A vulnerability (CVE-2017-15361) in generation of RSA keys used by a software library adopted in cryptographic smartcards, security tokens and other secure hardware chips manufactured by Infineon Technologies AG allows for a practical factorization attack, in which the attacker computes the private part of an RSA key. The attack is feasible for commonly used key lengths, including 1024 and 2048 bits, and affects chips manufactured as early as 2012, that are now commonplace.

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."
