Critical Security Vulnerabilities Discovered in Hardware Wallets and Blockchain Code
Security researchers discovered that certain Ledger hardware wallets sold through CryptoBilis contained hidden LTE-enabled chips that could transmit private wallet keys. Ledger confirmed these were unauthorized 'spy implants' inserted into counterfeit wallets sold through unofficial channels. MediaMarktSaturn immediately pulled Ledger products from shelves following the discovery. A serious bug was found in XRP blockchain code that existed for years and could have broken the 100 billion XRP supply limit if exploited. Cryptocurrency exchange hacks reached $1.2 billion in losses during Q3 2026, including major exploits at Bitget and Liquid. A Bitget exchange hack was exploited with stolen funds moved through Zcash to hide traces. These incidents highlight that security remains critical throughout the crypto ecosystem, from hardware wallets to exchange platforms to underlying blockchain code.
Warum es wichtig ist
Even trusted hardware wallet brands can be compromised through the supply chain, so you should only buy from official retailers. Major exchange hacks show why experienced users prefer storing crypto offline in personal hardware wallets rather than leaving large amounts on trading platforms.
