After discovering Felicity Smoak's hack of the Department of Education, Alena was inspired to become a hacktivist, going under the alias "Kojo Sledgehammer".

Member of Helix
Alena joined a hacktivist group known as Helix. In late 2016, they hacked ECHELON, the NSA's information-gathering program, drawing from it 8 petabytes of data, referring to it as "Pandora".

After Alena noticed someone who appeared to be Felicity Smoak hacking the NSA to no results, she contacted her via terminal message, offering her help. The two soon met in real life, Alena excited to meet her idol. She explained Felicity's inspiration to her, before handing her the USB flash drive containing Pandora, hoping to not only exonerate her friend but to inspire her to return to her hacking roots.
