Leaker is a purported international hacker group referenced in connection with cyber incidents affecting the Paraguayan government in 2025. High-confidence public reporting only supports that the group was named as one of two other actor groups said to have hacked Paraguay within roughly a three-month period. No corroborated technical details are available in the supplied facts regarding Leaker’s tooling, intrusion methods, malware usage, operational scope, victimology beyond the Paraguay reference, organizational structure, aliases beyond the same name, or any confirmed relationship to ransomware, extortion, or state sponsorship. The currently available information is insufficient to attribute Leaker to a specific country of origin or to characterize its capabilities beyond alleged involvement in hacking activity.
