Oh God. The app which has compromised all the phone numbers and emails of the Conservative Party is the notorious UCampaign app! Allied to #CambridgeAnalytica. I'll try to grab some info in the thread below
Here's a thread with some background on Thomas Peters who devised it.
This app is also one of the many bits of evidence that the same (probably hacked Facebook) analytics were used in the Leave Campaigns and for Trump @carolecadwalla @VickerySec @profcarroll businessinsider.com/donald-trumps-… 
Peters writes extensively about his #Brexit app on Medium. Worth reading how it worked. medium.com/@uCampaignCEO/…
This wasn't ANY old data uCampaign were using for their app targeting. It was the data hacked from million of Facebook users which #CambridgeAnalytica based their psychometric profiling and targeting on
But here's BREAKING thing. The uCampaign App, developed by a Ukrainian military veteran, funded by US billionaire close to #CambridgeAnalytica, specifically named in @DamianCollins DCMS with 'major privacy concerns'. And yet the Tory Party still used it publications.parliament.uk/pa/cm201719/cm…
According to Techcrunch the Conservatives were still using the Campaign (not conference) App despite all the DCMS warnings about data privacy and #CambridgAnalytica connections techcrunch.com/2018/07/30/one…
Thanks to @brexit_sham for podcast from the uCampaign app developer, Thomas Peters, we have DIRECT EVIDENCE #CambridgeAnalytica data was 1) Used by Vote Leave 2) Used by Trump and 3) Now deployed by the Conservative Party
Oh. And if you're following this thread and missed the correction, apparently the Conference App (with current data breach) is different from the Campaign App (which seems to have many more potential breaches and be based on data from the massive Facebook hack)
More on the uCampaign App: it's only a YEAR old. And was recommended by the editor of @ConHome who
This app, with all its security flaws and lack of GDPR compliance was recommended to Conservative Activists. There was an incentive....
A year before launch: Theresa May wants to deploy an army of computerised ‘mind-readers’ to help her win the next Election. Tory chiefs have been in talks with Cambridge Analytica... credited with playing a key role in Donald Trump’s presidential victory.' dailymail.co.uk/news/article-4…
BREAKING: Though I confused the Campaign and Conference App stop of the thread, it seems there is still a common procurer: Anthony Hind. And he and the Conservative Party were warned in June techcrunch.com/2018/07/30/one…
WARNING: If Conservative Conference App users are worried about breach of phone numbers and emails, ANY FRIEND OF ANYONE using the Conservative Campaign App should worry: there's nothing in the legal agreement to stop your data being harvested nbcnews.com/politics/2016-…
This is what that data harvesting can mean (from the Cruz Campaign version). How do we know this isn't happening to Conservative Party activists and ALL their contacts? npr.org/2015/11/09/455…
Looks like little has changed in the Conservative Version of the Vote Leave/Trump/Cruz app. It still is asking for lots of detail on a profile and permission to access all contacts
Still no clue how many users of the Campaign App - but the Vote Leave version had 30k downloads and was on offer for a much shorter time. This has been active for a year.
To be clear the points system of 10k to 50k seems to be based on rewards for activity and sharing, and not directly to actual members.
