The asymmetric backdoor utilizes a twisted pair of elliptic curves resulting in a discrete log kleptogram that easily fits into the hello nonce. The attack is an attack on SSL random number generation. The act of generating a hello nonce using the EC-DRBG that NIST backdoored mimics exactly this attack on SSL by Young and Yung. August 2007
Cryptographic attacks that subvert or exploit weaknesses in this process are known as random number generator attacks. A high quality random number generation (RNG) process is almost always required for security, and lack of quality generally provides attack vulnerabilities and so leads to lack of security, even to complete compromise, in ...
NoScript can force the browser to always use HTTPS when establishing connections to some sensitive sites, in order to prevent man-in-the-middle attacks. This behavior can be triggered either by the websites themselves, by sending the Strict Transport Security header, or configured by users for those websites that don't support Strict Transport Security yet.
The Nessus Attack Scripting Language, usually referred to as NASL, is a scripting language that is used by vulnerability scanners like Nessus and OpenVAS. With NASL specific attacks can be automated, based on known vulnerabilities. Tens of thousands of plugins have been written in NASL for Nessus and OpenVAS. [1]
For instance, AFL is a dumb mutation-based fuzzer that modifies a seed file by flipping random bits, by substituting random bytes with "interesting" values, and by moving or deleting blocks of data. However, a dumb fuzzer might generate a lower proportion of valid inputs and stress the parser code rather than the main components of a program.
BlackEnergy Malware was first reported in 2007 as an HTTP-based toolkit that generated bots to execute distributed denial of service attacks. [1] It was created by Russian hacker Dmyrtro Oleksiuk around 2007. Oleksiuk also utilized the alias Cr4sh. [2] In 2010, BlackEnergy 2 emerged with capabilities beyond DDoS.
A key encapsulation mechanism, to securely transport a secret key from a sender to a receiver, consists of three algorithms: Gen, Encap, and Decap. Circles shaded blue—the receiver's public key and the encapsulation —can be safely revealed to an adversary, while boxes shaded red—the receiver's private key and the encapsulated secret key —must be kept secret.
Where those random numbers fail to be actually random, any subsequent statistical analysis may suffer from systematic bias. Elements of statistical practice that depend on randomness include: choosing a representative sample of the population being examined, disguising the protocol of a study from a participant (see randomized controlled trial ...
