tor and the UK data communications bill

As a Tor node operator, I have an interest in how the draft UK Data Communications Bill would affect me should it be passed into law. In particular, I would be worried if Tor ended up being treated as a “telecommunications operator” within the terms of the Act (should it become an Act). Fortunately, Steven …

a positive response

Whenever my logs show evidence of unwanted behaviour I check what has happened and, if I decide there is obviously hostile activity coming from a particular address I will usually bang off an email to the abuse contact for the netblock in question. Most times I never hear a thing back though I occasionally get …

iptables firewall for servers

I paid for a new VPS to run tor this week. It is cheaper, and offers a higher bandwidth allowance than my existing tor server so I may yet close that one down – particularly as I recently had trouble with the exit policy on my existing server. In setting up the new server, the …

tails has not been hacked

I run a tails mirror on one of my VMs. Earlier this week there was a flurry of anxious comment on the tails forum suggesting that the service had been “hacked”. Evidence pleaded in support of that theory included the facts that file timestamps on some of the tails files varied across mirrors, one of …

fail

My new bank (which is actually one of the few remaining mutuals in the UK) sent me my voting forms for the AGM today (by postal mail). The information pack included details of how to vote on-line should I choose to do so, together with two unique “voting codes” one of eight digits the other …

Michal Zalewski (aka lcamtuf) has just announced that google is changing the terms of its vulnerability purchase program. The google announcement says: Today, to celebrate the success of [the program] and to underscore our commitment to security, we are rolling out updated rules for our program — including new reward amounts for critical bugs: $20,000 …

now switch it back on

Bugtraq can be an interesting list. Back in June 2008 I noted that one Craig Wright had posted an advisory about a vulnerability in an Oral B toothbrush. Well, just over a week ago a chap called Gabriel Menezes Nunes posted a proof of concept remote denial of service attack on a Sony Bravia television …

banking stupidity

When I logged on to my new bank site this morning, I tried the “help” offered on the opening screen just to see what they had to say about the range of options available. I was not best pleased to be greeted by the message “Flash is not installed, is not enabled or is not …

moxie’s proxy

image of googlesharing proxy

Moxie Marlinspike, a security researcher probably best known for his SSL proxy tool, likes google even less than I do. His googlesharing website says: “Google thrives where privacy does not. If you’re like most internet users, Google knows more about you than you might be comfortable with. Whether you were logged in to a Google …

t-mobile resets its policy?

As I have mentioned in other posts here, I run my own mail server on one of my VMs. I do this for a variety of reasons, but the main one is that I like to control my own network destiny. Back in October last year I noticed an interesting change in my mail experience …

tunnelling X over ssh

OK, yes, I know there are probably already a gazillion web pages on the ‘net explaining exactly how to do this, but I got caught out by a silly gotcha when I tried to do this a couple of days ago, so I thought I’d post a note. Firstly, X is not exactly a secure …

tp-link respond

A couple of weeks ago, I wrote about the problems I had with a TP-Link IP camera. Today I received a comment on that post from a guy called Luke in the TP-Link support team. In that response he apologises for the difficulties I had and promises to investigate further. His response deserves as wide …

do not buy one of these

image of TP-Link IP camera

  Standalone IP cameras have come down in price quite remarkably over the past few years. It is now perfectly possible to get a camera for between £50.00 and £75.00, and this makes them attractive for anyone wanting to set up simple “home surveillance” systems. I bought one recently just to see what I could …

do I trust this site?

Following a visit to EFF to read an article on e-book privacy, I met this: So. EFF uses a wildcard SSL cert issued by a company which was breached earlier this year.

who are you going to call

Like most email users I get my fair share of spam and other internet crud. Mostly I ignore it, but I received an intriguing email a couple of days ago which purported to be a mailer daemon “Delivery Status Notification” informing me of a failed delivery to some address I had not even heard of. …
