WannaCry|WannaDecrypt0r NSA-Cyberweapon-Powered Ransomware Worm

• Virus Name: WannaCrypt, WannaCry, WanaCrypt0r, WCrypt, WCRY
• Vector: All Windows versions before Windows 10 are vulnerable if not patched for MS-17-010. It uses EternalBlue MS17-010 to propagate.
• Ransom: between $300 to $600. There is code to 'rm' (delete) files in the virus. Seems to reset if the virus crashes.
• Backdooring: The worm loops through every RDP session on a system to run the ransomware as that user. It also installs the DOUBLEPULSAR backdoor. It corrupts shadow volumes to make recovery harder. (source: malwarebytes)
• Kill switch: If the website www.iuqerfsodp9ifjaposdfjhgosurijfaewrwergwea.com is up the virus exits instead of infecting the host. (source: malwarebytes). This domain has been sinkholed, stopping the spread of the worm. Will not work if proxied (source).

update: A minor variant of the viru

(Tested with KeePassXC on Fedora 25)

By default when using GNOME Keyring you have a keyring that is unlocked when you log in (usually called "Login"). You can make use of that by storing a KeePass database password in this keyring and using it to automatically unlock your KeePass database.

Store the KeePass database password in GNOME Keyring. You'll have to set a label and at least one attribute/value pair. The label is displayed in a GNOME keyring manager (e.g. Seahorse), the attribute/value pair should be a unique identifier because it's needed for the lookup. I suggest to use keepass as attribute and the database name as value (make sure it doesn't contain any spaces).

secret-tool store --label="KeePass <database_name>" keepass <database_name>

Then create a script to launch and immediately unlock your KeePass database.

You do not need a separate /boot partition unless you have an LVM setup (used in dm-crypt setups).

Run ubiquity -b to open the installer with the option of skipping grub installation (since we're using systemd-boot).

When you get to the screen "Ubuntu has finished installation" choose Continue testing.

Open a Terminal.

Chroot into the new system.

This guide offers the least time-consuming way of setting up Nginx for serving Git repositories over HTTP using Gitweb. The stuff here has been tested with Git 1.9.1 and Nginx 1.6.0 on Debian Wheezy. Probably also works for Ubuntu, etc.

Total time ~ 10 minutes.

Install

Enable wheezy-backports by adding this line to /etc/apt/sources.list:

deb http://http.debian.net/debian wheezy-backports main

Generic Trie in Swift

This is an attempt to implement a trie in Swift with a generic key. Instead of using just strings as keys, this trie can be keyed by any object that can generate its own prefixes. This is accomplished by using a protocol to define a trie key that can return a generator of Hashables. We need Hashables because the prefixes will be stored in a Dictionary.

Defining the Key Type

The TrieNode class will be a private implementation detail. It helps to separate the implementation into TrieNode and the wrapper for a few reasons:

1. If we want to extend the trie to implement some common Swift collection protocols, many of those don't make sense for every node.
2. We want references for nodes but the wrapper struct can help us simulate value semantics.
