Mail Hijacked?

[mrnotu]

HiYa, I opened my mail today and found 32 failure notices of mail that could not be delivered. I sent no mail. Some of the adresses are in my contacts and some are not. Has my account been hacked? This is a sample of the emails. All are about the same. I have changed my password anything else?

If your using gmail, when you logged on did gmail report any suspicious activity in your account recently.
Yahoo mail will give out a warning if it spots a different ip address other than yours.

I had a nice long stare at your screen shot, its obvious that its a scammer/hacker is trying to get access in your email accounts.
Best thing you can do for now, make a secure password you remember and move any emails that you dont recognize to spam and flush it out the debris every week.
File a complaint with your email servicer and show them what you have currently.
Check your inbox as I have something I want you to look at personally.

Change your password on a computer that is not one you usually use.

Scan your current computer with MalwareBytes Antimalware and HiJackThis and post the logs.

Thanks for the replys. I am using Yahoo.mail and have had no warnings about my account. I clean out spam daily or try too. Do you think this may be someone that I know? I did log into my account on a friends computer two days before to check things but I did log out and I told it not to remember my password. Maybe his computer is compromised and I opened the door when I used it. I am currently running MalwareBytes and will see what it says. I have 3 more of these failure notices today. I wonder if this is just random hits on me or if I am going to be targeted. I do not like this crap. Thanks

Have you replied to any suspicious emails recently? Or logged into a 2rd party website with the account? Change pass, security questions, etc. and use the security key

No I do not open any mail that I do not recognise or know, they go right out with the spam.

I have not been hit for a while so I guess it is out of my system. Did the scans and deleted a few things. Hopefully it is gone. I do think somehow me logging into my mail from my brother-in-laws computer is how I was attacked.

He was possibly infected?

Do not know. I am not that smart about computers. But my inlaw did say he was having trouble with his and it happened right after. Just a 1 + 1 guess is all. Any ideas? And I am not saying mine was infected I am saying his was and got my info from his.

Either:
1. You were infected (probably solved now)
2. You logged in with your account to a phishing site
3. He was infected
4. He logged into a phishing site
5. The FBI is messing with you. (Im kidding.)
