Spanish authorities had little control over much of the territory of Panama. Large sections managed to resist conquest and missionization until very late in the colonial era. Because of this, indigenous people of the area were often referred to as "indios de guerra" (war Indians) who resisted Spanish attempts to conquer them or missionize them. However, Panama was enormously important to Spain strategically because it was the easiest way to transship silver mined in Peru to Europe. Silver cargoes were landed at Panama and then taken overland to Portobello or Nombre de Dios on the Caribbean side of the isthmus for further shipment.
Panama is bounded to the north by the Caribbean Sea (an extension of the Atlantic Ocean) and to the south by the Pacific Ocean. It has an elongated S shape, with its Caribbean coastline stretching some 800 miles (1,290 km) and the Pacific coast some 1,060 miles (1,700 km); however, a line drawn from the Costa Rican frontier in the west to the Colombian border in the east would extend only 480 miles (770 km). The shortest distance across the isthmus is about 30 miles (50 km), from the mouth of the Nergalá (Necategua) River, which flows into the Gulf of San Blas on the Caribbean shore, to the mouth of the Chepo River on the Pacific coast. Nearly as narrow is the portion of the isthmus traversed by the Panama Canal.
Computer security expert Chris Kubecka announced May 24, 2016 that the Mossack Fonseca client login portal was running four different government grade remote access trojans (RATs). Kubecka confirmed there were still numerous critical vulnerabilities, too many open ports into their infrastructure and internet access to their archive server due to weak security. Kubecka explained how each data security issue was discovered in detail in a full-length book titled Down the Rabbit Hole: An OSINT Journey.
