DigiCert: Failure to supervise ABB Subordinate CA
This case involves DigiCert's failure to adequately supervise the ABB Subordinate CA, which resulted in delays in revoking approximately 500 misissued certificates. The issue was initially reported in a related bug, and despite DigiCert's acknowledgment and commitment to an accelerated replacement plan, progress was slow. Following discussions in the thread, DigiCert outlined a plan to improve oversight and communication regarding subordinate CAs. Ultimately, ABB CA 5 was revoked on August 28, 2019, and the incident has been resolved, although DigiCert continues to monitor the shutdown of other subordinate CAs.
