Last night, while you were asleep, your money may have been carried off
AFX Trade cross-chain bridge: 24.15 million USDC drained
B² Network: 8.59 million B2 tokens taken away
Balance Coin, an algorithmic stablecoin: crashes 99%, nominal market cap nearly zero
Three protocols, three attack methods, the same night
Cross-chain bridges, token contracts, oracles—DeFi’s three main weak points—all fell on the same night
This isn’t a coincidence. This is a full-scale stress test. And the results? The entire DeFi security perimeter is riddled with holes
AFX Trade: let 24 million dollars go with just 5 signatures
First, take a look at the first one
AFX Trade, a derivatives exchange on Arbitrum, with USDC settlement, up to 100x leverage
Then last night at 21:30, Blockaid detected abnormal activity
The attacker compromised the cross-chain bridge’s validator signature key
With 5 validator signatures—enough to reach two-thirds of the voting power—a withdrawal of 24.15 million USDC was approved normally
A 200-second dispute window—no one noticed, no one stopped it
Then what? Funds moved from Arbitrum to Ethereum at an average price of 1937 dollars, buying 12,467 ETH in one go
B² Network: 8.59 million tokens, 15% instantly evaporated
Next, look at the second one
On BNB Chain, B² Network had 8.591 million B2 tokens stolen, worth about 3.86 million dollars
The attacker swapped these tokens for 5,409 WBNB, bridged to Ethereum, and then transferred into Zcash via the NEAR Intents bridge
Zcash. A privacy coin
This means the money may never be recoverable
What did the B² team do? They posted an on-chain message to the attacker:
“Return at least 10% within 24 hours. We won’t initiate legal proceedings.”
When I read this, I laughed
3.86 million dollars—so you just ask them to give back 380k and call it done?
Balance Coin: a mispriced asset—market cap of 3.5 million wiped to zero
Last one, the most outrageous
Algorithmic stablecoin Balance Coin, running on BNB Chain, pegged to 1 dollar
What did the attacker do? They manipulated the protocol’s price oracle, writing an abnormally low Bitcoin price into the system
That’s it. One wrong price
The lending contract had no reasonable range checks and no liquidation delay mechanism. With a single transaction, the attacker instantly liquidated Bitcoin collateral that should not have been liquidated
Balance Coin went from near 1 dollar straight down to 0.0014 dollars
The attacker netted 912,000 dollars
One oracle bug, and a stablecoin basically dies
Tell me, is this “decentralized finance”? This is “financial LEGO”? It’s a house of cards
Three attacks in one night—different attack surfaces:
Cross-chain bridge: validator signature key was controlled
Token contract: tokens siphoned directly
Oracle: price manipulation triggers cascading liquidations
DeFi’s three main weak points—stabbed all on the same night
And this is only the tip of the iceberg
From July to now, there have been at least 14 crypto security incidents, with monthly losses approaching 97 million dollars
Even scarier is what’s happening offline
A report just released by CertiK shows: in the first half of 2026, there were 52 globally publicly verified “wrench attacks,” with losses of 124 million dollars—up 11.8x year over year
Home invasions jumped from 1 case in the first half of last year to 20 cases
Attackers have shifted from technical vulnerabilities to personal threats
No matter how safe your cold wallet is, can it withstand someone using a wrench to pry open your door?
When these three projects were attacked last night, most people were asleep
By the time you wake up, the money is gone, the tokens are worthless, and the team will only issue one line: “Under investigation”
What’s the most brutal thing about this industry?
You study candlestick charts, fundamentals, and the track—but hackers only need to study one contract vulnerability
Your return is 10% annualized; the hacker’s return is 24 million dollars in one night
You think you’re investing, but you’re actually working for the hacker.
