Does anyone know of any research measuring whether users have trouble copying urls from an sms on iPhones?How many people would accidentally click on a (potentially malicious) link instead of copying it?

Does anyone know of any study showing that randomly clicking on random ads really confuses online trackers?

We changed the date of WEIS to June 21-22; we were unaware that June 20 is the Juneteenth holiday in the USA. Sorry about that. Anyway, we hope to see lots of you there -- and now there's an added holiday!
The 2022 Workshop on the Economics of Information Security will be held in person if possible – in Tulsa, Oklahoma, on June 20 and 21. Papers are due by the end of February: lightbluetouchpaper.org/2021…

IP blocklists are a simple defence available to network operators, but problems can occur when identifying malicious entities based solely on IP addresses. #netsec #netops blog.apnic.net/2020/12/22/re…

Excited for Sivaram's (@Sivaram65352465) talk at #IMC2020 on measuring the unintended blocking by blocklists! Use our code and data to stop excessive blocking: (data) steel.isi.edu/projects/BLAG/, (code) github.com/sivaramakrishnans…
I will be presenting our work on Quantifying the impact of Blocklisting in the age of address reuse at #IMC2020 tomorrow! Joint work with Anushah Hossain, Jelena Mirkovic, Minlan Yu (@minlanyu) and Sadia Afroz(@sheetal57) Find our video here youtu.be/oPMqNHiHey4 (1/11)

A week ago, Facebook sent me a C&D asking us to take down AdObserver and delete our data. The public has a right to know how political ads are targeted, so we will not be complying with this request. Please consider installing Https://AdObserver.org

Suppose you are a Cloudflare user behind a NAT and find your IP address blocked because of ONE spammer you are sharing your IP address with. This actually happens: community.cloudflare.com/t/c… but how often? We measured such unintended blocking in our upcoming paper at @imc2020! (1/4)

(3/4) We started looking into server-side blocking realizing that Tor is blocked more by well-meaning websites than by repressive regimes for “security”. Later found that many western websites also block access from African countries for similar reasons: usenix.org/conference/enigma…

(4/4) NATs and dynamic allocation are the reality in many countries. IP address blocklists not caring about address reuse will continue to block innocent users. How can companies avoid such unintended blocking? We provide a way to easily find reused addresses. Coming up soon!
