RC4 Only servers fall below 1% – June 2014 scan results

Another month, another set of results. This month’s big news is the percent of servers that support only RC4 ciphers has fallen below the 1% mark!

Note that this set is compared to the just now published results of SNI-enabled scan from last month not the results published a month ago!

The general choice of block ciphers haven’t changed much, AES-GCM has grown a bit (by 1.2%), the cipher of choice for the Internet is still AES (at over 93%).

Percent of servers with misconfigured cipher suites haven’t changed much, AECDH have grown by little bit (by 0.19%).

Number of servers that support PFS is steadily growing, with DHE gaining nearly 0.5% and ECDHE gaining 1.2%. Number of servers that prefer the weak 1024 bit DH parameters has also fallen by over 0.5%. So not only we’re getting new properly configured servers but also older ones are updated to support the more secure and faster ECDHE with 256bit curves!

Unfortunately, it looks like the sudden increase of SHA-256 signed certificates is over and we’re back to the steady, slow increase. This month it has grown by 0.9%.

The kind of keys that are being signed haven’t changed significantly. 2048bit RSA is still the key size of choice for over 95% of server admins.

Also, the number of servers that support only SSLv3 has fallen below 1% mark, it’s at 0.993% now. Unfortunately, the number of servers that support TLSv1.2 has increased only by 1.65%.

Mozilla recommends disabling RC4

Mozilla currently recommends using 3DES ciphers instead of RC4 for backwards compatibility with very old systems like Android 2 or Internet Explorer on Windows XP.

The current recommendation comes after similar recommendations from researchers that discovered the most recent flaws in it, Cisco, Microsoft and their proposition to IETF as well as Qualys and Bruce Schneier.

The message is clear: don’t use RC4.

If you had for some reason follow the Mozilla guide, you don’t have to use this insecure, nearly 30 year old cipher any more. While you’re changing the cipher suite defaults, consider also updating to Perfect Forward Secrecy capable configuration.

TLS 1.2 adoption half way mark reached! May 2014 cipher scan results

Update: previous version of results counted “broken” cipher suites (export, ADH, AECDH) even if server didn’t have a trusted certificate.

I’ve scanned Alexa Top 1 million sites again and this month’s results results are both depressing and encouraging.

The bad

Number of sites that force RC4 in TLS 1.1 and TLS 1.2 connections has grown (by nearly 1.5%). The percent of sites that accept export grade cryptography or plain broken cryptography hasn’t changed significantly.

The good

Fraction of servers that support only RC4 ciphers has fallen by 0.4% to 1.38%. More and more certificates are using the SHA-256 based signatures (now over 10%, an increase by nearly 5%).

Interestingly, there are first sites that use only ECDSA certificates (at the moment 2).

Also, we’ve finally reached the half way mark for TLS 1.2 adoption on the servers. Over 54% of servers support TLS1.2 and over 51% support TLS1.1.

Scan performed between 7th and 15th of May 2014.

Cipher scan results in April 2014

Update: The previous version of the tool incorrectly counted broken cipher suites (export, ADH, AECDH).

I scanned Alexa top 1 million sites between 5th and 17th of April 2014 and found out that many servers still not only are badly configured (prefer RC4 ciphers) but won’t negotiate with safely configured browser (one that does not support RC4).

 

SSL/TLS survey of 305280 websites from Alexa's top 0.97 million
Stats only from connections that did provide valid certificates
(or anonymous DH from servers that do also have valid certificate
installed)
