Storing passwords, a brief recap:

* 1990: Just put them into a database.
* 1995: You gotta MD5 those bro, plain-text is not good.
* 1996: I heard MD5 is no good anymore, better SHA-1 one those.
* 1997: Better add a sleep delay to slow down brute-forcing through remote connections.
* 1998: Add a salt, bro, beware of dictionary attacks. One per database should be enough.
* 2000: Sorry, I meant a unique salt per password. There is this thing called rainbow tables now.
* 2005: SHA-1 is broken too now, we need to migrate to SHA-256.
* 2010: Forget about SHA-256, we need to deal with GPU crackers now. Let's just key-stretch for now.
* 2014: Our homegrown key-stretching algorithm turned out to be a massive failure. Let's just switch to scrypt.
* 2015: OK, our data at rest is safe (for now) but our user passwords still made it to pastebin because we decrypt everything in RAM and hackers dumped everything from there.

COMPUTERS WHYYYYYYYYYYYYYYY

The operating system I was using in 1978 was using encrypted passwords with multiple salts.

I don't usually overtly promote Sophos stuff, but I am in love with the #Sysmas campaign. Anyone who has ever worked in IT can empathize.

The Xbox One seems to only be partially baked. Feels like a rush job.

Is there a better way to celebrate Autumn than fresh sour dough and some spiced cider?

Apply the Fix it now... Or do what I do and stop using IE. Friends don't let friends use Internet Explorer.
 
Attention Internet Explorer users (and administrators). There is a new zero-day attack in the wild, be sure to apply the Fix it or ensure EMET is protecting Internet Explorer for protection.

#TBT: Take a gander at this vintage job ad for Sophos... Circa October 1988, published in Daily Information for Oxford University.

FYI, this position has been filled. ;-) But we have other opportunities that I have opened up since: https://www.sophos.com/careers

Unlike Microsoft, at least Mozilla were able to release an update with their announced vulnerabilities. Get over to getfirefox.com or check for updates if you are a Firefox surfer.
 
For the second day in a row critical web browser flaws have been made public. This time it was Mozilla's turn releasing Firefox 24.0 fixing 17 vulnerabilities, 7 of which are critical.

Nice property, excellent views. Property is a little dated, but certainly still a great place to holiday.
