The Smurf Amplifier Registry is a blacklist of networks on the Internet which have been misconfigured in such a way that they can be used, as smurf amplifiers for smurf denial of service attacks. It can probe networks for vulnerability to smurf amplification, and then will either add them to its database, or remove them from the database ...
A Valeriepieris circle [1] [2] [3] is a figure drawn on the Earth's surface such that the majority of the human population lives within its interior. The concept was originally popularized by a map posted on Reddit in 2013, made by a Texas ESL teacher named Ken Myers, whose username on the site gave the figure its name. [ 4 ]
Picking any two ciphers, if the key used is the same for both, the second cipher could possibly undo the first cipher, partly or entirely. This is true of ciphers where the decryption process is exactly the same as the encryption process (a reciprocal cipher) —the second cipher would completely undo the first.
On December 8, Zhaojun contacted the developers again detailing how the vulnerability was being discussed in public security chat rooms, was already known by some security researchers, and pleaded that the team expedite the solution to the vulnerability in the official release version of Log4j.

The safecracker will drill a hole allowing him to get his scope into a position to observe the change key hole. While spinning the dial and looking through the change key hole for certain landmarks on the combination lock's wheel pack, it is possible to obtain the combination and then dial open the safe with the correct combination.
Exploits are digital products, which means that they are information goods with near-zero marginal production costs. [7] However, they are atypical information goods. Unlike e-books or digital videos, they do not lose their value because they are easy to replicate but due to the fact that once they are exposed, the original developer will "patch" the vulnerability, decreasing the value of the ...
Humans generally do poorly at generating random quantities. Magicians, professional gamblers and con artists depend on the predictability of human behavior. In World War II German code clerks were instructed to select three letters at random to be the initial rotor setting for each Enigma machine message. Instead some chose predictable values ...
Later in life, vulnerability to accidents and age-related chronic disease such as cancer or cardiovascular disease play an increasing role in mortality. Extension of life expectancy and lifespan can often be achieved by access to improved medical care, vaccinations , good diet , exercise , and avoidance of hazards such as smoking .
