New IM Worm Installs Own Web Browser
Aquafinality writes "A new IM worm discovered recently takes the novel step of installing its own web browser onto the victims PC. Ironically titled "The Safety Browser", its default settings actually make your PC less secure - switching on pop-ups, changing your home page and hijacking your desktop with a looped music track that plays every time you switch your computer on.
It's clear people cannot resist clicking "yes" to anything they're presented with via IM - with this in mind, what on Earth can we do so stop the spread of garbage like the above? To put it another way, will reducing the amount of potential "suckers" out there dissuade the bad guys from coming up with ever-more elaborate ideas such as this latest scam? Or is IM safety a lost cause?"
It's very hard to stop people executing something thats sent to them by someone they know - but for other vector methods, perhaps people should consider an IM client that doesn't include activeX
Anyway, mildly interesting, the worm makes no attempt to hide iteself with a "You are beaten, it is useless to resist" desktop paper (!) and music on startup (from TFA) Worse still, music starts to blare out of your PC. Not just any old music - bad music. Bad looped music, with screeching guitars and awful drum n' bass beats.
But not to worry XP SP2 users, you're protected.... again from TFA: snigger....
There are shills on slashdot. Apparently, I'm one of them.
Make "Yes" buttons, by default, HURT people physically.
I think safety is always going to be hard to push on people who don't seem to understand the importance of what you are telling them. I'm sure you'll know from your own experience how hard it is to get even your own parents to take adequate security steps. I don't understand what this virus is doing though surely you would notice a new browser and remove it? certainly not use it...
As for removing the incentive for people to do this I think it will be hard; there will always be a few "suckers" and even 1 in a million can be profitable; so it'll be hard to stop it.
*''I can't believe it's not a hyperlink.''
As others have said, and no doubt will continue to say, you will not change the masses' behavior. The problem is not that people will click on things that look interesting, the problem is that the program will execute something presented to it.
There is no reason that *any* instant message client should ever execute other code, privileged or not. That is not the purpose of IM- IM is not a program launcher, it is a tool for communication.
does the browser pass the Acid2 test?
The difference between stupidity and genius is that genius has its limits.
Next month, an IM worm will install not just a browser, but an entire operating system. It will be Linux, but it will be setup to give the worm owner complete remote ops. It will have basic mail, IM , web browsing and word processing all via the usual open source tools, and will be made to look something like Windows. And 90% of the people who wake up to find this new OS running on their system will simply use it.
You KNOW they will. That's the level of what we're talking about.
For one thing people have become accustomed to random stuff showing up on updates and upgrades. The remore operatior will simply launch a splashscreen that says "A gift from Microsoft for your loyalty!" and people will go nuts. For another thing, there is a good deal of evidence accumulated over the many years of this malware war that the users who are keeping malware authors in business are total noobs. Many are developmentally disabled, or are children, or are computer phobes who avert their eyes when the machines "does something odd". Some are simply dumb as cabbages. They click "yeah sure, pwn me" on every dialog box because they are functioning as part of the attached peripherals a NOT an intelligent user.
No, I'm not bitter. I'm not being sarcastic. I've woken to the reality. This is our world, and we white hats are just a liitle slow on the uptake is all. What this suggests about computer ownership (like maybe you need an operator's license, as required with radio broadcasting, if you are going to traffic in the public sphere) is probably the next frontier of the discussion, that's all.

I mostly agree with your post - and you put things well, but:
:-)
Probably not, because the typical default access for a linux user is unprivileged (I've been working intensively in the linux environment, and I'll bet I've not been logged in as a privileged user (i.e., root) more than two or three times a year during that span).
I'm not sure how long user privilege separation is going to continue to be the great protection it is now, once the majority of desktop users have it. Consider a single user desktop with privilege separation (linux, vista (supposedly) or os x):
1) Malware downloaded & executed by dumb user.
2) Malware sets itself to start at that user's privileges when the user logs in.
3) Malware can do many things at malware level at least when user is logged in (including periodically checking its update server for local privilege escalation exploits it can run).
We're about to enter an age of smarter malware, that takes its time getting root, and keeps a low profile (maybe a little keylogging here or there) until it does... you read it here first

Split the friggin' internet in half.
Give out odd numbered IP addresses to Linux users, and even numbered addresses to Windows Users.
Then Linux computers just turn off access from even numbered source addresses.
Problem solved.
Ok - time for bed.

Internet Explorer 7!
We can browse if we want to,
we can leave your friends behind
Cause your friends dont browse and if they dont browse
Well theyre are no friends of mine
I say, we can browse where we want to,
catch a virus we will never find
And we can act like we come from out of this OS
Leave the real one far behind,
what on Earth can we do so stop the spread of garbage like the above? To put it another way, will reducing the amount of potential "suckers" out there dissuade the bad guys from coming up with ever-more elaborate ideas such as this latest scam?
Clearly there isn't enough evolutionary pressure on the heard. What the good guys need to do is build computers that explode when the user does something stupid.

Silver Clipboard: Time Management Tips
Maybe we can't put the genie back into the bottle, but I think the real problem is that every Internet-enabled application these days is bastardized into a file transfer mechanism. IM programs should be for typing messages back and forth between two or more people. Why should IM even have the ability to transfer files?
I think using virtual machines as sandboxes could go a long way towards improving security also. Imagine a distro with a super-locked-down secure OS that only ever runs a single app, which is a virtual machine app (VMWare, Xen, whatever). The user does everything inside this virtual machine's guest OS, and never installs or runs any other software on the host OS.
With that setup, it would be easy to "checkpoint" the state of the system and restore it whenever things have gone wrong (due to malware, user mistakes, whatever). (A clever diff-based mechanism might be able to make OS-state saves/restores fast enough to be done automatically in the background, say once a day). Even if the guest OS was completely compromised by malware, it would still be impossible for the malware to prevent the user from using the (uncorrupted) host OS to "rewind" the computer back to before the infection occurred. The host OS could also keep an audit trail of what happened when inside the guest OS, to help the user find out where things went wrong.

I think most people that stick with ms software do this because they have no clue how to install alternative software (seriously - my family uses PCs for 14 years now and still they call me and ask me how to install this and that software) so make a "worm" that assists you in making your pc more secure (and shows you that you need it at the same time) maybe put in links to small, easy-to-understand "getting started" sites...
The MAFIAA is a bunch of mindless jerks who will be the first up against the wall when the revolution comes
Does anyone have a link to the really bad music this worm subjects its victims to? Hearing it would seriously enhance my sense of schadenfreude...

Maybe so, but the rest of us don't deserve what we get. Even if I'm a careful computer user and never get compromised, I still have to deal with the resulting spam, DDOS attacks, increased IT costs, etc, caused by people who do. Therefore it's in everybody's best interest to make security more idiot-proof -- we can't just say "to hell with the n00bs", because we still have to live on the same Internet as them.
I don't care if it's 90,000 hectares. That lake was not my doing.
Disclaimer: My experience is with VAX and Unix boxes in the eighties, my first Linux kernel was 0.9something but I have used Windows only since 98SE. I never really got to "learn" windows and am much less clear on the internals. On the "how is this supposed to work".
With more than two decades of serious computing behind me, I still do not understand what "Administrative privileges" really means in Windows. Or what it is good for. In U*X everything is a file and thus those magical "privileges" simply boil down to what you can do with a file (including files in /dev, /proc, directories in general, etc). There's a layer of abstraction where I understand that access to this 644 means that I can only read it, but the owner can write to it as well. That's easy.
In windows, it has never been terribly clear to me -- there appears to be some nod in the direction of file permissions, but all I've ever seen of them is that sometimes I have trouble messing with something the wife has been working on -- that kind of thing. Sometimes there's no problem. Sometimes logging in as admin solves some problem that I have but I hesitate to do so since I nevere really know what Windows does behind the scenes that might become a problem if I were to be logged in as Admin.
In the end, the preferred way to do something that I can't do as user is to fire up cygwin and do it from the linux prompt.
And ours is the rare enlightened case where someone took the trouble of setting up user accounts at install time. It was certainly not in the least obvious when and where to set up this kind of thing. I cannot fathom why I would've bothered with it if I hadn't had a Linux backgroud. It's not like XP pops up a screen during install explaining what an Admin is and how he is distinguished from a normal user.
I still see people on older machines where they haven't even bothered to configure users for their older Windows machines... and don't have the slightest concept of partitioned separate logins for distinct different users.
Of course not - why would they? This is my computer, I'm the only one using it, if the kid gets old enough to want to diddle with it I'll buy him his own computer. Why would I be setting up different "users"? I doesn't make sense in the Windows model.
U*X (and VMS and ...) was developed in a networked multi-user context of universities and research labls. Windows was developed to make one computer do one thing for one user. "Multi-user" is an afterthought. Network security is an afterthought. The entire computer-as-an-appliance model of how a computer should behave in Windows just doesn't lend itself to the notion of a "privileged account". You don't have a privileged account in your toaster or your microwave, do you?
Now it gets hairy: If I grant for a moment that there's no such thing as absolute computer security, then all these unsecured windows boxes out there are just the low-hanging fruit. Viruses and worms are only as smart as they need to be to pick those. This is fine with me as it means I merely have to have my fruit hanging higher than everybody else's. My house doesn't have to be absolutely burglar-proof -- just harder to break into than my neighbors. I'll never be perfectly termite-safe, but as long as I'm more termite-safe than my neighbors, they will attract all the termites. You get the picture.
If geeks succeede in training the masses in making their machines "more secure" it only means that the malwa
We're all born with nothing.
If you die in debt, you're ahead.
Why? Because it becomes just another hoop to jump through. They don't consider the implications behind their action. The computer wants something, they give it what it wants to it'll shut up and let them get back to doing what they want to do.
Admin passwords are useful for knowledgable users because if you do something that shouldn't require admiin, but asks for it you can step back and think why it's asking, and approve or deny it based on more information. However clueless users won't do that, they won't know what should and shouldn't need it, so they'll just blanketly issue the admin password.
I've already witnessed this on other platforms (MacOS) that ask for admin. I was chatting with a guy while he was tinkering with his Mac, it popped up and asked for admin and he said "Huh, that shouldn't need admin"... as he was typing in his admin password (3 letters long). He even recognised that this might be a situation where it wasn't needed (it was actually, nothing harmful) but just gave it the password anyhow.
So while I think the privledge escalation is Vista is a nice try, and certianly something I'll use personally, I think it will ultimately make no difference for normal users. They'll just make it go away whenever it pops up, and they'll do that by giving it the password it wants.
Not only that, but:
4) Malware can install a keylogger so that when the user legitimately needs super-user access, the malware steals the password
5) Prompt user for Admin password directly (or in the case of Ubuntu for example, the user's own password to run sudo)
6) Even if the malware can't create its own password prompt, but must use a system default prompt:
"Warning! A program is attempting to gain Administrator level access. This should only be necessary to install programs or perform other maintenance. Click Cancel otherwise."
1 -Malware prompts user for password with message above
2 -Naive user reads message, clicks cancel
3 -Malware prompts user again for password
4 -Ad nauseum
5 -User gives up and enters password
Privilege seperation can be useful for preventing automated system takovers, but where a user is involved (and that user can get super-user access) becomes moot.
Let me be the first to point out something..... YOU are a user. Yep So if all users and dumb, and you are a user, then you too are dumb. If you are dumb then your statement looses validity.
In my mind we need to drop the Microsoft/Apple attitude that users = idiot. If you build systems for idiots only idiots will use your system. Generally I've found that the #1 reason users I work with generally do stupid things because I've either, Improperly documented or explained what something did or how it worked, or because I created something that blocked their ability to do their job.
Very often users tend to view the people at help desks as idiots because regardless of problem the reaction and lack of willingness to care are obvious from the start. Even cultural attitudes are ignored in the move to "cater to the idiot who uses our product" In one contry clucking your tounge may be a sign of rapt attention. But in the country the user is in it may be a sign of a smug and condiscending attitude.
In one of the first lessons taught in management classes you will learn that a team of idiots is lead by an idiot. I claim that the same is true here as well. If you have idiots for users it's because you have idiots for techs.
I'm sorry, I'm to tired to be witty at the moment so this message will have to do.
