CVE-2014-6271 bash vulnerability

Guess what I found in trivia’s logs this morning? 89.207.135.125 – – [25/Sep/2014:10:48:13 +0100] “GET /cgi-sys/defaultwebpage.cgi HTTP/1.0” 404 345 “-” “() { :;}; /bin/ping -c 1 198.101.206.138” I’ll bet a lot of cgi scripts are being poked at the moment. Check your logs guys. A simple grep “:;}” access.log will tell you all you need …

net neutrality

My apologies that this is a few weeks late – but it still bears posting. John Oliver at HBO gave the best description of the net neutrality argument I have seen so far. Following that broadcast, the FCC servers were, rather predictably, overwhelmed by the outraged response from the trolls that Oliver set loose. Unfortunately, …

levison on dime

Ladar Levison and Stephen Wyatt presented the upcoming Dark Internet Mail Environment (DIME) at Defcon22 this week. According to El Reg, Levison, who shut down Lavabit, his previous mail service rather than comply with FBI demands that he divulge the private SSL certificates used to encrypt traffic on that service, said: “I’m not upset that …

punctuation matters

There is a nice tweet over at @NSA_PR. It reads: We take your privacy, seriously. Beyond parody.

department of dirty

Like most ‘net users I get my fair share of spam. Most of it gets binned automatically by my email system, but of course some still gets through so I am used to hitting the delete button on random email from .ru domains offering me the opportunity to “impress my girl tonight”. Most such phishing …

drip

I get my domestic ADSL connectivity from the rather excellent people at Andrews and Arnold. Here’s why. And this is the original reason I moved to them. They also happily take (and similarly reply to) GPG encrypted support questions. Good guys. Thoroughly recommended. Now can you /really/ see BT doing any of that? ‘thought not.

inappropriate use of technology

I have been travelling a lot over the last few months (Czech Republic, Scotland, France, Germany, Austria, Slovenia, Croatia, Italy). That travel, plus my catching up on a load of reading is my excuse for the woeful lack of posts to trivia of late. But hey, sometimes life gets in the way of blogging – …

a new app

My newspaper of choice, the Guardian, has for some time produced its own android (and iOS of course) app. I have often used the android app on my tablet to catch up on emerging news items at the end of the day. I also read the BBC news app for the same reason. Yesterday I …

nsa operation orchestra

In February of this year, Poul-Henning Kamp (a.k.a “PHK”) gave what now looks to be a peculiarly prescient presentation as the closing keynote to 2014’s FOSDEM. In the presentation (PDF), PHK posits an NSA operation called ORCHESTRA which is designed to undermine internet security through a series of “disinformation” or “misinformation”, or “misdirection” sub operations. …

more heartbleed

For any readers uncertain of exactly how the heartbleed vulberability in openssl might be exploitable, Sean Cassidy over at existential type has a good explanation. And if you find that difficult to follow, Randall Munroe over at xkcd covers it quite nicely. My thanks, and appreciation as always, to a great artist. Of course, Randall …

pulitzer guardian

The Guardian and the Washington Post have been jointly awarded the Pulitzer prize for public service for their reporting of Edward Snowden’s whistleblowing on the NSA’s surveillance activities. The Guardian reports: The Pulitzer committee praised the Guardian for its “revelation of widespread secret surveillance by the National Security Agency, helping through aggressive reporting to spark …

boot and nuke no more

I was contacted recently by a guy called Andy Beverley who wrote: Hope you don’t mind me contacting you about one of your old blog posts “what gives with dban”. Thought I’d let you know that I forked DBAN a while ago, and produced a standalone program (called nwipe) that will run on any Linux …

heartbleed

This is nasty. There is a remotely exploitable bug in openssl which leads to the leak of memory contents from the server to the client and from the client to the server. In practice this means that an attacker can read 64K chunks of memory on a vulnerable service, thus potentially exposing security critical information. …

the netbook is not dead

I bought my first netbook, the Acer Aspire One, back in April 2009 – five years ago. That machine is still going strong and has seen umpteen different distros in its time. It currently runs Mint 16, and very happily too. The little Acer has nothing on it that I value over much, all my …

the spy in your bathroom

Back in June 2008 I noted Craig Wright had posted to bugtraq reporting a “remote exploitation of an information disclosure vulnerability in Oral B’s SmartGuide management system”. I found it faintly amusing that a security researcher should have been looking for vulnerabities in a toothbrush. I should have known better. A report in wednesday’s on-line …

checking client-side ssl/tls

At the tail end of last year I mentioned a couple of tools I had used in my testing of SSL/TLS certificates used for trivia itself and my mail server. However, that post concentrated on the server side certificates and ignored the security, or otherwise, offered by the browser’s configuration. It is important to know …
