  • The attachment you are about to open may contain a virus. To continue opening, type "virus threat accepted", otherwise press return.

    On a very similar idea you could also have a form where there was the explanation, in which was said at the end to type "yes" or "no" into a text box and click okay. Perhaps something short but unique could be used for each different box. I think "virus threat accepted" is a little long, users might make a typo and not figure it out.

    E.G.
    You are about to format your disk. Formating your disk will erase all the information on it. Type "format" into the text box and click okay to format. Type "no" or click cancel to stop this operation. Remember, this formatting the disk will erase all information on it.

  • I wonder what hotmail does if you check the "remember my password" option..

    It probably just sends you the same cookie but with an expires field, so the browser will store the cookie on the hard drive. If the cookie doesn't have an expires field, then it's kept only memory. If you need to login as a new user, restart the browser.

    Of course, if one is going to do something like this over the Internet, it should be encrypted. BTW, slashdot isn't the only one. Linuxtoday.com uses plaintext cookies for authentication also.

  • I don't use Hotmail. Does it automatically display HTML attachments?

    Using an HTML file to execute malicious javascript seems pretty straightforward. Are any of the other web-based email services (Yahoo, Eudoramail, Mac.com, etc) vulnerable to similar attacks?

  • If your mental age stayed in the single digits, I suppose it could approach a low number, since you IQ is your mental age divided by your physical age.
  • Try logging on to Hotmail, not touching anything for 30 mins and then clicking on 'read mail'. If they have the server set up sensibly, you'll have to enter your user name and password again.

    On the other hand, if Microsoft have done something really really dumb, like including the password in a cookie, then there's really no hoe for them.

    Hotmail stores your user information in a session cookie, not a persistent (disk) cookie. If you close all your browser windows and access hotmail again, you are required to enter your password again... unlike Slashdot I might note.

    I know the session cookie has an expiration period, but I don't remember what it is. Probably something like 20 minutes.

I'm sort of irritated, though, that if I don't tell them stuff like this, they aren't going to learn it anywhere else.

  • It seems to me that it would be fairly trivial to embed an ActiveX component in an HTML email, to mess with people who read their mail with ActiveX-enabled software (Hotmail via MSIE, Outlook, etc.). Since ActiveX is just plain-vanilla binary executables with the most minimal security imaginable, it could do all sorts of unpleasant things when viewed. It could, for example: propagate itself (by interfacing with Outlook), embed itself into every HTML file on the user's hard drive, embed itself into all outgoing HTML mail (in which case it could become nearly uncatchable), send all sorts of info over the net, install backdoors, etc. I'm surprised it hasn't been done already.

I have yet to meet the person that can not qucikly think of at least 5 times they did things that any rational person would comment as completely stupid.

  • I think he was about to say "with very small cranial cavities", but I could be wrong.

  • Err actually both are not necessarily true. It is not difficult to find a situation where (a) the engine speed will decrease or remain constant; and (b) the speed of the car will decrease or remain constant when you floor the gas pedal (e.g. while going up a steep hill with a small engine or heavy load).

    The name "accelerator" is a bit confusing because it implies that it will cause your car to accelerate. More often than not, it's used to keep your car at a constant speed, and oftentimes it will be used to slow the car down. Most people wisely don't call it an "accelerator".

    Rather, most people call it a "gas pedal" and likewise use phrases like "giving it some gas" and "laying off the gas". This to me shows that they have a very good understanding of what the pedal does: it allows more gasoline into the fuel mixture. Also, it would seem that most people will not expect the gas pedal to cause any sort of positive acceleration when going up a steep hill (for example), so I'd say your assumption that most people just expect it to speed up the car is false. Also, your assumption that it doesn't matter would also seem to be false, otherwise extreme confusion would ensue when people would drive in hilly or mountainous parts.

    This may seem off-topic, but it's not. Would it be too much to ask to give the populous at large the benefit of the doubt? Most people know what's going on with most things, and they don't need it to be overly dumbed down. The worst case of this is retarded software companies who make programs that mimic real-life devices in order to presumably make it "easier to use" (examples are CD players which look like real CD players, chat programs which look like telephones, e-mail programs which make analogies to snail mail protocols). Oftentimes, the program will be come out extremely crippled, and pretty much inferior in every way to its competitors. Also, it come out being a little bit condescending, which I'm sure can't help its sales. People know that an increase in gas in the fuel mixture in their car causes an increase in power because they've experienced it, not because there's a sticker that says "speed" or any such nonsense pasted on to it.
  • Not automatically: the items still have to be selected in order to be viewed. However, that's enough for the script to run and capture session data.
  • I have done a web based email reader recently, and the unique cookie assigned can only be used by the ip address it was issued to. If some other ip tries to request a page with that cookie, it gets rejected. Such a trivial technique, works well too.

    Proxies of course make it look like everyone has the same ip, but this uses SSL which normally doesn't get proxied.

  • Just the addition of an IP address encoded as part of the session key will block out *most* of the people who could grab your cookie for this hack. The only ones it doesn't affect are those with the same IP address as the unsuspecting Hotmail user, which would occur if the Hotmail user was behind the same proxy as the perpetrator. Its an easy change to make, since they are (assumedly) already going back to verify the session key in some respect.
  • Write a Javascript embedded in an HTML that automatically sends the reader to another website. How much damage can you do to a person's PC once they get to a website? Especially with Java or VB/JavaScript?

  • People don't want to face decisions.

    Unfortunately, software requires you to make decisions, and dumbly clicking on "OK" all the time is seen just as a quick way to make the problem go away. Unfortunately, it's not the case. Ideally, the user interface of an application should be engineered and designed to stay flexible intuitive, easy to learn while popping up the minimum number of questions. These goals cannot be accomplished all the times for every situation. In such cases, where the full attention of the user is needed, I'd suggest to force him to use a different input device in order to proceed than the one he usually uses. Today it would mean that you'd have to require confirmation via keyboard (perhaps requiring to type an extensive `yes' instead of a simple `y' (or whatever). I know this may be source of troubles, but I don't see alternatives if questions can't be avoided.

  • I developed it on paid time, it was company property. I didn't keep a copy (I don't use Windows at home for anything but games, so I wasn't tempted).

Instead I got a pat on the back from the guy in the next cubicle (who didn't install the software either), and the company refused to hire me as a regular employee when my co-op term ended (despite demonstrated ability as one of their best programmers, and their desperate need for a rewrite of an in-house package I was intimately familiar with, I was "unqualified" without a degree).

  • How does it make you feel when so many here blame Microsoft Outlook for the ILOVEYOU virus. The prevailing attitude is "Microsoft should have protected users of Outlook. Instead of calling it Outlook, better call it Lookout", etc.

    What they are really suggesting is that Microsoft should bundle anti-virus software with Windows and Outlook. Seems to me that the bundling issue got you guys into a bunch of trouble already.

    You can't have it both ways folks. If you are going to split Microsoft in two for bundling software, you can't demand that they bundle more software to protect from virii.

    Ugh. Expecting anything but bigoted bullshit about Microsoft from /. is asking too much, it seems.

  • the tricky part about this is that you don't need to click on the attachment. Hotmail, just like many of the other newer email clients, recognizes it as html code, and embeds the html page into the page automatically. Unless you've changed settings, this will happen without you actually doing anything.

    it's not a vbs file. it's an embeded javascript. there is no virus check run because it's not a virus and there isn't an anti-virus that checks for potentially malignant javascript. Hell, the creator only had to identify the cookie, the username, and the server the cookie was being held on, and automatically send all of this info to another account (which could have been a hotmail account)

    Not everyone had to actually open the attachment.

    This is an embedded javascript exploit, just like some of the earlier exploits (not VBS as described above by CT). Hotmail is filtering out javascript within the bodies of e-mail, but not attached html files. They could remedy this by either filtering attached html files (not so easy to do) or by offloading the attachments to be read from a seperate server outside the *.hotmail.com domain (my recommendation).


    Here's an awesome story [wired.com] about another risk of using web-based e-mail. It describes how your IP address could be identified if the sender attaches an IMG tag to the e-mail and then watches the web server log for when you read the mail and your browser requests the image from her server. Clever.

    You punk kid virus writers are becoming lazy no-goodniks who just want to live off the government dole!

  • theres a Wired [wired.com] article and a ZDNet [zdnet.com] article.

    From the ZDNet article:
    Bennett Haselton, Webmaster for Peacefire.org, said the flaw involves sending a user an e-mail with an HTML attachment. When the user clicks on the attachment, the file sends a copy of the user?s cookie to the hacker.
    Once that cookie is received, the hacker can insert it manually into the Netscape cookies.txt file and use that authentication key to log in to Hotmail as the user. Click here [peacefire.org] for a description of the trick.
    <snip>
    Not a 'trivial bug'
    Since the cookie does not contain the user's password, the hacker can only access the account when the user is logged on and as long as the authentication code is valid. But Haselton said that five minutes would be long enough for a hacker with a prepared script to download all of a user's e-mail messages.

    Best I could see, theres no email floating around doing this - its just an idea at this point. And for it to propagate(sp?) like luvbug or melissa, it'd need a script to use the hotmail address book. As it sits right now, it'd just come from one guy who knew lots of hotmail addresses. Someone correct me if I'm wrong on this, tho :)

    How this seems to work is that someone emails you an HTML file as an attachment.

    If you then view the attachment through Hotmail, Javascript in that attachment can then pretend to me from the Hotmail domain, and therefore access any cookies that Hotmail has set up. It can then submit these values to a form on another, hostile, server.

    These cookies then allow access to the site from a user pretending to be you, allowing them to read and delete your emails or send email from your account.

    It's not clear form the article, but presumably the relevant cookie is the one holding the user's session key. In a typical implementation this key will be useless after 30mins or so, but the length of the timeout is really whatever Microsoft chooses it to be.

    Try logging on to Hotmail, not touching anything for 30 mins and then clicking on 'read mail'. If they have the server set up sensibly, you'll have to enter your user name and password again.

    On the other hand, if Microsoft have done something really really dumb, like including the password in a cookie, then there's really no hoe for them.

    Your post underscores the fact that many technical people have forgotton the original meaning of the words they use. It's really a shame.

    To you and me, formatting means erasing. But that's only true in techno-speak. In every other context, the word "format" does not imply erasing - not at all! And since very few people actually format their hard drives (and hence, have no experience with the process), how can you expect them to know what that word means?

    When you "format" something, you arrange it. You put it into some kind of order. To most people, that's a good thing! The moron who decided that "format" is a synonym for "erase" should be shot.

    If your application had asked the user to "erase all files on your hard drive", I think very few people would have said yes.

  • I've had a hotmail account for about 3 years and I still use it.

    Everytime I sign up for anything on the internet, anytime a webpage asks me for email, any time I have to put in an email address to 'register' a program, or any convention I sign up for, I put in my hotmail address... They then usually ask me a bunch of personal questions. I'm always 25-35 male, I make $100,000+/year and am single. And when you see all those little boxes where you check off your interests? Well, I check them all. Then I check (or uncheck) those boxes that ask me if I want their monthly, weekly, daily email magazine. Oh, and I want all the updates whenever they update their software/web page, etc...

    I currently get 7-8 emails a day at that address.. about twice a week I get one from Hotmail Staff telling me my mailbox is full.. :)

    what's wrong with using the password for a permanent cookie? someone with the cookie can do anything you can do (post comments, submit articles), so why is it a big deal if they have your password?

    otoh, for something like web-based e-mail where you log in for a few minutes, you want the authentication gone when you leave the computer.

  • The proper extension for a Word file with macros is ".dot", because it's a template (a Word template is a dynamic object which produces documents, a Word document is a static object and can't contain code) - just because Word is too stupid to complain if you name it ".doc" doesn't change that. What you're saying is like insisting that a ".jpg" can hold formatted text, arbirary JavaScript, and hyperlinks because if you rename an ".html" file to ".jpg" IE will still open it as HTML.

    At any rate, my program detected macros in files with the extension ".doc". It wasn't a program idea, it was a working program that I tested and proved effective.

    From http://www.emergency.com/wordvrus.htm [emergency.com]:

    An important point to make here is that Word documents (.DOC files) can not contain macros, only Word templates (.DOT files) can contain macros. However, it is a relatively simple task to mask a template as a document by changing the file name extension from .DOT to .DOC.

    I hate pathetic morons who go around insulting people for imagined mistakes without checking their facts.

  • Comment removed based on user account deletion
  • At a certain large Canadian technology company, after having the email shut down by a Word macro virus panic, I once wrote a program that identifies attachments with a ".doc" extension that are actually ".dot" files (Word document templates that could contain macro viruses). If it was a real ".doc", it just opened the file with Word; if it was a ".dot", it put up a dialog box with big biohazard signs that said "This is a falsely labeled file! It could carry a virus or trojan horse! ARE YOU SURE YOU WANT TO OPEN IT?"

    Everyone who saw it, including my boss, agreed that it solved the problem completely. However, nobody installed it, and nobody outside of my department was shown it. It was almost certainly deleted shortly after I left the company, and the vulnerability (to a few specific viruses) solved several months later by purchasing expensive anti-virus software.

    Home users have an excuse: most of them are ignorant. They have a vague idea of some portion of what's on their hard drive and what's on the internet, and of the difference between an application and a document. Corporations, though, want a simple solution: money out, invulnerability to viruses in. The answers have been jumping up and biting them on the nose from any halfway decent MIS department, from security websites, from annoyed articles in the trade papers, but the managers involved want their computers to "just work", and not be bothered with having to think (or making all their employees apply common sense, which, I must admit, is about as difficult as teaching cats to march in formation).
  • My wife uses Hotmail, because she likes the convenience of getting her mail through a web browser, from any computer. I've seen a few apps for Linux that allow you to pull your mail off a POP or IMAP server, and access it through the web (ACME mail comes to mind - http://www.astray.com/acmemail/)

    Has anyone used this, or similar programs? How well do they work? How insecure are they?

    Oh, yes. I've actually suggested we do something similar at our company. We send out HTML emails to our customers. The URL in the IMG tag doesn't have to be an image at all--it can be a CGI page which redirects to an image. Throw a couple of parameters (like a user-id) into the URL, and the CGI page can record exactly when users open the email. Nifty, eh? I never thought of capturing the IP address directly (not something we're interested in) but it would obviously be possible.

    Wonder if this could be exploited further?

  • I wrote a little "application" that was a simple little dialog box that asked the user if he wished to format the hard drive (in so many words) to see just how many of our in-house users really read those messages - and attached it to an email sent to everyone in the office (around 150 users). (Results were then sent to my computer through TCP connection, for those interested) 1 out of 3 users clicked yes..
    Did you then go back and resolve the IP's to machine locations and send anonymous emails to the users saying "You, sir [or madam as the case may be], are a FOOL!"?

    Why would anyone in their right mind let unknown people run foreign code on their machines? Yes, I get executable attachments sometimes myself, but why would I want to run code that does who knows what? I guess I just know too much about the kind of people out there. Yeah, maybe that's it.

    Just goes to show, once again, that there are two kinds of people in the computer world -- those who know what they're doing and understand the technology, and those who are along for the ride and depend completely on their "gurus" for anything even the slightest bit off the routine.

    I have to rant a little about this because around here 9 times out of 10 people come to me to bail them out when they screw something up, and only one of my jobs pays me for that. I have very little trouble believing that quite a few people would answer "yes" to your question, and not much more trouble believing that they would come whining to more clueful people about getting their files back afterwards.

    ("No, you don't understand. You FORMATTED the hard drive. That ERASES the hard drive. Unless you backed up those files which were ON the hard drive, they're gone. Sorry .. have a nice day ..")
  • So I just tried to send a message through hotmail, and I got a 404-ish error. So I logged back in to Hotmail and later got a message while refreshing saying that the server holding my account was temporarily unavailable. Sounds like they're taking the machines offline to throw in a patch.

    I'm hella pissed, though, because the mail I was sending was to a headhunter I've been talking with about a sweet Linux job and I don't know if it went through or not.

    It's enough to make a person switch over to PEmail. Old habits die hard, though. I've been using Hotmail since before M$ bought them.

  • Actually, 'format' is not a bad term for what it was intended to do.

    But that's beside the point. The fact that it re-initializes the directory structure and allocation tables is nowhere near as big of an issue as the fact that it erases all data on the drive!!!!

    Here's an analogy:

    Stepping on the accelerator in a car will:

    • A) increase the RPM of the engine
    • B) make the car go faster
    Yes, both are true, but so what? When a driver steps on the accelerator, it's because he wants B) the car to go faster. 99% of all drivers aren't that concerned about the engine RPM, even if they know what it is.

  • People are lazy and don't consider the ramifications of what they do. This puts more burden on programmers to protect idiots from themselves.

    There are many alternatives to Outlook Express (in the case of the love bug) or Hotmail, but people that are too lazy to properly evaluate the suitability and safety of their tools will get hurt. This happens with physical tools

    That taiwanese-brand hammer is way more likely to split and send shards into your eye, but is that your fault or the manufacturers fault? In the US, it is of course entirely the manufacturer's.

    It's not the grammar that bothers me, so much as the inaccuracy of the summary. It isn't a VBS attachment that causes the problem, but rather a plain HTML attachment with embedded javascript. Even in a world of "intelligent" users, HTML is expected to be a "safer" document format, rather than "dangerous" executable code.

    I think there're a number of people you could assign the blame to, but no one entity that's "fully stupid". Users should be more careful, Hotmail should attempt some filtering, but most importantly the w3c should provide a means of denoting "third-party" HTML (and other documents) that appears to be from the server, but in reality was placed there by someone else (such as an attachment to an email or a comment in a message board that doesn't restrict HTML).

  • How's "resetting the filesystem" for a name?

  • Most people wouldn't think twice about opening a snail mail package addressed to them, even if it has not return address on it, and seems somewhat heavy. That's why the unabomber managed to rack up a pretty decent string before being caught. People don't tend to think that bad things will happen to them when they are using tools that they deal with everyday without understanding.

    To put it another way, while most people think of themselves as fairly decent drivers, how often in the past week have you been cut off, or had the guy in front of you make a turn without signalling? People get so used to using tools that they become careless; this is compounded if the person doesn't understand how the tool that they are using works, or at least had it drilled into their heads the way to safely use the tool.

    It's just a matter of time before people get more careful about opening things they're not sure are safe. I imagine Thag got a lot more careful with fire after watching Thog torch himself.

    Contrary to the reporting on /., the most recent Hotmail hole is in no way related to a VBS script. What's so alarming about the hole is that it is acutally an HTML file which contains the exploit. More specifically:

    The folks over at Hotmail were smart enough to filter out JavaScript from HTML formatted messages sent to Hotmail recipients. They did not, however, think that it would be necessary to filter HTML attachments, either. As a result, a clever individual was able to construct an HTML page containing JavaScript which forwards HotMail authorization cookies to a third party.

    Ironically, this information is largely reproduced from the article on Peacefire [peacefire.org] cited in the original post. No mention of VBS files anywhere.
