just for rob

Shortly after the launch of the new iPhone 5S, my old friend Rob emailed me trying to goad me into writing a post about it. After all, it was made by one of my least favourite companies and it contained a supposedly funky bit of kit in the shape of its fingerprint scanner. Rob pointed …

that’s another password I have to change

Michael Horowitz has posted an interesting article over at Computer world. In it he points out that, by default, most android devices (tablets and ‘phones) routinely ‘phone home to Google to back up Wi-Fi passwords along with other assorted settings. Google sells this option as a convenience to help you regain settings after you upgrade …

RSA says don’t use RSA

A report in wired today says that RSA Security [*] have released an advisory to developer customers noting that the Dual Elliptic Curve Deterministic Random Bit Generation (or Dual EC DRBG) algorithm (the one which is subject to speculation about NSA interference) is the default in one of its toolkits and strongly advised them to …

add ssl to lighttpd server

For some time now I have protected all my own connections to trivia with an SSL connection. I do this to protect my user credentials when managing trivia’s content or configuration. In fact my server is configured to force any connection coming from my IP address to a secured SSL connection so that I cannot …

openPGP usage

Over at the the cypherpunks mail list, one Tony Arcieri posted a graphic showing an interesting rise in the number of OpenPGP keys registered on the SKS keyserver in the last month or so. The graphic comes from the SKS statistics page. The overall trend is clearly upwards, and has been for some time, but …

untrusted dod certificate

Chris Williams over at El Reg posted a nice article about the kind of crypto best practice you need to follow if you care about privacy. The article questions the wisdom of using David Miranda as what Williams calls a “data mule” to carry physical electronic media (possibly) containing sensitive data through Heathrow and goes …

tor usage on the rise

A couple of weeks ago I noted that the release of tails 0.20 seemed to be popular – at least if the traffic on my mirrors was anything to go by. The statistics published by the Tor project itself show an interesting rise in (probable) Tor usage since June. The graphic shows that the number …

aunty doesn’t get it

The BBC has today commented on the Guardian story about David Miranda’s detention for nearly nine hours at Heathrow under Schedule 7 of the UK Terrorism Act 2000. The BBC’s on-line report ends with a web feedback form asking: Have you been detained under schedule 7 of the Terrorism Act 2000 at a British airport, …

tor users under attack

The Tor network does not just provide anonymous internet access, it also provides for so-called hidden services. These services are not visible outside the Tor network and are only reachable over Tor. The servers are given Tor specific addresses of the form “xyz123.onion” (actually, the addresses are a little more complicated than that because the …

lavabit dead

I run my own mail server for a number of reasons. And I rarely regret that decision. However, there have been occasions in the past when relying on a single mail provider (even when that provider is myself) has proven problematic. The first problem arose several years ago when the ISP which I use for …

security failure at digital ocean

This morning I received an email from Digital Ocean titled “Avoid Duplicate SSH Host Keys”. The email said: “If you have created an Ubuntu Droplet or snapshot prior to July 2nd, DigitalOcean recommends regenerating the SSH host keys. Droplets based on standard images now create unique SSH host keys.” (This, of course, implies that they …

repeat after me – snowden is not the story

John Naughton has an interesting column in his “networker” series in today’s Observer. In it he laments the fact that the majority of the world’s mainstream media seem more intent on reporting on Snowden the man than on what Snowden has revealed. He starts: “Repeat after me: Edward Snowden is not the story. The story …

soldier available cross magnet

I am in the process of changing passwords on a bunch of different systems/applications and have been pondering my algorithms, so to speak. Like my friend David, I have an internal model of varying password schemes which I can use in different places. This means that I can happily pick a password for a low …

Right now (21.00 today), the ubuntu forums site says it is “down for maintenance”. It appears to have been down since yesterday. The site reports: There has been a security breach on the Ubuntu Forums. The Canonical IS team is working hard as we speak to restore normal operations. This page will be updated regularly …

save your money – just use tails

I suppose it was inevitable that the Snowden revelations would lead to greater interest in privacy and anonymity. I applaud that. I suppose it was also inevitable that there would be a rash of commercial products emerging from both “entrepreneurs” and the more established “security” companies to take advantage of that increased interest. That, I …
