Details from the Leak Site
The primary disclosure on the Alphv leak site states that Grupo Garza Ponce suffered a ransomware attack in which internal files were exfiltrated. It lists the company headquarters address at 1000 Zaragoza 1, Monterrey, Nuevo León, along with its phone number and website. The posting does not detail the precise data types contained in the 2 TB of material, nor does it quantify how many customer, employee, or vendor records were affected. The leak site simply states that data was taken and threatens further publication if demands are not met.
Public reporting on Alphv, also known as BlackCat, indicates the group typically posts samples or countdown timers once initial extortion talks fail. In this case the listing appeared without an accompanying ransom amount, which is consistent with many Alphv entries that withhold full details until pressure escalates.
Why This Matters for You and Your Family
If you have ever worked with or hired Grupo Garza Ponce for construction, remodeling, or related services, your personal information may now sit inside the stolen files. Even when exact record counts remain unknown, construction firms routinely handle contracts that include full names, home addresses, phone numbers, email addresses, payment details, and sometimes copies of identification documents. Any of these can be used to open fraudulent accounts, file fake tax returns, or impersonate you in future dealings.
