<\/span>REMEDIATION PROTOCOLS AND HARDENING DIRECTIVES<\/span><\/h2>\nIf you want to survive the next 48 hours without the board of directors firing everyone in this room, you will follow these directives. This isn’t a suggestion. This is the only way forward.<\/p>\n
\n- \n
Identity Isolation:<\/strong> Every single Domain Admin account is compromised. Assume the NTDS.dit file is in the hands of the attacker. We are building a new forest from scratch. No migration. No “trusting” the old domain. We export the users to CSV, scrub them, and import them into a clean environment with Tiered Administration. Domain Admins only log into Domain Controllers. Period.<\/p>\n<\/li>\n- \n
Network Micro-segmentation:<\/strong> The flat network is dead. I want every department on its own VLAN. I want a Layer 7 firewall between the workstations and the servers. I want SSL inspection turned on. If a workstation tries to talk to a server on port 445, I want it blocked unless there is a documented business need.<\/p>\n<\/li>\n- \n
Endpoint Hardening:<\/strong> We are stripping local admin rights from every user. No exceptions. I don’t care if the CEO wants to install his own printer drivers. He can call the help desk. We are deploying EDR in “Enforcement Mode,” not “Audit Mode.” If it sees a suspicious PowerShell execution, it kills the process.<\/p>\n<\/li>\n- \n
True Immutability:<\/strong> We are purchasing a dedicated, air-gapped backup appliance. The backups will be written to physical tape and moved to a vault that is not connected to the internet. We will also implement S3 Object Lock in Compliance Mode<\/strong> with a 30-day retention period that cannot be bypassed by any user, including the root account.<\/p>\n<\/li>\n- \n
Vulnerability Management:<\/strong> We are moving to a 24-hour patching cycle for critical vulnerabilities. If a CVE with a score of 9.0 or higher is released, it gets patched that night. No “testing phase” that lasts three weeks. If the patch breaks the app, we fix the app. We don’t leave the door open because the rug is in the way.<\/p>\n<\/li>\n- \n
MFA Everywhere:<\/strong> Not just for the VPN. For every internal login. For every sudo command. For every access to the cloud console. If it doesn’t support MFA, we don’t use it. We are using FIDO2 hardware keys. No SMS codes. No “push to approve” that can be exhausted by MFA fatigue attacks.<\/p>\n<\/li>\n<\/ol>\nThe cost of these measures will be significant. The “business friction” will be high. But the cost of not doing this is what you\u2019re looking at right now: a server room full of expensive space heaters and a legal department that is currently hyperventilating.<\/p>\n
I\u2019ve spent the last two days looking at the wreckage of your company. The attacker spent $50 on a VPS and used free tools to dismantle a $500 million enterprise. They did it because you made it easy. You prioritized “seamless” workflows over security. You chose “vibrant” user interfaces over robust backend logic. You ignored the basics, and now the basics have ignored you.<\/p>\n
I\u2019m going home. My report will be uploaded to the secure portal\u2014the one that actually has a password. Don’t call me unless you’ve bought the hardware I listed in Appendix A. There is no “recovery” from this. There is only starting over.<\/p>\n
FINAL WARNING:
\nThe attacker still has your data. The ransom note was just the beginning. If you don’t change everything, they will be back in three weeks to see if you’ve learned anything. They won’t leave a note next time. They’ll just delete the partition tables and walk away.<\/p>\n
