Manning Publications Co. Listed by Fog Ransomware Group

On March 5, 2025, Manning Publications Co. appeared on the leak site of the fog ransomware group. The company, known for its technical books and programming tutorials, is claimed to have had internal files exfiltrated during a ransomware attack. Public reporting indicates that customer and employee data may have been exposed, though the exact number of affected individuals remains unknown.

Reported Details of the Breach

The incident was first listed on the fog ransomware group’s dark web leak portal. Internal files were taken, and the group is using the typical ransomware playbook of encryption followed by data extortion. Available reporting describes the posting as part of a broader campaign that has hit other organizations in recent months. No confirmed total of records has been released, but the nature of Manning’s business means developer emails, purchase records, and contact information for authors and customers are likely among the stolen material.

Why This Matters for You and Your Family

When a publisher like Manning is breached, the information exposed often includes names, email addresses, physical addresses, and phone numbers tied to book purchases or account registrations. If you or anyone in your household has ever bought a Manning title, attended one of their webinars, or created an account on their site, your details could now be in attackers’ hands. Credential leaks like this one frequently cascade into account takeovers elsewhere because people reuse the same email-and-password combinations across services. Children who use family email addresses for online learning or gaming are especially vulnerable because a single leak can link their gaming handles back to your real identity and home address.

The Doxxing and Identity-Chain Risks

Ransomware groups rarely stop at publishing company files. Once internal documents are out, opportunistic criminals scrape them for personal data and begin building identity chains. A leaked customer record can be cross-referenced with gaming accounts, social-media handles, and data-broker profiles. This creates a map that lets attackers target you or your children with phishing, SIM-swapping, or direct doxxing. Public reporting indicates that fog and similar groups sometimes auction or freely distribute subsets of stolen data, accelerating how quickly your information spreads across underground forums.

Fog Ransomware Group’s Known Track Record

Public reporting attributes the fog ransomware operation to a group that emerged in 2024. It has claimed responsibility for attacks on a range of mid-sized businesses and publishers. The group’s typical playbook involves gaining initial access through compromised credentials or unpatched remote desktop services, exfiltrating data before encrypting systems, then demanding payment to prevent publication. Notable prior victims include other technology and education-related companies. The group posts samples and countdown timers on its leak site, a pattern consistent with the March 5, 2025 Manning listing.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, gaming handles, and real-world identity so you can see exactly what chains exist right now.
• Rotate the password you used on Manning Publications anywhere else it is reused, then enable 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information appears it is caught within hours instead of months.
• Cover the household with DoxxScan family protection that extends to children’s accounts and gaming profiles that often chain back to the same address or parent email.
• Let remediation specialists handle takedown requests across data brokers and suspicious sites while you focus on securing your own logins.
