Thunderspy is a type of security vulnerability, based on the Intel Thunderbolt 3 port, first reported publicly on 10 May 2020, that can result in an evil maid (i.e., attacker of an unattended device) attack gaining full access to a computer's information in about five minutes, and may affect millions of Apple, Linux and Windows computers, as well as any computers manufactured before 2019, and ...
[59] [60] "Kernel Direct Memory access (DMA) Protection" only protects against attacks through Thunderbolt. Direct Memory Access is also possible through PCI Express . In this type of attack an attacker would connect a malicious PCI Express Device, [ 61 ] which can in turn write directly to the memory and bypass the Windows login.
An attacker could, for example, use a social engineering attack and send a "lucky winner" a rogue Thunderbolt device. Upon connecting to a computer, the device, through its direct and unimpeded access to the physical address space, would be able to bypass almost all security measures of the OS and have the ability to read encryption keys, install malware, or control other system devices.
Additionally, SMAP can expose flawed kernel code which does not follow the intended procedures for accessing user-space memory. [ 1 ] However, the use of SMAP in an operating system may lead to a larger kernel size and slower user-space memory accesses from supervisor code, because SMAP must be temporarily disabled any time supervisor code ...
AppArmor ("Application Armor") is a Linux kernel security module that allows the system administrator to restrict programs' capabilities with per-program profiles. Profiles can allow capabilities like network access, raw socket access, and the permission to read, write, or execute files on matching paths.

An off-duty New York City cop has been arrested for allegedly raping and strangling someone close to him, sources told The Post Saturday. Samuel Sierra, 35, was arrested around 7:20 p.m. Friday ...
Address space layout randomization (ASLR) is a computer security technique involved in preventing exploitation of memory corruption vulnerabilities. [1] In order to prevent an attacker from reliably redirecting code execution to, for example, a particular exploited function in memory, ASLR randomly arranges the address space positions of key data areas of a process, including the base of the ...
