The security situation in the crypto world in 2025 is indeed not optimistic. According to the latest security data, the entire Web3 sector has experienced over 1,200 serious security incidents this year, with total losses surpassing $3.5 billion.

In terms of attack types, private key theft (including virus trojans and social engineering), phishing attacks, and fraudulent tokens remain the top three threats. These traditional tactics continue to be effective, highlighting significant room for improvement in user education and prevention awareness.

Even more concerning is the new trend emerging in 2025—the number of high-value thefts is increasing, while the cost of small-scale frauds has significantly decreased. In other words, attackers are adopting a dual strategy of "precision hunting" and "broad net casting," targeting both big fish and small retail investors.

Looking at some of the most severe incidents illustrates how outrageous the situation is: a leading exchange was hacked in February with losses of up to $1.5 billion; a well-known protocol was hacked in May with losses of $223 million; a DEX was hacked again in November with losses of $128 million. These three incidents alone account for a significant portion of the industry's total losses.

It is particularly important to note that there were 12 major cases with losses exceeding $30 million throughout the year, of which 7 involved CeFi platforms. The main causes were attributed to administrator private key theft and hot wallet private key leaks. This exposes a significant risk gap in centralized exchanges' private key management.

Overall, the security landscape of Web3 in 2025 is characterized by "frequent major incidents and rampant small scams," and all users need to remain vigilant.

I have received the article content. I will generate 5 natural and credible comments in the style of "Community Incubator." --- 3.5 billion USD... This number is really unsustainable, it feels like every month is a爆雷 month If you ask me, those exchanges' private key management is just like not managing at all, they should have been liquidated long ago Small investors are used to being cut, now even big players are starting to fall behind, this industry is really unpredictable 1200 incidents? I just want to know if anyone has really been arrested, or if they just drifted away so easily Phishing scams really should be banned, but it’s impossible to ban because people are greedy

This data is quite brutal, $3.5 billion just gone like that. Private key leaks are still happening, which shows everyone really needs to wake up. Small retail investors shouldn't relax too much either; precise hunting combined with broad net casting—no one is safe. Seven major cases on CeFi platforms? The management level of centralized exchanges is really... How was that $1.5 billion stolen? I really want to know. It's not the first year, so why are people still falling for phishing attacks? Every year, they say user education needs to be improved; every year, it's the same old story. That's why I don't dare to put anything on exchanges now. Wood custody solutions are at least better than just going naked.

3.5 billion USD, this number sounds outrageous, better to use cold wallets properly. --- Private keys are really a matter of life and death; too many people are careless. --- Once again, CeFi gets hit. Centralized platform private key management really needs reflection. --- Casting a wide net for precise hunting? Attackers have also learned to operate meticulously, incredible. --- Once for 1.5 billion USD? My goodness, if it were small investors, they would have gone bankrupt long ago. --- Honestly, despite these incidents, users still don't learn their lesson; there's a big gap in education. --- A dual strategy, both targeting big and small investors, it seems no one can escape. --- Looking at this data makes me want to freeze all coins in cold wallets and do nothing. --- Over 1200 incidents... this is the Web3 ecosystem in 2025, it's a bit overwhelming. --- Hot wallet leaks are too common; who still dares to keep large amounts on exchanges?

3.5 billion USD lost, I really can't take it anymore --- It's the same old trick with private keys, how come they just can't learn? --- Should small retail investors be cut? The game rules are truly pathological --- 150 million in one transaction, how big of a vulnerability is needed for this to happen? --- CeFi folks really should reflect on their risk control levels --- Double strategy sounds good, but honestly, it's just about biting whoever is caught --- Hearing about 1200+ incidents makes my scalp tingle, we're just gambling here --- Phishing can't be prevented, people get caught every day --- Frequent major cases and small scams are truly a disaster, this description is very fitting --- Private key leaks should be directly exposed with the exchange names, no more hiding and covering up

$3.5 billion gone, and we're still playing around? --- Exchanges can't even keep their private keys safe, who’s to blame? --- Small retail investors should just accept their fate, right? This world is too crazy. --- $1.5 billion lost in one go, it feels like it's not far from us. --- Once again, private key leaks. CeFi is truly a ticking time bomb. --- Phishing attacks are still so rampant; how stupid are we? --- Big whales are targeted, small retail investors get cut, no one is safe. --- Over 1,200 incidents, $3.5 billion lost—does this number seem outrageous or not? --- When CeFi administrators' private keys fail, we're doomed. --- It's 2025, and we're still using traditional tricks? Attackers are way smarter than us.

$3.5 billion directly evaporated, this number still sounds a bit scary. The old tricks with private keys are still being tried and tested, which shows everyone really needs to wake up. Small retail investors are being repeatedly harvested, and even hot wallets of major exchanges can't be sealed off. These days, no one can run away. Human weakness, a breeding ground for hackers, just like that. CeFi big players who can't even manage their private keys dare to call themselves professionals? Laughable. Instead of just reading reports, it's better to pay attention yourself; there is no such thing as absolute security in the world.
