NOTICE:

• The zip archives on this page have been updated, and they now use the new password scheme.  For the new password, see the "about" page of this website.

NOTES:

• In the reference below, I mistakenly reported the BackConnect and Dark Cat VNC traffic as "DarkVNC" for @Unit42_Intel.
• I've fixed this blog post and the material to show the correct activity.
• For more on Backconnect, see: https://www.netresec.com/?page=Blog&month=2022-10&post=IcedID-BackConnect-Protocol
