For the past couple of days I have been receiving emails from Yahoo! claiming they have stopped unauthorised access to my account.Someone attempted to sign in to your Yahoo! account from an app that doesn't meet Yahoo's security standards. We blocked this sign-in attempt, which was made on: Tue, 7 Jun 2016 21:39 BST from United Kingdom.My issue is that Yahoo! do not provide any information beyond that. The access block is confusing as I am using my devices at the time of the alleged block and none of them have complained about being not able to connect.My devices are:Windows 10 PC using FirefoxNexus 7 using the Yahoo! Mail appMoto G using the Yahoo! Mail appIs there any way to find out the IP address and/or user-agent string of the blocked access?
Understanding Yahoo! Security Warnings
security;yahoo mail
It appears that these warnings are being generated from my chat/IM client (Trillian) as Yahoo are in the process of relaunching Yahoo Instant Messenger. I only discovered this when I installed the Trillian app on my mobile. I got a security warning immediately when Trillian launched for the first time.
