Which defenses matter most?
Priority defenses based on the documented techniques:
- Keep internet-facing VPN, remote desktop and firewall interfaces patched, and require multi-factor authentication on these accounts.
- Allow scripts and macros only for users who need them, and keep behavioral rules enabled in endpoint protection.
- Monitor newly created services, scheduled tasks and startup entries.
- Reduce local administrator accounts and perform privileged tasks from separate, monitored accounts.
- Alert when security software is disabled or logs are cleared.
- Regularly check whether employee passwords and session cookies appear in infostealer logs.
- Monitor accounts that run many queries in a short time and unusual network scans.
- Segment the network and expose management protocols only on the management network.
- Monitor large file archiving operations.
- Block unapproved use of remote management tools.
- Monitor unusual data volumes sent to cloud storage and file transfer services.
- Keep offline, immutable backups and test restores regularly.
What should you do if your organization is listed on a leak site?
- Record the listing and any published sample files; do not visit the leak site from the corporate network.
- Isolate affected systems and preserve logs without deleting them.
- Determine which data left the organization; if personal data is involved, review notification obligations with your legal team.
- Make any decision about the ransom demand together with legal, management and incident response.
- Do not bring systems back online before the attacker’s entry point is closed.
