- Allow scripts and macros only for users who need them, and keep behavioral rules enabled in endpoint protection.
- 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.
- 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.
