Pulmonary Services Group Listed by The Gentlemen Ransomware Group

The Gentlemen ransomware-extortion group has listed Pulmonary Services Group on its leak site. The company has not publicly confirmed the claim as of writing. The filing, dated September 29, 2026, does not state how many people were affected and lists no specific categories of information.

If your records were included, the immediate risk is that an attacker now holds information that could be used for identity fraud or targeted phishing. Because no categories are disclosed, you cannot assume any particular data type is safe or exposed. What matters most is that any personal or medical-supply details tied to your account with the provider could be in play.

What a Leak-Site Listing Actually Establishes

Leak-site postings are claims made by the attacker, not independent verification. Ransomware groups frequently publish names of organizations to pressure payment, sometimes recycling old data, inflating claims, or listing targets they never fully compromised. The presence of Pulmonary Services Group on The Gentlemen’s page proves only that the group chose to list it. It does not prove a successful breach occurred, that any customer files were taken, or that the data is genuine.

Real confirmation would require an admission from the company, a regulatory filing detailing the scope, or direct notification to affected customers. Until then, this remains an unverified allegation. Treating every listing as proven fact gives attackers exactly the credibility they seek.

The Pattern Healthcare Providers Face

Smaller healthcare and home-medical-equipment providers in regional markets appear regularly on ransomware leak sites. The pattern reflects both attacker targeting of organizations that hold sensitive patient-adjacent records and the low cost of simply publishing a company name. Many listings later prove overstated or unconnected to any confirmed theft. For you, this means the next similar claim against a different provider should be approached with the same skepticism until independent evidence appears.

What You Can Still Control

Even without knowing exactly what was taken, several practical steps reduce downstream risk. Start by reviewing recent statements from Pulmonary Services Group for any unexpected charges or changes. Contact them directly to ask whether they have sent, or plan to send, a formal breach notification about this listing. Because the filing gives no incident date, the only reliable way to determine if you are in the affected group is through that direct communication.

If you have an online account with them, change the password as a low-cost precaution even though no credential exposure is confirmed. Monitor your credit reports and bank accounts for unusual activity in the coming months. Consider placing a fraud alert with the major credit bureaus if you notice anything suspicious.
