A newly identified vulnerability in Apple’s M-series processors could have dire implications for crypto users, with the potential to compromise the private keys essential for securing digital assets. This flaw, which resides deep within the microarchitecture of these chips, was first reported by Ars Technica and detailed in a paper published by a collective of researchers from top US universities.
Mac Users Beware: This Is Crucial For Crypto Owners
The vulnerability stems from a side channel in the chip’s data memory-dependent prefetcher (DMP), a mechanism designed to enhance computing efficiency. However, this feature inadvertently allows for the extraction of secret keys during cryptographic operations, a process that is fundamental to the security of cryptocurrencies and other digital transactions.
“The DMP […] uses the data values in order to make predictions […] if a data value ‘looks like’ a pointer, it will be treated as an ‘address’ […] the data
