Good summary of an iCloud Keychain Secrets vulnerability (CVE-2017–2448). From the blog:
"This allows an adversary to craft an OTR message which can negotiate a key successfully while bypassing the actual signature verification...Considering that OTR uses ephemeral keys for encryption, this flaw implies that a syncing identity key is no longer required for an adversary with Man In The Middle capabilities to negotiate an OTR session to receive secrets."

Funny research paper co-authored by Daniel J. Bernstein, "Post-quantum RSA", explores potential "parameters for which key generation, encryption, decryption, signing, and verification are feasible on today’s computers while all known attacks are infeasible, even assuming highly scalable quantum computers".
Funny part is that the actual parameters are "really" practical. Example: "For the 2Tb (256GB) encryption, the longest multiplication took 13 hours, modular reduction took 40 hours, and in total encryption took a little over 100 hours."
