A Secure Wallet, a Compromised Reseller: What the CryptoBilis Incident Revealed
A hardware wallet supply chain security incident: Ledger confirmed that devices sold through reseller CryptoBilis contained an implanted component capable of stealing 24-word recovery phrases. Trezor then warned that a Safe 5 device bought from the same reseller appeared to have an extra circuit board added, though that device has not yet been inspected. Trezor advised users who bought its products through CryptoBilis since March 2026 to move funds to a new wallet and replace their recovery phrases. A Bitquery investigation says the related thefts involved 335 wallets across six blockchains and about $102 million. Neither vendor has publicly confirmed that the same attacker was responsible.

Sible Network Shelves Three-Account Mining Plan Over Sybil Attack Concerns
Sible Network proposed on November 1 a plan to let a single phone run three mining accounts, aiming to help households that can't afford multiple devices. But community members and ambassadors worried the arrangement would encourage fake accounts, reward farming, and unfair mining, and could trigger Sybil attacks. On November 2, the project announced it was pausing the pilot, reaffirming its 'one person, one account' policy that bars individuals from operating multiple accounts. Sible said the original proposal was meant to help families who can't afford separate phones, but decided to suspend it after reconsideration.

CZ Hits Back at Musk's Binance Hack Mockery, Points to $1B SpaceX Stake
Binance founder Changpeng Zhao (CZ) publicly called on Elon Musk to stop mocking Binance over a hack, after Musk responded to CZ's security warning with laughing emojis and the comment "Everyday is Zeroday."

Co-CEO He Yi said the company's annual revenue is enough to cover the losses without selling shares. Binance estimates the October 29 security incident affected about $6.3 billion in assets, of which roughly $3 billion has been frozen.

Former Ripple CTO Mocks $6 Billion Binance Hack with a Stellar (XLM) Joke
The article reports on the largest hack in Binance's history, with losses of roughly $6.3 billion across 10 blockchain networks. Former Ripple CTO David Schwartz mocked the hackers with a Stellar (XLM) joke after they accidentally sent 517 extra XLM to a victim's account. The attackers stole 233.46 million XRP (about $296 million) from Binance hot wallets; because the XRP Ledger's architecture prevents forced freezes, recovery is difficult. However, the Ripple team urgently froze about $200 million in RLUSD stablecoins, and Binance co-founder Yi He publicly thanked them. Blockchain sleuths identified the North Korean hacking group TraderTraitor (Lazarus) as the culprit, and roughly $3 billion in assets has now been frozen.

Trezor Warns of Suspected Hardware Implant in CryptoBilis Wallets
Trezor is warning customers who bought hardware wallets through former authorized reseller CryptoBilis to move their funds immediately. An Indonesian customer reported that a Trezor Safe 5 purchased in August 2026 appeared to contain an added circuit board and cellular module capable of reading and remotely transmitting the recovery phrase shown on the wallet's screen. Trezor reviewed photos and interviewed the customer by video; although no physical inspection was performed, it considers the report credible and advises users who bought affected devices since March 2026 to create a new wallet and replace their recovery phrase. No losses have been reported so far. CryptoBilis had its authorization revoked on October 9, and Ledger previously confirmed that devices sold by the same reseller had been physically tampered with.

Binance Hack Could Give Uniswap a Boost as Standard Chartered Eyes DEX Growth
Standard Chartered's head of digital asset research, Geoffrey Kendrick, believes the roughly $6.3 billion Binance hack could push traders toward decentralized exchanges, with Uniswap poised to be a major beneficiary. He maintains his $100 price target for UNI by 2030 and urges investors to revisit Uniswap. Data shows the DEX-to-CEX spot trading volume ratio rose to 23.5% in Q2 2026. UNI fell over 10% after the incident, while Hyperliquid's HYPE gained about 15% on news of an ICE partnership. Kendrick warns token prices could fall further before the market stabilizes.
