2021-12-10 (FRIDAY) - TA551 (SHATHAK) ICEDID (BOKBOT) WITH BACKCONNECT, COBALT STRIKE AND ANUBIS VNC

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 Anubis 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
• For more on Anubis VNC, see: https://blog.nviso.eu/2023/03/20/icedids-vnc-backdoors-dark-cat-anubis-keyhole/
