It at least seems plausible it is based on the original. In 2011, Maks Velo, an Albanian painter and journalist, who was imprisoned in 1978 for "agitation and propaganda" against the Hoxha regime, gave an interview, where he commented on the role of Safo Marko as well as his own as witnesses in the prosecution of a Hysenil Dume. About Marko, he says:
E kam njohur Safo Markon qysh në vitin ’60. Shpesh uleshim e pinim kafe te klubi i shkrimtarëve dhe artistëve. Ishte një grua e respektuar gruaja e Petro Markos, e bukur, e mençur, e aftë. Ishte një nga ilustratoret më të mira të kohës, realizonte pllakate shumë të mira, madje ajo ka realizuar edhe pllakatin e Sigurimit të Shtetit me krahët e shqiponjës dhe syrin.

I have known Safo Marko since 1960. We often sat and drank coffee at the club of writers and artists. The wife of Petro Markos was a respected woman, beautiful, wise, capable. She was one of the best illustrators of the time, she created very good posters, and she even created the placard of Sigurimi with eagle wings and an eye. In short, she was an honored and respected colleague.
This would be a confirmation that Safo Marko was the author of the Sigurimi Logo, and the description roughly fits the picture.
That said, the description page on Wikimedia Commons says it is a "digital recreation" of the version shown at the BunkArt Museum, so it has certainly gone through multiple stages of re-drawing.
This page says Safo Marko received a Republic's Award ("Çmimi i Republikës") for an exposition poster for the 20th anniversary of the Armed Forces of the Security of State, ("Pllakat e ekspozitës me rastin e XX vjetorit të Armës së Sigurimit të Shtetit", hopefully I got the translation right). The only picture in connection with that anniversary I found is this, which at least tells that the anniversary was in 1963.
The poster itself I could not locate. But in 1983, the PPSH published a booklet for the 40th anniversary, and its cover shows this motive:
