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

The highlight of my recent trip to Europe was this conversation in the photograph above (also captured in this 360° video, and this audio recording).

The people in this photograph are participants from the Tunisian revolution in 2010, the Spanish 15M movement and the New Zealand Occupy movement in 2011, the 2014 Sunflower Movement from Taiwan, and Nuit Debout, the horizontal protest movement currently underway in France.

The recording is 3 hours long, so I've loosely transcribed it and cut it down into a couple of chapters:

	#!/usr/bin/env python3

	# 歸納法樣板
	class InductionProof:
	def induction(self, tabs, n):
	if n == 1:
	return tabs + self.base_case.replace("n", str(n))
	else:
	m = n-1
	inductive_hypothesis = "\n".join(tabs + s for s in self.induction(tabs, m).split("\n"))
