Cleaver-Brooks, a Thomasville, Georgia-based manufacturer of industrial boilers and boiler room equipment, was reportedly named on a dark web leak site by a cybercriminal group known as Anubis in August 2026. The group claimed to have obtained company data, though Cleaver-Brooks has not publicly confirmed the incident and the specific categories of information involved have not been disclosed.
Companies that manufacture industrial equipment often maintain large amounts of sensitive data about their employees, customers, and business partners, and they have a legal and ethical responsibility to keep that information secure.
Cleaver-Brooks’s Data Breach Investigation
According to a dark web posting monitored by cybersecurity researchers, the ransomware group Anubis claimed responsibility for a cybersecurity incident involving Cleaver-Brooks. The claim was reportedly posted to a leak site in early-to-mid August 2026, with the underlying intrusion said to have occurred around August 10, 2026. As of this writing, Cleaver-Brooks has not issued a public statement confirming the incident, and the group behind the leak site posting did not disclose specific details about the volume or type of data it claims to have taken.
Ransomware groups like Anubis typically operate by infiltrating a company’s network, exfiltrating files before deploying encryption malware, and then threatening to publish stolen data on a leak site unless a ransom is paid. This extortion model means that even if a company avoids paying a ransom, previously stolen data can still end up exposed or sold to other bad actors. Manufacturing companies have increasingly become attractive targets for these groups because industrial firms often manage large employee and vendor databases while sometimes running older operational technology systems that can be harder to patch and secure than typical office networks.
Because Cleaver-Brooks has not yet confirmed which categories of personal information, if any, were accessed, it remains unclear whether the incident involved employee records, customer or vendor data, financial account information, or some combination of sensitive data types. Investigations into ransomware-related dark web postings like this one often take weeks or months to fully resolve, as companies work with forensic investigators to determine the scope of what was actually accessed before issuing formal notifications to anyone who may be affected.
In the meantime, individuals connected to Cleaver-Brooks as employees, former employees, customers, or business partners may want to stay alert for any official communication from the company and monitor their accounts for unusual activity, since dark web leak site claims sometimes precede a formal breach notification by a significant amount of time.
When Did This Breach Occur?
The Anubis group’s dark web posting referencing Cleaver-Brooks was tracked by cybersecurity monitoring services around August 10-11, 2026. Cleaver-Brooks has not publicly confirmed an exact date of intrusion or disclosed when the incident was first detected internally, so the full timeline — including when any unauthorized access may have begun and when the company itself became aware of it — is not yet publicly available.
What Information Was Breached?
The categories of information potentially involved in this incident have not been publicly disclosed. The Anubis group’s leak site posting did not specify what types of data, if any, were taken, and Cleaver-Brooks has not issued its own statement identifying affected data categories. Until the company or investigators release additional details, the specific personal information at risk — whether related to employees, customers, or business partners — remains unconfirmed.
