Security & Exploits ·
Ledger confirmed a hardware tampering attack this week involving a Southeast Asian reseller, representing a security breach in the supply chain for the hardware wallet provider. In separate developments, Solana announced its Alpenglow mainnet upgrade, which targets 150ms finality as a key performance improvement. Meanwhile, US inflation data showed the September unadjusted consumer price index rose to 3.7% year-over-year, marking the highest level since May and surpassing market expectations of 3.6%; the month-over-month figure reached 0.6%, the highest since April.
The week also brought regulatory and legal activity across multiple jurisdictions. A UK court ruling involved 61,000 BTC, and Australia introduced new crypto regulations. Additionally, BitMine's ETH holdings approached 5% of total supply, signaling a notable concentration of ether by the entity.
Key unknowns remain around the scope and impact of the Ledger tampering incident—the number of affected devices and the reseller's operational reach have not been detailed. The Alpenglow upgrade's rollout timeline and technical feasibility at the stated finality target are also pending clarification. Broader market pressure is evident, with the Nasdaq 100 closing down 5.5% for the week, its largest weekly decline since April 2025.
