DELTADENTAL.COM Listed by clop Ransomware Group

On June 29, 2023, Delta Dental’s corporate domain deltadental.com appeared on the leak site operated by the Clop ransomware group. The listing states that internal files were exfiltrated during a ransomware attack. The disclosure does not specify the number of people affected, the exact volume of data taken, or the types of records involved beyond “internal files.” Anyone who has ever received dental insurance through Delta Dental, submitted a claim, or had their employer contract with the company may have information now in the hands of extortionists.

Reported Details from the Listing

The Clop leak site entry, still accessible via the onion address indexed by ransomware.live, claims that Delta Dental was compromised and that attackers successfully removed internal files. No sample data has been published publicly on the site, and the group has not posted a specific ransom demand or deadline in the visible listing. The notification does not quantify affected records or name particular systems beyond the corporate domain. These sparse but official details from the primary extortion page are the sole authoritative source for what is known about the breach itself.

Why This Matters for You and Your Family

Dental insurers hold sensitive personal information that many people overlook. Claims often contain Social Security numbers, dates of birth, addresses, phone numbers, email addresses, and detailed treatment records. When such data leaves a company’s control, it can be used to file fraudulent tax returns, open accounts in your name, or build a profile for more targeted scams. Because dental coverage is frequently provided through employers, entire households can be exposed from a single breach. Even if you do not remember interacting directly with Delta Dental, dependent coverage or spousal plans may have placed your family’s details in the compromised environment.

The Doxxing and Identity-Chain Risk

Stolen internal files frequently contain spreadsheets that link employee or customer identities to email addresses, usernames, and sometimes passwords or password hints. These fragments become the starting point for doxxing chains. An attacker who obtains your work email from the Delta Dental files can test that same email on gaming platforms, social media, and financial services. Once one account falls, the attacker can reset others, harvest more personal data, and eventually tie your real name, address, and family members together. Credential leaks like this one cascade into account takeovers that affect both adult users and children’s gaming accounts that share the same household email or phone number.

Clop’s Publicly Known Track Record

Public reporting attributes the first major activity of Clop (sometimes stylized as Cl0p) to 2019. The group rose to prominence in 2021 and 2022 after adopting the “double extortion” model of encrypting victim networks while simultaneously exfiltrating data for later public shaming. Notable prior victims include large insurers, financial service firms, and healthcare-related organizations. Clop’s typical playbook begins with exploitation of vulnerable internet-facing software—most famously the MOVEit file-transfer vulnerability in 2023—followed by rapid exfiltration of internal shares and databases. The group then posts teaser messages on their leak site and waits for payment. If no payment arrives, they publish or sell the data. The Delta Dental listing fits this established pattern exactly.

• Cover the household—DoxxScan family coverage extends to dependents and children’s gaming accounts that often chain back to the same address or parent email.
• Let the remediation specialists handle ongoing takedown requests across data brokers and extortion sites for you.
