1/ Tampered #Ledgers with a hidden cellular implant are being sold through third-party resellers in Southeast Asia.
The implant reads your 24 words during setup and sends them over LTE. Genuine Check doesn't catch it.

Good read from @xccy_finance and Schema Research on what fixed rates on lending do for treasuries, vaults and borrowers
What caught our eye: pricing the hedge into a vault’s share price. That is where vault security gets tested!
Borrow $500K on Aave for six months, and the interest bill could be $7,500 or $25,000, depending on where rates go
Fix the rate at 6% and the bill is $15,250, fees included
We worked through cases like this in a new piece 👇

Proud to keep building with @X1_EcoChain after auditing their Layer 1.
We know the base layer inside out: the Go node and the system contracts. That gives every team launching on X1 EcoChain a head start on security
X1 EcoChain 🤝 Hashlock: Elevating Ecosystem Security and Unlocking Exclusive Perks for Builders!
We are thrilled to highlight our successful partnership with @Hashlock_ — a premier Australian smart contract and decentralized systems auditor with an impeccable global reputation for blockchain security.
Having already completed the comprehensive audit of our Layer 1 blockchain, Hashlock's security experts possess an intimate, hands-on understanding of our underlying architecture and codebase. This gives projects building within the X1 EcoChain ecosystem a massive advantage.
Thanks to this established technical baseline, upcoming ecosystem projects can undergo security audits with Hashlock much faster, more smoothly, and on exclusive, highly favorable terms.
Empowering the next generation of secure, scalable Web3 projects — together with the industry's best!

4. Most of the money left in about 20 minutes, across 10 blockchains (TRM Labs).
About $3B is already frozen, and Binance says it will cover all losses. TRM links the attack to North Korea's TraderTraitor group.

1. An attacker got into the laptop of a Binance engineer.
2. From it, they reached the internal system that sends withdrawals.
3. That system signed the attacker's withdrawals as if they were real.
Binance says it found no sign of a private key leak.

zkLink Nova's bridge on Ethereum lost about $786K, flagged by Blockaid on 29 Oct.
The root cause was simple: one message hash that could be used twice.
zkLink has not published a post-mortem yet. Here is what the analyses show.

For any bridge or messaging layer:
- Mark a message hash as used in the same call that consumes it
- Require a fresh authenticated callback for every claim
- Treat functions a public relayer can reach as untrusted input

With that root accepted, withdrawals with forged proofs went through, draining the ETH escrow and the ERC20 bridge.
One attacker address SlowMist lists is tagged "X100 Exploiter 2" on Etherscan, the same label as the X100 governance attack on 24 Oct.
