Vulnerability Disclosures

  • 00:01:27 GoFetch: “Unpatchable vulnerability in Apple chip leaks secret encryption keys” [Arstechnica]
    • A vulnerability has been discovered in Apple’s M-series chips, allowing attackers to extract secret keys from Macs during cryptographic operations.
    • The flaw stems from the microarchitectural design of the chips and cannot be patched directly.
    • The vulnerability exploits the chips’ data memory-dependent prefetcher, which predicts memory addresses and can leak information through a side channel.
    • Mitigating the vulnerability requires additional defenses such as ciphertext blinding, potentially doubling computing resources needed.
    • Apple’s latest chip, the M3, has a feature to disable the vulnerable prefetcher, but the performance penalty of doing so is yet to be determined.
  • 00:04:38 Vulnerability discovered in ViaBTC’s SPV mining code [Bitcoin Developer 0xB10C blog post]
    • Improper input validation in SPV mining module allows remote attack to waste hashrate.
    • Failure to verify merkle root in received blocks permits mining on old blocks.
    • ViaBTC confirms receipt, fixes vulnerability, and awards bounty.
    • Issue still exists in open-source viabtc_mining_server despite fixes in ViaBTC’s systems. [GitHub ViaBTC mining server issue #16]
  • 00:06:07 SIM swappers hijacking phone numbers in eSIM attacks [Bleeping Computer]
    • SIM swappers are targeting eSIMs to hijack phone numbers and bypass security measures to access bank accounts and other secure services.
    • eSIM technology allows for digital storage and reprogramming of subscriber identity modules on devices, promoting ease of transfer and increased adoption in modern smartphones and wearables.
