Chrome permits bad websites to send spam from one's email account???

(1/3) > >>

cyberdiva:
Hi, all.  I'm trying to get more information about something I've just been told about Google Chrome.  Yesterday, I received a spam message from someone I know.  I assumed that her email account had been hacked, and I wrote to her to let her know.  Today, I received a reply from her, saying that "Actually, there is some kind of security gap in Google Chrome that allows a bad website to send out spam from my account."  I'm highly skeptical of this explanation.  I'd imagine that 1) if there were so serious a flaw in Chrome, there would have been mention of it in lots of places that I read, and 2) Google would have quickly found a way to fix it.  I don't use Chrome, but if I did, I'd drop it like a hot potato if it had such a flaw.   Has anyone here heard of or experienced this flaw?

Just for the record, when you say "from", do you mean you checked the headers and it looked like it was a message genuinely sent from her account, or just that the "From:" field in the e-mail contained her e-mail address?

Good question, Jibz.  The message was such obvious spam that I didn't bother to check the headers.  I simply assumed that someone had hacked her MSN email account and was now sending spam to everyone in her addressbook.  I wrote to let her know, and in response I got the explanation I quoted in my original message here.  It didn't seem like a likely explanation, so I thought I'd post a message here and see whether anyone has heard of a similar "problem" with Chrome.  But now that you've asked, I looked at the headers.  There weren't a lot, especially before the message was received at my university (where I have the email account to which the message was sent).  Here are some key pieces of info from the headers (I've changed the name of the person I know to janedoe and my university's address to ********.edu):

The return path header was Return-Path: <[email protected]>

The headers from the start to when it got to my university were as follows:
Received: from snt0-omc4-s11.snt0.hotmail.com (snt0-omc4-s11.snt0.hotmail.com [65.55.90.214])
   by ********.edu (mx3.********.edu) with ESMTP id q5I2vdq7025380
   for <cyberdiva@********.edu>; Sun, 17 Jun 2012 22:57:41 -0400 (EDT)
Received: from SNT102-W47 ([65.55.90.201]) by snt0-omc4-s11.snt0.hotmail.com with Microsoft SMTPSVC(6.0.3790.4675);

X-Originating-IP: [189.224.78.19]
From: Jane Doe <[email protected]>

If the Originating IP # is not forged, it's in Mexico.  I don't know where this person lives (I "know" her only via listservs we're both on); I kinda doubt she's in Mexico, though it's not impossible.  The message-ID ends in @phx.gbl, which is apparently something that appears in many messages from Microsoft-related mail.  Since she's got an account at msn.com, I guess that makes sense.  Perhaps so too does the appearance of hotmail.com in one of the headers, I don't know.  All the unshown headers after these (leading up to the Return-Path header) look normal.  They're all internal to my university.

So no, it's not just the "From" field that makes me think it came from her account, but the Originating-IP in Mexico does give me pause.  I'm not sure, however, whether the headers indicate clearly whether her email account was simply hacked or whether somehow a "bad website" was able to send spam from her account (her explanation).  Any thoughts?

Thanks in advance.

I'd go with Hotmail hacked. It's happened to me, same kind of thing, everyone in my Hotmail contacts started receiving spam saying it was from me.

Yeah, the headers look fairly believable, and if there was some security hole that would allow this in any browser, I am sure it would be widely publicized.
