Zef Cekaj

Zef Cekaj is a security researcher specializing in vulnerability reversing and discovery. He has reversed and documented hundreds of vulnerabilities and has a history of vehemently arguing with vendors over email regarding exploitability of bugs in their products. Consequently, he enjoys winning such arguments by demonstrating exploits on live systems.

His primary interests are in the exploitation of server side vulnerabilities and mitigation circumvention. He is currently researching identified vulnerabilities in popular sandboxing implementations so that he may contribute to The Movement to Liberate Shellcodes (, of which he is a founder.
