grupo-principal.com Listed by apt73 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
grupo-principal.com has been listed by the apt73 ransomware group, with internal files reported exfiltrated in the attack. The incident was disclosed on April 27, 2026, affecting an undisclosed number of people; anyone who may have shared data with the organisation should review their accounts and monitor for unusual activity.
What happened
The incident came to public notice through apt73’s listing of grupo-principal.com. The group claims to have obtained internal files in the course of a ransomware operation. No additional details on the date of the intrusion, the volume of data taken, or the method of initial access have been made public. The company has not issued a statement confirming or disputing the listing.
Who is apt73?
apt73 is a ransomware operator that maintains a public leak site to pressure victims. Groups of this type typically encrypt systems and copy files, then publish samples or lists of victims when negotiations fail. Their listings serve as an unverified claim of access; independent confirmation of the underlying breach is not provided by the group itself.
Who is grupo-principal.com?
Grupo Principal operates as a distribution company in Mexico focused on fast-moving consumer goods. Firms in this sector manage supply chains that connect manufacturers with retailers, handling logistics, inventory records, and commercial agreements. A compromise at such an organisation can touch data belonging to multiple downstream businesses and their customers.
The information in question
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of specific file types or data categories has been released. Organisations of this kind routinely store supplier contracts, sales records, logistics documentation, and employee or partner contact details; whether any of these categories were among the files taken is unconfirmed.
What's at stake
Exposed internal files can reveal operational relationships, pricing structures, and contact information that may be used for targeted follow-on activity. If personal data of employees or business partners is present, those individuals face risks of phishing or account misuse. The absence of a confirmed data count leaves the scale of potential impact unknown for now.
If your data was in this claimed breach
Monitor accounts tied to any email addresses or identifiers you have shared with Mexican distributors or retailers. Enable multi-factor authentication on those accounts and review recent login activity. A free exposure scan of your email address against known breach repositories can show whether your information has already appeared in public data sets from prior incidents.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
