It would seem all that I was shouting about and had people shuting back at me for being chicken liken, seems to have unfortunately come to the attention of LL. /128/2b/204030/1.htmlI had asked this to be made sticky, but guess it wasn't hot news back then. Nobody likes to be right about bad news, but whats more painstaking, is that despite the overwhelming evidence I gave in the numerous posts I made, no one bothered to listen. This 'latest' exploit, although historically ver very old, effects rstp, turning that off (assuming you don't have Vista which locks it all), should perhaps make you sleep soundly, but I wouldn't put that as a safety thing. If you already have a bit of maleware (and 95% of systems connected directly to the intenet (not behind a corp firewall from a intranet) are already infected), that is probably feeding/sharing off your connection as you read this post. Your chances of infection are greatly increased if you frequent a Web 2.0 website (MySpace, YouTube etc..). Anyone can place unchecked media onto a Web 2.0 website and piggyback exploits onto your system beneath your firewall, and past your virus checkers etc. Some Tell Tale signs: When you play media in the quicktime player, open a movie inspector window, and the desktop icons begin to flash and text becomes corrupt... thats an exploit taking advantage of the icon cache to compile itself. When you play media files in the QT player, and you close the window, you get a message, 'buffer overrun'.... thats exploit code just finished using the buffer overrun memory to compile itself. QuickTime starts complaining that formats like mp4, mp3, mov aren't native formats and crashes the player. There are quite a few more besides. What can you do? 1) Hold tightly to your butt....If this is the first time you noticed any of the above behaviours, restore windows by at least 30 days. Dumping ANY media you have downloaded in the past 30 days. 2) Grab a copy of this: http://www.grisoft.com/doc/download-free-anti-rootkit/us/crp/0 install it, reboot. 3) Uninstall all media players (including windows media player, it will roll back to the default version), emptying EVERY cache (including SL's) and cookies, history etc... 4) Make sure you always choose 'Custom' in the windows update, and install any software and hardware updates. 5) Cold reboot into Safe Mode (windows), run deep scans with virus checkers, anti-maleware etc. 6) Install fresh copies of your players, one at a time and always reboot between each install. 7) Don't run IE and FireFox on the same system, a certain exploit can use the cache of the one not being used, to gather information about you and your system.  Don't click on links in emails, you cannot tell if they are redirecting you until it is too late, IE will decypher the DNS of a link, if you paste it into the url box directly, always check the Status bar in IE, for the translated address from a link. 9) Windows again (sorry Mac and Lunix users), Control Panel, Firewall icon, open it and click the Exceptions Tab, UNCHECK EVERYTHING in there, except maybe.. SLVoice (try it without checking it). If you want to know an easier way to become infected in SL.... the Web tab in anyones profile. You don't need to actually click that tab, just by opening someones profile, that has an active webpage, will be a easier way for someone to infect you. For a very few ppls, they have cute background music running from their index.html webpage, as soon as you open that page, the music begins to play, but wait... you only need to open someones profile for that page to begin to load and cache.... you didn't even need to click anything, you gave global permissions for anything to be loaded onto your system by opening up their profile!!!! Imagine the music being malicous code.. you wouldn't hear it, and you don't think you gave it permissions to run on your system, but you did! Forget the QT exploits, profiles are used daily by 99.9% of users in SL.

Big kudos to AWM for this advice. I opened QT to try to add the RSTP fix, and got the exact behavior he described. I followed his instructions re. deleting QT and other viewers, scanning for viruses and spyware. I also ran a registry cleaner after all the deletions. Not only did my new QT installation run without a symptom, a long-standing problem with my screensaver not turning on went away. Two fixes for the price of one!!

From: AWM Mars It would seem all that I was shouting about and had people shuting back at me for being chicken liken, seems to have unfortunately come to the attention of LL. Except that wasn't what people were complaining about, was it? It was the whole "you can get viruses by watching stuff on YouTube" thing.

If I have knowledge in assisting in correcting an issue, not just reporting it, then I do...
The thread started along the lines of enquiring how the particular website was uploading moves onto its servers, so we may submit some of our offerings, however this developed into a in depth, and sometimes heated, discussions regarding types of exploits/maleware and some of the potential sources. Web 2.0 websites being sited as being the most prolific and common sources, of which MySpace and YouTube are.
Web 2.0 websites are twin layered, the first layer is the delivery and hosting layer, the top layer is where users can upload their own content, which is potentially where the exploit loaded media can now deliver its package to anyone viewing the media. This process is totally unchecked by the company/organisation/individual controlling the first layer.
For the most part, the vast majority of users connected to the internet, are not even aware that their systems are infected, and eachtime they dispense something across the internet, they are spreading maleware. Maleware is a general term used for anything that is considered undesireable, that may result in some degree, and sometimes all, control of their system, being taken over. This can be something quite simple and at best annoying, to a more serious situation, where identity theft, connection sharing being used for multicasting porn or spam, are rife.
Keyloggers, redirecting connections, splitting connections, peering spam and or porn, virus infections and or propagating, disabling systems, trojans that allow other exploits to utilise your system or download and compile themselves that then propagate to other systems via your email or via Web 2.0 webhosts. The 'smart' exploits being spread these days, can easily bypass your firewalls and some can even bypass your virus checkers and adware software.

Embedded Quicktime video is not supported by the in-world browser, so the QT issue is not relevant as far as profiles are concerned. As for From: someone you only need to open someones profile for that page to begin to load and cache.... you didn't even need to click anything, you gave global permissions for anything to be loaded onto your system by opening up their profile!!!! Not quite "anything". If you disagree, go setup a website which will say..dump an exe file in my cache if I visit it via the in-world browser. Should be easy enough to repro, right?

You misunderstand the issue... as I pointed out, if you open someones profile that has a webpage linked into the web tab of their profile, which also (for the purposes of example) includes background music, you will hear that music. All you have done is openned their profile, not even clicked on the web tab, yet this code delivering a music file onto your system, begins without intervention. How long do you think it will be before someone who does malicous things, is going to see this potential exploit in the client?
As the vast majority of the SL community rely on openning profiles, this requires attention.
Short term fix: Uncheck 'auto load' in the web tab of profile, do not allow cookies and or browser cashes to load onto your system via the SL client.

Short term fix: Uncheck 'auto load' in the web tab of profile, do not allow cookies and or browser cashes to load onto your system via the SL client. I agree that the web tab is a nuisance, but I'm not sure I agree with your fix. (By the way: For over a year it hasn't been unloading itself (or the loaded web content within) when you close search, which makes it a bit of a resource hog in my opinion. To reclaim the memory it uses up (or just turn the damn music off), you pretty much gotta restart Second Life.) Anyway, like you I would rather the web page wasn't automatically loaded by default, but a message box displayed whenever the user clicks that web tab - warning me that I'm about to view external websites out of Linden Lab's control. Perhaps with a check box saying "don't show me this message again". You know, the way Microsoft and Mozilla do it. The audio you hear in those profiles is being delivered via Flash by the way. Media players like Quicktime, WMP, Real, etc., etc. are simply not supported and I doubt they ever will be, making the mini-browser safer than most. Also, if uBrowser ever hits the grid, webpages (with Flash content) are going to end up as textures on prims. Your proposal therefore upsets Callum Linden's apple cart, so I wouldn't expect a resolve any time soon. More on uBrowser (web on a prim) at http://ubrowser.com

I seriously do not understand why cookies and auto load website profiles are "on" by default!
