In crypto shadow the usual story is simple: once money’s gone it’s gone. Hackers slip stolen funds through mixers scatter them across blockchains, or launder them so thoroughly the trail goes cold. You almost never see those coins come back. But every now and then, things play out differently.
On February 19, 2026, South Korean prosecutors made a surprise announcement. They got back about 320.8 BTC worth $21.4 million at the time, with Bitcoin trading between $66,000 and $68,000. The hacker didn’t return the money out of guilt. Enforcement cornered them, cut off every way out, and the attacker still anonymous had nowhere else to go.

This all started with a fiasco in 2025. The Gwangju District Prosecutors’ Office had been holding Bitcoin seized from previous criminal cases, mostly illegal gambling. In August, during what should’ve been a routine check of their wallets, the funds vanished.
Turns out, it was a phishing attack. Someone tricked officials into using a fake interface or giving up sensitive info. Within minutes, about 320 BTC disappeared from dozens of wallets. Even government agencies, it turns out, are just as vulnerable to social engineering as anyone else.
The theft set off a wave of public criticism and internal audits. These weren’t new coins they were evidence, scattered across 57 hardware wallets. The breach exposed some glaring problems: not enough verification, too many people with access, and the bigger issue institutions handling crypto without proper custodial infrastructure are sitting ducks.

By early 2026, prosecutors went from panic mode to strategy. They used advanced blockchain analytics and exchange compliance laws like mandatory ID checks and quick asset freezes to chase down the stolen Bitcoin. They never caught the hacker, but they managed something almost as good: they made the coins nearly impossible to cash out.
Authorities flagged every wallet involved and worked with centralized exchanges to shut the doors. No compliant exchange would touch those coins. Suddenly, turning $21 million in Bitcoin into real-world cash became a nightmare.
Boxed in and out of options, the hacker sent all 320.8 BTC straight back to the prosecutors on February 19. No deals no talks. Pure enforcement muscle.
But there was a twist. Within hours of the funds coming home the Bitcoin moved again, this time to a new set of addresses. Maybe internal wallet shuffling, maybe security upgrades no one knows for sure. What matters is the rarest outcome in crypto crime: the funds made it back.

Why does this actually matter?
Because it’s about more than one country or one hack. Strong regulatory frameworks and coordinated compliance can reshape how crypto crime works.
When stolen coins get recovered instead of dumped on the market, you avoid sudden sell-offs that could rattle already shaky markets.
If you can’t get your loot onto a compliant exchange, stealing traceable assets like Bitcoin gets a lot less attractive.
Institutions, take note phishing isn’t going away. Multi-sig wallets, tight access controls, real verification, and air-gapped security aren’t extra steps anymore. They’re the basics.
And for Bitcoin itself, this helps. Treating crypto as recoverable property, not just lost forever if stolen, gives it more legitimacy and builds confidence in the system.
Is $21 million a huge sum?
Not compared to the multi-billion-dollar hacks we’ve seen. But the rarity is the story. In an industry famous for irreversible mistakes, getting stolen funds back almost feels like magic.
As Bitcoin hovers in the mid-$60,000s and markets feel uncertain, stories like this quietly chip away at the usual fear and skepticism. Hacks still grab headlines, but this case is proof: with smart enforcement and the right tools, sometimes you really can change the ending.
In crypto, reversals don’t come often. That’s what makes this one matter.

Author of the news: Crypto Emergency
A sharp decline in fees on the Ethereum network after the December Fusaka update has led not only to an increase in activity but also to a new wave of fraudulent attacks. Experts link the record number of transactions not to organic growth in network usage but to the activation of criminals, for whom it has become significantly cheaper to conduct mass spam operations.

Quantum computing advances are exciting, and the Bitcoin community is showing its legendary foresight by addressing long-term cryptographic considerations early. Experts stress the threat is not imminent — it’s an engineering challenge that will be solved, with fault-tolerant machines still years away.
Post-quantum signature schemes already exist. Developers are exploring gradual, backward-compatible upgrades (new address formats, soft forks, voluntary migrations) just like the hugely successful SegWit and Taproot rollouts. Teams are also working on signature aggregation to keep transaction sizes efficient.
Only addresses that have reused public keys face potential future exposure, while Bitcoin’s SHA-256 Proof-of-Work remains highly resistant. Leaders like Adam Back remind us there is still ample time for deliberate, thoughtful preparation.
This proactive stance proves once again why Bitcoin is antifragile. Our decentralized coordination and innovation culture keep it the most secure asset on the planet — today and for generations to come.

A proposal was implemented on Moonwell (DeFi on Base).
In just 4 minutes...
Loss ≈ $1.8 million.

⚡ What happened?
The code — which was generated/assisted by Claude Opus 4.6 — contained a logical error in the Oracle:
The price of cbETH/ETH was used.
But it was not hit in ETH/USD.
The result?
cbETH appeared at a price ≈ $1.12
Instead of ≈ $2,200

How to avoid "Malicious" Smart Contracts

Imagine ordering your fave coffee online, only for your bank account to suddenly empty instead of just paying for your latte. 😱 We often assume all crypto transactions are safe, but some 'smart contracts' hide nasty surprises.
Okay, so normally, a smart contract is like a super-smart vending machine for digital assets.

You put in your crypto, maybe some ETH, and it automatically gives you what you're expecting - like a new token or access to a service.

It's supposed to be reliable because the rules are written right into the code!

But here's the scary part: what if that vending machine isn't honest?

What if it's coded to take more than just the advertised fee, or even drain your wallet after you 'approve' a simple interaction?

Therefore, always remember that 'approving' a transaction isn't just saying 'yes' to a purchase; it's giving a smart contract permission to interact with your assets.

The big lesson?

Before you hit that 'Approve' button, especially for new or unknown projects, always check the contract’s permissions.

Look for audits, read reviews, and if it asks for unlimited spending on a token like say, BNB, for a small transaction, that's a HUGE red flag.

You're not just confirming a payment; you're handing over the keys to your digital vault!💡
