Power Moendas Data Breach

Power Moendas, an organization located in Brazil, has been identified as a victim of the Arcus Media ransomware group. The claim was published on July 26, 2026, and brought to light through SOCRadar’s Dark Web Monitoring service. While the specific sector classification for Power Moendas is not detailed in the available data, its presence in Brazil is noted. Arcus Media is characterized as a low-volume ransomware operation with a smaller number of claimed victims observed over the past 60 days. Over the 60 days preceding this listing, Arcus Media has claimed only one other victim. This suggests it is a relatively new entrant to the ransomware leak-site landscape, rather than an established, high-volume threat actor. The limited victimology observed by Arcus Media primarily targets organizations in Brazil and Morocco. The Manufacturing sector appears to be the most frequently targeted industry identified so far. A comparable victim example is Brazer Ingenierie, an organization within the Manufacturing sector based in Morocco. Given the scarcity of data points, the listing of Power Moendas should be considered as part of an emerging pattern for Arcus Media, and any conclusions drawn about the group’s targeting profile should be made with caution.

SOCRadar’s analysis of stealer-log telemetry for the domain `powermoendas.com.br` returned no records of exposed credentials within the queried sample. The domain was specifically noted in the July 26, 2026 digest as having “no exposure in sample,” confirming it was explicitly checked. However, a null result from this query does not definitively indicate that the organization is unaffected by compromise. The query operates on a paginated sample, meaning it does not encompass every credential that may have been harvested. It is possible that Power Moendas utilizes alternative or subsidiary corporate domains that fall outside the scope of this specific search. Furthermore, credentials associated with personal email aliases, rather than official corporate ones, would not be captured in a search targeting corporate domains. The exposure of credentials harvested by infostealers is a well-documented pathway for ransomware operations. Threat actors or initial access brokers often acquire these credentials from underground marketplaces, test their validity, and then use them to gain access to systems via Microsoft 365, VPNs, or other remote-access portals before deploying ransomware. While this specific query yielded no matches, this scenario cannot be ruled out for Power Moendas. It is possible that matching credentials exist in data sources not covered by SOCRadar’s current dataset, or that credentials were used and subsequently rotated before they could be indexed. Additionally, credentials might have been harvested under personal email aliases, which would not be detected by a search focused on corporate domains. Given that the query returned no direct matches, the possibility of compromise through credential theft remains open. Organizations involved in monitoring threat intelligence, such as CTI teams, should maintain vigilance. This includes continuing dark web monitoring, conducting proactive credential-hygiene checks, reviewing password rotation policies, and examining multi-factor authentication configurations. Monitoring alternate corporate domains associated with Power Moendas and reviewing activity logs for Microsoft 365, VPNs, and remote-access portals are also recommended actions. Interpreting a null query result as definitive evidence of absence of compromise would be imprudent.
