Cracking the SS7 Network
NIST, the National Institute of Standards and Technology issued guidance that found SMS insecure and no longer suitable as a strong authentication mechanism...

I am using WebADM Multi-Factor Authentication with Hardware Token (U2F) and Hardware Security Modules (HSM) in order to comply with the highest security requirements...

This Security Solution from RCDevs is like a Swiss Army Knife.

It is even free up to 40 users.

That's not really cracking 2FA
Most of these aren't about cracking 2FA.  They are about bypassing 2FA.  The SS7 and SMS type examples could be argued as cracking, but they are really about breaking into SS7/SMS - the 2FA compromise is simply a welcome result or side effect. 

SMS is not secure and should never have been used for 2FA, but convenience wins (as the article points out).  Time based generators are much more secure (yep, and less convenient).

Phishing
As a Security Engineer, I always stress the dangers of phishing and this is a perfect example as to why. It subverts most of the security safeguards at an organization with minimal effort as it exploits an open medium. This is why there has been a very steady transition from server side attacks to client side attacks.
