British Intelligence, GCHQ, Oxford & Debian conspiracy theories, Edward & Una Brocklesby fact checking
Reprinted with permission from Daniel Pocock.
At 21:00 UTC on 5 June 2024, I published the first disclosure about the secret expulsion of Edward Brocklesby from Debian.
A few hours later and some of the rogue elements at Debian started spreading more defamation about me. It looks like the disclosure about Debian's lack of competence for security has struck a chord and people need to look more deeply at this particular case.
As the elections are in progress the Internet is full of conspiracy theories right now. An Irish election candidate poking fun at British Intelligence should be viewed with scepticism and fact checked very carefully.
Therefore, I will simply link to some of the facts and leave it up to the community to draw conclusions.
The first thing to note is that GCHQ is reknowned for their use of puzzles. For example, they have published puzzles as a strategy for recruiting people. The stuff about GCHQ using puzzles is widely known and published by GCHQ themselves and it is also described by the press in the UK and abroad. From RTE, Ireland's national broadcaster:
An Irish code-breaker, along with two others, has proved he is almost a match for the UK's national intelligence and security agency by winning its Christmas card cryptography challenge.
One of the first things that people found about Edward Brocklesby is a web page about Chess scores from the Oxford Cambridge Varsity competition in London. The games took place in 1935 and 1936. The page tells us that this particular Edward Brocklesby was born 29 April 1914 and died 9 December 2004. Clicking through the pages we find a link to another article telling us this was Edward Willingham Brocklesby who was originally associated with Cambridge but later went to Oxford. However, the middle initial doesn't match Edward J Brocklesby in Debian.
In practice, we know that people are not always using their real names in Debian and free software. People may tweak their initials or use pseudonyms. For example, the woman using the name "cryptie" in the FSFE subsequently had to reveal she was a French Government employee moving to a job at the European Union. She admitted her real name is Amandine Jambert and her conflict of interest and resigned.
It is not uncommon for people to commit identity fraud by using the names of other real people, whether alive or dead, rather than making up names that are entirely fictitious. Using the name of somebody who is elderly or somebody with a disability is a special case.
The name of the FSFE is itself an example of identity fraud because it is confusingly similar to the real FSF. This type of thing is very common in open source software.
People found a HP Enterprise Forum account for Edward Brocklesby. The account was created 12 May 2003 and last used on 21 June 2011. It is not uncommon for accounts in online forums to be hacked so even if the account was created by the "real" Edward Brocklesby from Debian, it may have been used by another person in later years.
The 192.com directory service finds both Edward Brocklesby and Una Brocklesby living at the same address that is used in the document submitted to the IETF. 192.com tells us they are on the electoral roll at that address at the same time and both of them were removed from the electoral roll in 2002, not long after the Debian expulsion.
There are various reasons somebody could be removed from the electoral roll. They might die, they might move to another country or they might have simply moved to another address and decided not to enroll again. However, there are also special cases for police and military employees to have their status on the electoral roll protected.
There are many regular police units who have engaged in undercover activities. It would be wrong to assume every person using a fake name in Debian is with GCHQ or the NSA. London's Met Police issues with the undercover officer Mark Kennedy have been widely documented. It wouldn't be a big surprise to find people like this operating in free software communities.
There is an Una Brocklesby account on Trustpilot and she is in the UK and active between 2017 and 2024.
In the St Hugh's College, Oxford Chronicle of 1998-1999, we find that Una Brocklesby is listed in the staff section as a Finance Assistant.
This adds weight to the idea that they were either using their real names or they were very sophisticated deep cover agents, living as a couple, having paperwork and jobs.
Looking at Edward Brocklesby's activities in the debian-private cubby house over the years, we find most of his messages concern security topics. He appears to have various email addresses on different networks.

Hi,
A user on #shells was offering to trade www.tr.debian.org. It might be an idea to check security on this host.

and in this second example, Brocklesby signs off with Diolch, which is Welsh.

I filed a bug on this. In the end, we decided it was not a pine bug, but in fact some other program was inserting the bad stuff.
(Bug#33099, BTW)
Diolch, Edward.
The bug report gives us another email address and permutation of the name: █
