Today I'm disclosing several vulnerabilities I found in the certificate authority e-Tugra, which disclosed significant amounts of subscriber PII and may have impacted their certificate issuances. Hopefully other CAs are not like this! ian.sh/etugra

Security concerns with the e-Tugra certificate authority

If you need to get the signing time of a #PowerShell script, Get-AuthenticodeSignature doesn't do it & there doesn't seem to be a .NET way so here is a function from @Crypt32 that calls Windows API to get it & agrees with @SysInternals sigcheck sysadmins.lv/blog-en/retriev…

Every meeting of the flemish government in Belgium is live streamed on a YouTube channel. Software is searching for phones and tries to identify a distracted politician. This with the help of AI. The results are then posted to social with the politician tagged. By @driesdepoorter

It's nice to be recognized. In this case, Microsoft updated their Open Specifications documentation to point to our mskb archive as they no longer host the information needed. Nice work @crypt32. docs.microsoft.com/en-us/ope…. The link for [CertTransp] links to us now.

In other words, they are revoking just over 3 MILLION certificates in less than 12 hours. So we just need 252,000 certificates replaced each hour or 4,203 each minute or 70 certificates per second. When you put it that way, you're right, it's not that bad ;-)

On March 4, we will revoke 2.6% of currently active Let's Encrypt certificates. These certificates were affected by a compliance bug. Please see the details at: community.letsencrypt.org/t/…

[Update 2020-03-05: The most up-to-date summary is at 2020.02.29 CAA Rechecking Bug] Due to the 2020.02.29 CAA Rechecking Bug, we unfortunately need to revoke many Let’s Encrypt TLS/SSL certificates....
