Hidden Chip Found Inside a Ledger Wallet - Is Cold Storage Still Safe?
A reported case involving a modified Ledger device has raised concerns about hardware wallet security. An additional chip was allegedly hidden beneath the screen, with the compromised device linked to losses exceeding $86M The concerning detail is that some modified devices may still pass standard authenticity checks if their original secure element remains intact
The Real Vulnerability
Hardware wallets are designed to keep private keys isolated from internet-connected devices. However, that protection becomes less reliable when the physical device itself has been compromised A malicious component could potentially manipulate displayed information or interfere with the wallet initialization process This highlights an important distinction: cryptographic authenticity does not necessarily guarantee that every physical component is trustworthy
Research View
The incident reinforces the importance of supply-chain security Buying directly from official sources, generating recovery phrases independently, rejecting preconfigured wallets and verifying transaction details are essential precautions For suspected compromised devices, simply resetting the wallet may not eliminate the underlying risk Cold storage protects private keys. But that protection still depends on trusting the hardware holding them
Al (Claude) found a critical 4-year bug in Zcash's Orchard shielded pool (since 2022). Could've let attackers mint unlimited fake ZEC undetected.
No exploitation found, team patched it quick with emergency fork. But ZEC still crashed 30-50%, wiping $5B+ market cap. Privacy coins stay risky af. Trust hit hard.
The bug has been fixed, but it's still unclear whether any fake ZEC was created before the fix.
Future for $ZEC ? Could bounce if they nail better audits + upgrades, or keep bleeding if more FUD hits.
Long term privacy play might recover, but volatile as hell rn. #ZECUSDT #zec $
A hacker who exploited GMX's smart contracts to steal $42 million in cryptocurrencies has returned $40.5 million after accepting a $5 million bounty offered by GMX. The attack, a re-entrancy exploit, targeted GMX V1's design flaw, inflating GLP token prices and stealing assets like $ETH and $FRAX. GMX confirmed its V2 protocol was unaffected and lifted minting caps on liquidity tokens. GMX's token has recovered, rising over 13% following the incident resolution. #Write2Earn

Someone just sold 10,000 $BTC after 14 yrs today, bought it for $0.78 per bitcoin back in 2011. The amount of patience it takes remains unmatched. #Write2Earn
Ouch! The German government sold 49,858 $BTC at $57,900 ($2.89B) in July 2024. With $BTC at $109,452 in July 2025 one year later, they would've netted $5.45B! That's a $2.57B miss! Don't sell your Bitcoin! #Binance #BinanceSquareTalks $BTC
