LCM Construção e Comércio S/A Listed by nova Ransomware Group

On July 11, 2025, Brazilian construction firm LCM Construção e Comércio S/A appeared on the leak site of the nova Ransomware Group, with the attackers claiming to have exfiltrated internal company files during a ransomware incident.

Reported Details from Reports

Public reporting indicates the company, which specializes in engineering and construction projects, had sensitive internal documents taken. The nova group posted proof of the breach on its dark-web leak site, a common tactic used to pressure victims. No specific count of affected individuals has been disclosed, and the precise volume or nature of the files remains unclear beyond the broad description of internal records. The listing carries a typical extortion timeline, although exact deadlines have not been independently verified in open sources.

Why This Matters for You and Your Family

When a company that handles contracts, employee records, vendor details, or client information is breached, the ripple effects often reach ordinary people. If you or anyone in your household has worked with a construction or engineering firm like LCM Construção, your name, address, contact information, or financial details could be among the stolen data. Once exposed, this information rarely stays contained. It can appear on multiple underground marketplaces within weeks, giving identity thieves, scammers, and harassers easy starting points. For families, the exposure frequently extends beyond the primary victim to spouses, children, or other relatives listed in employment or insurance files.

The Doxxing and Identity-Chain Risk

Stolen internal files frequently contain more than names and addresses. They can include email accounts, phone numbers, project references, and even notes that link personal identifiers to usernames used on social media or gaming platforms. These connections create what security analysts call an identity chain. A single leaked work email can lead attackers to personal accounts, password-reset links, and eventually full account takeovers. Credential leaks like this one cascade into gaming account takeovers, especially when children use family email addresses or shared phone numbers for Roblox, Fortnite, or other platforms. The result is doxxing that can expose your home address, family photos, and daily routines.

Nova Ransomware Group's Known Activity

Public reporting attributes the nova Ransomware Group with operations that emerged in recent years, focusing on mid-sized companies across multiple countries. The group typically gains initial access through common vectors such as phishing or unpatched remote desktop services, exfiltrates data before deploying ransomware, and then follows a double-extortion playbook: demanding payment to prevent file encryption and a second payment to stop publication of the stolen information. Notable prior victims have included organizations in manufacturing, logistics, and professional services, though exact details vary across incident trackers. The group's leak sites are used to publicly shame non-paying targets, a pattern consistent with many contemporary ransomware operators.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real-world identity so you can see exactly what this claimed breach may have exposed.
• Rotate any password used at LCM Construção or related vendor portals anywhere it has been reused, and switch on 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next leak that touches your family is caught and addressed in hours instead of months.
• Cover the entire household with DoxxScan family protection, which includes children's gaming accounts that often chain back to the same addresses or parent emails exposed in corporate files.
• Let remediation specialists perform hands-on takedown work across data brokers and leak repositories while you focus on securing day-to-day accounts.
