Linney Listed by Dunghill Ransomware Group

On March 20, 2025, marketing services firm Linney appeared on the leak site of the dunghill ransomware group, with the attackers claiming to have exfiltrated internal files during a ransomware incident.

What Public Reporting Shows

Public reporting indicates that dunghill posted details about Linney on its dark web leak portal. The company, a sixth-generation multichannel marketing group, provides services including graphic design, brand strategy, copywriting, social media campaigns, website development, data analysis, content scheduling, prototyping, eCommerce integrations, video production, and analytics. Linney has managed marketing campaigns inside McDonald’s restaurants for more than a decade and was preparing a spring 2025 campaign for Starbucks at the time of the incident. The exact number of people whose information may have been exposed remains unknown, and the specific types of internal files posted have not been independently verified beyond the group’s claims.

Why This Matters for You and Your Family

When a company like Linney that handles marketing, data analysis, and client campaigns is breached, the information inside its systems can include customer records, contact details, campaign briefs, and other personal data tied to everyday consumers. Internal files exfiltrated in ransomware attacks often contain spreadsheets, contracts, email archives, or databases that list names, addresses, phone numbers, or email accounts. If your family has interacted with McDonald’s or Starbucks promotions managed by Linney, or if you have ever been part of a brand survey, loyalty program, or promotional campaign, your information could be among the records now in attackers’ hands. Once stolen, this data rarely stays contained; it circulates on underground forums and can be used for identity theft, phishing, or sold to other criminals.

The Doxxing and Identity-Chain Implications

Ransomware leaks like this one frequently expose more than isolated records. A single email or phone number can link to your social media handles, gaming accounts, family member profiles, and even children’s online identities. Attackers and subsequent buyers map these connections to build complete identity chains that lead to doxxing, targeted scams, or account takeovers. Credential leaks from marketing databases often cascade into gaming platforms because families reuse passwords across work, personal, and children’s accounts. A breach at a company handling brand campaigns can therefore ripple outward, exposing your household far beyond the original incident.
