How can this be? Have I been hacked into? I do have full<br \/>\ninternet security avg 9,could you please let me know what action to take if any<br \/>\nas I find this quite worrying! I have changed my password so far, but that is<br \/>\nall.<\/em><\/p>\n<p><strong>You should be worried.<\/strong><\/p>\n<p><strong>I&#8217;m not sure that I&#8217;d say you&#8217;ve been &#8220;hacked into&#8221;, but my guess is that<br \/>\nyour email account has indeed been compromised.<\/strong><\/p>\n<p>I&#8217;ll look at what likely happened, why this isn&#8217;t like other &#8220;Someone&#8217;s<br \/>\nsending from my email address!&#8221; kind of issues, and what  steps you need to take<br \/>\nnext.<\/p>\n<p>The big clue here is that email is being sent from you to <strong>contacts<br \/>\nin your address book<\/strong>.<\/p>\n<div class=\"pullQuote\">&#8220;Most email programs now carefully protect against<br \/>\nunauthorized address book access.&#8221;<\/div>\n<p>In the &#8220;old days&#8221;, that typically meant that your computer had acquired a<br \/>\nvirus, and that virus was in turn accessing your PC&#8217;s email program and<br \/>\nsystematically sending email to everyone in your contact list or address<br \/>\nbook.<\/p>\n<p>While that&#8217;s still a possibility &#8211; and you should absolutely make sure that<br \/>\nyour anti-malware tools are running and up to date &#8211; it&#8217;s not nearly as common<br \/>\nas it once was. Most email programs now carefully protect against unauthorized<br \/>\naddress book access.<\/p>\n<p>What more likely occurred is that your email account has been compromised<br \/>\n &#8211; meaning that you probably have an on-line email account, free or otherwise, that<br \/>\nsomeone has gained access too. By virtue of doing so they now have access not only<br \/>\nto your email, but to your address book as well. It&#8217;s all too common these days to hear<br \/>\nof folks whose accounts have been compromised only to have all their friends<br \/>\nget inundated with spam, threats, malicious emails or messages that try to<br \/>\nimpersonate you and scam your contacts out of money.<\/p>\n<p>How this happened is difficult to say. It could be anything from a weak<br \/>\npassword that&#8217;s easy to guess, to your account credentials being sniffed in an<br \/>\nopen WiFi hotspot, to your simply having shared the account information with<br \/>\nsomeone you should not have.<\/p>\n<p>For all we know, it could also be a roommate walking up to your computer<br \/>\nwhen you&#8217;re not using it and sending messages right then and there.<\/p>\n<p>(And for the record, last year there was a partial account compromise at one<br \/>\nof the larger free email services &#8211; account credentials were stolen without the<br \/>\nusers having done anything wrong. Same result.)<\/p>\n<p>I&#8217;ve talked before about email that appears to come from you, but in fact<br \/>\ndoes not. This is different. Specifically:<\/p>\n<li>\n<p>Spam email is sent to random people you don&#8217;t know, &#8220;spoofing&#8221; the From:<br \/>\naddress to make it look like it comes from you when it does not. There is<br \/>\nalmost nothing that can be done about this.<\/p>\n<\/li>\n<li>\n<p>Email from stolen accounts is sent to people <em>in your address book<\/em>,<br \/>\nand is not spoofed at all &#8211; it really is coming from your account. It&#8217;s just<br \/>\nnot you sending it.<\/p>\n<\/li>\n<\/ul>\n<p><a href=\"http:\/\/ask-leo.com\/is_changing_my_password_enough.html\" target=\"_blank\">Is Changing Your Password Enough?<a><\/p>\n<p><\/p>\n<p>[This post is excerpted with Leo&#8217;s permission from his <a href=\"http:\/\/ask-leo.com\/\" target=\"_blank\">Ask Leo<\/a> blog.]<\/p>\n<p><i>Leo Notenboom has been involved in the tech industry for nearly 30 years.
