Amazon Informatica Ransomware Claim by emperador (Sep 2026)

Claim Summary

On September 28, 2026, a threat actor operating under the name “emperador” allegedly listed Amazon Informática LTDA on its dark web leak site. According to the threat actor, the Brazilian IT solutions integrator was purportedly breached, with the group claiming “full commitment of the network” and access to infrastructure and databases containing confidential and financial information.

Amazon Informática, founded in Brazil in 1995, is a technology integrator and managed services provider with a stated focus on public sector and government clients. The company reportedly maintains offices in Brasília/DF and Belém/PA, with additional operations in Latin America and Europe.

This claim has NOT been independently verified by Yazoul Security. The data volume was listed as undisclosed.

Threat Actor Profile

The ransomware group emperador is the entity behind this claim. Based on currently available intelligence, emperador has an unknown number of total known victims, and no known toolset has been publicly attributed to the group. There is no public research available on this actor at the time of writing.

This lack of a documented track record is significant. Unlike established ransomware operations with years of leaked data and confirmed attacks, emperador presents no verifiable history. Analysts should treat claims from low-profile or newly emerged groups with heightened skepticism, as such actors may exaggerate access or fabricate data to pressure victims into payment.

The group’s claimed tactics in this incident include credential harvesting from plaintext batch files and database cluster compromise. These claims remain unverified.

Alleged Data Exposure

According to the threat actor, the following categories of data were allegedly accessed:

• Production and integration databases with sensitive PII schemas
• Employee registries
• Banking credentials
• CPF and RG data (Brazilian national identity documents)
• Administrative master credentials reportedly exposed in plaintext within a file named get_bk.bat

The group claims to have compromised virtual infrastructure and database clusters. No data samples, download links, or proof files have been reviewed or verified by Yazoul Security. We do not publish or link to leaked data, credentials, or actor infrastructure.

If these claims are accurate, the exposure of CPF and RG data would carry significant regulatory implications under Brazil’s LGPD (Lei Geral de Proteção de Dados).

Potential Impact

If the claim is substantiated, potential impacts could include:

• Regulatory scrutiny under LGPD given the alleged exposure of Brazilian citizen identity data
• Contractual and compliance risk for a company serving government entities
• Operational disruption to managed services delivered to public sector clients
• Financial fraud risk if banking credentials were genuinely exposed

However, none of these outcomes are confirmed. Ransomware groups routinely overstate their access to accelerate victim response and payment.

What to Watch For

• Independent confirmation from Amazon Informática or Brazilian authorities
• Publication of verifiable proof by the threat actor, or absence thereof
• Any official notification to data protection authorities under LGPD
• Emergence of related activity or tooling attributed to emperador
• Whether the leak site listing is removed, updated, or left to expire

Organizations in the Brazilian government technology supply chain should review third-party risk exposure and monitor for credential reuse. Detection guidance specific to emperador is not currently available; standard ransomware detection practices apply.
