"Black Basta" is a new ransomware strain discovered during April 2022 - looks in dev since at least early February 2022 - and due to their ability to quickly amass new victims and the style of their negotiations, this is likely not a new operation but rather a rebrand of a previous top-tier ransomware gang that brought along their affiliates.
It posted no listings in the last 12 months.

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.
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.
