The private keys of eight eMudhra intermediate CA certificates, trusted by major root programs, have been compromised. Check whether your client is affected and how to protect it.
Update your stuff, folks. I’ve had a fun day at work.
They were proper 384bit certs, just the upper 376 bits were 0 in all the listed certs. So it’s different to setting the key size in OpenSSL, and they were most likely rolling their own crypto.
I’m honestly skeptical about even this. I tried to generate an 8 bit key and got
rsa_gen_set_params:key size too small.And like, you need to go deliberately out of your way to not use OpenSSL.
