Introduction to Ransomware

Q:  What is Ransomware?

  • Ransomware is malware that encrypts files on your computer, afterword leaving you with instructions on how to pay for the encryption key to decrypt your files.

Q:  How do you restore your data if you are infected with Ransomware?

  • It is not likely you will find a tool to decrypt your files.  The encryption often used is RSA-1024 or 2048.
    • Mathematicians estimate that with the aid of super-computing clusters of 1,000 cores, they may be able to break RSA-1024 encryption in the year 2020.
  • Many victims were not provided with a working solution to restore their data even after paying the ransom
  • Your most reliable method for recovery is restoring from off-premise, or cloud-based backup solutions.

Firewall considerations for Autodesk Licensing

LMTOOLs consists of two utilities that need the following ports opened:

  • "lmgrd.exe" needs incoming TCP on ports 27000-27009
  • "lmtools.exe" needs TCP on port 2080

Standalone License activation happens on port 443 to "registeronce.autodesk.com"

For troubleshooting of LMTOOLs network licensing, we recommend using Wireshark which can be downloaded here.

Sample syntax for your capture filter:
(tcp.port==2080)||(tcp.port>=27000)||(tcp.port<=27010)
