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).

Two ways to do it, but only worked for me so I'll put it first and the second for reference:

$ openssl pkcs12 -export -in hostname.crt -inkey hsotname.key -out hostname.p12
$ openssl pkcs12 -in hostname.p12 -nodes -out hostname.pem

Other options for this method in comments below:

# Note, the -certfile root.crt appends all CA certs to the export, I've never needed these so it's optional for my personal steps
$ openssl pkcs12 -export -in hostname.crt -inkey hsotname.key -certfile root.crt -out hostname.p12

Note, I've always had my hostname.crt as part of my .pem, so I keep my certs but apparently you may not have to, hence the nocerts flag being an extra option in this sample
