Ministry of Defense of Peru Listed by ransomexx Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On March 24, 2024, the Ministry of Defense of Peru was listed by the ransomware group ransomexx. The group claims to have exfiltrated internal files totaling 763.8GB during a ransomware attack. The number of people affected is unknown, and independent confirmation of the incident remains limited to the group's public listing.

As the government body responsible for Peru's defense and security affairs, any claimed compromise of its systems carries potential implications for national operations and personnel, even while many specifics stay undisclosed.

Breaking down the breach

Public reporting states that the Peruvian Ministry of Defense (Ministerio de Defensa del Perú) appeared on the ransomexx leak site on March 24, 2024. The group asserts that internal files were taken in a ransomware attack and lists the volume of data as 763.8GB. No further details on the date the intrusion began, the entry method, whether systems were encrypted, or whether a ransom demand was issued have been made public. The number of individuals whose information may have been involved is unknown.

The listing itself constitutes the group's claim; it has not been independently verified in available records. Exact technical indicators, timelines, or remediation steps taken by the ministry are undisclosed.

Inside ransomexx

Ransomexx is a ransomware operation known for double-extortion tactics. The group typically gains access to networks, exfiltrates data, and encrypts systems before demanding payment, then publishes stolen material on a dedicated leak site if the demand is not met. It has previously targeted large organizations across government, manufacturing, and other sectors, often advertising multi-gigabyte data sets. In this instance the group claims the Ministry of Defense of Peru as a victim and lists an asserted data volume of 763.8GB; no additional statements specific to this victim beyond that listing appear in the available facts.

Like other ransomware actors of its type, ransomexx relies on public pressure created by the threat of data release. Its operations are well-documented in cybersecurity reporting, yet each listing remains an unverified claim until corroborated by the victim or independent analysis.

About Ministry of Defense of Peru

The Ministry of Defense of Peru is the central government agency charged with overseeing the country's defense and security affairs. It coordinates military policy, armed-forces administration, procurement, and related national-security functions. Entities of this kind routinely manage personnel records, operational planning documents, communications, and other internal materials that support defense readiness.

A claimed breach at such an institution is consequential because the data it holds can touch both individual service members and broader strategic interests. Even when the precise impact is unconfirmed, the sensitivity of the sector elevates the potential stakes for operational security and public trust.

The information in question

The available facts describe the exposed material only as "internal files" exfiltrated in a ransomware attack, with a claimed volume of 763.8GB. No further breakdown of file types, categories, or specific records has been disclosed. Defense ministries typically maintain personnel data, administrative records, logistical information, and operational documents; however, whether any of those categories were present in the claimed exfiltration remains unconfirmed.

Public detail on the exact contents is therefore limited. Readers should treat any assertion of specific data elements beyond the stated "internal files" as unsupported by the current record.

What's at stake

For individuals whose information may have been among the internal files, risks include potential misuse of personal details for phishing, identity fraud, or targeted social engineering. Because the number of affected people is unknown and the precise data types are undisclosed, the concrete exposure for any single person cannot be quantified from public sources.

For the ministry itself, the claimed release of internal material could complicate operational security, strain resources needed for investigation and recovery, and affect confidence in the handling of sensitive government information. These outcomes remain contingent on what was actually taken and whether the data is published—facts that have not been independently established.

What to do if you're exposed

If you have reason to believe your information may have been involved, begin by monitoring bank and credit accounts for unusual activity and place fraud alerts if warranted. Change passwords on any accounts linked to government or defense-related services and enable multi-factor authentication wherever available. Treat unsolicited emails or messages that reference the incident with caution, as they may be opportunistic scams.

Readers can also run a free exposure scan of their email address to check whether their information has already appeared in known breach data sets. Official guidance from Peruvian authorities, if issued, should be followed for any additional steps specific to this event.
