seems like this went unnoticed (if anyone posted sorry, I didn't see)

technically any cipher suite lower than 256bit (e.g. 128bit AES or w/o) are on risk (vulnerable aka dead)) get rid of anything RC4, MD5, SHA-1 and obscure etc.

time to toss away TLS 1.0 and also TLS 1.1 and use only TLS 1.2 (or 1.3 when it comes) !
get rid of weak and weird cipher suites !

and consider to deploy 'SameSite' set-Cookie header flag https://tools.ietf.org/html/draft-west-first-party-cookies-07#section-3.1

Thanks, Dwarden, for the heads-up on this one.

Another development for WordPress: https://en.blog.wordpress.com/2016/04/08/https-everywhere-encryption-for-all-wordpress-com-sites/
I'd rather would like to see a secure implementation of htps everywhere and we should really test at  https://www.ssllabs.com/ssltest/
The only advantage is admins can log-on somewhat more securely now.
Why the browser warns on a self-signed certificate and not for third party Let's Encrypt Certificates? Average users cannot distinct anymore between a real secure non-EV certificate and a Let's Encrypt 'toy'-one. And exploit attacks can now be performed over https-only.

Some tips to better protect your log-on credentials.
Admins should have two accounts, one for daily use and one for special tasks.
Memebers of Admin-groups should have zero permanent users and users with authentication should rotate to perform certain tasks.
Use 2FA to protect against Phishing Attacks that are after your credentials.
Administration should always be performed by users without full admin rights.
With rights there should be the possibility that such rights could be  withdrawn,
whenever such a task has been performed.
This is called Just in Time administration.
Applications should be performed according to a specific authentication role system.
Administration task should only be performed on high end security machines,
so-called dedicated systems.
A physical environment is always more secure than a virtual one.
There should not be browser hanging onto such a system or
there should be room to set up connections to or receive connections from internet addresses.
But also on the local user level the structures should be secure for exploit,
that may also endanger higher levels.

Tips from Roger A.Grimes.

Another Java Flaw (Java sandbox bypass) coming to revisit us after we met it in 2013, read: http://www.security-explorations.com/materials/SE-2012-01-IBM-5.pdf
Researcher Gowdiak writes that IBM old patch closed off the proof-of-concept attack without considering all possible code paths to the vulnerability.:
Quote
“There were no security checks introduced anywhere in the code. The patch primarily addressed the scenario illustrated by the Proof of Concept code. It didn't take into account all code paths that could be used to reach the vulnerable code sequence”,

2F Security, turn it on to keep hackers at bay even when they knew your password: https://www.turnon2fa.com/
But do not mark your device as trusted on websites that offer 2F protection. It might be more user friendly, but is not good protection-wise.
And when you loose your Android you never know whether it could become unlocked. In the worst scenario services will provide you with a back-up phone number to recover your account. Keep info you only know to claim your account back. Info credits: Lucian Constantin

P.S. The diasadvantage of 2F is that it can be used against you on certain occasions/circumstances  by authorities for instance, in that case there is nothing better than a really good strong old-fashioned password that you will keep to yourself. That is a decision you should make yourselves.

It's actually an old scam that's been around for quite q while.
1. don't click on links you don't know.
2. never download a player to watch something you didn't really ask for in the first place.
