Blockchain security in 2025 is under pressure: 200 incidents, $2.9 billion in losses, with vulnerabilities in both DeFi and exchanges

2025-12-30 09:42:12

【ChainNews】The blockchain industry in 2025 has not been peaceful. Throughout the year, security incidents occurred frequently—more than 200 in total. The total losses amount to $2.935 billion, a 46% increase compared to 2024. It’s truly exhausting.

Let’s take a closer look at which sectors were most affected. DeFi projects suffered 126 attacks, the highest number of incidents, but the losses were about $649 million. In comparison, trading platforms were hit much harder—they experienced only 12 incidents but lost $1.809 billion. One major exchange was hacked for a single amount of $1.46 billion, becoming the biggest black swan of the year.

How do hackers attack? Mainly two methods: one is targeting smart contract vulnerabilities (61 incidents), and the other is compromising social media accounts (48 incidents). Hackers are becoming increasingly professionalized, with RaaS/MaaS models lowering the barrier to entry, making it very easy to get into the industry. Coupled with Southeast Asian scams as upstream activities and privacy mixing tools for money laundering in the final mile, the entire industry chain has taken shape.

The good news is that regulators are taking action. Many countries are accelerating AML/CFT compliance efforts through freezing accounts, economic sanctions, and cross-border joint law enforcement, significantly improving on-chain tracking and asset freezing efficiency. This puts real pressure on hackers.

1. 1.46 billion directly evaporated, who can withstand this? --- DeFi was hammered 126 times and still hasn't completely collapsed, this resilience is indeed outrageous. --- Contract vulnerabilities + social engineering, hackers are really just clocking in for work now. --- RaaS model lowers the threshold for black market activities, this is the real problem. --- An incident on an exchange can wipe out a year's worth of DeFi losses, which is a bit ironic. --- 29.35 billion is not too much or too little, but the 46% surge in growth is truly frightening. --- Why do major exchanges always have issues? Are security teams dozing off? --- Social media accounts have been hacked 48 times, this really underestimates people's greed.

14.6 billion is gone, how long do I need to save to earn a month's salary? --- DeFi was hammered 126 times for only 600 million, while exchanges were hit 12 times for a direct 1.8 billion. The gap... is outrageous. --- Contract vulnerabilities + social accounts—hackers have really learned to be clever. --- 3 billion USD... I’ve never seen such a large number in all my life, feeling a bit hopeless. --- RaaS lowering the barrier to entry is the most terrifying thing; hackers have industrialized. --- A major exchange might not even be able to cover this hole with a month's profit. --- Feels more chaotic than 2024; this industry really isn’t fun to play with anymore.

Did an exchange get hacked for 1.46 billion at once? How terrible is their risk control, it's hilarious --- Contract vulnerabilities, social media accounts… Hackers really turned into a production line, this industry is truly unbelievable --- Lost $2.9 billion, my principal is right there --- DeFi was attacked 126 times, losing only 649 million; exchanges 12 times, directly 1.8 billion? The math doesn't add up --- RaaS model is basically hacker franchise stores, who would have thought this thing is really a genius --- Again, top-tier exchanges, no one can match in security --- Southeast Asia scams upstream, hacker specialization… the entire ecosystem is rotten through --- 46% surge? It was already bad enough last year, this year is even worse --- I was still hoping DeFi could turn around, but seeing these numbers just made me lose it --- A single theft of 1.46 billion, hilarious. Did this exchange write the private key on a note?

The $1.46 billion single theft on the exchange is unsustainable. Who can handle this? --- 61 contract vulnerabilities, honestly, it's still the developers' rush, audits can't keep up. --- The RaaS model has really lowered the barrier to hacking to the floor, it's outrageous. --- DeFi has been attacked 126 times, losing only $650 million; exchanges were attacked 12 times, losing $1.8 billion. These numbers look unbelievable. --- 48 social media accounts have been attacked? It's really time to enforce hardware wallets, everyone. --- $2.935 billion surged by 46%, 2025 is truly a nightmare year for security. --- The scam chains in Southeast Asia are so deep that ordinary people can't avoid them at all. --- The professionalization of hacker organizations has become a fact; the era of solo operations is completely over.

Exchanges lose 1.46 billion annually, how outrageous is that? --- DeFi has been attacked 126 times yet still survives, while exchanges have been drained 12 times directly. Such a huge gap? --- Contract vulnerabilities, social engineering, RaaS models—hackers are now really working on an assembly line. --- $2.9 billion in losses, a 46% increase... Could your wallet be next? --- Only exchanges dare to play like this. DeFi with 126 incidents has paid out over 600 million, while 12 incidents have cost 1.8 billion. --- The cost for hackers to get started is so low, why are people still willing to put their coins in exchanges? --- The blockchain in 2025 is truly a thriller. I have to check my assets every night before bed.

$1.46 billion stolen in one go? The security of this exchange is truly top-notch, even more outrageous than DeFi --- Contract vulnerabilities and social media accounts combined—hackers are now practically operating on an industrial scale --- $2.9 billion gone, our small amount of funds is like mosquito bites; it’s heartbreaking for those big investors --- RaaS model really lowers the barrier to committing crimes, it's outrageous --- The number of incidents has surged by 46%, just looking at these numbers makes your scalp tingle—dare to engage with DeFi? --- A leading exchange's single incident involved $1.46 billion—how outrageous is that? Are security audits just for show? --- Hackers are becoming increasingly professional; it feels like ordinary people simply can't defend against them --- 12 exchange incidents have resulted in a loss of $1.8 billion—if you calculate the probability, each case is astronomical
