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.
Tamperproofing is a methodology used to hinder, deter or detect unauthorised access to a device or circumvention of a security system. Since any device or system can be foiled by a person with sufficient knowledge, equipment, and time, the term "tamperproof" is a misnomer unless some limitations on the tampering party's resources is explicit or assumed.
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
About 150 of the 500 cameras are out of commission due to "several technical problems," NBC News reported, citing an internal Border Patrol memo. ... citing an internal Border Patrol memo.
The goal of deterrence methods is to convince potential attackers that a successful attack is unlikely due to strong defenses. The initial layer of security for a campus, building, office, or other physical space can use crime prevention through environmental design to deter threats.
Due to the fact that security measures may vary depending on the data center design, the use of unique features, compliance requirements or the company's business goals, there is no set of specific measures that cover all possible scenarios. [23] There exist in general two types of data center security: physical security and virtual security. [24]
In a 2009 blog post, security analyst Joanna Rutkowska coined the term "Evil Maid Attack" due to hotel rooms being a common place where devices are left unattended. [ 1 ] [ 2 ] The post detailed a method for compromising the firmware on an unattended computer via an external USB flash drive – and therefore bypassing TrueCrypt disk encryption.
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 ...
