Listing text
Greentech Environmental LLC, a manufacturer of air purification systems using patented ODOGard and ARC technologies, has failed to fully secure and address the breach, and therefore we are publishing their confidential information such as (intellectual property/trade secrets, financial statements, employee data, operational/strategic plans, legal documents, corporate governance documents, and manufacturing drawings) that would violate the Defend Trade Secrets Act (CFAA) and state privacy laws, which would subject us to injunctive relief, treble damages, penalties, mandatory notification, class action lawsuits, loss of patent rights and competitive advantage, and possible business failure.

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?
