#1 TrickBot botnet survives takedown attempt, but Microsoft sets new legal precedent | 10.13.20
- The TrickBot botnet has survived a takedown attempt orchestrated by a coalition of tech companies on Monday. TrickBot command and control (C&C) servers and domains were seized and have been replaced with new infrastructure.
- Microsoft successfully argued in court against the use of Windows SDKs inside malware code. This is a precedent it will be able to use frequently in future botnet crackdowns.
- While the take down was described by the other companies involved as “temporal” and “limited”, it still marks a successful effort on the part of Microsoft and partners.

Lessons Learned From This Month’s Hacks
Small businesses, especially in the healthcare industry, have never been more attacked by cybercriminals. At a minimum, you must be applying Windows Security Updates RELIABLY to every Windows device every month. Also, it would be best if you had an IT resource that keeps up with current trends via Reddit (/r/sysadmin), ZDNet, ASCII, and other sources regularly.
Ask yourself:
Does my internal IT resource have time or the wherewithal to keep up with this amount of information?
Does my one-man IT Guy have the resources?
Does my IT Company?
Start with asking questions and reference the third article regarding the Netlogon exploit (more info here). How long did it take for your IT resource(s) to patch AND update the group policy on your Active Directory environment?
Many small businesses are operating with this vulnerability even today — they lack sufficient IT resources and have no clue about the danger. If you have not heard a peep from your IT resource regarding the Netlogon exploit, email them ASAP and ask if the recent Netlogon flaw applies to you, and if so, what have they done to mitigate it.
