Hello,

 

I am new to the forum and I hope it is appropriate to begin with a request for help. 

I am running windows 7 Professional on an x64 system. I have not noticed anything unusual in my computer's performance - no popups, redirects, unusual slowness or crashing. 

 

A friend reported getting an email from my account, with my name in the subject line and a strange link as the only content. I had not sent it. I could see from the recipients list that it was also sent to a few other people in my contacts list, who would otherwise not know one another. I checked with another contact and she received a similar email with a different link included, and some different contacts in the recipient list.

 

I examined the header from one of these emails and saw it had a strange address in the Return-Path field. There were other details in the header that appeared odd to me, although I am not really competent to assess that.

 

There is no record of any of these emails in my sent folder. Nor did I receive any bounced emails, which i attribute to the alternate address in Return-Path. 

 

I have run Malwarebytes antimalware, which found no suspicious items, Super antispyware, which found only a bunch of tracking cookies, and a Sophos antivirus scan, which found no suspicious items.

 

I am particularly concerned about the fact that these emails seemed to have access to my address book. Is this a likely indicator of some kind of malware on my system and how should I proceed.

 

Any help is very much appreciated,

Bryan

From what you describe, it appears your email account has been hacked or spoofed (email address forged as the sender). You need to reset your Microsoft account password if using Hotmail/Outlook. I suggest you create a strong password. Sometimes just doing that will resolve the issue.

* Help! My Email was Hacked! (Outlook/Hotmail)

Please note that Microsoft also has a new private secure online form to report various Microsoft account issues. See Microsoft Account Support. At the bottom of this support page is a note that says "If you can't sign in with your Microsoft account, create a temporary account at https://signup.live.com.

Hi,

 

Thanks for your help. I did the things recommended in those articles. 

 

I wonder how it is that someone could have gotten my address book? Is it likely that I have malware or is it possible that the address book was somehow stolen from me in some other way? I guess I want to know how worried I should be about my computer being compromised. 

 

I have seen the headers from a few of these emails. They are not coming from my account. Hotmail also allows you to check the recent history of access to an account and there are no suspicious logins to my account. I can see from the email headers that different accounts are being used to send these emails, with my account spoofed in the "from" and "reply" fields and with the recipients all pulled from my address book. 

 

Also, I can't think of any way to stop these emails, since they don't seem to be originating from my account. 

 

Bryan

If you want a more detailed look at your system, then more advanced tools are needed to investigate as Many of the scanning we use in this forum are not capable of detecting (repairing/removing) all malware variants. Before that can be done you will need to create and post a DDS log for further investigation.

Please follow the instructions in the Malware Removal and Log Section Preparation Guide starting at Step 6.
  • If you cannot complete a step, then skip it and continue with the next.
  • In Step 6 there are instructions for downloading and running DDS which will create two logs. (Note: Windows 8.1 Users will not be able run DDS and create a log)
When you have done that, post your logs in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team.

Start a new topic, give it a relevant title and post your log(s) along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. If you cannot produce any of the required logs, then still start the new topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happened when you tried to create them. A member of the Malware Removal Team will walk you through, step by step, on how to clean your computer.

After doing this, please reply back in this thread with a link to the new topic so we can closed this one.

You're welcome.

Now that your log is posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Response Team member...nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show in the log(s) you already posted. Further, any modifications you make on your own may cause confusion for the member assisting you and could complicate the malware removal process or make things worst which would extend the time it takes to clean your computer.

From this point on the Malware Response Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take several days to get a response because the Malware Response Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have posted your log and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the Malware Response Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another Malware Response Team member is already assisting you and not open the thread to respond.

If HelpBot replies to your topic, please follow Step One and CLICK the link so it will report your topic to the team members.

To avoid confusion, I am closing this topic.

Good luck with your log.
