Malicious JavaScript code,

[Noone Here]

AIUI, it was not all that long ago when the threat to personal users,
was attachments that when executed compromised machines with keyloggers,
trojans, etc.

Now it seems that the big problem is reading a webpage or an HTML e-mail
and getting affected through the scripting. My understanding is that
the script downloads the malicious program from the web and sets it to
run on start up through the start-up folder or in the registry.

I don't know much about this; can someone suggest a good web site to
start learning a bit more about these threats. I have googled, but I am
not quire sure of the best search terms, and since there is so much
information out there, a site that experienced people endorse would be a
lot of help.

In particular, it seems as if JavaScript dowloading a trojran without
the user clicking an attachment is a big problem.

Thanks.

Using javascript is just one of many ways of writing codes that will
cause computers serious problems. Others include ActiveX, and just
corrupted images with bad code hidden in them. At one time you could
avoid bad sites and not open unknown email, and you usually would not
get infected.For some time now there have been bugs that will infect
you just if you sign onto the web. Especially if you have a Windows OS,
you must take all Microsoft critical updates, have good virus
protection, have a good firewall, and keep them all updated. Else you
most likely will be infected soon. Some of the anti virus programs have
links that will allow you to find what new bugs are out there and will
describe an old bug for which you have found a name.

I am like Hywel on this one. I would like to see some examples, or an
explanation, of your claims that JS "will cause" (not "can" cause)
serious problems. And as well as "just signing onto the web" can infect
my PC.

A very early JS exploit used script to open the Netscape home page in

Rather than playing child-like pranks such as the above, the modern
hacker may not want you to know your computer is infected. He or she
may be more interested in making your computer a zombie to send out
spam email or to obtain your personal information such as various
account numbers.
Also give some detail on how "just sign[ing] onto

McAfee features a different bug on their security center home page
every few days. Here is one of their descriptions:

"W32/IRCbot.worm! is a medium risk worm for home users. You can be
infected simply by going online. Once infected, your computer may
restart continuously."

If you follow a McAfee link to a more detailed description of the worm,
you find in part:

"This threat scans for MS05-039 exploitable systems. When a vulnerable
system is found, it uses a buffer overflow to write the worm file to
that machine via a TFTP upload on port 8594. Blocking this port via
McAfee Desktop Firewall or McAfee Personal Firewall will prevent
infection even if the buffer overflow is not prevented."

Few of us have the time or interest to keep up with the details of the
several new important bugs discovered nearly every week. If there were
no more bugs, likely hundreds of people working at security companies
and Microsoft would be looking for new jobs. I have both my security
programs and Microsoft update set to update automatically so that I do
not have to check for new updates very often. You also need to pay
attention to the security program icon on your desktop. For example
mine is red if it is working and black if it is not.

ActiveX does not run in my Mozilla/Firefox, neither in Linux nor in
Windows. And on Linux, ActiveX does not run in any other UA, too.

Probably you mean security leaks exploited to infect computers that have
merely established an Internet connection, which is not the same.
Especially if you have a Windows OS, you must take all Microsoft critical
updates, have good virus protection,
The (sad) truth is that no virus protection can be good enough. Vendors of
anti-virus software cannot be faster than the thousands of malicious people
writing malicious software. You could be the one that discovers your
system being infected with the brand-new virus nobody knows about. Of
course vendors of anti-virus software do not tell you this, they want to
make money. Your money.
have a good firewall,

Utter nonsense. A firewall, may it be just snake-oil software ("desktop
firewall") or a real one (that is, a security concept including a network
packet filter), cannot protect you from yourself, allowing your system to
be compromised by running inherently insecure software and clicking on
everything that cannot fight back. Of course vendors of so-called "desktop
firewalls" do not tell you this, they want to make (your) money one way
(you buying their snake oil and feeling protected while you are not at all)
or the other (you providing them with potentially valuable information
without knowing it).

<URL:http://www.interhack.net/pubs/fwfaq/>

Again, what is the right thing to do is not to use inherently insecure
software (that includes inherently insecure operating systems), or
configure the system as secure as possible if the former is not
possible, and to develop a common sense for secure use of computers.

You can of course reduce your chances for infection by using one of the
lesser used OSs rather than Windows. Many of these are more difficult
to hack than the XP, but also the XP is a favorite target of hackers
because they can infect a larger number of of computers that way.
Unfortunately many of us must use a Windows OS, because many important
media and other programs do not have versions for other OSs. If you are
working with professional media programs, fortunately many of these
have Mac as well as Windows versions. Many of the media professionals
love Mac for their work. Macs have been hacked, but not nearly as much
as Windows.

I should mention that ActiveX usually is found only on Microsoft OSs,
browsers, and their close relatives such as MSN9. However there have
been downloads available for Firefox, Mozilla, and Netscape to support
ActiveX for the Windows Media Player only. The reason is that some
write media pages using only ActiveX support. This limited use of
ActiveX for the WMP only is likely much safer than full ActiveX
support. Opera seems to have found some indirect way to support media
for the WMP written using ActiveX code only. I have no idea how they do
this, but it is extremely unlikely that they use ActiveX for anything
on their browser. Of course, if one wishes to live dangerously, you can
locate full ActiveX plugins for many browsers.

I should add that spyware, malware, scumware, or whatever you choose to
call it has become a big problem. If you have a Windows OS, you can
download a spyware protection program for free.But they check your
computer to make sure you have an official Windows OS, and if not you
get no download.

Of course it still pays to be careful. Stay away from doubtful sites,
use an email service or agent that scans for problems, etc. I have
never used Outlook/Outlook Express. I use the Yahoo mail service
provided by my isp SBC/Yahoo DSL, but free Yahoo mail is available to
everyone. They will not open any attachment for you until it is scanned
for a virus. I open all of my domain mail at Yahoo mail as pop mail. As
in most things in life, nothing is certain. You could be the first on
the block to get a new bug before updates for it are available in
protection programs. However, especially if you use a Windows OS, you
can greatly reduce the odds if you have good protection programs as
well as use caution about what you view or open.

Even on a Windows OS browser, you likely can reduce your chances for
infection by using a browser other than IE when online. I usually use
Opera or Firefox, but you still have to use IE to view some sites
properly. I have Opera set for very high security and use it for
questionable sites. It asks for you to accept or refuse all cookies of
any type a site my try to plant on your computer. I have seen sites for
which you have to refuse cookies 20 times, and some sites will not let
you in without cookies.

Trivial to do actually even now without a pop up blocker and considering
that even IE comes with one by default (enabled no less) its not a
concern anymore. But for kicks and giggles, you can disable yours and
execute this script for fun:

<script type="text/javascript">
while (1){window.open('www.netscape.com')}
</script>

And anybody that surfs the web without a pop up blocker deserves what
that script snippet will do.

It also wrote "Crashing" in the status bar, and the computer crashed.
Repeatedly opening new windows causes that to happen......
This is a very simple bug by today's standards.
It wasn't a "bug" then and it's not a "bug" now. It was an exploitation
of user's ignorance about pop ups and the lack of a decent pop up blocker.
Rather than playing child-like pranks such as the above, the modern
hacker may not want you to know your computer is infected.
And I will ask *again*. Post some JavaScript code that will "infect" my
computer. I want to see it.

He or she may be more interested in making your computer a zombie to send out

Again, post some code. And, post code that will cause *my* PC to
repeatedly send out emails. Go on, try it.

Also give some detail on how "just sign[ing] onto
the web" will cause infection.
McAfee features a different bug on their security center home page
every few days. Here is one of their descriptions:

Anybody dumb enough to buy into McAfee's marketing hype deserves to pay
for the product that McAfee is selling. Do you actually expect to open a
website that sells an anti-virus product and not read how you should
have it?
"W32/IRCbot.worm! is a medium risk worm for home users. You can be
infected simply by going online. Once infected, your computer may
restart continuously."
Thats ignorance on the users part.
If you follow a McAfee link to a more detailed description of the worm,
you find in part:

"This threat scans for MS05-039 exploitable systems. When a vulnerable
system is found, it uses a buffer overflow to write the worm file to
that machine via a TFTP upload on port 8594. Blocking this port via
McAfee Desktop Firewall or McAfee Personal Firewall will prevent
infection even if the buffer overflow is not prevented."
The only thing being exploited there is peoples fear. And the ones doing
the exploiting are McAfee.
Few of us have the time or interest to keep up with the details of the
several new important bugs discovered nearly every week.
And some of us, myself being the first one to say so, don't care about
the details of new "important bugs" discovered. When MS updates the OS,
I update it. I have no need to try to track it myself.
If there were no more bugs, likely hundreds of people working at
security companies and Microsoft would be looking for new jobs.
And as long as that stays true, there will always be people trying to
keep a job by telling you to buy the product they are selling.
I have both my security programs and Microsoft update set to update
automatically so that I do not have to check for new updates very often.
Smart move.
You also need to pay attention to the security program icon on your desktop.
What "security icon"? You mean the one I told the day I got WinXP to
shut up and let me handle my own PC? I disabled that piece of crap long ago.
For example mine is red if it is working and black if it is not.

Then it should stay black all the time......

Very early. What does that have to do with how Javascript "will cause
serious problems"?

A virus that crashes a computer is a serious problem to me, but
everyone may have a different threshold for what is serious. Of course
this virus is seldom met anymore. I gave it as an example of a pure JS
virus rather than a modern one that often mixes several types of code.
However someone at a software company put it in a code for a free html
editor, apparently a former employee, as a prank. The software company
did not bother to remove it for years. Thus many people had their
antivirus program detect it when they downloaded the program. I believe
the virus was put in the program in a form that would do no harm,
except set off virus detection programs. This subject kept coming up in
NGs for many years.

Many modern viruses and worms use a combination of various codes, of
which javascript often is a part, and the problems caused by some of
these can be quite severe. You can find a huge number of references to
these on Google at
http://www.google.com/search?as_q=ja...s=&safe=images

. If this very long URL fails, just use advanced search, require virus
or worm, and require javascript. Javascript is very much alive and well
in many recent bugs.

No, I do not work for a security or anti-virus company. You are
entitled to your opinion about what is true. However I suspect that
many would argue with this conclusion, especially for those who use
Windows XP without protective programs. I think that even Microsoft
will suggest protective programs on computers that use Windows OSs, and
they are not a big player in the security market - at least not yet.
The XP does provide a one way firewall, and I doubt if Microsoft went
to the expense to put this in if they did not think it was needed -at
least for average computer users. If you want a 2 way firewall, you
have to obtain it elsewhere. Or if you are on broadband and use a
router with firewall protection, as often is the case, the issue
concerning a firewall on the computer itself becomes moot.
The best defense against being infected? Knowledge. Knowledge of how
your computer works (at least a basic understanding) and a basic
knowledge of how the web works. Now you can be safe.
The world is seldom ideal, and people who post to this and other
technical NGs likely know far more about computers than the average
computer owner. Also several family members may use the same computer,
and some may not know much about it. My impression is that many PC
owners now just consider it as another household appliance, expect it
to work well out of the box, and are not going to be bothered with much
upkeep. At least in the US, many computers are replaced when they
become very slow because of infection with multiple viruses and worms
or other technical issues, even though they often could be easily fixed
if the owner did just a little research, or perhaps asked a neighbor
teen computer geek to take a look.They could care less about how the
computer works. As long as it does email, allows them to use their bank
etc, and allows them to order goods, they are happy. Some, especially
those who live alone, are into chat.
Even my mother knows how to keep from getting her computer infected. She
has no firewall and no anti-virus program but she has the Knowledge to
know how to stay safe.

I have no idea what OS and browser your mother's computer uses. I have
know people who have an older Mac who have no protection and are not
especially careful, but who have never had problems, because there are
far fewer viruses and worms aimed at these older Macs. However you
mother has a son who is quite knowledgable about computers :-). For all
I know, your mother could be a computer engineer. However not all
mothers are especially careful when using a computer or have sons who
are knowledgable. Of course some mothers think mother-knows-best and
what you say to them goes in one ear and out the other.

Such questions are better to be posted/answered at astalavista.com and
so.
Briefly and plainly: JavaScript by itself can do *nothing* to your
computer because it doesn't provide access to any system resources. The
best achievement within JavaScript itself would be some
systemwise-harmless nastiness like:
while (true) {
alert("I'm cool hacker Joe!");
} // :-)

JavaScript though can be used to unitiate host objects with system
access (DOM / ActiveX / XPConnect). This aspect is really out of
JavaScript responsability and depends of how wise the relevant object
have been written. For example IE 6.0 has a by-design hole in one
module allowing to infect the system in seconds even with *any
anti-virus software installed*. This hole was finally fixed only in IE
on XP SP2 or higher. On any lower versions your only protection is do
not go to any suspitious places. And this exploit also doesn't depend
on JScript enabled or not - only on <object> activation.

Does JavaScript / JScript disabled gurantees safe browsing? Not at all.
If say you're using Windows higher then Win98, you are vulnerable to
port attacks and you have to have personal firewall installed (or sit
behind a corporate one). Otherwise you even do not need to launch your
prowser - Internet connection itself is enough to be infected if your
computer is found by port spiders.

Does JavaScript / JScript disabled removes some possible
vulnerabilities? Yes it does, but only smaller part of them.

1) Antivirus with regular update subscription
2) Firewall
3) All producer recommended updates for your OS
4) Latest producer recommended version of your preffered browser
5) A regular cautioness with files received from the Web

There are some money and efforts required to invest from the *customer
side* and it is much more (as you can see) than click some "disabled"
button.

No, I do not work for a security or anti-virus company. You are
entitled to your opinion about what is true. However I suspect that
many would argue with this conclusion, especially for those who use
Windows XP without protective programs. I think that even Microsoft
will suggest protective programs on computers that use Windows OSs, and
they are not a big player in the security market - at least not yet.

You may be right, but see
http://www.microsoft.com/windowsxp/u...2_wfintro.mspx
for details about the Microsoft firewall included with the XP, post
sp2. It makes mention that there firewall can block incoming attempts
to connect to ports, etc. It does not mention that it will block
outgoing attempts by your computer to connect to somewhere, which is
the second leg of a 2 way firewall. On the 2 way firewall I use, I can
even block a browser so it can not get out. This feature is useful for
a few programs that do not need to be on the web when you use them. A
few programs report back various things that some might consider an
invasion of privacy. I do not use the Microsoft firewall, but rather
another one that is 2 way, keeps detailed logs of all attempts to
connect, and allows you to easily trace the source of attempts. Such
attempts to find open ports happen all of the time from all over the
world, but especially from a few far Eastern countries.

It is interesting that Microsoft, in the reference given, also suggests
use of anti-virus software when using the XP and gives a link to
considerations for selection of such software.

Again, you could be right. Microsoft has so many updates for the XP
that it is difficult to keep track of just what each update does. It
would not surprise me if they made modifications in their firewall, and
since I use another firewall, I would never notice such a possible
change.

This thread has grown into a rather long, now off topic, monster. This
sometimes happens over weekends when there are not many questions
concerning script to answer. Hopefully there will be more posts more
directly concerned with script soon.

Rubbish. They're false positives, or your set-up is not "authentic".

Not necessarily rubbish. I had a similar experience, but it didn't take my
NOD32 A/V program to discover I'd been invaded.

Turns out that after installing XP I had my machine connected to DSL. When
IE installed, it set its 'home page' to MSN.com. Shortly after connecting
to MSN, the shit hit the fan. Machine started to reboot, etc. An AV scan
showed about 4 or 5 viruses had invaded my new machine.

The Windows Firewall *does* block outgoing traffic. It frequently asks
if an application should be permitted access to the internet.

You allowed IE, out into the unknown with inadequate security. That's
how you got infected - you *let* it happen.

As was pointed out, that is a flaw on *your* part. You are the one that
allowed it out without checking it first.

You can not put anything on my PC without me, directly or indirectly,
allowing it. And if you allow it, you reap what you sow.

In fact, depending on the security settings you choose, you do
sometimes get a warning message when online if the site you go to tries
to get some information sent to it or elsewhere. I also have this
happen to me when I am on the web using IE6. However, my Windows
firewall is completely disabled by another, in my opinion better, 2 way
firewall I use, and a check of Windows settings confirms that the
Windows XP firewall is indeed disabled. Thus this has nothing to do
with the Windows firewall and everything to do with the security
selection features that were greatly improved with sp2. What my 2 way
firewall does is display every application you have on your computer.
Each application may be completely blocked from the web, allow
outgoing, or be unblocked. If you change the security settings, when on
IE6, to the lowest possible (not recommended), you seldom get any kind
of message. If you set for maximum security you can not get into many
safe sites such as my bank, etc. Security settings are somewhat
different for various browsers. I keep Opera set at very high security
for the most doubtful sites and Firefox a little less secure for
trusted sites. On broadband, it is no problem having several browsers
in use at once, and I often have the SBC/Yahoo DSL(IE6 relative),
Firefox, and Opera all connected to the web when I am testing pages on
different browsers. Thus you often notice differences in security
warning response for different browsers when you are viewing the same
page with 3 browsers.

In the last 15 minutes, over 20 attempts to get into many different
ports have been rejected and recorded in my firewall log. Tonight many
can be traced to China. Many of these likely are attempting to find an
open port, get in, and take advantage of a worm or virus that they hope
has been planted on the computer. I take part in a program that reports
all of these attempts to a data base that is used to help improve web
security. Some ISPs likely are targeted much more than others. The
large broadband ISPs in the US seem to be favorite targets. A computer
that always is connected to broadband is likely much more useful to
many hackers than one that is online only now and then and connected on
dialup.

But back to javascript, I would love to see a page using a script for
which you are most proud, since you seem to have very strong opinions
about how to best write scripts.

By the way, I do not really care about subjective adjectives, good or
bad, that anyone may use on the web. Such usually are not allowed in a
proper technical journal owned by an important scientific or
engineering society where papers are properly peer reviewed and
objective statements are required. I can not get very excited in an
emotional way, pro or con, about anything I read in an open NG. You
seldom know anything about the qualifications of the person expressing
an opinion.You could have the Queen of England(unlikely, but there is a
royal site), you could have a technician at a famous university who
knows little about computing and perhaps dissects frogs for a
researcher, or you may have someone who knows nearly nothing about
computing at all. And I doubt if skills in html, javascript, or C++ are
likely to be considered profound enough to win a Nobel prize.

So farewell to this much too long, off topic thread. Was there a full
moon this weekend? It has been too cloudy here for me to notice.

<snip>

The only qualification that matters on a technical newsgroup with a
specific subject is how much an individual knows about the group's
subject, and that is relatively easy to determine from their
interactions with the group. It doesn't matter that anyone can post
anything they like to any group because if their writing is perceived as
questionable it will be questioned. The people who understand the
subject will be able to explain and justify their statements, the people
who are learning will be able to explain their understanding (and be in
a position to learn from the comments they receive in response), and the
people who would rather pretend that they know more than they do (often
as much to themselves as to others) will bluster and vacillate and
expose the truth in the process.

Two or three months reading this (relativity heavily trafficked)
newsgroup should identify most of the people who are worth listening to,
and the utterly worthless usually give themselves away quite quickly,
with the many in-between often rapidly migrating towards the more
informed end of the spectrum, if they actively participate. Newsgroups
may seem overly critical but understanding evolves quickly in a hostile
environment.

Richard.
