Райтап In the Shadows

Это райтап об одном из заданий, которое мы приготовили для отборочного этапа CTFZone, прошедшего в конце ноября. О процессе подготовки к квалификации можно прочитать здесь.

Вы начинаете с двумя файлами: decrypt_flag.py и ntfs_volume.raw. Давайте взглянем на скрипт. Он открывает файл c именем key.bin, а затем при помощи цикла пробует взять из каждого смещения внутри файла бинарную строку размером 34 байта, которая затем используется в качестве входных данных для функции PBKDF2. Каждый возвращенный ключ используется в качестве XOR-ключа для расшифровывания вшитой в код зашифрованной строки. Если в расшифрованной форме ее хеш MD5 совпадает с заранее определенным значением, скрипт использует полученные данные, чтобы сформировать и напечатать флаг.

Facebook плачет, Social Links смеется, Maltego курит

И снова здравствуйте, дорогие друзья. Очень рад, что вы следите за публикациями и пришли прочесть новую статью из цикла про Maltego. Изначально, я планировал объединять плагины и делать обзор на 2-3 сразу. Однако, окунувшись в первый же дополнительный продукт для Maltego, а именно Social Links, я вдруг осознал всю тщетность данного пути.

Если не читали предыдущие статьи, то обязательно ознакомьтесь с ними: Maltego часть 1 и часть 2. Там мы рассматривали, что же такое Maltego и как оно выглядит.

Goldilocks Zones and Stars #119 The Goldilocks zone is the habitable zone around a star where it’s not too hot and not too cold for liquid water to exist on the surface of orbiting planets. This intriguing infographic includes relative sizes of those zones for yellow G stars like the Sun, along with orange K dwarf stars and red M dwarf stars, both cooler and fainter than the Sun. M stars (top) have small, close-in Goldilocks zones. They are also seen to live long (100 billion years or so) and are very abundant, making up about 73 percent of the stars in the Milky Way. Still, they have very active magnetic fields and may produce too much radiation harmful to life, with an estimated X-ray irradiance 400 times the quiet Sun. Sun-like G stars (bottom) have large Goldilocks zones and are relatively calm, with low amounts of harmful radiation. But they only account for 6 percent of Milky Way stars and are much shorter lived. In the search for habitable planets, K dwarf stars could be just right, though. Not too rare they have 40 billion year lifetimes, much longer than the Sun. With a relatively wide habitable zone they produce only modest amounts of harmful radiation. These Goldilocks stars account for about 13 percent of the stars of the Milky Way. via NASA https://apod.nasa.gov/apod/ap200131.html

1. CheckFlow — быстрый и бесплатный комплексный аудит внутреннего сетевого трафика с помощью Flowmon



Добро пожаловать на наш очередной мини курс. На этот раз мы поговорим о нашей новой услуге — CheckFlow. Что это такое? По сути, это просто маркетинговое название бесплатного аудита сетевого трафика (как внутреннего, так и внешнего). Сам аудит производится с помощью такого замечательного инструмента как Flowmon, которым может воспользоваться абсолютно любая компания, бесплатно, в течении 30 дней. Но, я уверяю, что уже после первых часов тестирования, вы начнете получать ценную информацию о своей сети. Причем эта информация будет ценной как для сетевых администраторов, так и для «безопасников». Что ж, давайте обсудим, что это за информация и в чем ее ценность (В конце статьи как обычно видеоурок).

Two Custers and a Comet #119 This lovely starfield spans some four full moons (about 2 degrees) across the heroic northern constellation of Perseus. In telescopic exposures made during the nights of January 24, 26, and 28 it holds the famous pair of open or galactic star clusters h and Chi Persei with comet PanSTARRS (C/2017 T2) captured each night as it swept left to right across the field of view. Also cataloged as NGC 869 (right) and NGC 884, both star clusters are about 7,000 light-years away and contain stars much younger and hotter than the Sun. Separated by only a few hundred light-years, the clusters are both 13 million years young based on the ages of their individual stars, evidence that they were likely a product of the same star-forming region. Discovered in 2017 while still beyond the orbit of Saturn, Comet PanSTARRs is a new visitor to the inner solar system and just over 13 light-minutes from planet Earth. Always a rewarding sight in binoculars, the Double Cluster is even visible to the unaided eye from dark locations. C/2017 T2 could remain a telescopic comet though. One of the brightest comets anticipated in 2020 it makes its closest approach to the Sun in early May. via NASA https://apod.nasa.gov/apod/ap200130.html

Похек Wi-Fi встроенными средствами macOS

TL;DR Встроенные средства macOS позволяют выполнить некоторые атаки на Wi-Fi-сети. В статье описывается, как с помощью встроенного в Macbook Wi-Fi адаптера AirPort и macOS осуществить частичный взлом жопы.

Обычно для аудита безопасности Wi-Fi-сетей используется классическая связка: виртуалка с Kali Linux + внешний USB адаптер типа Alfa AWU-blabla1337. Но оказывается, что с помощью macOS и встроенного адаптера Broadcom тоже можно делать грязь.

Содержимое статьи:

  • Мониторный режим на встроенном адаптере
  • Расшифровываем WPA трафик
  • Ловим хендшейки и PMKID
  • Собираем под макось пацанские тулзы: hcxtools, bettercap
  • Брутим материал на чужих фермах на халяву
