Malware Based Revocation Ballot

• Ballot summary
  • Taking approach BRs and SBRs are taking on revocation
  • Removing CS specific suspect code reference
  • Discuss 5 day revocation window, consider a 5 day and/or 7 day
• Bruce noted good to sync with the SSL BRs at 24 hours and 5 days, but ok with suspect code at 5 days and 7 days
• Discussion if we should have requirements defining a misused certificate compared to private key misuse
• Additional discussion of misused keys, compared to compromised keys, and signed code that is suspect
• Action point to consider defining misuse
• Discussion on proper time limit for known compromise and signing malware
• Discussion of the difference in timing requirements between key compromise and singing suspect code and back dating revocation
• Discussed the consideration that signing suspect code should be treated as a potential compromise of key and/or the subscriber does not have practices in place to detect suspect code
• Discussion of asking Microsoft as the main certificate consumer to weigh in on complicated use cases. This is a practice now and not an overly common practice, this would take place after revocation and there is an open period to back date revocation
• Mentioned the RFC does not allow back dating, but it is an important tool for code signing
• Need to cover the loophole for certificate problem reports for expired or revoked certificates
• Potential wording is being drafted and will be included in GitHub and distributed

Other topics

• It was determined singing service did not have much to discuss at this time and we should focus on the revocation topic
• A couple of points on removing the SSL BR reference were mentioned and would be discussed on future calls
