I keep getting email form Google telling me my account has been hacked:

[i]Hi MY NAME,

We recently blocked a sign-in attempt to your Google Account [MY EMAIL@googlemail.com].

Sign in attempt details
Date & Time: Sunday, March 1, 12:00 PM GMT
Location: United Kingdom

If this wasn't you
Please review your Account Activity page at https://security.google.com/settings/security/acti... to see if anything looks suspicious. Whoever tried to sign in to your account knows your password; we recommend that you change it right away.

If this was you
You can switch to an app made by Google such as Gmail to access your account (recommended) or change your settings at https://www.google.com/settings/security/lesssecur... so that your account is no longer protected by modern security standards.

To learn more, see https://support.google.com/accounts/answer/6010255...

Sincerely,
The Google Accounts team[/i]

I've changed my password four times now, the last time to a 10-character random number and letter string, but it is still getting compromised.

Any ideas what is going on?

If you haven't already, turn on 2 step verification:

Is it actually from Google?

The access is being blocked every time according to Google, so it's not been compromised?

It could be something as simple as someone trying to log into their account which is something similar to yours. I have a regular email coming round from family that I dont have, the intended recipient has the same address as me, just without the dot between our first and second names.

On the other hand, it could be a specific attack at your account (amongst millions of others) based on your email address. It's still not been compromised? What Google are saying is change the password to be a complicated one that isnt in a dictionary to make it harder and harder to guess, not that you just need to change your password from password to mypassword

^ Very much this

Also, check that the links direct you to actual Google pages (if you hover over the link, it should pop up the actual address you'll be taken to which can be different from what's displayed in the message).
I never click on links within these sorts of emails, better to go search for the page yourself so you know you're not being directed to a copy designed to harvest your login details.

No it isn't. The email from Google tells you that they BLOCKED the attempt. Someone is trying to sign on as you and failing.

However, the advice given above about 2-factor auth. and more complex passwords is valid and should be followed to reduce the chances of the attempted sign-ons becoming successful.

Has anyone actually read the OP?

The claim is that someone is continually attempting to access his GMail using the correct password, despite it being changed.

This seems unlikely to me, but if it is the case, then you need to look at the root cause: i.e. you have a keylogger or other means of security compromise on your machine, or less alarmingly, that you are triggering these security warnings yourself.

If they were using the correct password why would Google block it?

Because, like when your bank rings you to query a transaction, it either correlates with a known attack pattern or doesn't fit the expected usage pattern.

So maybe for example: signing in from a random Russian IP whilst the phone is still in the UK, or using a strange browser signature, or the same IP is trying to automatically log in to loads of accounts at once, or whatever.

Ooops. Missed that.

OP - do you have any new devices or have any devices changed networks recently (e.g. mobile phones, tablets, laptops) ? ISP using dynamic IP allocation and migrated you to a different block ?

That can trigger the Google system to throw a warning about unknown logins from unexpected locations until you authorise them.

Didn't realise that. Nice to hear.

As above. The answer is 2-Step authentication and a few different AV scans of your PC - Malwarebytes etc

I get the same emails. In fact I got one this morning. For me it ties in with whenever I have restarted my Mac. It only happens rarely and pretty much always soon after I have rebooted it.

OP is there anything like that that ties in with you getting the emails?

Since the trigger originates in the UK during UK daytime, I reckon the probability is high that the OP is activating the alerts himself, although I don't know why he wouldn't notice the failure to sign in.

Maybe a phone trying to sync, or some software like a messenger app that integrates into GMail but doesn't produce a highly visible failure - or alternatively, malware attempting to log in from his own PC, but that seems unlikely.

You going around with your mobile phone attempting to pull from gmail?

If you load up gmail, then click in the bottom right the word 'details' it will list all the attempts.

See if there are lots of ATOM feeds/IMAP etc attempts.. do a copy paste here if you like.

gmail addresses also ignore anything after a + sign which can be very handy for filtering. i.e. sign up to mailing lists using myname+stuff@gmail.com and it'll still get delivered to myname@gmail.com but you can send them all to another folder/spam/whereever. If you use a different code for each sign-up you can also see who has sold your details.

I get these every now and then since blocking access to less secure apps in the Account settings. I figured that's how I'd leave it unless I find something doesn't work that I want to. Check your account settings OP under the signing in section for Access to less secure apps and see if it's set to Block.

I did it after getting the check your account security settings to get 2Gb free on Drive.

I've been using free zenmate vpn which has five locations, one in the UK, then US DE,CH,HK and I've had the Google change password thingy as they think I'm signing in from a different country when signing in to gmail, guess their pattern matching says can't be in all locations in such a short space of time, sent him a 'passwordy' email.
