Book Description
Everything you need to learn JavaScript from Scratch!

Packed with full-color examples, Simply JavaScript is a step-by-step introduction to programming in JavaScript the right way. Learn how easy it is to use JavaScript to solve real-world problems, build smarter forms, track user events (such as mouse clicks and key strokes), and design eye-catching animations. Then move into more powerful techniques using the DOM and Ajax.

* Learn JavaScript's built-in functions, methods, and properties.
* Easily integrate JavaScript in your web site.
* Use JavaScript to validate form entries and interact with your users.
* Understand how to respond to user events.
* Create animations that bring your web site to life.
* Start programming using the DOM and Ajax.

Unlike other JavaScript books, modern best practices such as progressive enhancement, accessibility and unobtrusive scripting are used from the very beginning. All the code in the book is also cross-browser compatible and downloadable for free, so you can get started instantly!

[Wrox] Beginning JavaScript (2007)
12.7 MB

Book Description
Suitable for learning basic programming for Web browsers, Beginning JavaScript is a patient, introductory tutorial on writing scripts successfully. It teaches you how to create client-side scripts (including full coverage of fundamentals like variables and flow control, plus plenty of screen shots.)

JavaScript is a good way to learn programming. It's powerful, of course, but the book takes small steps, using scripts that work with string and time data first, and then moving to manipulating browser objects like forms and windows. A running case study for a trivia game helps anchor the steps with a practical (and fun) example. There are plenty of tips on debugging your scripts (including how to use the M!crosoft Script Debugger tool), and each section includes sample questions. (The book also offers extensive answers in over 80 pages at the end of the book.)

There's plenty of material on the differences between Internet Explorer and Netscape, especially when it comes to Dynamic HTML (DHTML). Coverage of the Document Object Model (DOM) for browsers helps bring the text up to date on some of the latest standards in Web browsers (including the new Netscape 6).

While the focus of Beginning JavaScript clearly is on the client, later sections turn to server-side ASP development (in which the sample trivia game is enhanced with ASPs written in JavaScript using ADO and M!crosoft Access.) Reference sections on JavaScript and the browser object model for Internet Explorer and Netscape (through version 4.x) round out the material.

In all, with its approachable style and clearly rendered code examples, Beginning JavaScript makes for a worthwhile first book of programming for today's browsers. Even if you haven't programmed before, this text can give you the tools you need to bring your static Web pages to life.

Book Description
As web browsers have become more capable and standards compliant, JavaScript has grown in prominence. JavaScript lets designers add sparkle and life to web pages, while more complex JavaScript has led to the rise of Ajax -- the latest rage in web development that allows developers to create powerful and more responsive applications in the browser window.

Learning JavaScript introduces this powerful scripting language to web designers and developers in easy-to-understand terms. Using the latest examples from modern browser development practices, this book teaches you how to integrate the language with the browser environment, and how to practice proper coding techniques for standards-compliant web sites. By the end of the book, you'll be able to use all of the JavaScript language and many of the object models provided by web browsers, and you'll even be able to create a basic Ajax application.

screen 4.0.3 loacal Authentication Bypass

Author: Rembrandt
Affected Software: screen <= 4.0.3
Affected OS : OpenBSD (any up to current (wich will become oBSD 4.4))
Type: Local
Type: Authentication Bypass

screen is vulnerable to a authentication bypass which allows local attackers
to gain system access in case screen was locked with a password.

It has been tested on OpenBSD + screen 4.0.3 on x86/amd64.
But during the nature of the behavior of screen and OpenBSD it should be
architecture/version indipendent for now.

How to check this?

Lock screen using ctrl+x
Choose a Password
Confirm the Password

Screen asks for a Password to unlock the screen.
Just press ctrl+c and if you like screen-x to reattach the screen-session.

Example:

$ testscreen
/bin/ksh: testscreen: not found
$
Key:
Again:
Screen used by rembrandt .
Password:
$ screen -x
There are several suitable screens on:
29602.ttyC0.raven (Attached)
25144.ttyC1.raven (Detached)
Type "screen [-d] -r [pid.]tty.host" to resume one of them.
$ screen -x 25144
$ testscreen
/bin/ksh: testscreen: not found
$

Because of the nature of a locked screen you wont be able to lock your shell.
screen will never ask you for a password.

Of course this works also if you get access to a SSH wich has a locked
screen running. So in case you have locked your screen session wich contains
a open SSH session to a host where you also have a locked screen session
you might have no password protection at all in case all systems are OpenBSD.
That is just another example. Importent for you should be the combination of
screen and OpenBSD.

Do not claim it does not work because you just tested this against the latest
Linux/Solaris/Whatever.

It is known to work and I mentioned the OS.
Still it is known that it worked against some scarry Linux distributions
wich are not realy common.

All security websites wich do report this is a fake may consider to update their
reports except of simply claiming wrong things.

* OS : Windows ALL
* Crew : Dreatica-FXP
* ----------------------------------------
* Details : Obtain the overflow and crash the application is peace a cake job.
* To make a wroking code execution here is a hell. First we can see that
* the username before overflow the buffer pass through some functions,
* that changes and restrict some useful chars. Firstly the beffer gets
* lowered so the overflow should not contain upper chars :( . So i decided
* to use some encoders for the payload like nonupper and non alpha from MSF.
* The nonupper use the `@` (0x40) char which the app doesn't eat at all.
* The nonalpha encoder in decoder code and the generated body contained
* always the 0xC0, 0xC1, 0x80, 0x81 which were translated to 0xE0, 0xE1,
* 0x90, 0x91. Don't know, may be this chars translation was due to my russian locale.
* After few days of work i have comed with the required bindshell which bypass
* all restricted chars and executes. Thx to skylined, for his alpha tool.
* Bad chars : 0x00 0x40 0x41 0x42 0x43 0x44 0x45 0x46 0x47 0x48 0x49 0x4A 0x4B 0x4C 0x4D 0x4E

Exploiting Software Vulnerabilities - A case study

Optimized Blind SQL Injection

Blind sql injection is a technique that let hackers retrieve database data through a sql injection that doesn't give out useful information through web application errors.

Security by obscurity is not security though. Sqlmap and Absinthe demonstrate this clearly. They are capable of getting you the whole database even if no error is shown when user inputs characters meant to
trigger an sql error.

So how is it possible to still get database data without triggering web application errors?
These tools basically work on a true/false base. They provide the web app with input known to be faulty to trigger a FALSE case and input known to be working to trigger a TRUE case.

Using a TRUE/FALSE condition a loop through the charset is undertaken to recover a string in the database one character at a time. Usually the SUBSTRING/CONCAT sql commands are used to match a correct guess with the TRUE case.

The problem with this approach is the time it takes to retrieve data from the database.
Most of the tools for blind sql injection are not optimized.
Recently I came across with a nice research from Secforce.

They have written a quick tool to optimize the task of dumping a database through a blind sql injection.

The tool, written in python is basically a shell.
You provide parameters like vulnerable web page and then it will retrieve the desired portion of database (table names, column names or full data), nothing different from all the other sql injection tools.

What makes this tool better than the others (for blind sqli) is its speed thanks to the optimizations used to find characters.
You can read more about the implemented optimizations here.
From a test I personally undergone I noticed that sqlmap is the tool that is best (together with secforce blind sql injection tool) at dumping data through blind sql injection.

Here's the dump from the console of an injection process using sqlmap:

remote DBMS: Microsoft SQL Server

The process above is discussed in the paper released by secforce.
Sqlmap has retrieved the database banner/version in approx. 60 seconds.

Blind SQL Injection shell has done in 80 seconds due to the fact that it retrieves all the chars one by one thus being able to retrieve any kind of banner with 100% precision while sqlmap requires the matching of few chars to match it with default banners.

On-Site Security Assessment

Internal on-site penetration testing gives the business the assurance it needs to conduct safely on the internet and with business partners.

Internal assessments use a similar methodology to an external assessment, however the engagement will occur from within the WAN at each logical management zone, physical segment or simply attached to the DMZ.

To attach to an internal network requires a significant depth of knowledge in many areas. These areas are not limited to Policy, Architecture, Implementation and Auditing across multiple business units, operating systems and devices. Pure Hacking has all of these skill sets.

With most internal assessments, Pure Hacking has discovered for its clients significant business risks that would cease business operations within hours. 20% of the remedial work for these clients gives them 80% of their security effectiveness and as such, the advice guards against network security attacks. The advice is independent of any vendor, and is often accomplished through our clients existing partners.

From an internal assessment, our clients gain more business value if part or all of their operations are outsourced. The recommendations given will be independent of any supplier or vendor, and as such, the current supplier can remedy the situation without further cost. The net results - our clients are safe and get a greater R.O.I from their outsourced partners and the outsourced partners gain specialized security intellectual property.

External Penetration Testing

What is an External Penetration Test?

This test focuses on

* server penetration testing
* router penetration testing
* firewall penetration testing
* operating system installation and maintenance.

The penetration test may be performed with non or full disclosure of the environment in question.
The engagement would start with publicly accessible information about the client, followed by network enumeration.
Network enumeration allows Pure Hacking to target hosts, and specific network security attacks. Pure Hacking would then assess the open ports, services and specific security vulnerabilities, and use that information to gain a toehold into the environment. After a toehold is established, escalation of privilege occurs until the external environment is controlled.

What do you get at the end of the engagement?

Depending on the scope of work, a typical report would include any or all of these components (reference: OSSTMM):

Network Security
Network Surveying
Port Scanning
System Identification
Services Identification
Vulnerability Research & Verification
Application Testing & Code Review
Router Testing
Firewall Testing
Intrusion Detection System Testing
Trusted Systems Testing
Password Cracking
Denial of Service Testing
Containment Measures Testing

Social Engineering
Request Testing
Guided Suggestion Testing
Trust Testing

Wireless Security
Wireless Networks Testing
Cordless Communications Testing
Privacy Review
Infrared Systems Testing

Communications Security
PBX Testing
Voicemail Testing
FAX review
Modem Testing

Physical Security
Access Controls Testing
Perimeter Review
Monitoring Review
Alarm Response Testing
Location Review
Environment Review

A Virus for MS-DOS Systems.
Copy-ya-right (c) June 29, 1990 by PCM2

GENERAL SUMMARY
~~~~~~~~~~~~~~~

LEPROSY is a virus which can influence PC and PC clone
systems running MS-DOS or PC-DOS version 2.0 or later. It may
be characterized as an overwriting, non-resident .COM and .EXE
infecting virus, similar in operation to the AIDS Virus by
Doctor Dissector and CPI; in fact, the AIDS Virus was actually
the inspiration for this program, though Leprosy is in no way a
re-write or mod of the AIDS Virus, it is an entirely new
program.

The way both Leprosy and the AIDS Virus (and Number One,
the ancestor of AIDS) work is fairly simple. Upon executing the
virus program, the virus runs a search for executable files
which it can affect. It does this by doing a general scan for
all files with a .COM or .EXE extension, then, having found such
a file, it loads in part of that file's code to compare it with
the virus' own code, to make sure the file found hasn't already
been infected. If it hasn't, the virus proceeds to write itself
OVER the code of the executable file found. The executable file
now ceases to perform its original function. When the
unsuspecing user runs the file, he will instead be running
another copy of the virus, which will seek out another
executable file to infect, and so on. The executable files
which are infected by the virus in this manner are permanently
destroyed. While this is a primitive way to spread a virus, it
is actually pretty effective, if you consider that by the time
the user discovers a file which has been infected by the virus,
it has already gone and zapped one or more other files, and by
the time the user finds those files, they will have infected a
few more, and on until the user figures out some way to detect
and eradicate all the infected files.

While Leprosy is similar in operation to the AIDS Virus, it
presents several important advantages over AIDS:

1. CARRIERS: The AIDS Virus will only infect .COM files.
Leprosy is not limited in this way; it will infect both .COM
files and the more common .EXE files, going for .EXE files first.

2. FILE SIZE: The AIDS Virus is written in Pascal, and is about
13K in size. Considering that any file that is infected which
was originally smaller than the virus itself will expand to the

- 1 -

size of the virus when it is infected, and that many .COM files
will be smaller than 13K, quite often a file will show a
noticeable change in size when infected by the AIDS Virus.
Leprosy is only a mere 666 bytes in size; therefore, changes in
file size will be much less frequent, and the disk access time
it takes to infect a new file will be considerably shorter than
when using the AIDS Virus.

3. DUMBSHIT FACTOR: When the AIDS Virus infects a file or fails
to find any non-infected files, it just sits there or hangs up
the system. Leprosy takes a more subtle approach, however.
When Leprosy has infected some files successfully, it prints out
the message "Program too big to fit in memory". This way,
dumbshits might think there is something screwy with their RAMs
or TSRs, and may end up running the same virus-infected file one
or more times before they get a clue.

4. CONCEALMENT: To find out if a file has been infected by the
AIDS Virus, all you need to do is run a hex editor on the file
and look for the full screen reading "AIDS" in the code. Once
again, Leprosy makes it more difficult on the dumbshit user.
All the strings Leprosy outputs to the screen are encrypted in a
simple way, enough to make it impossible to quickly spot
suspicious phrases when running a hex editor on an infected
file. What is more, Leprosy will not change the time/date stamp
on the file when it infects it, unlike AIDS.

5. COMMUNICABILITY: When the AIDS Virus fails to locate any
non-infected .COM file in the current directory, it can no
longer spread itself. The only way an AIDS Virus can spread
from one directory to another is to somehow make it into one of
the directories in the current PATH, and be called by the user
from a different directory. Leprosy gives itself one more
shot. When it fails to find any more non-infected files in the
current directory, it will step back into the parent directory,
and try to find some files again there. While when the virus
exits the current directory will have changed when Leprosy does
this, hopefully the dumbshit won't catch on. The payback is
that Leprosy might eventually creep up to the root directory and
infect COMMAND.COM, and then the user will be fucked over.

6. RATE OF TRANSMISSION: The AIDS Virus will only infect one
file at a time. Leprosy will infect up to four files each time
it is run.

SETTING UP LEPROSY ON A SYSTEM
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To install Leprosy onto an un-infected system, all you need
do is run the provided file, LEPROSY.COM, somewhere on that
system, preferably somewhere where it will have access to a lot
of commonly used executables. Alternately, you could infect
some program with an impressive-looking file length and

- 2 -

documentation and send it to someone as a Trojan Horse type
program. Just make sure it gets run.

COMPILING LEPROSY
~~~~~~~~~~~~~~~~~

To assemble the Leprosy .COM file, you will need Turbo C
2.0 and Turbo Assembler. MASM might work, just as long as the
executable file turns out the appropriate length. If the .COM
file doesn't come out to exactly 666 bytes long, then it might
not work properly. C compilers other than Turbo C will probably
not work, since the program makes extensive use of inline
assembler, but versions other than 2.0 will probably be okay.
Just remember -- watch the file length.

The easiest way to re-create Leprosy is to just run MAKE,
and the provided makefile will handle the rest. If you are
compiling it by hand, you should use this makefile as your
guidelines. An important note is that you should not link the
program with the standard Turbo C startup code for the Tiny
memory model; instead, always link it with the provided
alternate startup code. This file, C0T.ASM, is a startup
sequence which gets rid of code to gather command line arguments
and the like, allowing for programs which are essentially as
small as their assembly language counterparts. Just remember,
keep an eye on the executable file size.

WAYS TO SPOT THE VIRUS
~~~~~~~~~~~~~~~~~~~~~~

There are several ways to notice the Leprosy virus on your
system. If small .COM files are increasing in length to 666
bytes, that's your first hint. 666 bytes isn't a very likely
file length, but it's funny, so I'm keeping it that way. Also,
if the current directory changes when you run a program, or you
notice strange "Program too big to fit in memory" errors, that
should tip you off too. Leprosy can also be detected by CRC
checking programs, because it directly modifies the contents of
the files it infects. What is more, Leprosy causes a
distinctive drive noise, sort of a "blickablickablickablicka" on
my hard drive, because it is opening, reading from, writing to,
and closing a number of files very quickly.

ACKNOWLEDGEMENTS
~~~~~~~~~~~~~~~~

I'd like to thank some of the pirate boards in the (415)
area code -- they know who they are.

What is more, I'd like to say that I used the December 26,
1989 issue of PC Magazine, and the book "The NEW Peter Norton
Programmer's Guide to the IBM PC and PS/2" in the process of

- 3 -

writing the Leprosy program. I just thought I'd mention that,
since it kind of makes me laugh to wonder what Peter Norton and
PC Magazine would think if they knew they were partly
responsible for the creation of a virus. HAHA!

Yours truly,
PCM2

P.S. BTW, if Leprosy fails to find any .EXE or .COM files that
aren't infected, but it locates more than 6 executable
files that are already infected with Leprosy, it displays a
message indicating that the system has been infected with
Leprosy, and wishes the user luck. If it can't find any
new files to infect, and only finds 6 or less infected
files during its entire run, it just prints out the fake
"Program too big to fit in memory" message again.
