TEE.Fail attack breaks confidential computing on Intel, AMD, NVIDIA CPUs

Academic researchers developed a side-channel attack called TEE.Fail, which allows extracting secrets from the trusted execution environment in the CPU, the highly secure area of a system, such as Intel’s SGX and TDX, and AMD’s SEV-SNP. The method is a memory-bus interposition attack on DDR5 systems that could be successfully done by computer hobbyists a cost of less than […]

New Phoenix attack bypasses Rowhammer defenses in DDR5 memory

Academic researchers have devised a new variant of Rowhammer attacks that bypass the latest protection mechanisms on DDR5 memory chips from SK Hynix. A Rowhammer attack works by repeatedly accessing specific rows of memory cells at high-speed read/write operations to cause enough electrical interference to alter the value of the nearby bits from one to […]

Can DDR5 Motherboards Use DDR4 RAM?

When it comes to upgrading or building a computer, one common question arises: can DDR5 motherboards use DDR4 memory? The short answer is no. DDR5 and DDR4 memories are not interchangeable, primarily due to differences in physical design, pin configuration, and voltage requirements. DDR5 is the latest standard in memory technology, offering faster speeds and higher capacity […]
