🚨 Two weeks ago, Ledger's Genuine Check passed on implanted devices. Now @KeystoneWallet authenticity key is in an attacker's hands.
The WebAuth key is burned into each device at the factory and can't be rewritten. Whoever holds it can build counterfeits that verify as real.
🚨 1,404 Qubic wallets drained in 104 minutes
The seeds came from a generator with too little randomness on iPhone, iPad and Safari. The attacker didn't steal keys - he predicted them.
⚠️ v4.26.4 fixes the generator. It cannot fix a seed it already made.
🚨 Important Update from the @blur_io team
Blur contracts are upgradable, meaning their logic can be changed through upgrades
⚠ To avoid future security issues, revoke all contract approvals in one click using De.Fi Shield
Stay safe de.fi/shield🛡️
🚨 ~$93M DRAINED FROM 311 WALLETS BY A CHIP INSIDE THE DEVICE
Ledger confirmed a physical implant in wallets sold by reseller CryptoBilis: a microcontroller, LTE radio and eSIM hidden under the screen padding.
It read the recovery phrase off the display and texted it out.
🚨 ~$86M reportedly drained from Ledger users
What's confirmed: hundreds of victim wallets across ETH, TRON and BTC, traced by @SpecterAnalyst. 211+ BTC sitting unmoved in three addresses
What's not: the vector. No Ledger exploit is confirmed and the company hasn't commented

🚨 $768M LOST IN SEPTEMBER - THE WORST MONTH OF 2026
@bitget ~$388M. @Liquid_BTC $320M. Together, over 90% of the total.
Neither was a smart contract bug. One was a backend spoofing its own authorization. The other, a federation wallet.
The code wasn't the problem.
🚨 ~$351.6M GONE FROM BITGET - THE BIGGEST HACK OF 2026
Hot and warm wallets drained across multiple chains in under an hour. Bitget says cold wallets are secure. Withdrawals paused.
⚠️ Deposits and trading are still live. Don't add to a balance you can't withdraw.
🚨 MALICIOUS CODE FOUND IN FOMOPEEK v1.1–1.2 ON iOS
@wallet and @SlowMist_Team found the app may expose private keys, seed phrases and credentials.
⚠️ Installed it? Create a NEW wallet on a device FomoPeek never touched. Move your funds there.
New keys. Not your old seed.
/ 🚨 ~$600K DRAINED - AND THE VICTIM TYPED THE COMMAND HIMSELF
An Axiom trader was bridging to @arc when a site showed him a Cloudflare "verify you are human" page.
/ What happened next says everything: the drain was manual. The attacker moved the SOL, came back 5 minutes later for ~$500 in USDC and USDT, then sent 0.5 SOL back 30 minutes on to keep selling tokens.
Someone was sitting at that keyboard for half an hour.
🚨 The phishing email referenced a real vulnerability
Trezor and BitBox users got emails warning of a "critical STM32 entropy vulnerability" - weeks after a real STM32 entropy flaw drained tens of millions from Coldcard wallets.
⚠️ And they came from the real domains.
🚨 ~4,000 bitcoin:native (~$320M) DRAINED FROM @Liquid_BTC FEDERATION WALLET
~95% of the reserve backing L-BTC.
Network operations halted. Exchanges froze L-BTC deposits and withdrawals.
⚠️ Do not trade L-BTC until the funds are back.
🚨 ~$75M DRAINED FROM TECTONIC ON CRONOS
No contract bug. The attacker pumped the illiquid tectonic:native ~100x in 24 minutes and borrowed against the inflated price.
Cronos validators halted the chain. ~$6M was already out.
Illiquid collateral is an oracle you don't control.
🚨@MANTRA_Chain CHAIN IS OFFLINE
An attacker exploited a vulnerability in an upstream dependency. The team halted the chain as a precaution - endpoints, transactions and bridge operations are all frozen.
$OM fell 18.6% to an all-time low.
⚠️ Deposits and withdrawals on connected exchanges are affected.
Don't send anything to MANTRA addresses until the patched release is live.
