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?
