, $3.5 billion in losses—these numbers mean I had to sleep less last year. Rug Token scams are still rampant? I just want to know what the victims are thinking. Balancer also got caught in a trap. It feels like no platform is truly safe. Hot wallets aren’t sitting ducks, when will the exchanges learn their lesson? No wonder so many people are asking "how to be safe" lately—this is indeed worrying. What to do? Now even DeFi can’t be trusted, let alone CeFi.

$3.5 billion gone, still waiting for a rebound to buy in? Wake up, everyone. What do the incidents starting from 1200 indicate... the market bottom is still far away. That group of CeFi people will never learn; they just can't manage private keys properly. It's the same script every year. The true trading wisdom is... buy more after a decline, don't try to catch the bottom. This wave of reshuffling has just begun, and it will get even worse. Rug Token scams still attract people; it's a weakness of human nature. Let's wait and see. Past experience tells me there are always lower points.
