BreachForums staff claims to have seized a server containing files tied to both old ShinyHunters (YuroSH) and current operator James, including ransomware logs, exclusive videos and private chats with high-profile cybercriminals. They also claim the main suspect has been arrested by French police.
Dump expected by April 23 at 10PM GMT.
Is this a coordinated takedown?

On April 23, 2011, Satoshi Nakamoto sent his final known message, telling Gavin Andresen that Bitcoin was “in good hands” and that he had “moved on to other things.” No one has heard from him since.
Where do you think he is?

Would you pay $25K for a Telegram gift?

An attacker exploited a critical signature flaw in GiddyDefi's GiddyVaultV3, replaying a valid signature with swapped parameters to drain $1.3M in staked LP tokens.
TX: 0x5edb…82e5
EXPLANATION:
The vault's signature verification only checked the data bytes inside each SwapInfo struct, ignoring critical fields like the aggregator address, token addresses and amount. The attacker took a legitimate signed transaction, replaced the aggregator with their own malicious contract, swapped the tokens for the vault's staked LP tokens, and set the amount to MAX_UINT256 to drain everything. The signature was valid, the vault approved it, funds gone.
Another audit that missed the obvious.

26 malicious apps impersonating MetaMask and Coinbase slipped through Apple's review, all linked to China-region developer accounts, capturing seed phrases via phishing, OCR scanning and injected code. A fake Sparrow Wallet app also made it through, draining wallets the moment a seed phrase is entered.
Apple defended its App Store just days ago. How's that going?

Italian researcher Giancarlo Lelli won Project Eleven's Q-Day Prize by breaking a 15-bit elliptic curve key on publicly accessible quantum hardware, a 512x jump from the previous record set in September 2025. Not an immediate threat to Bitcoin's 256-bit security, but estimates for the qubits needed to crack it have dropped to under 500,000. Around 6.9M BTC sits in wallets with exposed public keys.
EXPLANATION:
Bitcoin uses 256-bit elliptic curve cryptography to secure wallets. A quantum computer running Shor's algorithm could theoretically derive a private key from a public key, stealing funds. Until now, quantum attacks on ECC were purely theoretical or limited to trivial 6-bit demos. Lelli's 15-bit result, done on cloud quantum hardware with no private chips or national lab, proves the attack class works in practice. The gap from 15-bit to 256-bit is still enormous, but the required resources keep shrinking fast.
Is Bitcoin moving fast enough on post-quantum upgrades?

France has recorded 41 physical attacks and kidnappings targeting crypto holders in the first 3.5 months of 2026 alone, according to Telegram CEO @durov. Authorities have linked part of the surge to tax database leaks exposing crypto owners' personal data to criminals.

Litecoin suffered a 51% attack allowing attackers to double-spend the same coins. They swapped LTC for other assets, then rewrote blockchain history to reclaim the original LTC, keeping both. Total losses have reached 8 figures. Litecoin Cash, a fork of Litecoin, suffered a similar attack in the past, but this marks the first time it has hit Litecoin's mainnet directly.
EXPLANATION:
A 51% attack happens when a single entity controls more than half of a blockchain's mining power. With majority control, they can secretly mine an alternate version of the blockchain and replace the legitimate chain, effectively erasing transactions that already happened. In this case, attackers made swaps to receive assets, then used their hashrate dominance to reorg the chain and erase the outgoing LTC transactions, ending up with both the LTC and whatever they received in the swap.
Is Litecoin's proof-of-work security still worth trusting?

Litecoin has confirmed the incident was caused by a zero-day bug in MWEB, not a coordinated 51% attack. Non-updated nodes accepted an invalid transaction, triggering a DoS on major mining pools and a 13-block reorg. The invalid transactions were reversed and will not be included in the main chain. All valid transactions remain unaffected. Bug is fully patched, network back to normal.

The Satoshi Nakamoto statue in Parco Ciani, Lugano, was vandalized again on April 19, with its steel structure bent and destroyed. It was previously thrown into Lake Lugano in August 2025, repaired and reinstalled in October 2025. The statue is currently being restored, and plans are underway to move it to a new location. The Lugano Satoshi Museum responded: "You can bend steel, but you cannot distort its meaning."

In 1995, Anguilla was randomly assigned the .ai domain (like .us, .uk, etc.). Nobody cared. Fast forward to the AI boom, and it’s now generating tens of millions per year for an island of 18,000 people.
Best accidental investment in history?

Scammers (most likely girls) may approach you and invite you to play Minecraft. As part of the setup, they’ll ask you to install a mod-pack but this pack can contain malware that gives them full access to your PC.
One known method involves importing a code into CurseForge, which silently includes a malicious .jar file designed to infect your system.
Stay alert and don't give in to pressure - be cautious when someone you just met online asks you to do anything.

Hundreds of crypto wallets inactive for 7+ years were suddenly drained by a single phishing address flagged on Etherscan, stealing over $X'XXX'XXX across hundreds of victims.
Separately, a compromised private key allowed an attacker to silently upgrade Syndicate Labs' bridge contracts, moving 18.5M $SYND (~$330K) and ~$50K in customer tokens. All affected Syndicate users will be fully refunded.
