Cyber security is one of the major concern of the people who are trying to protect the data from the intruders who are trying to hack the system and who are trying to steal the data.
There are different kinds of skills that a cyber security expert must have. Today we’re going to talk about a few important skills that can help you succeed in cyber security.
Many cyber security agencies take action when they are in trouble and when the intruder has already hacked their system. This is the worst thing for someone to handle because they are in fear of losing the data.
Once you learn the way of detecting the thread through which someone entered the system, you’ll become a successful cyber security expert. You’ll be able to become a top-rated and successful cyber security expert if you could become a master in this skill.
At the time of keeping the system safe and secure, you should know how to develop the software and how you will be able to protect the data of a client effectively. This should be your first concern at the time of working on any project.
And the client will definitely be pleased enough to refer you to his friends as well that are in his business circle. It is a very expensive step for a company but once they took this difficult step their company will be protected from all the intruders and they’ll be able to produce much better results.
If you want to achieve a higher rank, then you should find some new ways of finding the risk and getting rid of it. You need to discover something new and advance to show that you have outstanding skills.
You can impress your client with your tips and tricks. If you are showing them how you can go out of the box and how you can protect the system then, of course, this is going to be your success point.
MALWARE INSIDE ORGANIZATION
This is not important that you have to take care of the external links and external files. If you want to be a smart employee then you should take care of the malware inside the organization.
People inside the company may try to enter the files into the system which are already infected and can harm your system. You will see how the system will be hacked just by using the infected file. You have to keep an eye everywhere.

This article is a ‘quick-n-dirty’ introduction to the AT&T assembly language syntax, as implemented in the GNU Assembler as(1). For the first timer the AT&T syntax may seem a bit confusing, but if you have any kind of assembly language programming background, it’s easy to catch up once you have a few rules in mind. I assume you have some familiarity to what is commonly referred to as the INTEL-syntax for assembly language instructions, as described in the x86 manuals. Due to its simplicity, I use the NASM (Netwide Assembler) variant of the INTEL-syntax to cite differences between the formats.
The GNU assembler is a part of the GNU Binary Utilities (binutils), and a back-end to the GNU Compiler Collection. Although as is not the preferred assembler for writing reasonably big assembler programs, its a vital part of contemporary Unix-like systems, especially for kernel-level hacking. Often criticised for its cryptic AT&T-style syntax, it is argued that as was written with an emphasis on being used as a back-end to GCC, with little concern for “developer-friendliness”. If you are an assembler programmer hailing from an INTEL-Syntax background, you’ll experience a degree of stifling with regard to code-readability and code-generation. Nevertheless, it must be stated that, many operating systems’ code-base depend on as as the assembler for generating low-level code.
The Basic Format
The structure of a program in AT&T-syntax is similar to any other assembler-syntax, consisting of a series of directives, labels, instructions – composed of a mnemonic followed by a maximum of three operands. The most prominent difference in the AT&T-syntax stems from the ordering of the operands.
For example, the general format of a basic data movement instruction in INTEL-syntax is,
mnemonic destination, source
whereas, in the case of AT&T, the general format is
mnemonic source, destination
To some (including myself), this format is more intuitive. The following sections describe the types of operands to AT&T assembler instructions for the x86 architecture.
All register names of the IA-32 architecture must be prefixed by a ‘%’ sign, eg. %al,%bx, %ds, %cr0 etc.
mov %ax, %bx
The above example is the mov instruction that moves the value from the 16-bit register AX to 16-bit register BX.
All literal values must be prefixed by a ‘$’ sign. For example,
mov $100, %bx mov $A, %al
The first instruction moves the the value 100 into the register AX and the second one moves the numerical value of the ascii A into the AL register. To make things clearer, note that the below example is not a valid instruction,
mov %bx, $100
as it just tries to move the value in register bx to a literal value. It just doesn’t make any sense.
In the AT&T Syntax, memory is referenced in the following way,
parts of which can be omitted depending on the address you want.
Please note that the offsets and the scale should not be prefixed by ‘$’. A few more examples with their equivalent NASM-syntax, should make things clearer,
GAS memory operand NASM memory operand ------------------ ------------------- 100  %es:100 [es:100] (%eax) [eax] (%eax,%ebx) [eax+ebx] (%ecx,%ebx,2) [ecx+ebx*2] (,%ebx,2) [ebx*2] -10(%eax) [eax-10] %ds:-10(%ebp) [ds:ebp-10]
mov %ax, 100 mov %eax, -100(%eax)
The first instruction moves the value in register AX into offset 100 of the data segment register (by default), and the second one moves the value in eax register to [eax-100].
At times, especially when moving literal values to memory, it becomes neccessary to specify the size-of-transfer or the operand-size. For example the instruction,
mov $10, 100
only specfies that the value 10 is to be moved to the memory offset 100, but not the transfer size. In NASM this is done by adding the casting keyword byte/word/dword etc. to any of the operands. In AT&T syntax, this is done by adding a suffix – b/w/l – to the instruction. For example,
movb $10, %es:(%eax)
moves a byte value 10 to the memory location [ea:eax], whereas,
movl $10, %es:(%eax)
moves a long value (dword) 10 to the same place.
A few more examples,
movl $100, %ebx pushl %eax popw %ax
Control Transfer Instructions
The jmp, call, ret, etc., instructions transfer the control from one part of a program to another. They can be classified as control transfers to the same code segment (near) or to different code segments (far). The possible types of branch addressing are – relative offset (label), register, memory operand, and segment-offset pointers.
Relative offsets, are specified using labels, as shown below.
label1: . . jmp label1
Branch addressing using registers or memory operands must be prefixed by a ‘*’. To specify a “far” control tranfers, a ‘l’ must be prefixed, as in ‘ljmp’, ‘lcall’, etc. For example,
GAS syntax NASM syntax ========== =========== jmp *100 jmp near  call *100 call near  jmp *%eax jmp near eax jmp *%ecx call near ecx jmp *(%eax) jmp near [eax] call *(%ebx) call near [ebx] ljmp *100 jmp far  lcall *100 call far  ljmp *(%eax) jmp far [eax] lcall *(%ebx) call far [ebx] ret retn lret retf lret $0x100 retf 0x100
Segment-offset pointers are specified using the following format:
jmp $segment, $offset
jmp $0x10, $0x100000
If you keep these few things in mind, you’ll catch up real soon. As for more details on the GNU assembler, you could try the documentation.
I mentioned before that Windows XP does not allow concurrent sessions for its Remote Desktop feature. What this means is that if a user is logged on at the local console, a remote user has to kick him off (and ironically, this can be done even without his permission) before starting work on the box. This is irritating and removes much of the productivity that Remote Desktop brings to Windows. Read on to learn how to remove that limitation in Windows XP SP2
A much touted feature in SP2 (Service Pack 2) since then removed was the ability to do just this, have a user logged on locally while another connects to the terminal remotely. Microsoft however removed the feature in the final build. The reason probably is that the EULA (End User License Agreement) allows only a single user to use a computer at a time. This is (IMHO) a silly reason to curtail Remote Desktop’s functionality, so we’ll have a workaround.
Microsoft did try out the feature in earlier builds of Service Pack 2 and it is this that we’re going to exploit here. We’re going to replace termserv.dll (The Terminal Server) with one from an earlier build (2055).
To get Concurrent Sessions in Remote Desktop working, follow the steps below exactly:
- Download the termserv.zip file below and extract it somewhere. (You have to be registered to see the file)
- Reboot into Safe Mode. This is necessary to remove Windows File Protection.
- Copy the termserv.dll in the zip to %windir%\System32 and %windir%\ServicePackFiles\i386. If the second folder doesn’t exist, don’t copy it there. Delete termserv.dll from the dllcache folder: %windir%\system32\dllcache
- Merge the contents of Concurrent Sessions SP2.reg file into the registry.
- Make sure Fast User Switching is turned on. Go Control Panel -> User Accounts -> Change the way users log on or off and turn on Fast User Switching.
- Open up the Group Policy Editor: Start Menu > Run > ‘gpedit.msc’. Navigate to Computer Configuration > Administrative Templates > Windows Components > Terminal Services. Enable ‘Limit Number of Connections’ and set the number of connections to 3 (or more). This enables you to have more than one person remotely logged on.
- Now reboot back into normal Windows and try out whether Concurrent Sessions in Remote Desktop works. It should!
If anything goes wrong, the termserv_sp2.dll is the original file you replaced. Just rename it to termserv.dll, reboot into safe mode and copy it back.
The termserv.dl_ file is provided in the zip is for you slipstreamers out there. Just replace that file with the corresponding file in the Windows installation disks.
I’ve added in extra information from the comments below… thanks for all who researched! 🙂
