SGAxe, [35] an SGX vulnerability published in 2020, extends a speculative execution attack on cache, [36] leaking content of the enclave. This allows an attacker to access private CPU keys used for remote attestation. [37] In other words, a threat actor can bypass Intel's countermeasures to breach SGX enclaves' confidentiality.
Speculative Store Bypass (SSB) (CVE-2018-3639) is the name given to a hardware security vulnerability and its exploitation that takes advantage of speculative execution in a similar way to the Meltdown and Spectre security vulnerabilities. [1] It affects the ARM, AMD and Intel families of processors.

In July 2023 a critical vulnerability in the Zen 2 AMD microarchitecture called Zenbleed was made public. [59] AMD released a microcode update to fix it. [60] In August 2023 a vulnerability in AMD's Zen 1, Zen 2, Zen 3, and Zen 4 microarchitectures called Inception [61] [62] was revealed and assigned CVE-2023-20569. According to AMD it is not ...
Windows 10 version 1903 and 1909, and Server Core installations of Windows Server, versions 1903 and 1909 [5] SMBGhost (or SMBleedingGhost or CoronaBlue ) is a type of security vulnerability , with wormlike features, that affects Windows 10 computers and was first reported publicly on 10 March 2020.
A keylogger running on the system will capture any typed passwords. [8] [3] A user with administrator privileges can install a new Security Support Provider (SSP). The new SSP will not be able to access stored password hashes, but will be able to capture all passwords after the SSP is installed. [8] [9]
As of Windows 10 Creators Update (Windows 10 version 1703), the Windows kernel is compiled with CFG. [21] The Windows kernel uses Hyper-V to prevent malicious kernel code from overwriting the CFG bitmap. [22] CFG operates by creating a per-process bitmap, where a set bit indicates that the address is a valid destination. Before performing each ...
In computer security, a sandbox is a security mechanism for separating running programs, usually in an effort to mitigate system failures and/or software vulnerabilities from spreading. The sandbox metaphor derives from the concept of a child's sandbox—a play area where children can build, destroy, and experiment without causing any real ...
