El Reg talks to Dr Yuval Yarom about Intel's memory leaking catastrophe

Interview In the wake of yet another collection of Intel bugs, The Register had the chance to speak to Foreshadow co-discoverer and University of Adelaide and Data61 researcher Dr Yuval Yarom about its impact.
Dr Yarom explained that one of the big impacts of Foreshadow is that it destroys an important trust model – SGX attestations, which guarantee that the code you publish is the code someone else is running.
Think of it as tamper-evident packaging for software: having published ...

Three more data-leaking security holes found in Intel chips as designers swap security for speed

Apps, kernels, virtual machines, SGX, SMM at risk from attack

Intel will today disclose three more vulnerabilities in its processors that can be exploited by malware and malicious virtual machines to potentially steal secret information from computer memory.
These secrets can include passwords, personal and financial records, and encryption keys. They can be potentially lifted from other applications and other customers' virtual machines, as well as SGX enclaves, and System Management Mode (SMM) memory. SGX is Intel's technology that is supposed to p...

Researchers Disclose New Foreshadow (L1TF) Vulnerabilities Affecting Intel CPUs
BleepingComputer • Catalin Cimpanu • 14 Aug 2018

Academics and private sector researchers have revealed details today about three new vulnerabilities affecting Intel CPUs.
All three are Spectre-class attacks that take advantage of a CPU design feature named speculative execution —a feature found in all modern CPUs that has the role of improving performance by computing operations in advance and later discarding unneeded data.
These flaws target data processed during speculative execution that is stored inside a processor's L1 cac...
