Compania eMudhra a dezv\u0103luit detalii suplimentare legate de incidentul \u00een care opt certificate r\u0103d\u0103cin\u0103 ale autorit\u0103\u021bii de certificare au avut chei private u\u0219or de ghicit, av\u00e2nd doar 1 byte de entropie \u00een loc de 48. Pe l\u00e2ng\u0103 problemele ini\u021bial identificate cu certificatele intermediare r\u0103d\u0103cin\u0103, se raporteaz\u0103 despre revocarea altor 8, dar nu din cauza problemelor cu entropia. Analiza a ar\u0103tat c\u0103 sursa problemelor de entropie a fost un script Python creat manual, folosit pentru transferul cheilor private \u00eentre modulele hardware de stocare a cheilor (HSM) ale diferitelor m\u0103rci. Transferul cheilor a fost cauzat de \u00eent\u00e2rzierile \u00een livrarea modelelor avansate de HSM, care \u00eendeplinesc noile cerin\u021be pentru autorit\u0103\u021bile de certificare. <\/p>\n

Din cauza unei erori, dimensiunea cheilor private ECDSA a fost redus\u0103 la 1 byte. \u00cen plus, \u00een timpul transferului cheilor \u00eentre HSM, scriptul a procesat cheile private \u00een memorie volatil\u0103 neprotejat a computerului pe care a fost rulat, \u00een timp ce opera\u021biunile cu cheile private ar trebui efectuate doar \u00een interiorul HSM. Jurnalele HSM au confirmat c\u0103 modulele hardware au func\u021bionat corect, iar problema a fost cauzat\u0103 de utilizarea scriptului artizanal. <\/p>\n

Pe l\u00e2ng\u0103 cheile ECDSA, scriptul a fost utilizat \u0219i pentru transferul a 8 chei RSA-4096, care nu au avut probleme cu entropia, dar procesarea cheilor \u00een memoria obi\u0219nuit\u0103 contrazice cerin\u021bele de securitate impuse autorit\u0103\u021bilor de certificare, prin urmare, certificatele RSA au fost, de asemenea, revocate.
