About the group
blackbasta posted its first listing on Apr 26, 2022 and has listed 523 organizations to date.
"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.

What does this listing mean?
Ransomware groups move data out of the organization before encrypting systems and threaten to publish it if the ransom is not paid. This method is called double extortion.
The listing shows that the group claims to have targeted the organization. Whether the data was published is shown by the later status of the listing.
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.
