Amv International Development Listed by The Gentlemen Ransomware Group

On September 9, 2025, the ransomware group known as thegentlemen added AMV International Development SA to its public leak site, claiming that it had exfiltrated internal files from the Colombian civil engineering and construction company.

What Public Reporting Shows

Public reporting indicates the company, which operates from Bucaramanga, Santander, Colombia, employs between 250 and 499 people and generates annual revenue between $10 million and $25 million. The victim’s website, www.amvsa.com, and its ZoomInfo profile were listed alongside the announcement. Available reporting describes the incident as a classic ransomware operation in which attackers gained access, stole data, and later published a sample on their onion site hosted at tezwsse5czllksjb7cwp65rvnk4oobmzti2znn42i43bjdfd2prqqkad.onion. No specific count of affected individuals has been disclosed, and the precise volume or sensitivity of the internal files remains unclear from current public information.

Why This Matters for You and Your Family

When a company like AMV International Development suffers a breach, the information inside its files often includes details that can be traced back to employees, contractors, suppliers, and their families. Names, addresses, national ID numbers, payroll records, or even children’s school information can appear in stolen spreadsheets. Once that data reaches a public leak site, anyone can download and repurpose it. For ordinary families, this means a higher risk of identity theft, fraudulent loan applications in your name, or targeted scams that reference real details about your work and household.

Credential leaks from corporate systems frequently cascade into personal account takeovers. If you or your family members used a company email address or reused a work password on personal services, the exposure creates a direct path for attackers to reach you at home.

The Doxxing and Identity-Chain Implications

Ransomware operators rarely stop at dumping raw files. They or subsequent buyers map relationships between corporate data and personal identities, linking work emails to home addresses, phone numbers, social-media handles, and even children’s gaming accounts. This creates an identity chain that can be exploited for doxxing, swatting, or sustained harassment. Public reporting on similar incidents shows that once initial data appears on a leak site, follow-on extortion attempts or sales on underground forums often follow within weeks.

Thegentlemen Group’s Public Track Record

Public reporting attributes thegentlemen as a ransomware group that emerged in late 2024. It has claimed responsibility for attacks on organizations across multiple countries, typically following a playbook of initial access through phishing or exploited remote-desktop services, followed by data exfiltration and extortion. The group posts victim data on its dedicated leak site after giving companies a payment deadline. Its operations focus on mid-sized businesses, and it has previously targeted firms in construction, manufacturing, and professional services. Exact success rates and total victims are difficult to verify, but its consistent presence on ransomware-tracking sites such as ransomware.live indicates an active and ongoing campaign.

What to do

• Run a DoxxScan to map every link between your work emails, personal handles, phone numbers, and real-world identity so you can see exactly what chains back to this claimed breach.
• Rotate any password you used at AMV International Development or related services anywhere it has been reused, and switch on two-factor authentication through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1 billion+ breach records and more than 100 platforms so the next exposure of your information is caught in hours instead of months.
• Cover the entire household with DoxxScan family protection, which extends to dependents and children’s gaming accounts that often become entry points in doxxing chains after credential leaks like this one.
• Let remediation specialists handle takedown requests across data brokers and leak sites on your behalf while you focus on securing your own accounts.

The incident underscores a simple reality: corporate breaches now routinely expose the personal lives of ordinary employees and their families. Taking deliberate steps to map and monitor your digital footprint can limit the damage before criminals turn stolen files into long-term threats. DoxxScan by GalaxyWarden delivers that protection through continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts.
