New Email Worm Squirming Through Windows Users' Inboxes 473
Trailrunner7 writes "There appears to be an actual email worm in circulation right now, using the tried-and-true infection method of sending emails containing malicious executables to all of the names in a user's email address book. The worm arrives via emails with the subject line 'Here You Have' or something similar, and the messages contain a link to a site that will download a malicious file to the victim's PC. The malware then drops itself into the Windows directory with a file name of CSRSS.EXE, which is identical to a legitimate Windows file. From there, it's 2001 all over again, as the worm attempts to mail itself to all of the contacts in the victim's Outlook address book."

I have no idea why you were modded "Troll" except that some people have an irrational oversensitivity to any mention of the iPod or iPad. They should get the fuck over it, to be direct about it.
Back on topic, what you mention is a very good idea. It's also not new to Apple products at all. That's the approach Unix has used for a long, long time now. Installed programs on a Unix system are generally root-owned and sit in directories that are also root-owned. For a normal user, both the executable and the directory in which it is located is read-only.
The problem with Windows is the vast amount of software that is poorly designed and wants Admin privileges even though it could be designed to carry out its task without them. This has trained the more point-and-drool type of user (the majority who gravitate to this platform) to just click away any dialogs without seriously questioning why a program is requesting extra access. That is, of course, assuming they are running as a non-privileged user in the first place.
The iPhone (I assume you don't intentionally refer to an mp3 player) approach is more like "you don't need root for anything, let us manage that". The Unix approach is more like "programs don't expect to have root privileges without a very good reason, like your package manager for example". In both cases an e-mail client would be run as a normal user. I'm not so familiar with the inner workings of an iPhone but at least on Unix and Unix-like OSs, the binary executable file would also reside in a root-owned directory not writable to any normal user. Combine that with the generally more clueful user base and it's easy to understand why Unix/Unix-like users just don't have these problems.

It's certainly possible for a Linux user to download an executable to his/her home directory and run it. That was GP's point.
Sure. For that matter, it's possible for you to deliberately chew on broken glass. So what? The point is, Linux users have little or no need to get their software that way.

It's not so much about whether you should be allowed to do with your own property what you wish. Of course you should. It's more like the security model of capabilities. If there is no good reason to allow something to happen then it is better security not to allow it.
This breaks down in Windows because Windows does not have a centralized package manager that handles both the installation and the uninstallation of all new software. The proprietary nature of most Windows software would preclude such a thing. A Linux user can have the full use of their system without ever having to directly download a binary executable and then run that executable just to install or use a piece of software. Instead, they have package managers and repositories which have all but eliminated the issues of third-party malware.
By contrast, on Windows it is far more common to directly download an "Installer.exe" file and then run that installer in the directory into which it was downloaded and with the elevated privileges needed to install software. That introduces problems when such executables come from untrustworthy sources. Introducing undetected malware into a Linux repository is much more difficult and thus has occurred far less frequently than the much easier task of conducting a social engineering attack against a user of an e-mail client.
The way things are done on Windows makes it far more prone to these attacks. The fact that the average Windows user is much less knowledgable than the average *nix user compounds the problem. That's why you have attacks that are about nine years old that are still successful, which is really quite pathetic.
Re:So that's why the UW mail system went down (Score:4, Insightful)
I am aware of the basis of your questions; what I am saying is that fact that normal, non-technical Windows users often don't have someone else to administer their machines means that they have to be able to run executables from directories that they can write to.
Now, distinct security roles for the same user can mitigate some of this is risk, and it might make sense to not allow a normal Windows user to run code that they have "casual" write access to (e.g., without escalating to an administrative role temporarily), but the problem with that without is finding a way to make the security model simple and comprehensible enough that users don't simply get into the habit of escalating to an administrative role to do things without understanding what they are doing.
This is not a particular easy problem, because for a general purpose computer, you have to have a fairly fine grained security model to allow software to do what the user wants it to but not other things, and non-technical users aren't going to want to learn the details of a fine-grained security model.
I don't think that's really all that true; if Linux becomes popular enough with casual users that the kind of malware that is directed at them becomes worth targeting at the platform, third party repositories will be setup and emailed invitations distributed to add them and download screen savers and other seemingly-innocuous software from them. Which will, of course, be malware that the users are being tricked into installing with elevated privileges. (Of course, you can install packages on Linux straight from files -- even files in email -- since, e.g., Ubuntu, IIRC, runs the graphical package manager by default if you click on a .deb; while many Linux systems have security models that are somewhat better than Windows, I don't think they are all that much more secure against social engineering directed at non-technical users with administrative rights on their own boxes.)

No, it does not. The only real barrier to something like that on Windows is the usual cries of "monopoly", which tend to be louder on Slashdot than anywhere else.
If Microsoft released Windows with a default configuration that could only install applications they approved of, Slashdot would be in a state of apoplectic outrage, even if it was trivially simple (say, a checkbox in a control panel) to turn that feature off (that is to say, defeat the purpose of having it at all).
I think you fail to appreicate the proprietary nature of most Windows software. Even the freeware is closed-sourced and copyrighted in such a way that you are not authorized to redistribute it. That means you cannot legally operate a repository containing a library of Windows software from a single source, because you'd have to get written permission from the authors of each individual piece of software allowing you to redistribute their software from your single source. It'd be an absolute nightmare and one mistake would make you end up on the wrong end of a lawsuit.
That is, of course, not beginning to address the issues surrounding the redistribution of commercial for-pay software. Redistributing that without the express blessing of the creator is usually called "piracy" and may be severely punished by the civil courts.
The only way around this would be for Microsoft to create a walled-garden type of environment sort of like Apple's App Store. Then they could dictate what licenses and/or terms of copyright are and are not acceptable. But you better believe that this would raise monopoly issues when that single vendor controls over 90% of the marketshare. Want your software to reach 90% of all desktop users? Then you play by their rules, or else. At that point the software license is no longer between the vendor and the user who is their customer; Microsoft is now the referee whether or not this is against the will of the vendor or user.
You may characterize concerns about monopoly power as categorically illegitimate and overblown in all possible cases. I do not. It is not desirable for anyone to give Microsoft that kind of power over that many users. Centralized package managers just aren't compatible with monopolies and proprietary licenses for a wide variety of good reasons that aren't just going to go away.
A centralized package manager for Windows is such a great idea that it would have been implemented by now except that there are some damned good reasons why such a thing is destined to fail miserably.

Before the collective wrath of Slashdot falls upon an innocent* cyber squatter, bear in mind that the URL listed in the text of the email wasn't actually the URL that the href linked to (text claimed to point to one spot, actual href tag pointed some place completely different). It didn't link to a PDF either but an executable with the .scr (Windows Screensaver) extension.

Lulz @work today (Score:5, Interesting)
Initially, got a few batch of these at $work$ today -- one of the remaining 800lb Wall Street gorillas. The mails originated from some senders @NYSE, and were sent to some internal mailing lists.
It didn't take long before a bunch of our own drooling baboons clicked the link, causing more mails to go out to the internal lists. That went on for a few hours. Then came the inevitable "why are you sending this", "i must've gotten this by mistake", "take me off the list" replies from more internal senders, resent to the same internal lists. Then came the inevitable "this is a virus, do not reply to all" replies to all.
I told my management that what they have in their inbox, basically, is a list of people to get the axe when the next round of layoffs comes around. Can't create a more accurate list of people who are truly the bottom of the barrel, and do not belong in an organization that's supposedly charged with with billions of investors' and depositors' money.
P.S. -- I also thought that this was the exploit for the 0-day PDF flaw too, given the .pdf extension. But if this was just an ordinary executable, that you actually had to click through an extra time to execute, then there's even less excuse for anyone with a brain to get infected with this.

But seriously, how is that a non-relevant criteria? Especially if you had somebody who has done it multiple times, that is a major risk to the company's network. Especially for a company with people's financial information, you can't have people downloading such ridiculous things.

"Download"? (Score:3, Insightful)
...the messages contain a link to a site that will download a malicious file to the victim's PC.
Shouldn't it be that the site uploads a file to the PC, while the PC (or the worm itself) downloads it?

Depends on Who Patient Zero Is... (Score:5, Interesting)
I got one of these at work.
The reason it didn't nail my machine is because...
1. I have HTML disabled on Outlook
2. I never click ANY links that go outside the company.
I did a quick search on the URL, and it led me to Slashdot in the Google results. Yay Slashdot!!
But here's the catch? Someone INSIDE the company *did* get hit, and it spread from their address book to everyone else. That's the usual progression, of course, but the source and headers actually made me look twice.
ALL of the headers, everything, came from inside the company firewall. I could see where it passed through at least 3 firewall systems to get to me.
When I spoke to network security, they said they'd been fighting it since noon. The reason why is because people are actually READING THE HEADERS and checking the user, and it's coming up legit!
The folks on our end are actually doing due diligence, they're just not paranoid enough.
Re: (Score:3, Insightful)
You know, all that due diligence makes perfect sense right up until you get to the fact that the "document" or "picture" you were sent isn't actually a PDF or image, but a .SCR - a PE-format executable binary. Windows will bitch at you about 3 different ways if you try and run one of those off the web, and the simple fact that it didn't just open in Adobe Reader should be more than enough of a tip to click no.
Personally, I suspect the people at your office are simply lying about checking the headers and all

You use what the company tells you to.

This wasn't an .exe file. It was a .scr file that was encapsulated in HTML to make it look like a .pdf. If you had HTML enabled, you'd only see a .pdf.
- What retard still opens links it receives in e-mail?
If I wasn't a paranoid security-nut, I would have. It came from inside the company, from a legitimate user I'd been in contact with in the past. But because I'm paranoid and have HTML disabled in Outlook, I could see the REAL link going to someplace in the UK.

Have you got something better that can support 150,000 unique email addresses in the United States alone????

They're called "distribution lists". When the bad guys get inside, they work just as well for them as they do the user.

I wonder why you got modded so high. Do you have any clues about email systems?
1) Support for 150,000 unique email addresses: There is no need to use unique in that sentence. Also support for what? Even my texteditor can hold that many email addresses (unlike notepad) and since it is unicode based there is no difficulty adding other countries usernames. So what the hell do you mean by support for 150k email addresses?
And why should it be a problem at all for any system? MTAs and MDAs are limited by the amou
