Mielke oversaw this organization's most successful operation, the placing of Gunther Guillaume in the entourage of Willi Brandt, as well as the development of a vast network of informants in his decades of authority.
Karlheinz Kurras was a member of this organization, and its first director was Wilhelm Zaisser, who had previously been the commander of all pro-Republican international forces in Spain after 1937. His tenure in charge of this organization ended after an uprising in 1953, when he was succeeded by Erich Mielke, his deputy, who was imprisoned decades later for a murder he had committed as a (*) KPD thug. That uprising ironically served to strengthen the regime of Walter Ulbricht. Mielke oversaw this organization's most successful operation, the placing of Gunther Guillaume in the entourage of Willi Brandt, as well as the development of a vast network of informants in his decades of authority. For 10 points, name this organization, the domestic security agency of East Germany.
