The Password Game — это популярная в интернете абсурдная браузерная головоломка, созданная Нилом Агарвалем, где игроку нужно создать пароль, соответствующий всё более безумным и нестандартным правилам, включающим математические задачи, шахматные правила, игры типа GeoGuessr и логические головоломки.

Игра начинается с простых требований (длина, цифры, буквы), но быстро усложняется, требуя от игрока использовать логику, ассоциации, эрудицию и смекалку для выполнения всех предыдущих условий, чтобы перейти к следующему этапу.

А сколько уровней игры сможешь пройти ты?

👍 Kaspersky Reverse Challenge Cup 2017

Kaspersky Reverse Challenge Cup on Zero Nights (Moscow, Russia) likely refers to a reverse engineering malware competition or challenge organized by Kaspersky Lab, possibly with a focus on scenarios where participants have limited time to analyze and solve problems.

Парни, кто решал crackme от ЛК в 2010-х годах? Это было эпично, мой первый дебют после самооучения реверсу (CrackLab, ExeLab many thanks) состоявшийся на ZN 2017. Бинарик уже потерян, но солюшн остался в черновиках. Если интересно ставьте👍 попробуем превратить его в райтап 👍

National Cryptologic Museum Tour, US, Maryland state

The National Cryptologic Museum (NCM) is an American museum of cryptologic history that is affiliated with the National Security Agency (NSA). The first public museum in the U.S. Intelligence Community, NCM is located in the former Colony Seven Motel, just two blocks from the NSA headquarters at Fort George G. Meade in Maryland. The motel was purchased, creating a buffer zone between the high security main buildings of the NSA and an adjacent highway. The museum opened to the public on December 16, 1993, and now hosts about 50,000 visitors annually from all over the world.

The NCM collection contains thousands of artifacts, including numerous working World War II German Enigma machines (two of them are available for visitors to try out), and a Navy Bombe used to break it. Displays discuss the history of American cryptology and the people, machines, techniques, and locations concerned. Initially housing NSA artifacts for viewing by employees, the museum quickly developed into a collection of U.S. cryptologic history, with some artifacts dating back to pre-American Revolutionary War times.

In addition to exhibits covering equipment used to encrypt, decrypt, and secure information, the museum features exhibits on the people who contributed to cryptography in America, such as George Washington (who integrated military intelligence tactics, including coded messaging, into the Continental Army during the Revolutionary War), the Native American code talkers (who protected U.S. communications during both World Wars by using their native languages to encode message traffic), and the Navy WAVES (who, like the WRENS of the British Royal Navy, operated the Bombe to decrypt German military traffic during WWII).
