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.
- Segment the network and expose management protocols only on the management network.
- Monitor large file archiving operations.
- 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.
