In cryptography, a timing attack is a side-channel attack in which the attacker attempts to compromise a cryptosystem by analyzing the time taken to execute cryptographic algorithms. Every logical operation in a computer takes time to execute, and the time can differ based on the input; with precise measurements of the time for each operation ...
Cache timing attacks also known as Cache attacks are a type of side-channel attack that allows attackers to gain information about a system purely by tracking cache access made by the victim system in a shared environment.
Cache-timing attacks rely on the ability to infer hits and misses in shared caches on the web platform. [54] One of the first instances of a cache-timing attack involved the making of a cross-origin request to a page and then probing for the existence of the resources loaded by the request in the shared HTTP and the DNS cache.
In 2002 and 2003, Yukiyasu Tsunoo and colleagues from NEC showed how to attack MISTY and DES symmetric key ciphers, respectively. In 2005, Daniel Bernstein from the University of Illinois, Chicago reported an extraction of an OpenSSL AES key via a cache timing attack, and Colin Percival had a working attack on the OpenSSL RSA key using the Intel processor's cache.
The September 11 attacks of 2001, in addition to being a unique act of terrorism, constituted a media event on a scale not seen since the advent of civilian global satellite links. Instant worldwide reaction and debate were made possible by round-the-clock television news organizations and by the internet.
And though Europe has seen many similar attacks − including a truck attack in 2016 that killed 86 and injured 434 - the United States has also seen multiple incidents before Wednesday's attack.
One of the earliest known instances of a pixel-stealing attack was described by Paul Stone in a white paper presented at the Black Hat Briefings conference in 2013. [6] Stone's approach exploited a quirk in how browsers rendered images encoded in the SVG format.
