Fun with Passphrases!, (Thu, Apr 24th)

As systems administrators and security folks, we’ve all had our fill of our users and customers using simple passwords.  Most operating systems these days now enforce some level of password complexity by default, with options to “beef up” the password requirements for passwords. The prevailing wisdom today is to use passphrases – demonstrated nicely by our bud at xkcd – http://xkcd.com/936/ So I routinely have very long pass phrases for public facing accounts.  Imagine my surprise when I was creating a new account on major cloud service (the one that starts with an “O” and ends with a “365″), and found that I was limited to a 16 character password.  Needless to say I have a case open to see if that limit can be removed.  I’m not looking for no limit / invitation to a buffer overflow status on the password field, but something bigger than 16 would really be appreciated !     (c) SANS Internet Storm Center

Be Careful what you Scan for!, (Thu, Apr 24th)

After some fun and games at one customer site in particular, I found that the SSL services on the earlier versions of the HP Proiliant Servers iLo ports (iL01 and iLO2) are not susceptible to heartbleed. However, their implementation of SSL is fragile enough that scanning them for the Heartbleed vulnerability will render them inoperable.  This affects Proliants from G1 all the way up to G6, as well as many of the HP Bladesystems.  A complete power down of the entire system – as in remove both of the AC cables – is required to reset the iLo card and bring it back to life.  While this may seem  like a quick fix for a single server, if that server is running a Hypervisor, or if it’s a bladesystem with Hypervisors running on the blades, this can multiply to be a huge issue.  Especially if your client scanned the server subnet, and effectively bricked all their iLO cards before they realized there was a problem (oops) (And yes, the fact that we worked this out Easter weekend is somewhat ironic.) Full details are in HP Support Document c04249852 This illustrates that even when scanning for simple things (with NMAP, Nessus or any other scanning tool really), it’s best to scan a few test systems first – or if you have a test VLAN that replicates your production systems, even better!   This isn’t a problem with the scanners, almost always the problem is the fragility of the service being scanned.  Many services are only written to deal with “the right” inputs, which is not how most scanners (or most attackers) tend to operate. Safe Scanning Everyone! ======================== Rob VandenBrink Metafore (c) SANS Internet Storm Center.

Finding the bleeders, (Mon, Apr 21st)

Now that the frantic frenzy around “Heartbleed” has calmed, and most sites are patched, it is time to circle back. For a server at a community college that I knew had been affected, I wanted to see if someone had pulled any data via Heartbleed during the roughly 36 hours between when the vulnerability became widely known, and when IDS signatures and patches were deployed to protect the site. Problem is, Heartbleed leaves basically no traces in the httpd server log, so checking there for attacks didn’t help

Testing your website for the heartbleed vulnerability with nmap, (Fri, Apr 18th)

We have received reports by many readers about buggy tools to test for the heartbleed vulnerability. Today I want to show you how easy it is to check for this vulnerability using a reliable tool as nmap. You just need to trigger a version scan ( -sV ) along with the script ( ssl-heartbleed ).
