Na Ọktọba 2017, ndị nchọpụta nchedo chọtara nsogbu (nke a maara dị ka ROCA) na mmejuputa RSA keypair generation na cryptographic library nke ọtụtụ Infineon nchekwa ibe na-eji. Ọdịdị ahụ na-enye ohere ka onye na-awakpo wughachi igodo nzuzo site na iji igodo ọha. Ihe niile YubiKey 4, YubiKey 4C, na YubiKey 4 Nano ngwaọrụ n'ime nyocha 4.2.6 ruo 4.3.4 emetụtawo nsogbu a. Yubico doziri nsogbu a na ngwaọrụ YubiKey 4 niile site na ịgbanwee gaa na isi ọrụ dị iche iche ma nye ndị nnọchi n'efu maka igodo ọ bụla emetụta. Onyinye nnọchi ahụ kwụsịrị na March 31, 2019. N'ọnọdụ ụfọdụ, enwere ike ịhapụ nsogbu ahụ site na ịmepụta igodo ọhụrụ n'èzí YubiKey ma bubata ha na ngwaọrụ ahụ. Ajụjụ: ebee ka ndị nchọpụta nchedo ROCA hụrụ nsogbu October 2017?
