Obvious lies serve a purpose for an administration. They watch who challenges them and who loyally repeats them. The people must watch, too.

4 people are living in an isolated habitat for 30 days. Why? Science!

2016 Feb 1, 3:27

nasa:

This 30 day mission will help our researchers learn how isolation and close quarters affect individual and group behavior. This study at our Johnson Space Center prepares us for long duration space missions, like a trip to an asteroid or even to Mars.

image

The Human Research Exploration Analog (HERA) that the crew members will be living in is one compact, science-making house. But unlike in a normal house, these inhabitants won’t go outside for 30 days. Their communication with the rest of planet Earth will also be very limited, and they won’t have any access to internet. So no checking social media kids!

The only people they will talk with regularly are mission control and each other.

image

The crew member selection process is based on a number of criteria, including the same criteria for astronaut selection.

What will they be doing?

Because this mission simulates a 715-day journey to a Near-Earth asteroid, the four crew members will complete activities similar to what would happen during an outbound transit, on location at the asteroid, and the return transit phases of a mission (just in a bit of an accelerated timeframe). This simulation means that even when communicating with mission control, there will be a delay on all communications ranging from 1 to 10 minutes each way. The crew will also perform virtual spacewalk missions once they reach their destination, where they will inspect the asteroid and collect samples from it. 

A few other details:

  • The crew follows a timeline that is similar to one used for the ISS crew.
  • They work 16 hours a day, Monday through Friday. This includes time for daily planning, conferences, meals and exercises.  
  • They will be growing and taking care of plants and brine shrimp, which they will analyze and document.

But beware! While we do all we can to avoid crises during missions, crews need to be able to respond in the event of an emergency. The HERA crew will conduct a couple of emergency scenario simulations, including one that will require them to maneuver through a debris field during the Earth-bound phase of the mission. 

image

Throughout the mission, researchers will gather information about cohabitation, teamwork, team cohesion, mood, performance and overall well-being. The crew members will be tracked by numerous devices that each capture different types of data.

image

Past HERA crew members wore a sensor that recorded heart rate, distance, motion and sound intensity. When crew members were working together, the sensor would also record their proximity as well, helping investigators learn about team cohesion.

Researchers also learned about how crew members react to stress by recording and analyzing verbal interactions and by analyzing “markers” in blood and saliva samples.

image

In total, this mission will include 19 individual investigations across key human research elements. From psychological to physiological experiments, the crew members will help prepare us for future missions.

The Strange & Curious Tale of the Last True Hermit

2014 Aug 21, 3:02

The story of Chris Knight, living in isolation in the woods of Maine for 27 years.

'Anyone who reveals what he's learned, Chris told me, is not by his definition a true hermit. Chris had come around on the idea of himself as a hermit, and eventually embraced it. When I mentioned Thoreau, who spent two years at Walden, Chris dismissed him with a single word: “dilettante.”'

'But still, I pressed on, there must have been some grand insight revealed to him in the wild…”Get enough sleep.”'

I don’t want to brag, but I’ve been telling that people all along and I didn’t have to live alone in the woods for decades.

Does it betray my innocence that I’m shocked by the amount of exec($_GET you can easily find on github? Hilarious comment thread on hacker news: 

This is awful. Shell commands are not guaranteed to be idempotent, people! These should all be of the form exec($_POST, not exec($_GET.

Stripe CTF - XSS, CSRF (Levels 4 & 6)

2012 Sep 10, 4:43

Level 4 and level 6 of the Stripe CTF had solutions around XSS.

Level 4

Code

> Registered Users 

    <%@registered_users.each do |user| %>
    <%last_active = user[:last_active].strftime('%H:%M:%S UTC') %>
    <%if @trusts_me.include?(user[:username]) %>

  • <%= user[:username] %>
    (password: <%= user[:password] %>, last active <%= last_active %>)
  • Issue

    The level 4 web application lets you transfer karma to another user and in doing so you are also forced to expose your password to that user. The main user page displays a list of users who have transfered karma to you along with their password. The password is not HTML encoded so we can inject HTML into that user's browser. For instance, we could create an account with the following HTML as the password which will result in XSS with that HTML:

    
    
    This HTML runs script that uses jQuery to post to the transfer URI resulting in a transfer of karma from the attacked user to the attacker user, and also the attacked user's password.

    Notes

    Code review red flags in this case included lack of encoding when using user controlled content to create HTML content, storing passwords in plain text in the database, and displaying passwords generally. By design the web app shows users passwords which is a very bad idea.

    Level 6

    Code

    
    

    ...

    def self.safe_insert(table, key_values)
    key_values.each do |key, value|
    # Just in case people try to exfiltrate
    # level07-password-holder's password
    if value.kind_of?(String) &&
    (value.include?('"') || value.include?("'"))
    raise "Value has unsafe characters"
    end
    end

    conn[table].insert(key_values)
    end

    Issue

    This web app does a much better job than the level 4 app with HTML injection. They use encoding whenever creating HTML using user controlled data, however they don't use encoding when injecting JSON data into script (see post_data initialization above). This JSON data is the last five most recent messages sent on the app so we get to inject script directly. However, the system also ensures that no strings we write contains single or double quotes so we can't get out of the string in the JSON data directly. As it turns out, HTML lets you jump out of a script block using no matter where you are in script. For instance, in the middle of a value in some JSON data we can jump out of script. But we still want to run script, so we can jump right back in. So the frame so far for the message we're going to post is the following:
